devoured were of the black or blackish-brown ground varieties, such, 

 for instance, as Harpalus -pennsylvanicus. 



By referring to a chart which I have prepared, this j)aper becomes 

 much more intelligible. It gives the dates of capture of the speci- 

 mens, the kind and per cent., in quantity, as nearly as it could be 

 estimated, of the various foods found in each stomach. 



Earthworms constitute the most common article of food. Thirty- 

 eight out of the fifty specimens had eaten earthworms, and "six had 

 eaten nothing else. 



Earthworms constitute 42.20 per cent, of the entire food. Twenty- 

 seven of the animals had eaten ground-beetles, which make up 22.7 

 per cent, of the entire food supply. Thirty-four stomachs contained 

 grubs and larvse of various kinds, which constituted 22.8 per cent, of 

 the stomach contents. Four stomachs contained from 5 to 20 per cent, 

 each of insect eggs, apparently those of grasshoppers. 



One stomach contained twenty and another thirty ants, making in 

 each case about 20 per cent, of the food. 



Three stomachs contained myriopods ( Geophilus ) . One mole had 

 eaten seven specimens and another eleven, making 100 per cent, of 

 the food in both cases, as there was no trace of anything else. 



Vegetable food was represented by 3.7 per cent. Four of the ani- 

 mals had eaten kernels of corn, which made up from 10 to 65 per cent, 

 of the food. These animals were taken in January and October. The 

 animals were caught near fields where kernels of corn had perhaps 

 been trampled into the earth and had become softened. Otherwise I 

 do not see how the fine teeth of the mole could have chewed up the 

 kernels. Two of these specimens, one taken January 18, 1894, and 

 one October 6, 1894, had the stomachs well filled with corn. There 

 was little doubt about the identification of the material, as the profes- 

 sors in the department of botany at the University assisted in its de- 

 termination. 



Seeds of grass, hemp and some long seeds that resembled small rye 

 grains represented 20 per cent, of the food of a specimen taken Jan- 

 uary 8, 1894. 



Four stomachs harbored from three to seven white parasitic worms 

 about three-quarters of an inch long. 



One animal, taken November 9, 1894, had an enlarged and diseased 

 stomach. There were a number of warty-like blisters on the inside 

 of the stomach as large as wheat grains. When opened, they con- 

 tained a black substance that resembled the earth mud frequently 

 found in the stomachs of the animals that had been feeding upon earth- 

 worms.
