Fig. 148 — The Coast Range between Mollendo and Arequipa at the end of June, 

 1911. There is practically no grass and only a few dry shrubs. The fine network over 

 the hill slopes is composed of interlacing cattle tracks. The cattle roam over these 

 hills after the rains which come at long intervals. (See page 141 for description of 

 the rains and the transformations they effect. For example, in October, 1911, these hills 

 were covered with grass. )
