 of the mountains, at the same pass ; and in the northern end of Vegas Yiilley, extend- 

 ing a short distance over the divide between Towner's and Ash Meadows. In this

 Cottonwood Springs, Vegas Valley; in .Johnson and Surprise canons, Panamint 

 Mountains; in a canon of the Inyo Mountains, near Swansea; between Keeler and 

 Crystal Spring; and on the east slope of Walker Pass. It contines itself principally 

 to rocky mountain slopes, seldom occurring on open mesas, and therefore rarely seen 

 in the bottoms of the desert valleys. It furnishes the best of grazing for stock.

 lected on the south slope of Browns Peak (No. 173), in Resting Springs Valley (No.
