FROGS, TOADS, AND SALAMANDERS 245 



The toads eat only living, moving insects, centipeds, sow 

 bugs, etc. They destroy great numbers of noxious insects 

 in gardens and fields. Professor Kirkland found by 

 examining the stomachs of many toads that "a single toad 

 in one season might destroy cutworms which otherwise 

 would have damaged crops to the extent of 119.88." The 

 toad is of conspicuous service to all agriculturists, but es- 

 pecially so to gardeners, who should try to collect toads and 

 keep them in their gardens.
