Davis. 1940. Aug. 4. 3 1/2 mi. e. and 5 mi. n. Yacolt, 500', Clark to., Wash. rune of Microtus, and burrows were also found. A swale of sedge cuts across the meadow, and 1 trap line was placed along it. The other went out into the meadow proper. Sibley saw one Microtus in the glass, and said that it seemed smaller than the Microtus townsendi we have been catching. The holes also seem smaller than those of townsendi. We ran 2 other lines across the road. Mine ran along the edge of a dense thicket of Rubus sp. laciniatus, and un- der fallen logs. Russell & Chatti collected 3 conies at Shot bats after supper, and collected 1 Myotis evotis. Aug. 5. Ran trap line. 2 young + 1 adult Geomyscus, and 1 Sorex hoybridgii which I gave to Sibley.
