Hoffmeister 1942 Itinerary Walker Cr., 4 mi. SW Clueka, 5200 ft. Suyo Co., Calif. hunt owls, we saw 8+ bats, apparently all Myotis. Russell shot one which was apparently Myotis subulatus. May 19 Set 45 traps on the hills west of Walker Creek, in a sparse mixture of Artemisia, Chrysothamnus, sparse grass which had seed heads, and other low chaparral plants. Caught 3 Peromyscus maniculatus and 1 Dipodomys. 35 traps, which were left set from the day before, along Walker Cr. caught 5 Peromyscus boylii, and 1 Ctenodiporus tesselatus.

This is the same canyon I unsuccessfully hunted grey squirrel in yesterday a.m. May 20 Set 60 traps on the west side of Walker Cr., paralleling the creek, in Artemisia, small amount of Chrysothamnus, and Lupinus and buck-bush.

Got the part of a tail of a Perognathus. Caught only 1 Reithrodonmys in the traps set along the creek. Shot a cottontail while running my trap-line, which had 3 embryos (saved in formalin), no. 582. Four Schwyer traps set around wood rat houses (apparently
