Another chart made from the examination of the stomachs of fifty 

 other animals would undoubtedly be quite different from this one. 

 However, this chart will give an idea based on the actual study of fifty 

 stomachs, and will be a beginning for some one who may, in the future, 

 give more time to the subject, and work it up more in detail. 



I think that it is safe to say that, when the ground is moist and the 

 earthworms are active, the animals feed freely upon them. When 

 the ground is dry, and early in the spring or late in the fall, when the 

 earthworms are not so active, grubs and beetles are eaten more freely 

 and constitute a greater proportion of the food than they otherwise 

 would. 



It is evident that the damage done to lawns, gardens and fields by 

 moles is due chiefly not to the food the animals eat, but rather to 

 their manner of securing it. Moles make many burrows or runways 

 two or three inches under the ground by digging and then lifting up 

 the soil with their shoulders. In making these runways, the little ani- 

 mals root up and destroy many plants, and especially the grass that 

 usually grows on the runways in lawns and pastures. Mice frequently 

 follow along in the runways made by the moles, and do considerable 

 damage to bulbs, roots, and grains.
