often visited is not a frequented spot for tiie sheep, serving only 

 as a connecting link to Iron Mountain. Howe\er signs around 

 Ontario, Cucamonga and Telegraph peaks are abundant and any- 

 one with a little patience and diligent endeavor can readily see the 

 sheep themselves. They travel often in bands, as many as fifty 

 and in summer keep to the highest places. Where they go in winter 

 is as yet a mystery to me, probably lower into canyon heads for I 

 have never found them on the top during this season. This of 

 course is natural for these peaks practically become great ice moun- 

 tains dangerous for anything to tra\el o\er. Besides grass the 

 food consists of twigs and leaves of Castonapsis seinpewirciis, 

 several species of Ceaiiotlitis, Rluniniiiis croiciis ailiforniiiis, Rhus 

 trilobata and a parsnip Pasl'nuica saliva. 



Citflliis beecheyi. Richardson. California Ground Squirrel. 

 Abundant in all parts from brush land to 8,000 feet altitude in 

 suitable localities. 



Sciiinis yriseiis cuithouyi. Mearns. Anthony Gray Squirrel. 

 Very common in the transition zone. In early spring they start 

 working on pine cones on the mountain tops, gradually coming 

 down to more abundant supplies of food until fall linds them down 

 in the oak belt feeding on acorns. They winter as low as Palmers 

 canyon in some cases. 



Entamias Sp. Abundant in the pine belt and as high as the top 

 of "Baldy." They are good climbers, exceedingly acti\'e ami burst- 

 ing with curiosity. 



()ii\(li()iii\s torridiis ramona. Rhoads. San Bernardino Grass- 

 hopper Mouse. But two specimens of this carni\-orous mouse were 

 taken in a period of trapping extending over three months. Both 

 specimens were taken on bait consisting of rolled oats and in the 

 same place, east of Indian Hill in the brush. A good many of my 

 specimens were more or less devoured in the traps in this locality, 

 and I strongly suspect this mouse of the crime. Nowhere else were 

 my mice eaten or were any grasshopper mice taken. 



Perowxscus miiuiculaliis yavibcli. Bairtl. Ciambel Whitelooted 

 Mouse. This species was one of the most common forms taken, 

 being abundant in the brushy valley and foothills. There is a great 

 ileal of color \ariation in the specimens taken.
