I 



DID you ever see two friendly dogs meet when 

 one tried to tell the other of something he 

 had discovered, when they touched noses, stood 

 for a moment in strange, silent parley, then wagged 

 their tails with mutual understanding and hurried 

 off together on a canine junket? 



That was the little comedy which first drew my 

 attention to the matter of animal communication, 

 many years ago, and set my feet in the unblazed 

 trail we are now to follow. And a very woodsy 

 trail you shall find it, dim and solitary, with plenty 

 of "blind" spots where one may easily go astray, 

 and without any promise of what waits at the 

 other end of it.
