That he is susceptible of being trained, there can be no question. Man is not always viewed by him as an inveterate enemy, nor does he always dive headlong into the pool when his presence is near. He has been known to cultivate man’s acquaintance, and to live on friendly terms with him. Some three years ago a tiny frog was taken from a swamp by a friend and placed in a small stream of spring water that passed close to the house where the writer was summering. A dozen times a day the little frog was dipped up by the hand from the bottom of the stream, and forced to endure down the head and back the tenderest caresses. A few insects were then offered as food in conciliation for the liberty taken, which the little frog was only induced to accept after a great deal of persuasion, when he was carefully put back into his watery bath. In the space of a week, the frog had become so attached to his friend, that he would leap into his outstretched hand and take his food without the least distrust or fear. Even the voice of the master was recognized by the frog, and, when heard in the distance, was the signal for the strangest behavior. Froggie would leap out of the water upon a bare stretch of earth, peer off in the direction whence the sound came, and there await his master’s arrival with restless anxiety. The strongest bond of friendship seemed to unite the two. Not only was the frog able to recognize the voice of his friend, but he knew him in person as well. Repeated efforts were made by the writer to gain the attention and good-will of the frog, but all his advances were received with the utmost indifference. While the species which I have just described represents the aquatic Ranidæ, the Wood-frog, its near kin, represents a branch of the family which prefers dry situations, except in breeding times, when the eggs must be deposited in water. The Wood-frog is somewhat smaller than the Bull-frog, and is clad in olive-green and brown colors, which are in perfect keeping with the coloration of dead leaves and dry twigs. There is a large black patch on the side of the head around the big ear-drum, which seems still further to distinguish him from his cousin. He is a very shy and suspicious creature, and makes a prodigious jump at the first intimation of danger, his leaps being so enormous that it is very difficult to capture him. When upon the ground, he can hardly be discerned from the dry vegetation around. By hiding in damp moss or in decayed logs, and in little hollows in the ground, he is enabled to maintain the moisture of his skin. He avoids the sunshine, and keeps close to the earth.
