DELAWARE COUNTY FROGS. 1 7 



They seemed not to swim off into the middle of the pond. 

 They appeared rather to sink jout of sight at the places where 

 they had been sitting. I finally found that each frog had a 

 retreat of his own — a narrow, horizontal gallery running 

 back beneath an overhanging bank ; a burrow, in fact, after 

 the pattern of a muskrat den. One of these holes was found 

 to be more than three feet deep — how much more I could not 

 discover. These evidently were old residents, and each had 

 built his house. 



The above observation about the bull frog's habits I had 

 supposed to be new. But within two months after it was 

 made I read, in Mary E. Bradford's curious little book, " Up 

 and Down the Brooks," an account of a small California lad 

 who volunteered to the lady the information " that frogs have 

 regular sleeping places in holes on the sides of pools." "You 

 can come to this pool at night and see them," said he ; " some 

 go into the grass, .and the same frogs go in the same holes." 



This bull frog died of a blow on the head. His stomach, 

 on investigation, showed a number of caterpillars, three or 

 four grasshoppers and a field mouse. 



The liking of frogs for mice has been commercialized by a 

 frog farmer in New England, who regularly feeds his drove, 

 or flock — what shall we sa}' ? — with field mice. He sits in a 

 chair and holds the mice by the tails, while the frogs come 

 gravely up and swallow them. 



The Gkekx Frog, (RcDia clamata, Daudin). 

 This is next to the bull frog in size. It gets to be three 

 inches long. It is brownish green on the back, bright green 

 about the head. On the back there are little, black specks. 

 I have only young specimens to show. 



It is a common frog along meadow rills and in ponds. I 



do not think it is in the practice of burrowing in the bank 



like the bull frog. It generally swims away to the deepest 



,part of the pond when disturbed. It is capable of making a 



noise of some loudness.
