forage crop. Redtop and timothy are both abundant along ditch banks 

 and on wet ground, and a i'ew wild meadows are almost wholly redtop. 

 One field of red clover was seen, but the crop was poor, and alfalfa 

 will be sown in its place. On the mountains good pasture is found all 

 summer, while the bench lauds too high for irrigation become so dry as 

 to be almost barren, except for occasional plants of Stipa comata and 

 Agropyrum glducum. Erodium cicutarium is found occasionally, and is 

 said to be becoming more abundant. Agrostis vulgaris var. (Redtop) 

 is abundant on moist soils, and Hor ileum jubatum (?) is a troublesome 

 weed in exhausted land. 



The upper part of the mountain has an abundant supply of grass, 

 and stock find good pasture here all summer. The same is said to be 

 true of all the mountains in this vicinity.
