Cogswell 1949 Journal 63 Big Lagoon, Humboldt Co., Calif. Aug. 15 (cont.) I left 39 traps on the same line near Ritcher Creek as the previous night. Those left were in the Ribus & Sambucus thickets, along the old bed of the stream + 3 adjacent to the present stream. Nighthawks were seen over camp in the evening. Aug. 16 on the Ritcher Creek trap line (39 traps), caught the following: - Microtus californicus - 2 (see species acc.) Zapus trinotatus - behind tree trunk adjacent to stream bank, but backed by dense Ribus thicket. Peromyscus maniculatus - 1 ad. J, 1 im. J, The abrupt drop in the take on this line as compared with the previous night is perhaps significant. The second night was clearer, howerer, than the first. Murray & I arrived at the abandoned ranch on the west side of the ridge E. of the lagoon about 7:45 a.m. & took up our traps. In the 20 I set along a small draw with small alder, clumps & bushes (see yesterday's journal) the following were caught: Peromyscus maniculatus - 1 ad. J, 1 ad. Q, + 1 im. very much eaten by some animal after being caught. Sorex trowbridgi - 1 [illegible] (see species acc.) about 2:45 In the afternoon I walked up the slope across the bog pond from camp (& S. side of valley) & took photos of the valley which should show our text
