THE FIFTH DAY.

CREEPING THINGS.

"_His hand hath formed the crooked serpent._"--JOB xxvi. 13.

"_The Lord thy G.o.d ... who led thee through that great and terrible wilderness, wherein were fiery serpents, and scorpions._"--DEUTERONOMY viii. 15.

"_The wolf and the lamb shall feed together, and the lion shall eat straw like the bullock: and dust shall be the serpent's meat. They shall not hurt nor destroy in all My holy mountain, saith the Lord._"--ISAIAH lxv. 25.

The "_creeping things_" which G.o.d caused the earth to bring forth on the Fifth Day are so unlike each other in many respects that we might at first sight wonder that they should have been grouped together; but the more we study Reptiles--so called from the Latin word _reptilis_, creeping--the more we see that there are many things which this great family of vertebrate animals have in common.

There are four chief divisions of the Reptile family--Tortoises and Turtles, Crocodiles, Lizards, and Snakes.

Most reptiles have a tail and two pairs of limbs, but, as you know, Snakes are dest.i.tute of limbs, and seem to move along by a motion from inside, so that they have been said to walk on their ribs. Serpents are covered with h.o.r.n.y scales; Crocodiles and Tortoises have a bony covering.

The Tortoise--so called from its twisted feet, or its crooked way of walking--has, as you know, an upper and an under sh.e.l.l which covers its body like a coat of mail, protecting it from every enemy except man. This strong sh.e.l.l is, like that of the snail, a house for the tortoise to live in; but this house is formed by arched bones, and is part of the creature itself. The four feet of the tortoise or turtle, and a curious mouth rather like the beak of a bird--without teeth, but with jaws hard enough to make a bite from it very painful--and a little scaly tail; these are the only parts of the animal not covered by the shields of its bony sh.e.l.ls.

The Lizard has both limbs and teeth, but no sh.e.l.l. Lizards are wonderfully active, darting away at the least alarm, so that it is not easy to catch them.

We may think of the Crocodile of the African, and the Alligator of the North American rivers, as enormous lizards; though they are now placed in a cla.s.s by themselves, on account of their h.o.r.n.y covering, which is so strong that it is almost impossible to pierce through it, and so smooth that a bullet will glance off from it. Serpents have neither sh.e.l.l nor limbs.

Their vertebrae, as you will see, if you look at any skeleton of a snake in the Museum, fit very beautifully one into the other; and owing to this they are able to glide swiftly along the ground, to coil their shining length round trees, and to dart their heads in every direction.

In one respect Tortoises, Lizards, and Serpents are alike--they all lay eggs, only the sh.e.l.l is not made of lime and earth, but is soft like leather. They are also cold-blooded animals, like fish. Of tortoises, some live on land, some in marshy places, some in rivers; turtles live in the sea, their lungs being so made as to enable them to remain under water without breathing.

The common tortoise, often kept in gardens, is found in the south of Europe, and is generally not more than nine inches long. Its upper shield is exceedingly strong. My brothers and sisters and I used often to stand upon the back of a pet tortoise which lived in our garden; it did not seem to feel our weight, but I remember finding it no easy matter to keep my feet together upon its smooth back, and none of us could perform this feat unless the tortoise was pleased to stand still while we balanced ourselves upon him. I can, in imagination, see this little tortoise of ours now, not larger than a crab such as you see at the fishmonger's, with its short legs and feet, and its little tail, all covered with scales, sticking out between its upper and under sh.e.l.ls. How we used to laugh, when we saw him draw in his head and feet under the shelter of the sh.e.l.l: the only sign he gave of being annoyed at all our pranks! We were told that our tortoise might not die for a hundred years, and I have heard that some have been known to live twice that time; it is a slow sort of life, but we must not forget that, in the poem about the Hare and the Tortoise, it was "slow and steady" that won the race.

I cannot remember that we ever gave our tortoise anything to eat; it must have catered for itself in the garden where it was so fond of burrowing and hiding away, that we had many a hunt for it when it was supposed to be lost. Mr. Wood speaks of a small one which he used to feed with bread and milk. He kept it, not in a garden, but in his own room, where its favourite place was the rug: for it enjoyed the heat so much, that it made many attempts, with its short legs and heavy sh.e.l.l, to climb over the fender in order to get nearer to the fire. I don't remember that our tortoise ever made any noise; but this one, shortly before it died, went about mewing like a young kitten. Far from living to be a hundred, Mr. Wood's pet died so soon that he had no opportunity of seeing whether it would in time get to know him; but a story is told of a tortoise who did take a fancy to one person, and, though he would attend to no one else, would come creeping along at her call, and tap the boot of his favourite with his beak, in token, we may suppose, of his regard. One lady, who had a long-standing acquaintance with a tortoise, having fed him for thirty years, said he would come to her, and to no one else; which looked rather like "cupboard love," you will say.

You may have often admired the tortoise-sh.e.l.l of which combs are made, with its beautiful wavy lines and markings; it is taken from the outside of the sh.e.l.l of the turtle or sea-tortoise, which is caught not only for the sake of its sh.e.l.l, but because its flesh is so good to eat. You may perhaps have seen, as I have, a small turtle at the door of a shop, and wondered where it came from, and what brought it there. You may be quite sure that it has come a long way, and that the poor creature is soon to be made into soup.

Very awkward it looks, poor thing; for its proper home is in the water, and not on the hard pavement; its feet are rather like fins, so that it may be able to make its way rapidly through the water, and it only comes ash.o.r.e to make its nest in the sand, where it scoops out a great hole with its paddle-like feet, and then covering its eggs over safely, leaves them for the sun to hatch.

I have heard that as many as two hundred eggs have been found in one of these sand-nests; but not all laid by one turtle; for those who hunt for the eggs have watched a crowd of animals come ash.o.r.e, and have seen one of them dig a deep pit with its broad paws, lay its eggs, and cover them over; then another has done the same, until there have been several layers of eggs: such a nest is a lucky _find_; for turtle eggs are said to be delicious food, though some I tasted were very "strong" and nasty.

[Ill.u.s.tration: TURTLE.]

The turtles common in Jamaica, and other islands of the West and East Indies, are great creatures five or six feet long, but they are not difficult to capture, for when once they have been turned over on their backs, the sh.e.l.l is so heavy that they cannot, owing to the shortness of their legs, turn themselves back again, but lie helpless on the sand.

Of Lizards, the second division of the Reptile group, I doubt if you have seen any, except in the Reptile-house at the "Zoo"; for although there are two kinds of these active little creatures in our country, they do not often court our society. The common lizard, about six inches long, with very bright eyes, has a tail which is so brittle, that if you were to catch hold of it, it would break right off, and its late owner would dart away to its hiding-place, leaving the old tail in your hand; itself growing a new one.

The Sand-lizard, also found in England, is about twice the length of the common lizard: it lives on sandy heaths, and like the turtle, lays its eggs in the sand, to be hatched by the sun. But neither of our lizards is so pretty as the little green one so common in the warmer countries of Europe.

It may be seen on walls, or by the wayside, basking in the sunshine, and now and then darting at a fly. The whole species are, like the b.u.t.terflies, summer creatures, and hide themselves safely underground before winter comes.

In the Reptile-house of the Zoological Gardens, I have often stood to look at the largest kind of lizard; for the Crocodile, that huge animal with its green glaring eyes, and its armour made of bony plates with sharp ridges, is but an overgrown lizard. If you wish to form some idea of what it is most like, you can look at one of the beautiful little newts which live in some pond or ditch near you, and fancy it magnified many, many times, and then you will not have a bad notion of the crocodile, the lizard of Africa, or of the Cayman or Alligator, the great lizard of the New World.

[Ill.u.s.tration: CROCODILE.]

The word crocodile means a creature which dislikes saffron; so it would be of no use, I suppose, for us to offer that lazy-looking animal floating in his tank, looking as lifeless as the trunk of a tree, with his nose and a little ridge of his mail-clad back alone appearing above the water, a saffron bun--to say nothing of his being a creature whose appearance does not seem to invite us to come to close quarters, or to hold any communication with him. But we have little idea of what these enormous reptiles are really like, when we see them so far away from their native haunts. It is thought by some that the "_leviathan_," spoken of in the book of Job, whose "teeth are terrible round about," is the crocodile; for its mouth is larger than that of any other animal, and is armed with very sharp teeth. Dr. Smith tells [Footnote: "Nile," _Dictionary of the Bible_, p. 621.] us that crocodiles were once so plentiful in the East, that the great river of Egypt swarmed with them, and the Egyptians, who made almost everything into a G.o.d, worshipped them and made mummies of them, as they did of birds, cats, and snakes.

I have often thought that when the mother of Moses long ago laid that child who was "fair to G.o.d" in his bulrush cradle among the reeds by the river's bank, her heart must almost have failed her as she remembered the terrible crocodiles; but she had faith in G.o.d, and He suffered no wild beast to molest that little ark. The crocodile feeds upon fish, and any animals which he can catch, when they come to the banks of the Nile and other African rivers to drink. Though it is clumsy in its movements on land, it makes its way swiftly through the water by means of its tail; sometimes it opens its terrible jaws, gives a great yawn, and then shuts them again with a sound which is heard far away. Mr. Arnot, a missionary in the heart of Africa, tells us that the crocodiles in the great river Zambesi drag the game which they catch under water, and so drown them, and then hide them under the river's banks. He says, "I used to watch these animals come up with perhaps a quarter of an antelope, and by firing at their heads I compelled them to drop their supper, Which my men picked up from their boats." The crocodiles' eggs are about the size of goose-eggs, and are said to be good to eat.

Herodotus, the "Father of History," tells a curious story about the crocodile and the Nile bird. He says, "When the crocodile takes his food in the Nile, the interior of its mouth is always covered with flies. All birds with one exception flee from the crocodile: but this one bird, the Nile bird, far from avoiding it, flies towards the reptile with the greatest eagerness, and renders it a very essential service. Every time the crocodile goes on sh.o.r.e to sleep, and at the moment when it lies extended, with open jaws, the Nile bird enters the mouth of the terrible animal and delivers it from the flies that it finds there. The crocodile shows its recognition of the service by never harming the bird."

I have heard that the flies which molest the crocodile are gnats, and their devourer a kind of plover.

Near Karachi, in India, there is a swamp caused by hot springs, which is inhabited by crocodiles. There are over two hundred in the tank, which has been walled in, as they are considered sacred creatures. Buffaloes stand in the water unharmed, but any other animal which came within reach would be instantly devoured. A rash young Englishman once made the tour of this tank, alive with crocodiles, by walking on their h.o.r.n.y backs!

Alligator is only the Spanish name for all lizards, so called in allusion to their having legs like arms. The great American lizard, known by this name, is not so large as the crocodile; it loves heat, and will bury itself in the mud in cold weather. It feeds mostly upon fish, and will drive them before it in a shoal, until they have got into some creek or narrow bend of the river, and then stun them by blows of its great tail. Mr. Waterton, who knew the South American rivers so well, tells us that he once came upon what he thought a pretty sight--a number of young alligators, about a foot long, playing about on the sand like so many rabbits. He also tells a story, which might have had a sad ending, saying [Footnote: _Life of Charles Waterton_, p.56] that when he was anxious to secure an alligator, which he much wished to stuff, with its tough skin uninjured, he would not allow his men to shoot at him, but actually jumped upon his h.o.r.n.y back and rode him along the sandy river-bank until the poor creature was tired out, and the daring rider secured his prize. I daresay yon would like to see the picture which one of his friends made of him, riding upon his dangerous steed.

We may form some idea of this naturalist's feat from what he tells us in another part of his book about his "wanderings." "One Sunday afternoon,"

he says, "when a good many people were standing about on the banks of the Orinoco, never dreaming of danger, a great Cayman came suddenly out of the river, seized a man, and carried him off beneath the water, so that he was seen no more."

How sad it would have been had Waterton shared a similar fate, in his effort to get the alligator's skin! Life is a precious gift from G.o.d, and no one has a right to risk his life in a rash foolhardiness, which is very different from the true courage which does not shrink from facing danger if the life of one more helpless than himself is in peril.

But while we know that no one has a right to give up his life unless at G.o.d's desire, and that it is wicked in His sight for anyone to risk losing his life unless at G.o.d's command, we must not forget that there is no risk for those who count not their lives dear to them for Christ's sake. He spoke some solemn words about "loving" and "hating" life, which His servants should ever remember.

You will be interested to know that the alligators' eggs are laid in a nest made of gra.s.s on the banks of a stream, and that they often travel for miles across forest or prairie from one stream to another. The nest is raised higher and higher by a fresh layer of gra.s.s, cut with the great water-lizard's sharp teeth, every time more eggs are laid, until it is as high as a c.o.c.k of hay. The eggs take a month to hatch; but as soon as the young alligators are out of the sh.e.l.l, they are quite able to run about and get their own living.

A gentleman who was looking after some building in a lonely part of South America,

"Where on the mighty river banks, La Platte and Amazon, The Cayman, like an old tree trunk, Lies basking in the sun."

caught a baby-alligator, and made it so tame that it would follow him about the house like a dog.

It must have been a strange sight to see this little creature, born in a rushy swamp, scrambling upstairs after his master; but stranger still to see him lying on the rug before the fire, with his head resting upon the cat, of whom he had become so fond that he was restless and uncomfortable when she was not near him.

He was fed on raw meat and milk, and was shut up in cold weather, like the tame swallow, in a box lined with wool; but, alas! one frosty night the poor little pet was forgotten, and next morning found him dead, killed by the cold. How often we find that the stories of pet animals, especially wild ones which have been made unnaturally tame, have had a sad ending!

The Blind-worm, so called from its small eyes--and yet these tiny eyes are brighter than some larger ones--is a kind of lizard without legs, and is, on that account, sometimes included in the Snake-family. We may come upon it in hot weather, among the furze bushes upon the common, or the stones of some old ruin. It feeds upon a little grey slug, and is like the common lizard in being so brittle that you can hardly take hold of it without breaking it.

There is one more lizard which I have seen next door to the crocodile tank at the Zoo: a very curious little animal, almost of the same colour as the stick along which it walks, so slowly and silently that you may stand and watch it for some time without being sure that it is moving at all; though its eyes, which can move in different directions at the same moment, and its long thin tongue, so clever at catching the insects on which it feeds, are constantly in motion; but for its eyes and tongue, the Chameleon looks as if it were as dead as the withered branch to which it clings.

The name of this lizard means "Ground-lion," but it is very unlike the king of beasts both in appearance and disposition. The chameleon is found in Spain, in Sicily, and in Syria; its home is in the branches of trees. Many stories used to be told of the way in which it would change colour, not exactly by blushing like a human creature, but by becoming green, yellow, and even black when angry or calm, or when in sunshine or shade; but naturalists who have kept a careful watch upon it do not believe that all that has been said about this is true. There seems to be no doubt, however, that it changes its colour according to its surroundings--a means of protection given to a creature otherwise very defenceless.

[Ill.u.s.tration: "A lizard's body, lean and long, A fish's head, a serpent's tongue."]

Serpents--so called from a word which means that which _creeps_--are constantly used in the Bible as emblems of deceit and treachery. The words, "More subtle than any beast of the field," may well come to our minds as we watch a serpent, with its limbless body, winding along with that soft, gliding motion to which we have given the name "snake-like."

In the serpent's eyes, too, though they are often so beautiful that we cannot but admire them, there is some of this same dangerous subtlety--an untrust--worthiness which makes us shrink from looking at them.

There are many varieties of this large family; some, like the rattlesnake, cannot climb or swim, but crawl along the ground, the terror of unwary travellers who may tread upon them in the dim forest-paths; others are Water-snakes; some, like the Boa and Python, are dreaded, although not venomous, because, of their enormous strength, and power of crushing their victims in their close embrace; others, like the Cobra, for their deadly bite; while many--we might almost say most--snakes are quite harmless, for it has been reckoned that not more than one in ten is venomous; and none but the giants of this family are dangerous, except for their poisoned bite. The skin of serpents is covered with what are called false scales, which do not overlap each other like those of the fishes, but only seem to do so; and these scales are said to help them to move along rapidly. Most of them are beautifully marked and spotted, and some shine like gold in the sun, while others have pale, soft tints; but these lovely colours fade in death, just as those of fish do; so that a snake in all its glittering beauty can only be seen when alive. They often change their skins, creeping out of the old and appearing ready-dressed in the new. A traveller along the banks of the Nile has often found these cast-off skins in the fields; they are always turned inside out, for the old skin, which is very soft, folds back as the snake slips out of it.
