DESCRIPTION OF CAMPS 335 



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



The descent from the summit down the eastern slope was mucli 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 lias an intermediate situation 

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

 the goldiniuiufi 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 

 had gone farther down, where the farms 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, Sturnella ne- 

 glecta, Zonotrichia coroiiata, and Glaucidium cali/ornicum, which assembled in numbers 

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

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

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

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

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