O. P. PEARSON 1949 the trap line runs are chiefly older + maple with a few old Dany firs. Many swordferns & madenbr, considerable more. Soil fine sandy. Bats started flying in our globs well before dusk (6:40). Shot one myoptis volans and netted 4 M. calif. before dark, aug27 Trip line yielded 9 minimilutia, 1 josep townbridgei, 1-2 proffice, and 1 minutus oregonii. Shined thru and bats in a.m. started to put out another line in pan. but saw a piggy owl being scolded by more or less tits so shot him with .22 rifle and came back to skin him. He was in brush + oak & later added about 20 more museum specials baited with oatmeal to my original line along Coon creek. The original 5-6 long or nothing during the day. Bats appeared at 6:41. Tried the concussion theory on them. First shot with .12 ga. caused one to tower upwards slowly in what seemed to be a confused fashion. He did not alight, however. Two more shots were without obvious effect. I don't think any of the bats involved were Myoptis volans. Probably Californica. Tried setting again but didn't get any. Mr. Patterson of the @ Ranch stopped in. First reach between here and Willow Creek. He didn't seem to know much about the animals around here but on his summer range in the hills above Horse Lento (± 5000-6000 ft) he talked about mountain beaver, chipmunks, bushy-tailed woodrat.
