Fig. 1. University Peak, 13,588 feet, and Pothole Lake, Kearsarge Pass, 

 in Fresno and Inyo counties, as photographed September 1, 1916. Sign of bushy- 

 tailed wood rat was found among the vertical broken rocks which form the crest 

 of the Sierra Nevada at Kearsarge Pass. The species was found in numbers on 

 both slopes of Kearsarge Pass up to and even above timber-line, which is here 

 indicated by the stunted growth of white-bark pine to be seen in the left fore- 

 gi'ound. 



Fig. 2. Habitat of bushy-tailed wood rat in Kings Kiver Canon, 5000 feet, 

 Fresno County, as photographed September 15, 1916. The animals were found 

 inhabiting the granite talus slope shown at the right of the illustration. This is 

 about the lowest limit of the range of the species. Here individuals were found 

 associated with sugar pine and golden oak on the hillsides and even among the 

 willow and cat-tail thickets on the floor of the canon.
