THE PSYCHIC DEVELOPMENT OP YOUNG ANIMALS. 47 



In gnawing their own bone, in growling and acting on the defensive generally there is 

 considerable admuire over the 59th day. 



They are allowed into the large yard to-day tor the iirst time. Tliey have seen this 

 yard from the kennel and from their wire fence run in the middle of it. They mingle with 

 the older dogs and act very much like them. They tr}' to suck the dam and Ijoth the other 

 bitches referred to before on the 28th, etc., days. 



They move about the yard from the first as if acquainted with it, and choose the com- 

 fortable shady places in which to lie. By the lip-call, etc., I get them to follow me back to 

 the kennel, but when inside the door they hesitate and soon make for the yard. When 

 placed in their usual compartment in the kennel after l)eing some hours in the yard, they 

 cry, but not long.
