687 Mad R. ford, 2700 ft., above Ruth, Trinity Co., Calif. May 29, 1933 Helped up all my traps get near the summit of Horse Ridge. The catch of Eutamnes sonomae and Loxia knowltdji seems definitely to fix the mammal fauna as Transition. Brouse heard booming on day ridge about 3500 ft. alt. Pair of Mt. Luan's seen at 5500 ft., Blue Fronted Jays noted all the day from valley floor to 5500 ft. A rest day - as have been the two preceding. Arrived in camp about noon and abra remained there all rest of day. May 30, 1933 Finished up the mammals from trap line & Ginnell and Behle and packed trucks for departure. Left Mad River ford about 8:00 P.M. - stopped in at the Independence Try farm, which had two fogs, Citizens Conservation Camp where we met Mr. Asplund, Forest Ranger & were directed to Goose Mountain via Eureka, and finally at Mr. Feed- Muller's sheep ranch where he also left.
