"The suspicion that the cholera was caused by poisoning the wells was universal among the peasantry of the counties of Zips and Zemplin, and every one was fully convinced of its truth. The first commotion arose in Klucknow, where, it is said, some peasants died in consequence of taking the preservatives; whether by an immoderate use of medicine, or whether they thought they were to take chloride of lime internally, is not known. This story, with a sudden and violent breaking out of the cholera at Klucknow, led the peasants to a notion of the poisoning of the wells, which spread like lightning. In the sequel, in the attack of the estate of Count Czaki, a servant of the chief bailiff was on the point of being murdered, when, to save his life, he offered to disclose something important. He said that he received from his master two pounds of poisonous powder, with orders to throw it into the wells, and, with an ax over his head, took oath publicly, in the church, to the truth of his statement. These statements, and the fact that the peasants, when they forcibly entered the houses of the land-owners, every where found chloride of lime, which they took for the poisonous powder, confirmed their suspicions, and drove the people to madness. In this state of excitement, they committed the most appalling excesses. Thus, for instance, when a detachment of thirty soldiers, headed by an ensign, attempted to restore order in Klucknow, the peasants, who were ten times their number, fell upon them; the soldiers were released, but the ensign was bound, tortured with scissors and knives, then beheaded, and his head fixed on a pike as a trophy. A civil officer in company with the military was drowned, his carriage broken, and, chloride of lime being found in the carriage, one of the inmates was compelled to eat it till he vomited blood, which again confirmed the notion of poison. On the attack of the house of the lord at Klucknow, the countess saved her life by piteous entreaties: but the chief bailiff, in whose house chloride of lime was unhappily found, was killed, together with his son, a little daughter, a clerk, a maid, and two students who boarded with him. So the bands went from village to village; wherever a n.o.bleman or a physician was found, death was his lot; and in a short time it was known that the high constable of the county of Zemplin, and several counts, n.o.bles, and parish priests, had been murdered. A clergyman was hanged because he refused to take an oath that he had thrown poison into a well; the eyes of a countess were put out, and innocent children cut to pieces. Count Czaki, having first ascertained that his family was safe, fled from his estate at the risk of his life; but he was stopped at Kirtchtrauf, pelted with stones, and wounded all over, torn from his horse, and only saved by a worthy merchant who fell on him, crying, 'Now I have got the rascal.' He drew the count into a neighboring convent, where his wounds were dressed, and a refuge afforded him. His secretary was struck from his horse with an ax, but saved in a similar manner, and in the evening conveyed with his master to Leutschau."[31]

[31] Quoted from an address delivered in Boston by Edward Everett.

A little knowledge on the part of the peasantry would have prevented these horrible scenes. Had they learned even the elements of physiology and chemistry, they would have known that cleanliness is essential to health at all times, and that during the prevalence of a malignant epidemic it is doubly needful. They would have known, also, that chloride of lime is not a medicine to be taken internally, but that it is very useful for disinfecting offensive apartments, and that its tendency, when properly used, would be to counteract the cause of the disease which they so much dreaded.

Among all nations, and in all ages of the world, ignorance has not only debarred mankind from many exquisite and sublime enjoyments, but has created innumerable unfounded alarms, which greatly increase the sum of human misery. In the early ages of the world, a total eclipse of the sun or of the moon was regarded with the utmost consternation, as if some unusual catastrophe had been about to befall the universe. Believing that the moon in an eclipse was sickening or dying, through the influence of enchanters, the trembling spectators had recourse to the ringing of bells, the sounding of trumpets, the beating of brazen vessels, and to loud and horrid exclamations, in order to break the enchantment, and to drown the muttering of witches, that the moon might not hear them. Nor are such foolish opinions and customs yet banished from the world.

Comets, too, with their blazing tails, were long regarded, and still are by many, as harbingers of divine vengeance, presaging famines and inundations, or the downfall of princes and the destruction of empires.

The northern lights have been frequently gazed at with similar apprehensions, whole provinces having been thrown into consternation by the fantastic coruscations of these lambent meteors. Some pretend to see in these harmless lights armies mixing in fierce encounter and fields streaming with blood, while others behold states overthrown, earthquakes, inundations, pestilences, and the most dreadful calamities.

Because some one or other of these calamities formerly happened soon after the appearance of a comet or the blaze of an aurora, therefore they are considered either as the causes or the prognostics of such events.

Popular ignorance has given rise to the practice of _judicial astrology_; an art which, with all its foolish notions so fatal to the peace of mankind, has been practiced in every period of time. Under a belief that the characters and the fates of men are dependent on the various aspects of the stars and conjunctions of the planets, the most unfounded apprehensions, as well as the most delusive hopes, have been excited by the professors of this fallacious science. Such impositions on the credulity of mankind are founded on the grossest absurdity and the most palpable ignorance of the nature of things; still, in the midst of the light of science which the present century has shed upon the world, the astrologer meets with a rich support[32] even in the metropolis of Great Britain; and soothsayers, if not astrologers, get great gain by their craft in various portions of the United States. The extensive annual sale of hundreds of thousands of copies of almanacs that abound in astrological predictions in the United Stales and in Great Britain, and the extent to which they are consulted, affords a striking proof of the belief which is still attached to the doctrines of this fallacious science, and of the ignorance and credulity from which such a belief proceeds.

[32] See Appendix to d.i.c.k's Improvement of Society, p. 338.

Shooting stars, fiery meteors, lunar rainbows, and other atmospherical phenomena, have likewise been considered by some as ominous of impending calamities, but they are regarded in a very different light by scientific observers. The most sublime phenomenon of shooting stars of which the world has furnished any record was witnessed throughout the United States on the morning of the 13th of November, 1833. This astonishing exhibition covered no inconsiderable portion of the earth's surface. The first appearance was every where that of fire-works of the most imposing grandeur, covering the entire vault of heaven with myriads of fire-b.a.l.l.s resembling sky-rockets; but the most brilliant sky-rockets and fire-works of art bear less relation to the splendors of this celestial exhibition than the twinkling of the most tiny star to the broad glare of the noonday sun. Their coruscations were bright, gleaming, and incessant, and they fell thick as the flakes in the early snows of December. The whole heavens seemed in motion, and suggested to some the awful grandeur of the image employed in the Apocalypse upon the opening of the sixth seal, when "the stars of heaven fell unto the earth, even as a fig-tree casteth her untimely figs when she is shaken of a mighty wind."

While these scenes of grandeur were viewed with unspeakable delight by enlightened scientific observers, the ignorant and superst.i.tious were overpowered with horror and dismay. The description which a gentleman of South Carolina gave of the effect produced by this phenomenon upon his ignorant blacks will apply well to many hardly better informed white persons. "I was suddenly awakened," said he, "by the most distressing cries that ever fell upon my ears. Shrieks of horror and cries of mercy I could hear from most of the negroes of three plantations, amounting in all to about six or eight hundred. While earnestly listening for the cause, I heard a faint voice near the door calling my name: I arose, and, taking my sword, stood at the door. At this moment I heard the same voice still beseeching me to rise and saying, 'O! my G.o.d, the world is on fire!' I then opened the door, and it is difficult to say which excited me most, the awfulness of the scene or the distressed cries of the negroes. Upward of one hundred lay prostrate on the ground, some speechless, and some with the bitterest cries, but most with their hands raised, imploring G.o.d to save the world and them. The scene was truly awful, for never did rain fall much thicker than the meteors fell toward the earth; east, west, north, and south, it was the same."

Those harmless meteors, the _ignes fatui_, which hover above moist and fenny places in the night-time, emitting a glimmering light, have been regarded by the ignorant as malicious spirits endeavoring to deceive the bewildered traveler and lead him to destruction. The plaintive note of the mourning dove, the ticking noise of the little insect called the death-watch, the howling of a dog in the night-time, the meeting of a b.i.t.c.h with whelps, or a snake lying in the road, the breaking of a looking-gla.s.s, and even the falling of salt from the table, and the curling of a fiber of wick in a burning candle, together with many other equally harmless incidents, have been regarded with apprehensions of terror, being considered as unfailing signs of impending disasters or of approaching death.

Dr. d.i.c.k remarks, that in the Highlands of Scotland--and it should be borne in mind that the Scotch are, as a nation, better instructed, and more moral and religious in their habits, than any other people in Europe--the motions and appearances of the clouds were, not long ago, considered ominous of disastrous events. On the evening before new year's day, if a black cloud appeared in any part of the horizon, it was thought to prognosticate a plague, a famine, or the death of some great man in that part of the country over which it seemed to hang; and in order to ascertain the place threatened by the omen, the motions of the clouds were often watched through the whole night. In the same country, the inhabitants regard certain days as _unlucky_, or ominous of bad fortune. The day of the week on which the third of May falls is deemed unlucky throughout the year.

With a very slight change, a part of this description would apply well to our own country, even up to the present time. How many thousands of days are lost annually in the United States in consequence of superst.i.tious fears in relation to setting out upon a journey, entering upon a new pursuit of any kind, or even beginning to plant or plow on Friday, the unlucky day of the Americans. How many persons have had misfortunes attend them all their lives because they were born, or christened, or married on Friday! How many houses have been burned because they were begun, raised, or moved into on Friday! How many steamboats and vessels have been burned or wrecked because they were launched or sailed on Friday! And yet, strange as it may seem, this is the very day on which Columbus set sail on a voyage that resulted in the discovery of the New World.

Many people, and in some instances whole communities, always commence plowing, sowing, and reaping on Tuesday, though by this rule the most favorable weather for these purposes is frequently lost. Others, again, will not, on any account, perform certain kinds of labor on Friday. The age of the moon is also much attended to in many parts of the world.

Among the vulgar Highlanders, an opinion prevails, that if a house takes fire while the moon is in the decrease, the family will from that time decline in its circ.u.mstances and sink into poverty. In this country, equally unfounded and ridiculous opinions are entertained. Pa.s.sing by the more commonly received opinions that if swine are killed in the old of the moon, the pork will shrink in the pot; that seed sown at this time will be less likely to do well, etc., etc., I will mention one or two instances of opinions which, although equally well founded, are less commonly received, and which may therefore more forcibly impress the popular mind. A few years ago, I spent some months in a neighboring state, in a community where the belief was commonly entertained that shingles should not be laid nor stakes driven in the old of the moon, because the former would be more likely to warp, and the latter to be thrown by the frost. The same and kindred opinions are extensively held in various portions of the United States.

These are a few, and but a very few, of the superst.i.tious notions and vain fears by which the great majority of the human race, in every age and country, have been enslaved, as he who will take the pains to peruse Dr. d.i.c.k's admirable treatise on the improvement of society by the diffusion of knowledge can not fail to be convinced. That such absurd notions should ever have prevailed is a most grating and humiliating thought, when we consider the n.o.ble faculties with which man is endowed.

That they still prevail to a great extent, even in our own country, is a striking proof that as yet we are, as a people, but just emerging from the gloom of intellectual darkness. The prevalence of such opinions is to be regretted, not only on account of the groundless alarms they create, but chiefly on account of the false ideas they inspire with regard to the nature of the Supreme Ruler of the universe, and of his arrangements in the government of the world. He whose mind is enlightened with true science perceives throughout all nature the most striking evidences of benevolent design, and rejoices in the benignity of the Great Parent of the universe, discovering nothing in the arrangements of the Creator, in any department of his works, which has a direct tendency to produce pain to any intelligent or sensitive being.

The superst.i.tious man, on the contrary, contemplates the sky, the air, the waters, and the earth as filled with malicious beings, ever ready to haunt him with terror or to plot his destruction. The former contemplates the Deity directing the movements of the material world by fixed and invariable laws, which none but himself can counteract or suspend. The latter views these movements as continually liable to be controlled by capricious and malignant beings to gratify the most trivial pa.s.sions. How very different, of course, must be their conceptions and feelings respecting the attributes and government of the Supreme Being! While the one views him as the infinitely wise and benevolent Father, whose paternal care and goodness inspire confidence and affection, the other must regard him, in a certain degree, as a capricious being, and offer up his adorations under the influence of fear.

These and like notions have also an evident tendency to habituate the mind to false principles and processes of reasoning which unfit it for legitimate conclusions in its researches after truth. They manifestly chain down the understanding, and unfit it for the appreciation of those n.o.ble and enlarged views which revelation and modern science exhibit of the order, extent, and economy of the universe. It is lamentable to reflect that so many thousands of beings endowed with the faculty of reason, who can not by any means be persuaded of the motion of the earth, and the distances and magnitudes of the heavenly bodies, should swallow, without the least hesitation, opinions ten thousand times more improbable. Notwithstanding the mathematical certainty of the truth of the Copernican system of astronomy, I have never yet become extensively acquainted with any community in which I have not found many persons professing a respectable degree of intelligence, and even official members of orthodox churches, who entirely discredit its sublime teachings; and yet some of these very persons find little difficulty in believing that an old woman can transform herself into a hare, and wing her way through the air on a broomstick. What contracted notions such persons must have of the almightiness of the Deity, and of the infinite depth of meaning of the following and like pa.s.sages of Scripture: The heavens declare the glory of G.o.d, and the firmament showeth his handy work. Day unto day uttereth speech, and night unto night showeth knowledge.--_Ps._ xix., 1-2.

It has been already remarked, that the whole history of the world justifies the statement that ignorant and uncultivated mind is p.r.o.ne to sensuality and cruelty. Spain and Hungary were referred to in ill.u.s.tration. We are now prepared to remark, what is worse still, that where such superst.i.tious notions as we have been considering are held, even by persons who are somewhat educated, they almost invariably lead to the perpetration of deeds of cruelty and injustice. Many of the barbarities committed in pagan countries, both in their religious worship and their civil polity, and most of the cruelties inflicted on the victims of the Romish Inquisition, have flowed from this source.[33]

Nor are the annals of Great Britain and the United States deficient in examples of this kind. About the commencement of the last century, the belief in witchcraft, which was almost universal throughout Christendom, was held in both of these countries. The laws of England, which admitted its existence and punished it with death, were adopted by the Puritans of New England, and in less than twenty years from the founding of the colony, one individual was tried and executed for the supposed crime.

Half a century later the delusion broke out in Salem. A minister, whose daughter and niece were subject to convulsions accompanied by extraordinary symptoms, supposing they were bewitched, cast his suspicions on an Indian woman who lived in the house, and who was whipped until she confessed herself a witch; and the truth of the confession, although obtained in this way, was not doubted. During the same year more than fifty persons were terrified into the confession of witchcraft, twenty of whom were put to death. Neither age, s.e.x, nor station afforded any safeguard against a charge for this supposed crime.

Women and children not only were its victims, but magistrates were condemned, and a clergyman of the highest respectability was among the executed. So late as 1722 a woman was burned for witchcraft in Scotland, which was among the last executions in that country.

[33] In the Duchy of Lorraine, nine hundred females were delivered over to the flames for being _witches_, by one inquisitor alone. Under this accusation, it is reckoned that upward of _thirty thousand women_ have perished by the hands of the Inquisition.--Quoted by Dr. d.i.c.k from "_Inquisition Unmasked_."

It appears that these superst.i.tious notions, so far from being innocent and harmless speculations, lead to the most deplorable results; they ought, therefore, to be undermined and thoroughly eradicated by all persons who wish to promote the happiness and well-being of general society. This duty is especially inc.u.mbent upon parents and teachers, and can be effected only by rendering correct early education universal.

Ignorance of the laws and economy of nature is the one great source of these absurd opinions. They have not only no foundation in nature or experience, but are directly opposed to both. In proportion, then, as we advance in our researches into Nature's economy and laws, shall we perceive their futility and absurdity. As in other cases, take away the cause, and the effect will be removed.

_Education will dissipate all these evils._ It is true that an acquaintance with a number of dead languages, with Roman and Grecian antiquities, with the subtleties of metaphysics, with pagan mythology, and with politics and poetry, may coexist with these superst.i.tions, as was true in the case of the late Dr. Samuel Johnson, who believed in ghosts and in the _second sight_. However important in other respects these departments of an extensive and varied education may be, they do not form an effectual barrier against the admission of superst.i.tious opinions. In order to do this, the mind must be directed to the study of the material universe, to contemplate the various appearances it presents, and to mark well the uniform results of those invariable laws by which it is governed. In particular, the attention should be directed to those discoveries which have been made by philosophers in the different departments of nature and art during the last two centuries.

For this purpose, the study of natural history, as recording the various facts respecting the atmosphere, the waters, the earth, and animated beings, combined with the study of natural philosophy and astronomy, as explaining the causes of the phenomena of nature, will have a happy tendency to eradicate from the mind superst.i.tious and false notions, and at the same time will present to view objects of delightful contemplation. Let a person be once thoroughly convinced that nature is uniform in her operations, and governed by regular laws impressed by an all-wise and benevolent Being, and he will soon be inspired with confidence, and will not easily be alarmed at any occasional phenomena which at first sight might appear as exceptions to the general rule.

Let persons be taught, for example, that eclipses are occasioned merely by the shadow of one opaque body falling upon another; that they are the necessary result of the inclination of the moon's...o...b..t to that of the earth; that, if these orbits were in the same plane, there would be an eclipse of the sun and of the moon every month, the former occurring at the change, and the latter at the full of the moon; that the times when they do actually take place depend on the new or full moon happening at or near the points of intersection of the orbits of the earth and moon, and that other planets which have moons experience eclipses of a similar nature. Let them also be taught that the _comets_ are regular bodies belonging to our system, which finish their revolutions and appear and disappear in stated periods of time; that the northern lights, though seldom seen in southern climes, are frequent in the regions of the North, and supply the inhabitants with light in the absence of the sun, and have probably a relation to the magnetic and electric fluids; that the _ignes fatui_ are harmless lights, formed by the ignition of a certain species of gas produced in the soils above which they hover; and that the notes of the death-watch, so far from being presages of death, are ascertained to be the notes of _love_ and presages of hymeneal intercourse among these little insects.

Let rational information of this kind be imparted to people generally, and they will learn to contemplate nature with tranquillity and composure. A more beneficial effect than this will at the same time be produced, for those very objects which were formerly beheld with alarm will now be converted into sources of enjoyment, and be contemplated with emotions of delight.

To remove the groundless apprehensions which arise from the fear of invisible and incorporeal beings, let persons be instructed in the various optical illusions to which we are subject, arising from the intervention of fogs, and the indistinctness of vision in the night-time, which makes us frequently mistake a bush that is near us for a large tree at a distance, and let them be taught that under the influence of these illusions a timid imagination will transform the indistinct image of a cow or a horse into a terrific phantom of a monstrous size. Let them also be taught, by a selection of well-authenticated facts, the powerful influence of the imagination in creating ideal forms, especially when under the dominion of fear; the effects produced by the workings of conscience when hara.s.sed by guilt; let them be taught the effects produced by lively dreams, by strong doses of opium, by drunkenness, hysteric pa.s.sions, madness, and other disorders that affect the mind. Let the experiments of optics, and the striking phenomena produced by electricity, galvanism, magnetism, and the different gases, be exhibited to their view, together with details of the results which have been produced by various mechanical contrivances. In fine, let their attention be directed to the foolish, whimsical, and extravagant notions attributed to apparitions, and to their inconsistency with the wise and benevolent arrangements of the Governor of the universe.

There is no rational foundation for entertaining any doubts but that, could such instructions as I have suggested be universally given, the effect would be the banishment of superst.i.tions of the nature contemplated from among mankind; _for they have uniformly produced this effect on every mind which has been thus enlightened_. Where is the man to be found whose mind is enlightened by the doctrines and discoveries of modern science, and who yet remains the slave of superst.i.tious notions and vain fears? Of all the philosophers of America and Europe, is there one who is alarmed at an eclipse, at a comet, at an _ignis fatuus_, or at the notes of a death-watch? or who postpones his experiments on account of what is called an unlucky day? Who ever heard of a specter appearing to such a person, dragging him from bed at the dead hour of midnight, to wander through the forest, trembling with fear? Such beings appear only to the ignorant and illiterate, at least to those who are unacquainted with natural science, and we never hear of their appearing to any who did not previously believe in their existence. But should philosophers be freed from such terrific visions, if substantial knowledge has not the power of banishing them from the mind? Why should supernatural beings feel so shy in conversing with men of science? These would, indeed, be the fittest persons to whom they might impart their secrets, and communicate information respecting the invisible world; but it never falls to their lot to be favored with such visits. It may therefore be concluded that the diffusion of useful knowledge among mankind would infallibly dissipate those groundless fears which have banished much of happiness from the human family, and particularly among the lower orders of society.[34]

[34] Dr. d.i.c.k, to whom I have frequently referred, and whose writings I have freely consulted, expresses in a note a sentiment in which I fully concur. "It would be unfair," says he, "to infer, from any expression here used, that the author denies the possibility of supernatural visions and appearances. We are a.s.sured from the records of sacred history that beings of an order superior to the human race have 'at sundry times and in divers manners' made their appearance to men. But there is the most marked difference between vulgar apparitions and the celestial messengers to which the records of revelation refer. They appeared not to old women and clowns, but to patriarchs, prophets, and apostles. They appeared not to frighten the timid and to create unnecessary alarm, but to declare 'tidings of great joy.' They appeared not to reveal such paltry secrets as the place where a pot of gold or silver is concealed, or where a lost ring may be found, but to communicate intelligence worthy of a G.o.d to reveal, and of the utmost importance for man to receive. In these and many other respects, there is the most striking contrast between popular ghosts and the supernatural communications and appearances recorded in Scripture."

I might, perhaps, safely dismiss this subject, and proceed to the consideration of other topics; but, before doing so, it may be well to state that many of the views here presented, and all that come within the range of the subjects discussed by him, are fully sustained by Dr.

Lardner, whose popular lectures on science and art have been so well received both in Europe and America. His publishers justly remark, that "probably no public lecturer ever continued, for the same length of time, to collect around him so numerous audiences." The author himself states, in the preface to his Lectures,[35] that from November, 1841, when he commenced his public lectures in the lecture-room of Clinton Hall, in New York, to the close of the year 1844, when he concluded his public labors in this country, he "visited every considerable city and town of the Union, from Boston to New Orleans, and from New York to St.

Louis. Most of the princ.i.p.al cities were twice visited, and several courses were given in Boston, New York, and Philadelphia. Nor did the appet.i.te for this species of intellectual entertainment appear to flag by repet.i.tion."

[35] In two large volumes, published by Greeley and McElrath, New York.

I can not forbear making a few quotations from the preface to the work under consideration, which are creditable to the comparative intelligence of the American people, and show the avidity with which they seek instruction and useful knowledge. Dr. Lardner observes, that "it was usual on each evening to deliver from two to four of the essays which compose the contents of the present volumes, and the duration of the entertainment was from two to three hours. On every occasion the most profound interest was evinced on the part of the audience, and the most unremitting and silent attention was given. These a.s.semblies consisted of persons of both s.e.xes, of every age, from the elder cla.s.ses of pupils in the schools to their grandfathers and grandmothers.

Frequently the audiences amounted to twelve hundred, and sometimes, as at the Philadelphia Museum, they exceeded two thousand. Nor was the manifestation of this interest confined, as might be imagined, to the northern Atlantic cities, where education is known to be attended to, and where, as in New England, the diffusion of useful knowledge is regarded as a paramount duty of the state. The same crowded a.s.semblies were collected, for a long succession of nights, in the largest theaters of each of the southern and western cities; in the Charleston Theater; the Mobile Theater; the St. Charles Theater, New Orleans; the Vicksburg and Jackson Theaters, Mississippi; the St. Louis Theater, Missouri; and in the theaters of Cincinnati, Pittsburg, and other western and central cities.

"It can not be denied that such facts are symptomatic of a very remarkable condition of the public mind, more especially among a people who are admitted to be, more than any other nation, engrossed by money-getting and by the more material pursuits of life. The less pretension to eloquence and the attractive graces of oratory the lecturer can offer, the more surprising is the result, and the more creditable to the intelligence of the American people. It is certain that a similar intellectual entertainment, clogged, as it necessarily was, with a pecuniary condition of admission, would fail to attract an audience even in the most polished and enlightened cities of Europe."

While these statements are highly creditable to the American people, the lectures themselves contain paragraphs which show that the popular mind even in our own country is not sufficiently enlightened to eradicate the superst.i.tions just considered.

THE MOON AND THE WEATHER.--Dr. Lardner, in a lecture on the moon, in answer to the question, Does the moon influence the weather? says,[36]

It is a.s.serted, first, that at the epochs of new and full moon, and at the quarters, there is generally a change of weather; and, secondly, that the phases of the moon, or, in other words, the relative position of the moon and sun in regard to the earth, is the cause of these changes. Now these and kindred opinions are very extensively held in this country. But the doctor refers to meteorological tables, constructed in various countries after the most extensive and careful observation, and the result is that no correspondence exists between the condition of the weather and the phases of the moon. He hence, after a full examination, comes to the conclusion that "_the condition of the weather as to change, or in any other respect, has, as a matter of fact, no correspondence whatever with the lunar phases_."

[36] See Lectures on Science and Art, vol. i., p. 315.

In another lecture on the moon and the weather, the following decisive opinion is expressed: "From all that has been stated, it follows then, conclusively, that the popular notions concerning the influence of the lunar phases on the weather have no foundation in the theory, and no correspondence with observed facts."[37]

[37] Ibid., p. 419-420.

TIME FOR FELLING TIMBER.--In another lecture on lunar influences, Dr.

Lardner observes that "there is an opinion generally entertained that timber should be felled only during the decline of the moon; for if it be cut down during its increase, it will not be of a good or durable quality. This impression prevails in various countries. It is acted upon in England, and is made the ground of legislation in France. _The forest laws of the latter country interdict the cutting of timber during the increase of the moon._ In the extensive forests of Germany, the same opinion is entertained and acted upon, with the most undoubting confidence in its truth. Sauer, a superintendent of some of these districts, a.s.signs what he believes to be its physical cause. According to him, the increase of the moon causes the sap to ascend in the timber, and, on the other hand, the decrease of the moon causes it to descend.

If the timber, therefore, be cut during the decrease of the moon, it will be cut in a dry state, the sap having retired, and the wood, therefore, will be compact, solid, and durable. But if it be cut during the increase of the moon, it will be felled with the sap in it, and will therefore be more spongy, more easily attacked by worms, more difficult to season, and more readily split and warped by changes of temperature.

"Admitting for a moment the reality of this supposition concerning the motion of the sap, it would follow that the proper time for felling the timber would be _the new moon_, that being the epoch at which the descent of the sap would have been made, and the ascent not yet commenced. But can there be imagined, in the whole range of natural science, a physical relation more extraordinary and unaccountable than this supposed correspondence between the movement of the sap and the phases of the moon? a.s.suredly theory affords not the slightest countenance to such a supposition; but let us inquire as to the fact whether it be really the case that the quality of timber depends upon the state of the moon at the time it is felled.
