 pond's edge, or of having heard a reptile croak-

Our walks wUl become more and more interest-

 not confining our observations to birds and mam-

 equally distinctive classes of animals mentioned 

 above. The batrachians, in the northeastern 

 part of our country, include the salamanders 

 and newts, the frogs and toads, while as reptiles

Lizards are creatures of the tropics and only
