Brode 1934 July 13 Friday the thirteenth. From traps on hillside Cat Creek 8900ft, Mt. Grant Mineral Co., Nevada, thirteen Peromyscus maniculatus and one Perognathus parvus and from the gopher traps in the Cat Creek Meadow- one specimen of Thomomys quadratus. From traps set near camp in Japan Canyon I took out during the day five Thomomys quadratus. Set traps for Microtus e. nevizi. a sector of boggy ground near the placer mine in Japan Canyon was extensively cross-crossed with trails noticeably containing Microtus droppings and pieces of cut grass. The runways were for the most part in quite moist ground. I placed the traps in the runways but got only two Microtus montanus. In mouse traps away from the bog I caught two Peromyscus maniculatus and in the reset gopher traps I found two Thomomys quadratus. In the afternoon we moved down the mountains to Cottonwood Creek 7500ft Mt. Grant, Mineral Co., Nevada. In the evening I went up Cottonwood Creek [?]900ft
