DESCRIPTION OP CAMPS 335 



d. The eastern slope (July 10-12). 



The descent from the summit down the eastern slope was much more 



rapid than had been our ascent of the other side. The forest, however, 



continued much the same, but the trees were appreciably smaller, becoming 



more so as we descended. The only new bird detected during our hurried 



August 15 and December 15, 1872."] "This locality Las an intermediate situation 

 between the lofty peaks and the foot-hills of the Sierra Nevadas, and is in the midst of 

 the gold-miuiug region. My visit being in the last of the dry season, when the vegeta- 

 tion is dried up by the hot sun, probably many of the spring and early summer residents 

 bad gone farther down, where the fiirms are more numerous and less parched than 

 the uncultivated hills surrounding Nevada. 



In November, while collecting twenty miles farther down, we found many species 

 abundant which were rare at Nevada; among which may be mentioned, Sttirnella we- 

 glecta, Zomtrichia coronata, and Glaucidium californicum, which assembled in numbers 

 around our camp-fires every night and serenaded us with their curious notes; [¥ote. — 

 Mr. Ilenshaw suggests that this owl may have been Scops flammeola, which has this 

 habit, while the Glaucidium is diurnal and crepuscular.] also, Lophortyx californicus, 

 Oreortyx pictus, and many others, were observed on the cultivated flats, which were 

 rare at Nevada." We give below a full list of the species found by Mr. Nelson at
