i'ROGS, TOAUS, AKD aALAMAN'DbRS 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 destro}' cutworms which other\\ise 

 would have damaged crops to the extent of $19.88." 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 theii' gardens.
