Pleasant Valley, Utah, August 18. 



Pleasant Valley is on the eastern slope of the mountains, bordering 

 the Salt Lake Valley. This is a very dry region, similar to that about 

 Green Kiver. Agropyrwn glaucum, A. repens, and E}ymus condensatus 

 are the more common species. Oryzopsis cuspidata is common on the 

 hills, and Poa tenvifolia, var., is also frequent. 



As in other parts of Utah and Nevada, the amount of wild grass now 

 found on the range is very much less than it was before the introduc- 

 tion of sheep, which seem to have killed the roots of most perennial 

 species, so that what was good pasture land five years ago is now 

 almost barren. 



Green Eiver, Utah, August 20. 



The bluffs here are high and barren. I found no cultivated land ex- 

 cept three small places on tlie river bank, and there are said to be no 

 other ranches nearer than the Lasal Mountains, 20 miles to the south- 

 east. The range here is so barren that no stock is kept. A rain about 

 July 1 wet the ground to a depth of about 3 inches ; previous to that 

 there had been no rain or snow since April 20, 1886. On the sandy 

 lauds along the river a number of coarse grasses were found, but on 

 the mesas and hills I could find nothing except occasionally Agropyrum 

 repens and Poa tenuifolia* var.
