Itinerary Palmer 1937 Jan 6 Cont'd. Elsinore, Riverside Co., Cal'd. Traps were mainly set on the slight hummocks or ridges where the burrows were not under water. Drove on down the south side of the lake to a place 4 mi. SSE Elsinore, 1300 ft., Riverside Co., Calif. Then made three sets of Macabee traps in fresh burrows in an orchard. Soil here was brown and slightly clayey. Returned to Ontario in the rain. Jan 7 Left Ontario 11 A.M. and drove via Corona and Temescal Canyon to Elsinore. In the 12 sets 3 mi. NW Elsinore, 1350 ft., Riverside Co., Calif... I found 7 Thomomys bottae. Then drove on and picked up the traps 4 mi. SSE Elsinore, 1300 ft., Riverside Co., Calif. where there was 1 Thomomys bottae taken in the 3 sets. Then drove on down the road through Wildomar, Murrieta and Temecula at 2 mi. S of Temecula and turned off east on the road to Aguanga. Ate lunch on the way and arrived at Aguanga about 3 P.M. in a snowstorm. Decided I couldn't camp out in the storm so
