Hooper, 1936 Rock Cr., 5000 ft., Granite mts. Washoe Co., Nev. July 11, green-tailed towhee, mourning dove, yellow warblers. Saw no chipmunks, though they should be here - the country "looks good". I could see no conifers - Juniper or pinyon pines - up to an approx. altitude of 7000 ft. July 12, Set out 30 mouse traps last night along the edge of the creek for Sorex palustris and Microtus mordax. Part (about 1/3) of the area trapped was covered with aspen, birch and alder, under which was a sparse growth of grass. The other 2/3 of this area the trees had been burned off; the Artemisia was, there, almost to the water's edge - having advanced into the burned area. No traps were set about 100 yds. from the stream on a south- facing slope and under Artemisia clumps and around rock piles (talus). Caught this morning: 8 Perognathus parvus and 1 Peromyscus maniculatus. Three of the pocket mice were caught at the edge of the water (not over 5 in. away) in the burned-over area. The other pocket mice were trapped on the hillside under Artemesia, the Peromyscus in a talus. Four specimens (all Perognathus) were sent.
