egg masses, as well as of white grubs and larvae of many other 

 injurious insects, and one can often see where they have dug small 

 cavities in the ground in search of this form of food. They are 

 regarded by the U. S. Biological Survey, which has made a special

study of their habits, as the most useful of our wild mammals 

 and therefore deserve protection rather than destruction by the 

 farmer. Both shrews and moles are burrowing mammals which 

 feed almost wholly upon insect life. True, the latter sometimes 

 destroy the seeds of corn and vegetables, but the good which they 

 do in destroying the eggs and larvae of injurious insects far out- 

 weighs the bad. Salamanders, or ground puppies, live beneath 

 logs and chunks and burrow into the surrounding region in search 

 of eggs and lame, while toads and snakes feed largely upon the 

 } y oung and mature of grasshoppers and locusts, yet all are usually 

 destroyed at sight by farmers or their sons. 



More than 100 species of birds are known to use as food either 

 the young or full grown individuals of many kinds of Orthoptera. 

 The U. S. Biological Survey at Washington and other authorities, 

 have made investigations of the stomachs of many species of 

 birds, and have found that the following are some of the more 

 common birds of our Eastern States which feed largely upon lo- 

 custs and grasshoppers.
