 and Bum. It can be lightened up at times so as hardly to be

 comes to maintaining their rights in the kennel ; and for months

 Bum were larger and stronger than their mates, and held the bal-

 The idea was abandoned for two reasons. First, it would absorb 

 too much of my time ; and, second, after reading Mr. Russell's *

 when the thing of real value for us is the spontaneous, uninter-

Some few things had to be taught, such as coming at call and 

 whistle and individual names, and retrieving was taught for a 

 special purpose to be mentioned later. In addition to this, lit-
