Voices of a New England Marsh

three hundred are calling at once, however, the din is rather overpow- 

 ering and at times also annoying, for it more or less completely drowns 

 all other sounds. 



The notes of the leopard frog have been not inaptly compared to the 

 sound of snoring. In earlv April they are heard oftenest during the 



SORA IDnc-lKilf natural size) 



warmer hours of the day, but after the middle of the month these frogs 

 snore chiefly — as seems, indeed, appropriate — by night. When the 

 weather is calm and the voices of huiuireds of individuals are coming 

 from far and near, they fill the air with sound that never ceases for an 

 instant, although ever fluctuating in volume like the rote of ilistant surf. 

 The pickerel frog is also very conunon in our nieailows. Mr. Sidney 

 F. I)(iir()ii tells me that it begins croaking rather later in the season 

 than the leopard troLj ami that its notes resemble those of that species.
