Frogs are very common, especially in Lower Louisiana, notwithstanding the great number of snakes that destroy them. There are some that grow very large, sometimes above a foot and a half long, and astonish strangers at first by their croaking especially if they are in a hollow tree.

The Crocodile is very common in the river Missisippi. Although this amphibious animal be almost as well known as those I have just mentioned, I cannot however omit taking some notice of it. Without troubling the reader with a description of it, which he will meet with every where, I shall observe that it shuns the banks of the river frequented by men. It lays its eggs in the months of May, when the sun is already hot in that country, and it deposits them in the most concealed place it can find among grass exposed to the heats of the south. The eggs are about the size of those of a goose, but longer in proportion. Upon breaking them you will find hardly any thing but white, the yolk being about the size of that of a young hen. I never saw any that were new hatched. The smallest I ever met with, which I concluded to be about three months old, was as long as a middle-sized eel, and an inch and a half thick. I have killed one nineteen feet long, and three feet and a half in its greatest breadth. A friend of mine killed one twenty-two feet long, and the legs of both these, which on land seemed to move with great difficulty, were not above a foot in length. But however sluggish they be on land, in the water they move with great agility.

This animal has his body always covered with slime, which is the case with all fishes that live in muddy waters. When he comes on shore his track is covered with that slime, as his belly trails on the ground, and this renders the earth very slippery in that part, especially as he returns by the same path to the water. He never hunts the fish upon which he subsists; but places himself in ambuscade, and catches them as they pass. For that purpose he digs a hole in the bank of the river, below the surface of the water, where the current is strong, having a small entrance, but large enough within to turn himself round in. The fish, which are fatigued with the strong current, are glad to get into the smooth water in that corner, and there they are immediately seized by the crocodile.

I shall not contradict the accounts of venerable antiquity about the crocodiles of the Nile, who fall upon men and devour them; who cross the roads, and make a slippery path upon them to trip passengers, and make them slide into the river; who counterfeit the voice of an infant, to draw children into their snares; neither shall I contradict the travellers who have confirmed those stories from mere hearsays. But as I profess to speak the truth, and to advance nothing but what I am certain of from my own knowledge, I may safely affirm that the crocodiles of Louisiana are doubtless of another species than those of other countries. In fact, I never heard them imitate the cries of an infant, nor is it at all probable that they can counterfeit them. Their voice is as strong as that of a bull. It is true they attack men in the water, but never on land, where they are not at all formidable. Besides, there are nations that in great part subsist upon this animal, which is hunted out by the fathers and mothers, and killed by the children. What can we then believe of those stories that have been told us of the crocodile? I myself killed all that ever I met of them; and they are so much the less to be dreaded, in that they can neither run nor rise up against a man. In the water indeed, which is their favourite element, they are dangerous; but in that case it is easy to guard against them.

The largest of all the reptiles of Louisiana, is the Rattle-Snake: some of them have been seen fifteen inches thick, and long in proportion; but this species is naturally shorter in proportion to their thickness than the other kinds of serpents. This serpent gets its name from several hollow knots at its tail, very thin and dry, which make a rattling noise. These knots, though inserted into each other, are yet quite detached, and only the first of them is fastened to the skin. The number of the knots, it is said, marks the age of the serpent, and I am much inclined to believe it; for as I have killed a great number of them, I always observed, that the longer and thicker the serpent was, it had the more knots. Its skin is almost black; but the lower part of its belly is striped black and white.

As soon as it hears or sees a man, it rouses itself by shaking its tail, which makes a rattling noise that may be heard at several paces distance, and gives warning to the traveller to be upon his guard. It is much to be dreaded when it coils itself up in a spiral line, for then it may easily dart upon a man. It shuns the habitations of men, and by a singular providence, wherever it retires to, there the herb which cures its bite, is likewise to be found.

There are several other kinds of serpents to be seen here, some of which resemble those of France, and attempt to slip into the hen-houses to devour the eggs and new-hatched chickens. Others are green, about two feet long, and not thicker than a goose-quill; they frequent the meadows, and may be seen running over the spires of grass, such is their lightness and nimbleness.

Vipers are very rare in Lower Louisiana, as that reptile loves stoney grounds. In the highlands they are now-and-then to met with, and there they quite resemble ours.
