former channels. There are two large tributary streams, Bear 

 Creek and Cuschwahr Creek, in the region studied, and several 

 smaller ones; like the river, they have considerable current 

 and little vegetation. The only large body of quiet water is 

 JMeesic Lake, in the northern part of the area, which is about 

 a mile and a half long and a mile wide and is margined on 

 three sides by spruce swamps and on the other by a ridge 

 clothed with a forest of hardwoods. The small bodies of 

 quiet water are beaver ponds, varying in size and depth, and 

 small, stagnant ox-bow ponds cut off from the river, which 

 are filled witli water plants. 



The habitats frequented by the reptiles and amphibians, as 

 revealed by our studies, are shown in the following table.
