 seen wheeling high in air like a mere insect in 

 the great blue dome. It is said that he soars 

 as high as twentyfive thousand feet above the 

 earth. But to-day he sails alone and his tribe 

 has grown less year by year. With the eagles 

 he keeps well up in the high sierras and builds 

 a nest on the inaccessible peaks or along the 

 steep escarpments. He belongs to the desert 

 only because it is one of his hunting-grounds. 



This may be said of the eagles and the hawks. 

 They hunt the desert by day, but go home to 

 the mountains at night. The owls are some-
