260 REPTILES OF THE WORLD 



excites but one idea, a determination to eradicate the 

 "plague" of reptiles. In reality, the presence of the 

 snakes is significant. They instinctively congregate in 

 places where rodents are becoming numerous — the wild 

 mice and rats, and the ground squirrels, each capable 

 of causing the farmer much trouble and loss. Traps are 

 of little avail when pitted against the sagacity of the

 traps ; meanwhile, they continue to slaughter every snake

 overrides all desire for argument. Frequent times, 

 when the writer has gone to some pains to explain the 

 subject to an inveterate snake-killer, he has elicited noth-

 he stopped on a farm where the rats were becoming an 

 alarming menace to the owner's scanty profits. Several 

 species of the larger, harmless snakes were common, 

 entering the barns, where they coiled on the girders. 

 The sight of a snake never failed to produce a commo-

 Poisonous snakes were not found in the neighborhood. 

 Knowing the harmless species to be of economic value 

 to his host, besides in every way inoffensive, the writer 

 ventured to expostulate. His remarks excited caustic 

 replies. Nettled at the result, he suggested eachjsnake 

 killed be brought to him for dissection. This arrange- 

 ment elicited an interesting fact: — Nearly every reptile
