(64.) _Early Improvers of Sheep._--There cannot be a more certain sign of the rapid advances of a people in civilization and prosperity, than increasing attention to the improvement of live-stock. It tells of a population limited in regard to soil, and making every effort to remedy the want, by an economical doubling of the return for the usual outlay: for, while a tribe wanders at large, remaining at a particular place only so long as provender holds out, and, striking the tent, departs for some far-off field, so long will their flocks be suffered to roam neglected, and flourish or decay, as chance directs.

From the time of Jacob, the possibility of determining the nature of the offspring, by impressions on the parents, has been apparent to all; and the best means of perpetuating a good quality, or removing a bad one, have continued from time to time, to occupy the attention of patriotic individuals. As much appears to have been known about sheep two thousand years ago as at present, so true is it, that nothing new is to be met with; yet, that does not rob our modern improvers of their merits, for though they deserve little as inventors, they are to be admired for that strength of mind, and determined perseverance, which enabled them to rouse their fellows from their lethargy, and compel them to become in turn, benefactors of their country, and themselves. The signs of a good ram are concisely laid down by Varro, by Virgil in his third Georgic, and by Columella; and, though the Spanish n.o.bility were looked upon with wonder, (till eclipsed by our own extravagance,) in giving two hundred ducats, or fifty pounds for a ram; yet Strabo a.s.sures us, that in his day (under Tiberius), they gave more than three times that sum for one of the breed of the Coraxi, a Pontic nation, believed to have the finest fleece in the world.

The greatest recorded improvers of the sheep in ancient times were Lucius Columella, and his uncle Marcus Columella, Spaniards of distinction, who removed to Rome in the reign of Tiberius, and made agriculture the study and business of their lives. The former commenced his celebrated treatise on husbandry during the reigns of Tiberius, and Caligula, and appears to have finished it A.D. 55. It is a work which may be read with advantage even at present, as it abounds with much that is valuable, and is accessible to all through its English translation.[10]

[10] I allude to this, as the author of the work on Sheep, published by the Society for the Diffusion of Useful Knowledge, at page 123 of that book, laments the want of an English translation of Columella. An excellent quarto translation of his twelve books on Husbandry, and one on Trees, was published at London, in 1745.

(65.) _Modern Breeders._--It is only within a very recent period, that the mode of improving live-stock by skilful breeding, has been properly attended to. The perfection of breeding formerly, was to have cows in calf once a-year, and rear calves on as little milk as possible; and, even yet, there are only a scattered few who devote to it the attention it requires. The first, in modern times, who arrived at any thing like eminence in this department, was Joseph Allom, of Clifton, who raised himself by dint of industry, from a ploughboy, and for a long time contrived to keep his methods secret, being supposed by many to have bought his ewes in Lincolnshire, at the very time he was constantly bringing them from the Melton quarter of Leicestershire. Though possessing talent, he does not appear to have had education enough to avail himself of it, and accordingly never gained the extensive popularity which fell to the lot of his successors.

As the introducers of new and important plans of management in agriculture, are always rewarded by large profits, and the grat.i.tude of their countrymen, so none were ever more generously dealt with in either respect, than Mr Robert Bakewell, of Dishley, and Mr Ellman, of Glynde. The former, who may be said to have created a _variety_, considered that a tendency to acquire fat was the first quality to be looked to in an animal destined for the food of man; and on this, with him a fundamental principle, was based the whole of his proceedings.

Different opinions will of course be held on the merits of the theory on which he acted but all must acknowledge, that we are indebted to his skill and experience, for the exertions which have been subsequently made to improve the qualities of live-stock, in every district of the kingdom. It was by his example, in fact, that the farmers all over the country were stimulated to exertion, and be the system bad or good, it ought to have our veneration, seeing that it was the commencement of a new and most important agricultural era.

John Ellman derives his well-earned fame, from the zealous manner in which he improved the Southdown sheep, and spread them through the empire. Till he directed his attention to the subject, every thing connected with the management of the flock was left to chance, or at least to the guidance of farm-servants, with whom, of course, it could not be a matter of interest to select, or _sort_, suitable animals for the continuance of the race. He speedily, however, corrected this mismanagement, and aided by the introduction of turnip-feeding, in no long time, and without any admixture of foreign blood, materially improved the breed.

About seventy years ago, improvements also commenced in Scotland. Till then, in many parishes, no farmer could keep sheep through the winter, and no place was reckoned so fatal to these animals as the undrained, and unsheltered parish of Eskdale-Muir, in Dumfriesshire. At last one William Bryden rented the farm of Aberlosk, and soon, by the _original_ plan of draining, and building stone enclosures, made it, to use the words of his able biographer, Mr Scot of Selkirkshire, "like the land of Goshen, good for cattle which it is to this day."

(66.) _Varieties among Animals._--All organized matter is subject to variety. It may be doubted whether, since the creation of the world, there have ever occurred, either at the same, or at separate periods, two individuals in every respect perfectly alike. A plant, or an animal, may resemble the rest of its species in chemical const.i.tution, and in the number and situation of its organs, but is sure to differ from all in size, general configuration, and disposition of its parts: These shades of difference, endless though they are, may be referred to two leading causes--climate and descent; the former embracing deviations induced by temperature and resources of subsistence; the latter including changes occasioned by management, modes of breeding, and influence of s.e.x.

(67.) _Varieties induced by Temperature._--The influence of temperature extends chiefly to the _colour_ and _development_ of animals. In cold regions the skin of the human race is fair, and the person squat and stunted, but as we approach the equator, the hue becomes deeper and deeper, till it is jetty black, while at the same time, the stature attains nearer and nearer to the tallest proportions to which mankind seem naturally ent.i.tled. The animals of the arctic regions are, for the greater part of the year, covered with a clothing of the purest white, which is, however, in many of them, abandoned for one of deeper tints as the solar heat begins to gain the ascendant. But how very different do we not find the colours of intertropical animals. There vivid tints, and an almost metallic l.u.s.tre, pervade animated beings, from the coral in its submarine abode, to the gallinaceous birds, the c.o.xcombs of the forest. In this, as in every other department of nature, the most beautiful harmony, or, in other words, a union of what is pleasing to the eye, and suited for the comfort of the creature, every where prevails. The colour of an animal envelope is never at variance with the tints of surrounding objects. A painter, for example, would not place a flower or animal of brilliant hue amidst the monotonous aspect of an arctic landscape; neither would he picture the faintly-tinted beings of a polar lat.i.tude, as surrounded by the warm and flashy colouring characteristic of an oriental climate. As temperature, then, determines in a marked degree the colour and dimensions of every animal, such variations render the division of living beings into races and varieties, a matter of necessity. Thus all human beings belong only to one species, which may, however, be divided into five races, and these again into an infinity of varieties. The differences between a race and a variety are, that the latter is a subdivision of the former, and that in the former the modifications are more profound, the changes not being confined to the surface, but extending to the frame-work of the body; whereas, to const.i.tute a variety, nothing more is necessary than the superficial influence of heat and light on the skin, and its appendages the hairs. The Negro and the Abyssinian are precisely similar in colour, yet they are by no means of the same race, as their different features will distinctly prove; the Abyssinian approaching as much in cast of countenance to the European, as the negro does to the higher orders of the ape. The same may be noticed among sheep, but this is sufficient for the present.

The changes induced by climate, result from the working of a power inherent in most animals and vegetables, by which they are suited within certain limits, for bearing up against removal from their ordinary localities, and a.s.suming a different cast, as the place of their exile may differ in degree from that which they have left. This gradual adaptation to circ.u.mstances by an accommodating power is termed, in philosophical language, acclimation.

(68.) _Adaptation of the Sheep to Climate._--No animal varies more than the sheep, and none so speedily adapts itself to climate; it would almost appear that nature, convinced of its great utility, had bestowed upon it a const.i.tution so pliant, as to enable it to accommodate itself to any point in a wide scale of temperature; for though its natural situation as a wool-bearing animal, like that of man appears to be the wine countries, yet with him, it has spread to every quarter of the globe, becoming impressed at every change with some peculiarity, alterable only by a change of situation, and varying, we might almost affirm, with the weather; for, where the temperature is equable, there does the animal preserve unchanged an atmospheric stamp, and defies our efforts to alter the breed; while under a fluctuating sky we can model it at will, though in this case, continued exertions are required to secure them for any length of time in an undeviating course.

(69.) _Changes produced by Climate._--The wonderful power of temperature in effecting changes upon animals, is well ill.u.s.trated by the Portuguese, who, after a residence of three hundred years in India, are said to be at present almost as black as Caffres. Bishop Heber, speaking of India, says, "It is remarkable to observe how surely all these cla.s.ses of men (whites--Persians, Greeks, Tartars, Turks, and Arabians), in a few generations, even without any inter-marriage with the Hindoos, a.s.sume the deep olive tint, little less dark than a negro, which seems natural to the climate." Buchanan also in his travels through the same country, alludes to a tribe of black Jews who have, in all probability, been settled in the district ever since the period of the captivity under Nebuchadnezzar, 3000 years ago, and who retain all the national peculiarities of their race, with the exception of their colour, which is now as dark as that of the surrounding tribes. These examples, however, it may be affirmed, are not to the point, as embracing theories in regard to peculiar changes in an animal different from the sheep, but such objections are perfectly groundless, as what will affect colour in mankind, will lead to changes even of a more wonderful nature in the sheep, seeing that it is abandoned more entirely to such an influence.

(70.) _Temperature preferred by Sheep._--Sheep, though capable of thriving in a great variety of climates, seem to prefer such as are temperate, and in these only do they arrive at perfection. They are common on the Cordilleras at an elevation of from 3300 to 8200 feet, within which limits they propagate readily without any care; but the reverse is the case in hotter regions, it being difficult to rear lambs in the plains of Meta, and no sheep are to be met with from the river to the foot of the Cordilleras, though their skins, from being in demand for making parchment, sell as high as those of the ox. Sheep were at one time, according to Thunberg, the scarcest articles in Batavia, as their woolly coat rendered the heat of the climate quite insupportable; but this inconvenience was at last remedied by sending them, on their arrival from the Cape, further up the country, to the Blue Mountains, where the air is several degrees colder. The question then naturally occurs, if an elevation of temperature is, as in this instance, fatal to these animals, how do they happen to have spread over a vast tract of country in spite of such extremes? Simply for the reason, that when an animal is left to the exercise of its own free will, and the dominion of its instincts, it will not subject itself to the danger of an extreme in any thing. It will not traverse several hundred miles in a single season, and thus expose itself to sudden changes. The natural dispersion of all animals is gradual, so that their const.i.tutions are enabled, from the slowness of the transition, to accommodate themselves, by an alteration in covering and habit, to surrounding circ.u.mstances, which would, were the variations abrupt, speedily destroy it. The reason why a race of animals occasionally thrives so well in a country to which it may be removed, appears to lie in its being suited, I may say, accidentally, by peculiar conformation, to the temperature to which it is transplanted. There are some happy climates where, introduce what animals you will, no matter how stunted they are, or how different the degree of warmth may be, their offspring will thrive, proving large and vigorous, and every way worthy of being placed at the head of its species. These are, however, cases where the transition is from an extreme of heat or cold to a temperate atmosphere. Witness what Mr Dawson, the manager of the Australian Agricultural Company, says in his private journal (quoted in _Cunningham's New South Wales_). "Both the climate and the soil appear by nature intended to produce fine wool, and fine animals too, _even from the worst beginnings_. The latter seems a paradox. The extensive range afforded to every animal keeps it in good condition, and, perhaps, the natural gra.s.ses may have more of good in them than their appearance indicates. However this may be, the climate clearly has a wonderful effect on the size of all animals, even upon man, who is universally tall here, though born of diminutive parents. From this I am led to believe, that the climate governs chiefly, and thus every breeding animal introduced here will attain a size not known in Europe."

(71.) _Extent of the Alterations produced by Climate._--Changes occasioned by climate are always limited to the fleece, horns, and disposal of the fat, and never extend to those parts, on the permanence of which the animal depends for its station in the scale of being, as the feet, teeth, and digestive organs. In tropical countries we find the fleece approaching more to hair than wool, as in the sheep of Thibet, so celebrated for the silky nature of their coat. Burch.e.l.l remarks, that the skins he brought from the Cape of Good Hope were often taken for those of an unknown quadruped, from the _furry_ nature of their wool, if such it can be called, and thinks it is owing as much to the pasture, which is well adapted for giving these animals a soft and useful _fur_, though not suited, like New South Wales, for the growth of the finest wool, and that the colony might turn this to great advantage. In cold regions the hairy covering is more developed and fully coa.r.s.er, but always mingled with a proportion of hard rough wool. The influence of climate on portions of the fleece and skin is well ill.u.s.trated by circ.u.mstances which have occurred in Galloway, even within the limits of our traditionary writings.[11] The native sheep of the Highlands of that district is supposed to have been a small, handsome, _white-faced_ breed; at least so thinks John MacLellan, who wrote an account of Galloway in 1650, from the wool being much praised, and eagerly bought up by merchants, which would not have been the case if taken from the _black-faced_ animal; yet how happens it that at present the native breed exists only in the lower parts of Kirkcudbrightshire, the high country exhibiting _black-faced_ sheep, which, after every trial, have been found best adapted to the climate, and pasture of the moors and Highlands; while Chalmers owns that it has not been ascertained when or whence this hardy breed were brought to their present locality? Why, it is tolerably plain, that though the _white-faced_ sheep might be placed there originally, yet they would speedily lose every trace of their origin, and become _black-faced_ when placed on a hilly country, and subjected to the slow but certain influence of peculiar food and climate.

[11] Chalmers' Caledonia--Article, Galloway.

Mr Culley imagines, that the dun-faced sheep were the earliest tenants of the Scottish hills, but so far as my researches extend, that supposition is entirely contradicted. Chalmers remarks, that the black-faced animals superseded the goats, which were at one time a source of subsistence to the farmers, and it is exceedingly probable, that as the old white-faced began to change their appearance, and became gradually able to withstand the rigours of a mountain fare, and winter under a dun skin, and short rough wool, so would they recommend themselves as the best of all stock to the hard-driven agriculturalist.

(72.) _Increase of the Number of the Horns._--As much wonder is sure to be excited by the fact, that bony prominences are subjected with as great certainty to the modelling hand of climate as softer parts, I give the following from a recent work, ent.i.tled, "_Gardens and Menagerie of the Zoological Society Delineated_," premising, however, that, in my opinion, temperature has a vast deal more to do with alterations in the horns than domestication or cultivation. "One of the most curious modifications produced by cultivation in the domesticated sheep consists in the augmentation of the number of its horns; two, three, or even four supplementary appendages of this description being occasionally produced in addition to the normal number. Under these circ.u.mstances the additional horns usually occupy the upper and fore part of the head, and are of a more slender shape, and take a more upright direction than the others, thus approaching in character to those of the goats, while the true horns retain more or less of the spiral curve that distinguishes those of the sheep. There exists a strong tendency to the propagation of this monstrosity, which is extremely frequent in the Asiatic races, but is also met with in a breed that is common in the north of Europe, and is said to have been originally derived from Iceland, and the Feroe Islands. In this case it is unconnected with any other anomaly, but in the flocks of the nomad hordes of Tartary, it is usually combined with an enlargement of the tail, and adjacent parts, by the deposition of fat, frequently to an enormous extent."

(73.) _Causes of the various forms of the Horn._--Horns are seldom met with in the sheep of hot climates, occurring more frequently in cold and temperate regions; thus following closely the development of the other coverings, to which, as before stated (19), they are strictly a.n.a.logous. The fleece consists of two portions--hair and wool, the one predominating more or less over the other, as the climate may direct.

The form of the horns is always in unison with the character of the fleece: thus, if the animal is covered with hair, as in the goat, the horns will be straight; but if it is clothed with wool, as in the sheep, the horns will be curved. The same holds good in other animals.

The reason of this appears to lie in the tendency which the hair or wool, const.i.tuting the h.o.r.n.y sheath, has to model the form of the supporting bone. The fibre of hair is nearly straight; that of wool is, on the other hand, remarkable for the number of tufted curls, or small spiral ringlets, into which it naturally contracts; so that a Merino ram, for example, will never be found with rectilinear horns, nor a true goat with twisted ones. The truth of these remarks is borne out by observations on animals on whose heads more than two horns are occasionally met with. We always in such instances notice, that the additional horns are straight, thus indicating the presence of a considerable quant.i.ty of hair among the wool. The curve will be more decided, and the twists more numerous, in proportion as the fibre comes nearer and nearer to a perfect wool--evidence of which we have in the beautifully-tufted and spiral horns of the Merino ram, which are as opposite in this respect to those of the goat, as is its fleece to the hairy coat of the latter. From these considerations I am led to believe, that the form of the horn, when present, is an excellent guide to the nature and quality of the other coverings, and an index to every gradation which can possibly occur between wool and hair.

(74.) _The proper Temperature required for Sheep._--Regular warmth is absolutely necessary for the production of a good animal and a fine fleece, and is only to be obtained by attending to the draining and clearing of land, so as to dissipate moisture, and allow currents of air to play freely across the country.[12] An atmosphere which holds suspended a large quant.i.ty of watery vapour, is always extremely chilling to an animal body. This is accounted for by the well-known fact, that a moist air, being a better conductor of caloric than a dry one, robs an animal more quickly of heat. Thus, in pa.s.sing from the dry air of the hills into the vapour of the valleys in a winter morning, we feel as if the transition had been from a temperate to an icy region.

Hence one of the reasons why sheep thrive best in a rather elevated situation. Moist air, however, is exceedingly oppressive in hot weather, because evaporation, from the surface of the body, is to a great extent diminished; and it is only by the perspiration being allowed to escape rapidly, and to convey away the heated particles, that we can manage to be in any degree comfortable during the heat of summer. This free evaporation we endeavour in every way to obtain, and often in a manner that ignorant people would consider as the reverse of sensible. It is well known that draughts of _cold liquids_ are very far from answering the purpose of lowering our temperature when above a pleasant standard; but we find that a basin _of hot soup, or tea_, will speedily bring about the desired end, by producing a copious determination of fluid to the skin. Yet, if the air contained no moisture, we should experience sensations just as unpleasant as those already mentioned; for evaporation from our bodies would proceed at such a rate, that we would soon be parched. It is to counteract this tendency of dry air that the Americans are in the habit of placing a small vessel of water on their stoves, by which contrivance a quant.i.ty of vapour is diffused through the apartment, sufficient to balance the loss from the arid warmth of the fire.

[12] It is to secure equality of temperature that the Spanish flocks are twice in the year exposed to the hazard of an overland journey of 400 miles, that they may pa.s.s the summer in the mountains of the north, and the winter in the southern plains.

That an equable temperature is only to be obtained by draining and clearing a marshy and wooded country, is sufficiently authenticated. In the thickly wooded and swampy territories of Guiana, rain falls continually during nearly eight months of the year; and the cold is so intense, that fires are necessary in the houses throughout the night.

But in Cayenne and its neighbourhood, which were cleared of wood about one hundred and fifty years ago, the increase of temperature is now so great, that during the night the people are annoyed by the warmth, and the rains are neither so frequent nor so heavy as in the rest of the country. Paris and Quebec are nearly under the same lat.i.tude; yet the air of the latter is much colder than that of the former, evidently from its being surrounded by forests so dense and umbrageous, that sun and wind are alike denied access to the earth. The difference between a cleared and an uncleared country, in regard to wool, is well ill.u.s.trated, by contrasting North America, its heavy woods and stagnant atmosphere, with the thinly timbered surface and constantly renovated air of New South Wales. It is only within the last few years that Canada has been enabled to compete with Britain in the article of wool, and that the sheep, which were of the coa.r.s.est kind, have been so improved as to do away with the prejudices against their mutton.

Australia, on the other hand, has, from its earliest colonization, figured as a sheep-rearing country of the first importance; and nothing has conduced so much to this as its freedom from closely planted trees, by the absence of which the settler is enabled at once to stock his farm with the best of sheep. Nature, in fact, could never have intended sheep to pasture in a wooded country, as is clearly evinced by their coat, to which every thing in the shape of bush or tree is in the highest degree inimical.

(75.) _Geographical limits of the Sheep._--Every plant and animal has certain geographical limits, out of which it cannot exist. With the exception of man and the dog, no animal has a wider range than the sheep, extending as it does from Iceland almost to the equator, and from a few degrees south of that to the polar extremity of South America. But though existing under so great a variety of exposures, it must not be inferred that it can come to perfection in them all. On the contrary, it rather delights in the temperate zones, and can evidently only be raised to its highest point of excellence in the countries of the vine. The western parts of continents produce better sheep than the eastern, and the southern hemisphere better than the northern; as in the former situations the temperature is more nearly equable than in the latter. The same may be said of maritime districts, as compared with such as are inland. Temperature is affected in the same way by elevation as by northern or southern position--the mean heat diminishing in the same ratio when ascending a mountain, as in receding from the equator. On this account, Humboldt compared the earth to two mountains with their bases at the equator, and their summits at the poles. The mean temperature, when resulting from the height of the place above the level of the sea, is at the same time influenced by the nature of the aspect, as we notice in the Alps, where the Glacier exists on the northern side, at the same elevation at which the vineyard yields a perfect fruit upon the southern.

(76.) _Particular forms induced by certain limits._--The character which a predominance of heat, or cold, impresses on the animal as a whole, extends also to individual parts of the body. The sheep of South Africa are, as all the world know, remarkable for the magnitude of the tail, which forms an immense fatty appendage. The sheep of Persia, Tartary, and China, are distinguished from all others by the tail forming a _double globe_ of fat. The North of Europe, and North of Asia, are overrun by a breed in which the tail is almost wanting, while that of Southern Russia, India, and Guinea, stands pre-eminent from the elongation of the tail, and, in respect to that of the two last named places, also of the legs.

(77.) _Influence of vegetation on form and disposition._--Vegetation influences, to a great extent, the form and disposition of the animal.

Such changes may be brought about either by the plenty, or scarceness, of the herbage; or by the nature of the country on which that herbage is produced. Animals found on hilly countries are always widely different from those of the plains. Their bodies are light, their legs long, and their habits of that unquiet kind which renders them hostile to any thing like restraint. It is for these reasons, that when once a flock attaches itself to a range of hills, and becomes suited to the means of subsistence, it may preserve itself for ages apart from neighbouring varieties, and present, after a long series of years, those qualities in their native purity for which it was noted by the earliest observers. The sheep of a level country are distinguished, on the contrary, by heavy bodies, short legs, and easy tempers. They are, in fact, constructed on Dutch proportions, and are imbued, as a natural consequence, with those imperturbable and steady-going habits so characteristic of the bulbous bottomed Hollander. Subdued as they are by the nature of their locality, they readily submit to man, who tutors them at will, and works on them those profitable changes from which have originated our improved varieties. As connected with the unquiet dispositions of hill sheep, I may mention the prevalence of a notion, that domesticated sheep cannot by any possibility become wild. From all that I have seen, and read, I am led to believe, though the sheep, according to Greek, Roman, and Oriental philosophers, was the first animal domesticated, that when at liberty it will soon return to its primitive and instinctive habits. Bonnycastle, in his work on Spanish America, remarks, that sheep are found in a state of nature, in the northern parts of New Spain, "having multiplied to an extraordinary degree in the wide-spread plains, and savannahs." In ascending our Scottish mountains, every one must observe the state bordering upon wildness, in which the sheep appear, roving in detached but well-led parties; bounding away to the most inaccessible places on the approach of danger, and peering from the eminences in all the pride of scornful independence. Professor Blumenbach at one time doubted the possibility of domestic sheep ever becoming wild; but his opinion was changed on perusing the work of Vincentius, where there occurs a remarkable pa.s.sage, in which Nearchus, when speaking of the desert island of Cataia, on the coast of Caramania, says, that the inhabitants of the neighbouring islands yearly carried thither sheep, as offerings to Venus and Mercury, and that, in course of time, they became wild in the deserts.[13] Constant attendance is, therefore, called for on the part of man, to ensure that untroubled reliance on his care so conducive to the welfare of the flock, for even on a temporary cessation of his protection, those instincts, which can be subdued but not eradicated, are brought into operation, and their presence will go far to r.e.t.a.r.d the advancement of those qualities, on the perfection of which a profit can alone be hoped for.

(78.) _Breeds required for Britain._--Of the numerous breeds at present in our island, a few only are indispensably necessary for the continuance of its prosperity. These stand, according to Marshall, thus:--A very long-woolled sheep, as the Lincolnshire, or Teeswater, for the richest gra.s.s lands, and finest worsted manufactures--the New Leicester, for less fertile gra.s.s land, and for rich enclosed arable land, on which the fold is not used; intended to supply coa.r.s.er worsted, stockings, coa.r.s.e cloths, blankets, and carpets--a middle-woolled breed, as the Wiltshire, the Norfolk, or the Southdown, for arable lands on which folding is practised, and for cloths of middle qualities--a fine-woolled, as the Ryeland, for the finest cloths; and a hardy race for heathy mountains.

Some argue, and rightly, that only three breeds are necessary for Scotland, inasmuch as only three are required by the nature of the country. Scotland may be regarded, in an agricultural point of view, as divided into highland, upland, and plain. The highland consists of primitive rocks, covered by peaty soil and heath, on which these indefatigable gleaners, the black-faced sheep, alone can gain a subsistence. The upland is formed by the transition series of rocks, covered with gra.s.s; and to it the Cheviots appear indigenous. The plain is formed by alluvial deposits, covered with rich pasture, and capable of supporting races of large sheep, as the Leicesters.

Sheep are the only kind of live-stock which ought to be kept in mountainous districts, especially when green crop cannot be cultivated. Sheep-farming must necessarily prevail in the Highlands, where there are few tracts suited for the pasturage of black cattle: The value of its adaptation to the natural circ.u.mstances of that district is proved by the rapid progress which it made, and the profits which resulted to the individuals with whom it originated.

Places which formerly were not of the slightest utility, now yielded heavy rents. The spots among the mountains, susceptible of cultivation, were found to be advantageously kept in gra.s.s, to serve as pasture for the flock during the rigour of winter, and it was well ascertained that more than double rent might be paid by stocking with sheep in preference to cattle.

The Dishley sheep are excellent specimens of what may be done with the form of an animal, when the endeavours of the breeder are seconded by a pasture suitable for the intended breed. They are admirably adapted, as every breed ought to be, to the soil and situation where they were called into existence; and their crosses are now spread over most part of the country; princ.i.p.ally the corn districts, as they are supposed to be the most profitable kind on farms where the best tillage crops are combined with the fattening of livestock, though Marshall supposes they will only be reckoned profitable so long as other breeds of long-woolled sheep remain with thin chines, and loose mutton; or, in other words, that there are plenty of kinds which would prove equal, if not superior, to the present, if they only received the same studied attention.

(79.) _Varied nature of the food of Sheep._--Sheep will take, sometimes from choice, sometimes from necessity, to food of a directly opposite nature to what they have been used. "The mutton," says the Rev. George Low, writing of Orkney, "is here in general but ordinary, owing to the sheep feeding much on sea-ware, to procure which these creatures show a wonderful sagacity, for no sooner has the tide of ebb begun to run, but they, though at a great distance, immediately betake themselves full speed, one and all, to the sh.o.r.e, where they continue till it begins to flow." The sheep of Iceland are content during severe winters to feed, and be preserved, on messes of chopped fish-bones, being all that the ingenuity of their masters can provide in the way of a precarious sustenance. During the long continuance of snow-storms, when the herbage is beyond the reach of their utmost efforts, sheep are known to devour the wool on each other's backs, and, in some instances to acquire a relish for this unnatural food, which adheres to them through life. This, though on first thoughts hardly credible, is scarcely more wonderful than the partiality which cows display, when instigated by the depraved appet.i.tes created by pregnancy, for blankets, and any similar domestic articles which may be exposed to the gratification of their longings.

The Puruk sheep of Ladusk, in the Himalaya mountains, is, as described by Mr Moorecraft, in the _Transactions of the Asiatic Society_, in respect to the varied nature of its food, a most remarkable animal.

"The Puruk sheep, if permitted, thrusts its head into the cooking pot, picks up crumbs, is eager to drink the remains of a cup of broth, and examine the hand of its master for barley, flour, or a cleanly picked bone, which it disdains not to nibble; a leaf of lettuce, a peeling of turnip, the skin of the apricot, give a luxury; and the industry is indefatigable with which this animal detects, and appropriates substances, so minute and uninviting as would be unseen and neglected by ordinary sheep; perhaps the dog of the cottager is not so completely domesticated as it is." That Mr Moorecraft is correct in this statement of its omnivorous propensities, there cannot be the slightest doubt, as any farmer can testify from what he has seen of lambs reared by children for amus.e.m.e.nt. The celebrated John Hunter showed, that a pigeon might be made to live on flesh, and that its stomach became adapted to the nature of this food: and I have somewhere read of a sheep, which, after being long on ship-board, and accustomed, from scarcity of vegetables, to an animal diet, could never after be prevailed upon to take to gra.s.s. Nor need these circ.u.mstances excite surprise, since the food of every living creature is, for a certain period at the commencement of existence, limited to such as is purely animal. But to keep to our subject. Those in the habit of opening the stomachs of sheep, must have remarked the eroded appearance which the inner coat occasionally presents. This phenomenon is owing to the action of the gastric juice, which, if competent to turn at once from the food with which it is mingled to attack the texture which has secreted it, will also be, during life, capable of digesting with tolerable ease, such dead animal matter as may be brought into contact with it.

In regard to vegetable food, they will, when necessary, devour such as is even of an acrid nature, and calculated to poison any animals but themselves. Thunberg, while in Southern Africa, frequently noticed sheep eating, with impunity, the _Mortimia acris_, the _Rhus lucidum_, and the _Lycium afrum_, which are all of a poisonous nature; and, in this country, hemlock is known to be quite innocuous to sheep. What is poison to one animal often const.i.tutes a wholesome food for others, and that which will, when given in immediate large doses, destroy an animal, will, when taken in a gradually-increasing allowance, prove extremely salutary.

(80.) _Influence of the food on the quality of Mutton._--Diet has a powerful influence on the const.i.tuents of the body. A rank succulent pasture taints the flesh, or renders it insipid and unpleasant, while a dry aromatic herbage communicates a delightful flavour, and enables people versed in the pleasures of the table easily to discriminate between turnip-fed and gra.s.s-fed mutton; and again, between the latter, and that which has spent its existence on the hills. In Touchwood's Syllabus of Culinary Lectures, appended to the _Cook and Housewive's Manual_, by Mistress Dods, we are briefly informed, that "the black-faced, or short-sheep, are best for the table, though _more depends on the pasture than the breed_." More, in fact, depending on feeding and management, than on the variety of the animal, though this of course is not to be neglected. A notion has been advanced in this country, that artificial pastures are less nutritious than natural ones, and that the animals which are raised upon them are, consequently, of a laxer fibre, and the flesh less wholesome, as well as less savoury. This, I have no doubt, is perfectly correct, as many _diseases_ may be traced to such improper food, and what is calculated to produce in some cases actual disease, cannot fail to prove at all times capable of r.e.t.a.r.ding the advancement of the animal. These soft succulent pastures appear not to be positively poisonous, but to be negatively so from their deficiency in saline matter; the rapid growth of the plant preventing the elimination and absorption, of many of these ingredients with which the soil abounds. This is proved by the greater necessity which exists for the use of salt in the food of the herbivorous animals of hot climates, than in that of such as inhabit temperate, or cold lat.i.tudes; vegetation being in the former more rapid in its details, and in certain states of the atmosphere hurried in the extreme, while in the latter the process proceeds with that leisure which enables the plant to make good the measure of its const.i.tuents, as it increases in size. In many parts of North America it is well known, that, at certain seasons, the wild animals make eagerly for the salt _licks_; and, following up this hint, the settlers easily induce their oxen to keep near their dwellings, by serving them periodically with salt. When the wild cattle of South America had greatly increased, it was discovered that they could not exist unless they had access to streams which had acquired brackish particles from the soil. _If salt, in places devoid of it, was not furnished to them by man, they became stunted, unfruitful, and the herds soon disappeared._ Even in this country, the free use of salt is found to be highly beneficial to our domestic animals, preventing the occurrence of many of those diseases which are otherwise sure to follow the use of food such as is mentioned above, and ensuring that sound health which is so conducive to the acc.u.mulation of fat.

(81.) _Differences in the quality of Mutton._--I shall now enter a little into the manner in which the _quality_ of the flesh may be affected, and the methods of judging of the different states or conditions, in which it may be found under various circ.u.mstances; premising that it requires much experience, to enable a person to p.r.o.nounce with confidence, as to the value of the muscular parts, from the inspection of a living animal:--The flesh of different specimens of the same animal, varies not so much from breed or descent, as from age, feeding, and exercise. That of the young is soft and gelatinous, the fibres being small, weak, and much interspersed with a substance termed, from its loose appearance, cellular tissue. This tissue exhibits in the s.p.a.ces between the muscles (_layers of flesh_) small ma.s.ses of delicate fat. The greater bulk of the latter is situated immediately beneath the skin, and occasions that beautiful rotundity so much admired in children. As the animal advances in life, the fibres become firmer, larger, and more approximated, the cellular tissue disappears to a great extent, the fat shifts from the outward to the inward parts, allowing the outline of the muscles to be distinctly seen, but giving at the same time to the figure that portly symptom of good keeping, so unpleasant to the eye when carried to the extent of Aldermanic dignity. All these appearances are, however, varied by exercise, which tends, in a marked degree, to increase the muscular parts at the expense of the fat--the former becoming, when employed within proper limits, large, and unyielding to the touch, while at the same time the colour is heightened from a pale or purple hue, to the bright vermilion so justly relied upon by housewives, as a guarantee for the superior qualities of the article. The wild horses in South America, which form the princ.i.p.al part of Indian diet, are said by these epicures to be much improved for the table by gentle labour, and to be quite on a par when thus cared for, with some of our best beef. This plan is, however, only pursued for the purpose of rendering the flesh of their horses moderately firm; but where an opposite effect is desired it is readily, though cruelly, produced by putting the animal to a lingering death; examples of which practice are to be met with in the annals of most civilized nations; as in the German mode of whipping pigs, and the English custom of baiting bulls;[14] both tending to the same end, by so exhausting vital contractibility as to prevent its last and faint display in the stiffening of the carca.s.s.

[14] By the old English law, no bull beef could be sold unless the bull had been baited.

Marshall, who touches very slightly on the subject, says, "The flesh of sheep when slaughtered is well known to be of various qualities: some is composed of large coa.r.s.e grains, interspersed with wide empty pores, like a sponge; others of large grains, with wide pores filled with fat; others of fine close grains with smaller pores filled with fat; and a fourth of close grains without any mixture of fatness. The flesh of sheep when dressed is equally well known to possess a variety of qualities: some mutton is coa.r.s.e, dry, and insipid,--a dry sponge affording little or no gravy of any colour. Another sort is somewhat firmer, imparting a light-coloured gravy only. A third plump, short, and palatable, affording a mixture of white and red gravy. A fourth likewise plump, and well-flavoured, but discharging red gravy only, and this in various quant.i.ties. It is likewise observable that some mutton, when dressed, appears covered with a thick, tough, parchment-like integument; others with a membrane comparatively fine and flexible." This membrane ought to be rather thin than thick, as, when of the latter texture, you may safely affirm that the animal was aged. _Looseness_ is reckoned a bad quality of the flesh of sheep during life, as indicating a coa.r.s.e-grained porous mutton, and as equally exceptionable with that of _hardness_: while _mellowness_, and firmness, are much to be desired, as forming a happy mixture, deemed by some the point of perfection. The tendency to become fat at an early age, though a valuable one in some points, is not so in others.

Premature decay is always the result, showing with certainty that a healthy action has not been going on. An animal when _loaded_ with fat cannot be looked upon otherwise than as in a diseased state, and liable to embara.s.sment of many organs, especially of the heart and brain. Sudden death on any hurried exertion is far from rare, and life, from the difficulty of enjoying it, is any thing but desirable.

(82.) _Abuses in Feeding._--The custom of over-feeding was carried to an absurd extent on the promulgation of Bakewell's method, nothing less being aspired to than the glory of laying seven or eight inches of fat on the ribs of sheep. This folly however had its day: the ridiculous parts of the system have to a great extent disappeared, while attention to the production of an increased quant.i.ty of mutton, without too great an abundance of fat, has remained to prove to the world the value of the benefits which the English farmer conferred upon his country. Overgrown sheep are indeed good for nothing "save"

in the words of Meg Dods, "to obtain premiums at cattle shows, and deluge dripping-pans with liquid fat;" and in this every one will agree, excepting always boarding-school cooks, and others who depend for their princ.i.p.al perquisites on the over-roasting of oily meat! The fat, though not reckoned as offal in the slaughter-house, will speedily show itself as such in the kitchen, by the waste during the cooking process, even in England where fat meat is so much admired; and it is surely absurd to pay the price of good mutton for tallow, when if the latter were really wanted, it could be procured at a cheaper rate by itself, than when forming part of a dear commodity.

The only way in which over-fat meat can at all be reckoned profitable, is in its application to the wants of the working cla.s.ses, whose bodily labour enables them to enjoy what would to others prove displeasing in the extreme, and to digest and a.s.similate with ease, food which to the sons of sloth would prove a poison. So far as these wants have been supplied, the attempt of Bakewell has been attended with the happiest results, as he and his disciples have placed by their well-spent exertions much good food within the reach of the poorer cla.s.ses, which they must otherwise have gone without; while in many instances it has driven bacon from the market, being a cheaper and more palatable commodity, which cannot but contribute to the health of the people, seeing the continued use of salted meat is calculated to injure the body, and render it liable to many diseases.

Marshall remarks, that fat, like charity, covers a mult.i.tude of faults: and he is right, for an ill-shaped animal if well fed, has all its angles speedily effaced, and if its ugliness has not amounted to absolute deformity, it acquires that rotundity of contour so pleasing to the eye, and so apt to mislead us.

The rapidity is various with which animals take on fat, much depending on hereditary predisposition, and the nature of the food; and much also on the state of the atmosphere, and quiet habits; a moist and rather warm air tending greatly to the advancement of the process, some birds becoming fat in twenty-four hours of wet weather. Children that have been emaciated by diseases often resume their original plump condition in a few days; and animals that have been famished, as hogs, afterwards fatten very rapidly. Moderate and repeated bleedings, mild farinaceous diet, and emasculation conjoined, tend to the repletion of the body, and to the speedy deposition of fat; yet it would appear, that when acquired in this rapid manner, it never possesses the value in a culinary point of view, that is yielded to such as has been slowly formed, when, as one may say, the worthless particles have had time to be removed, and the remaining part to become a firm and healthy deposit. It is partly owing to this, that animals are never at their best when forced to take on fat at an early age, but are most esteemed by the gourmand when they, as in the case of the sheep, have lived from three to four years.

(83.) _Tendency to acquire Fat._--A disposition to early obesity, as well as a tendency to that form which indicates a propensity to fatten, is materially promoted by a good supply of rich food, while the animal is in a growing state. The Spanish shepherds are so well aware of this, that half of the lambs are annually killed, that the survivors may obtain every indulgence in the way of milk. Care should be taken never to place animals suddenly on food much superior in feeding qualities to what they have left. Very lean sheep are never put to full turnips in winter, nor to rich pastures in summer, but are prepared for turnips on good gra.s.s lands, and kept on second years'

leys, and afterwards given a moderate allowance of turnips if they are to be fatted on pastures. It is an invariable rule with all good managers, never to allow this or any other animal, reared solely for the shambles, to lose flesh from its earliest age till it is sent to the butcher as more food is necessary to bring it to a certain condition than to keep it at it. In the case of the Dishleys, it is customary to keep all in a state of fatness, except those intended for breeding, and after full feeding on turnips during winter and spring, to finish them on the first year's clover early in summer, when the prices of meat are usually the highest; so that this variety is always fit for market at eighteen months, while the Highland breeds, though prepared by means of turnips, a year at least, sooner than in former times, do not usually go to the shambles till from three to four years old.

(84.) _Frequent change of Pasture necessary._--Sheep ought never to be permitted to remain too long on one pasture:--Great benefit will be derived from their removal from time to time to different parts even of the same farm, by which arrangement a change of herbage will be ensured. No animal can be kept for any length of time in health, if restricted to one unvarying routine of diet. This has been satisfactorily proved by the experiments of Majendie, who found that health could not be sustained on one or even two kinds of food beyond the thirtieth day. Now, though such immediate injury cannot result to a flock from retention on a particular pasture, owing to the variety of sustenance being considerable, yet proportional harm will ensue sufficient to induce us not to repeat the risk. Nature, the best of guides in all that relates to the protection of her creatures, is no where more pointed in her directions than on this head. A necessity for a variety of food, and a desire to secure it, are implanted in the disposition of every animal; and where is the creature more p.r.o.ne to extensive rambles than the sheep? We limit it to a paltry pasture-ground of roods and acres, but does it not show, by its determination to transgress our barriers, that such is not the treatment nature has designed for it? There is something more than wildness of character, and restless disposition, in the powerful attempts it continually makes to defy our artificial boundaries. There is in these efforts a longing for fresh fields and other herbage, an instinctive feeling that all is not as it ought to be; and yet we attend not to the hint! Nothing will conduce so much to the health of the sheep, and to the speedy taking on of fat, as the frequent shifting of the flock. Disease will doubtless still affect the animals, but illness will be rare, and mortality diminished, if by the care of their rulers, they are enabled to obtain what instinct tells them is the best of medicine.

(85.) _Varieties induced by apparently trivial causes._--Surrounded in a civilized state, by all that can minister to the supply of wants, whether real or supposed, man is not on that account to be imagined as always so situated. Look to savage nations, and remark their dest.i.tute condition, their dependence on the uncertain proceeds of the chase, and their reliance on modes of agriculture as unprofitable as they are unmatured. Countries there are certainly to be found, where the "elements of temperature," are so fortunately balanced and combined as to produce only good effects, and in which the rude inhabitants reap the fruits of a spontaneous plenty; but these form only a small proportion of the globe, and in most regions man must give his unceasing endeavours to the cultivation of a plant or animal, before he can raise it from the miniature condition in which he finds it, to such a size and richness as will satisfy his wants. Nor need we go far for ill.u.s.trations. The crab has been transformed into the apple, and the sloe into the plum. None of our cereal gra.s.ses, as now cultivated, are to be met with in a wild state; they have evidently been brought to their present fulness by the care of ages. The red cabbage and the cauliflower are the altered descendants of a widely different sea-side plant. The different races of cabbages are examples of a wonderful deviation from the natural type, and they all require much nicety in cultivation to prevent them a.s.suming the characters of the original stock, as, when permitted to grow wild, especially on a sterile soil as that of the sea coast, they are sure in no long time to become exact counterparts of their originals. Cultivation, also, though taken in rather a different sense, influences to a great extent the form and features of animals. In proof of this may be adduced the differences that exist between different ranks of inhabitants in almost all countries. Buffon says, that in France you may distinguish by their aspect not only the n.o.bles from the peasantry, but the superior orders of n.o.bility from the inferior--these from citizens, and citizens from peasants. The African field-slaves in America, are extremely different from the domestic servants of the former nation, retaining as they do their original peculiarities from poor living and degrading duties; while the latter have nearly approached to the habits and modes of thinking of their masters, from living with them, and being well treated under the same roof. "The South Sea islanders," says Dr Elliotson, "who appear to be all of one family, vary according to their degree of cultivation. The New Zealanders, for example, are savages, and chiefly black; the New Hollanders half civilized, and chiefly tawny; the Friendly islanders are more advanced, and not quite so dark; several are lighter than olive colour, and hundreds of European faces are found among them." Indeed the examples are almost endless which I could bring forward to aid my explanations; but these it would be needless to give, since it is in the power of every one to study the differences in form and features of the cla.s.ses of society in our own island, and by so doing understand the influence of otherwise trivial and unimportant circ.u.mstances, on an animal at all times so easily moulded to situation as the sheep.

(86.) _Varieties from mode of Breeding._--Changes are wrought for the most part by attention to the mode of propagation of the plant or animal, by the plan of crossing; and by careful selection of the parent stock. Every one must be struck with the varieties constantly occurring in the vegetable world: Flowers change their colours, and become double; and these characters can be perpetuated by seed.
