One more Clothronongs, 5 Peromyscus, and 1 young Meotus in traps. Left after breakfast for the big prairie around Schoolhouse Peak. Set 49 oatmeal-baited Shermana and 6 Museum Specials mostly along a wet sedge seep but a few out in grass, the edge about 100 yds from a torqne of oaks in a ravine. Watched ground squirrels and Murray I found 2 Myotis erebus in rock crevices. Put out two gopher traps around camp and caught one before supper. Early supper and drove with Murray + Cogswell to Schoolhouse Peak. Just before dark set about 30 oatmeal-baited Museum Specials in moist woods on north slope near cattle gap east of the five stages. Woods in Doug. fir, madrone, and tan oak, with thick duff, rotten logs, etc. Many tunnels etc. Most sets were "Blarina" sets at natural holes or holes poked into tunnels. Sat by water trough until dark but saw only one bat didn't drink. Lights of Euscevaria ble. Aug 23 Trip line in sedge seep in prairie caught 2 Sorex vagrans, 1 Mictus californicus, and 6 Peromyscus.
