Koford, R 1925 Journal Sagehen Creek Field Station, 6400 ft., 3 mi. NW Hobart Mills, Nevada Co., Calif. 19 October denser rocks near the top of the hill. All there were kept alive to be taken back to Berkeley in order to get blood, kidney, and liver samples. I also caught a Neotoma cinerea in the dense rocks. I killed it in the early afternoon. Also, I caught another P. mericanus in a museum special in the scattered boulder area and a Dipodops ordii in the scrub area below the rocks. Bonnie Bowen and Dave Krohn both caught Microdipodops, making this a new locality for the known subspecies. A couple Perognathus were also caught. We then returned to the field station area, ate breakfast, then picked up the traps in the area. I caught nothing in the 10 museum specials set by the Sagehen Creek road where it meets Hwy 89, but Bonnie Bowen got an Eutamias species and an E. amoenus there. I found a shrew in one of my 5 museum specials by the creek - the same trap that caught 2 Microtus yesterday. I let the chipmunk which I'd caught near the meadow on Oct. 18. The chickaree died in the Tomahawk trap she was being kept in sometime during the morning. We spent the early afternoon putting up specimens, collecting traps, cleaning the buildings, and packing up to go home. We then left at 1445, returning to Berkeley. The sky was mostly clear, temp reaching the mid-60s (°F), wind light. Several specimens of mine were frozen and taken back to Berkeley to be prepared at a later date.
