1916] Dice: Land Vertebrates of Southeastern Washington 317 



The brush often grows so thickly that it is very difficult to force one's 

 way through it, but it is likely to be in clumps and there are many 

 open places. Rock outcroppings are numerous. The height of the 

 brush is usually from four to eight feet, but around springs or 

 damp places it may grow much higher. There is much down and 

 partly burned timber in some parts of the habitat, and an occasional 

 stump or tree has survived the fires. Young conifers are springing up 

 in places and of these the lodgepole pine (Pinus murrayana^ _is most 

 numerous on the ridges. On the lower slopes the buckbrush habitat 

 overlaps in some places the range of the yellow pine (Pinus ponder osa] 

 and isolated old yellow pine trees may often be found growing in 

 among the shrubs. 



Trapping on August 3 and August 9, 1914, in buckbrush on the 

 ridge near Twin Buttes R.S. produced 1 Peromyscus maniculatus gam- 

 belii, 1 Evotomys gapperi saturatus, 6 Zapus princeps or eg onus, and 2 

 Eutamias amoenus amoenus from a total of 50 trap-nights.
