Stipa occideniaUs.

Elko, Nevada, July 28. 



Elko is near the headwaters of the Humboldt River, in a valley from 

 1 to 3 miles wide. But little of the land is irrigated, but where fenced 

 it is seen to produce a fair crop of grass in its natural state. In one 

 meadow, 6 miles east of the town, I found Poa kevis, Agrostis exarata, 

 Sporobolus filif alius, and a species of Elymus, the most abundant grasses. 

 This land was not irrigated, but is only 5 or feet above the level of 

 the river, and the yield, I should judge, would be from one-half to three- 

 fourths of a ton per acre. In the same meadow are occasional patches 

 of Beckmannia, or "wild timothy," which is regarded as the most val- 

 uable grass here, both for forage and for hay, but it will grow only 

 where it can have abundant and constant moisture. On the drier mead- 

 ows and foot-hills Elymus condensatus is the most abundant species 

 and the main dependence for winter range. Grease wood and White 

 Sage are somewhat abundant on the hills, and Distichlis (Salt-grass) 

 covers many acres along the river. 



Collections were made as follows : 

 Elymus condensatus. 



Quite common, but not eaten in summer if other feed is to be had. 

 It is sometimes cut for bay, but is of poor quality. 

 Beclimaimia eruccvformis. 



Common on the river bank and in swampy ground from Elko to 

 Reno, and is everywhere one of the most highly valued species. 

 It is more abundant here than at any other point on the route. 

 Agrostis exarata (Redtop). 



Somewhat common. 

 MeJica stricta. 



In one locality in clefts of the rocks on the mountains. 

 Sporobo lit s asperifo I ius. 



Common at the edge of a hot sulphur spring. 

 Agropyrum diver gens. 



Common on the hills. 

 Festuca micrastachys. 



Common on the hills. 



Ogden, Utah, July 31. 



Ogden is in Salt Lake Valley, 10 miles from the lake,, with high 

 mountains on the opposite sides. The valley is watered by the Ogden 

 River, and is mostly under cultivation, alfalfa being almost the only
