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 Pua levis, Agrostis exarata, 
Sporobolus filifolius, and a species of Hlymus, the most abundant grasses. 
This land was not irrigated, but is only 5 or 6 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 oem species 
and the main dependence for winter range. Greasewood and White 
Sage are somewhat abundant on the hills, and Dist (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.

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