Pearson 1949 journal Aug. 8 Big Lagoon, Humboldt Co., Calif. Left Berkeley 5:45 a.m. in Dodge with Cogswell; Miller, Murray, and Sullivan in other car. Route 101 all the way to Big Lagoon where we arrived about 6:15 p.m. Only mammal stuff en route was at Benbow Hotel where Cogswell and I took a quick look in the stable for bats. People + horses were living in it, saw no good bat places in this building. Set out 70+ museum specials baited with walnuts in thick grass, weeds, + salspina on east edge of lagoon where ranch road crosses creek. Saw no runways, droppings, or cuttings. Many low-flying small bats at late dusk over ranch road between forest + Lagoon. Also put out 2 steel traps unbaited after dark. Aug. 9 My traps in March held 3 dormice and 5 Zapus. Cogswell along brushy edge of spruce woods caught Pero and Sorex trowbridgii; Murray Peromyscus. No microtines! Looked in ranch buildings for bats but few good places for them. Underneath ranch house seems satisfactory for Caryophs but nobody home. Put out 50 Sherman live traps baited with walnuts along the log "wall" below the big log pond - mostly on the edge of or in thick salspina. Saw one set of Microtine? droppings there, also 3 raccoon sets along stream and 3 other steel along log "wall". Also set 35 Museum specials in smoggy gloomy spruce woods baited with walnuts. Sullivan set 33 in same sort of place.
