178 Life and Immortality. 
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 dis- 
trust 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 Ranidz, 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 intima- 
tion 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 hol- 
lows in the ground, he is enabled to maintain the moisture 
of his skin. He avoids the sunshine, and keeps close to 
the earth. 
Another curious Rana is the Tree-frog. He is smaller 
than any of his cousins, and may be known by his bright
