house's jay was notable in the same way on the 

 hillsides, in thickets of "cat-claw." Steller's jay, 

 noticeable at all times in the pine forests on the 

 summit of the range, visited, as did the pinon jay,

 the subject set forth in great detail the result of 

 observations made here. The pine forest on the
