Three Edible Frogs. Three species were 

 used in the experiments in Pennsylvania, the 

 leopard, the green, and the common bullfrog. 

 The first is too small to be of much use for the 

 food-market, but is much sought after by 

 sportsmen as bait for certain game-fishes. The 

 green frog has the reputation of being the most

 hunted on account of its huge size, and the fact 

 that there is meat to be found on portions of its 

 back, and on the shoulders of the forelegs, as 

 well as on the full length of the hind legs. 



Partly because of the short time elapsing be- 

 tween the hatching of the tadpole and its devel- 

 opment into a frog, and partly because it 

 spawns early in April, the initial experiments 

 were with the leopard frog, but it soon became 

 manifest that it is not worth while to undertake 

 the propagation of this small species except for 

 the purpose of supplying anglers with bait. It 

 was found that there is apparently less likeli-

 gate the green, and the bullfrog, but the diffi- 

 culties accompanying the work are legion, and
