II 



HPHE simplest or most obvious method of 

 1 animal communication is by inarticulate 

 cries, expressive of hunger, loneliness, anger, pleas- 

 ure, and other primal needs or emotions. The 

 wild creatures are mostly silent, and so is the 

 bulk of their "talk," I think; but they frequently 

 raise their voice in the morning or evening twilight, 

 and by observing them attentively at such a time 

 you may measure the effect of their so-called 

 language. Thus, you see plainly that to one call 

 the animal cocks his ear and gives answer; at 

 another call he becomes wildly excited; a third 

 passes over him without visible result; a fourth 

 sets his feet in motion toward the sound or else
