plains it is much prized as firewood. The following detailed notes on 

 its distribution were recorded : 



CALIFORNIA. 



Canada de las Uvas. — Common at an altitude of 1,070 meters (3,500 

 feet), ranging from Oastac Lake eastward to the extreme west foot of 

 Antelope Valley and also occurring in a wash leading thence south- 

 ward toward Peru Creek, where it is mixed with stunted tree yuccas 

 (altitude 760 to 910 meters or 2,500 to 3,000 feet). 



Walker Pass. — Common on the east side of the pass from 1,430 meters 

 (4,700 feet) to summit (1,550 meters or 5,100 feet), and much higher on 

 mountains on both sides. On the west slope it covers the whole pass 

 down to 1,240 meters (4,100 feet). 



Kern Valley. — Found on a steep north slope in the Kern Eiver Val- 

 ley as low as 820 meters (2,700 feet). 



East slope of Sierra Nevada. — Abundant all along the west side of 

 Owens Valley and ranging thence up on the Sierra as high as 2,740 

 meters (9,000 feet). 



Owens T 'alley. — Covers the whole valley from its northern end down 

 to within a few miles of Lone Pine, descending to about 1,100 meters 

 (3,800 feet). South of Lone Pine it is confined to* the west side of the 

 valley, where it follows the cold streams that come down from the 

 High Sierra and is common on the slope above 1,550 meters (5,100 feet). 

 In a few places it reaches the narrow valley between Owens Lake and 

 Haway Meadows. It is absent from the warm slope at the foot of the 

 White and Inyo mountains on the east side of Owens Valley, but 

 begins as low as 1,980 meters (6,500 feet) on northerly exposures in 

 the latitude of Big Pine, and ranges up over the White Mountains. 



White and Inyo mountains. — Abundant over most parts of the sum- 

 mit of the range, often forming pure sage plains of considerable extent 

 and ranging down to about 2,280 meters (7,500 feet) on the west slope 

 (Owens Valley side) and to 1,920 meters (6,300 feet) on the east slope 

 (Deep Spring Valley side), but does not descend into Deep Spring 

 Valley. 



Panamint Mountains. — Common along the summit of the range, de- 

 scending as low in places as 1,980 meters (6,500 feet) or even 1,920 

 meters (6,300 feet). On the west slope of Telescope Peak it grows as 

 high as 3,050 meters (10,000 feet). 



Mohave Ptesert. — Found on the summit of Cajon Pass and thence 

 along the upper part of the Mohave Desert at the foot of the San Ber- 

 nardino Mountains, occurring sparsely among the junipers down to an 

 altitude of 1,160 meters (3,800 feet), where it is replaced by Atriplex and 

 other genera. The altitude of the Mohave Desert as a whole is too low 

 for sagebrush. 



NI5VADA. 



Fish Lalce Valley. — Not found in the bottom of the valley, but de- 

 scends from the White Mountains to about 1,680 meters (5,500 feet)
