S.O. Landby 1950 Journal May 6,7 4 Mi. N.E. Pope Valley, Pope Creek, Nappa (o. Calif) Left Berkeley, 2.00 P.M. Stopped at Alginum (Howell Mountains) looked through old barn for bats. 1 Myotis thysanodes. Arrived at Camp around about 6:00. Set out Trap lines. Mine ran up the side of a steep hill away from the road about 40 yards from the bridge. 15 traps. 10 "museum speciels", 4 ordinary house, more traps and 1 live trap. One of my traps at the base of the hill, on the edge of the road caught, 4 mice. 2 of them less than 30 minutes apart. The live trap got clogged with dirt and failed as a trap. Caught a total of 9 mice. The trap up the hill caught mostly Peromyscus truei but the large # of there had intermediate measurement between truei and maniculatus and may have been P. boylii. The trap line went up the hill 75 yards or so and turned along the edge of the top following what was apparently a deer trail. Bait was oatmeal. Tried for beets again in an old mine. Could not find it. (This was somewhere west of Pope Valley.) Besides, the 2 Peromyscus's mentioned above, the other mammals obtained were: Peromyscus maniculatus, Rheithrodonmys megalotis, Sanex thowbridgii (cought alive) Noctipmutes taken. Birds included 2 Cliff swallows and 1 Vaux swift, shot. Weather was warm and clear. Daytime temperatures running about 75.
