them alive. As soon as the poor creatures 
saw the boat approaching they made every 
effort to reach the shore; they had little 
chance, however, of escape, for deer, with 
their small feet, swim but slowly. The 
boat was quickly gaining; one of the 
animals was about fifteen feet in 
front of its fellow, and only thirty 
yards from the shore, the boat a 
few yards only from the hindmost 
one, when suddenly there was a 
shout on board, ‘the front one has 
turned round!’ It was true enough ; 
it had turned deliberately, and going 
quickly towards its companion, began 
helping it along by swimming and 
pushing at its side. I am not 
ashamed to admit that I turned 
away at this point. I found out 
afterwards that they became quite 
tame and had a good home in the 
park at Seattle.”

of the world. Those most nearly 
related to: the Common Bull-}'rog 
all belong to the family Ranide@, and 
if 1s In this group, too, that we meet 
with the Common Frog of Europe 
(R. temporaria), as well as that 
other celebrated Huropean species, 
the Edible Frog (R. esculenta). 
Some frogs are of great size, but in 
this respect, so far as the writer is 
aware, none exceed the bull-frog of 
North America (Rana catesbiana). 
One in the collections of the United 
States National Museum has a total 
length of nearly two feet. The 
one in the accompanying photo- 
graph measured considerably over 
a foot. Young frogs pass through 
certain well-known stages before 
assuming the adult form. These 
stages are undergone in the water, 
and include the passage from the 
egg to the young frog, including the tad- 
pole stage, the development of the lmbs, 
and the loss of tail and other changes. 
Bull-frogs spend most of their time in the 
water. They feed principally on worms, 
insects, crayfish and other forms.”
