Chatting 1940 Catalogue 18½ mi. NW Portland 1300 ft. Washington Co. Oregon at distances of 3-10 yds. apart. Traps were set in small grassy spaces and beneath bushes and fallen logs and driftwood. Vegetation present along the trap line was made up of Bracken, tangles of black- berry, black raspberry, thimbleberry bushes. Young alders 8-18 ft. high, Carex sp? and some grasses are also present. White Everlasting, Clarkia and Canadian thistles add to the tangle of vegetation. 9 #4 jump traps were set in runs or burrow mouths of Aplodontia beneath fallen and rotten logs on NE facing slope of hill in fairly heavy stand of Douglas fir. 6 Traps were also set by W.C.R. and when I returned 2 hrs. later at 3 p.m. 1 Aplodontia was caught and 1 other trap was sprung. This contained some fur and possibly was sprung by feelly of the animal and was not held by trap. Traps are large enough since the A caught was held securely. 1 mole trap was set near camp in mole run which appeared fairly fresh (possibly not more than 3-4 days old). Between 8:05 p.m. and 8:30 p.m. shot 1 Lasionycteris and 1 Myotis. Bats were observed flying only between
