one case three deer were seen in the evening standing out in an 

 open meadow hardly one hundred yards from a band of grazing 

 horses. The latter appeared to cause the deer no uneasiness. 

 As far as we observed, however, the deer were not themselves 

 grazing. Deer trails beaten into plain thoroughfares led across 

 heads of ravines and over ridges diagonally, but seldom followed 

 directly along the top of a ridge for any distance. 



In the vicinity of Round Valley, 9000 feet, four deer were 

 seen ; sign was noted July 27 up the brushy side of San Jacinto 

 Peak above Round Valley to an elevation of about 9800 feet, 

 this being practically at the upper limit of Ceanothus cordulatus. 

 Deer thus range in summer over the highest parts of the moun- 

 tains, there being no apparent zonal limitation. 



On Thomas Mountain and on the chaparral slopes in the 

 vicinity of Hemet Peak and Oak Tree Spring above Kenwortliy, 

 sign was plentiful. On the Santa Rosa Mountains evidences of 

 the presence of deer were not notably numerous, though the 

 animals ranged over the whole ridge. But down on the north- 

 east slope in the pinon belt sign was plentiful. On Sheep Moun- 

 tain, about the head of Deep Canon and across Pinon Flat to 

 the upper walls of Palm Canon deer were numerous. The lowest 

 place of occurrence was at Potrero Spring. 3500 feet, near 

 Asbestos Mountain; here one was seen June 13. 



Hunting of deer is persistently carried on through each open 

 season, and it is surprising, that there are many deer left in such 

 a limited area as is the portion of the San Jacinto region suitable 

 to tlie animal's needs. Their survival is doubtless due to the large 

 areas of heavy chaparral, which afford cover, and in many 

 places freedom from pursuit with dogs. 



Our parties procured three specimens: a two point buck (no. 

 2336) with horns in the velvet, near Toro Peak June 29; an old 

 doe (no. 2338) in Tahquitz Valley, July 24; and a spotted fawn, 

 female (no. 2337). Thomas Mountain. August 20.
