V. Memmler 1942 31 Itinerary April 2, Berglund Ranch, 1250 1450 ft., 2 NW mi. N Corralitos, Santa Cruz Co., Calif. Dew of the night before. We had set out Museum Special Traps in the late afternoon the days before. We left a great number of traps where they were the night before, with walnut meats and peanut butter, but relbaited them. 10 were across the strip of brush between apple orchards. Here we caught 1 Peromyscus californicus, ? Along the edge of the brush near the ridge we set 96 traps. We caught 3 Dipodomys 2 ?, 1 q, 1 Sorex (?), and 1 immature Sylviagus ?. There were 6 traps sprung. Traps were spaced about 5 paces apart. One of the Dipodomy?) had carried himself and trap about 20 ft. down a steep slope. The trap was set on a fairly level space and just above a wood rats house. Trap set here Wood rats house Dipodomys and trap found here Yesterday of the three Dipodomys caught were all found about 15 ft. from where traps were set q. 2 of these were in traps and one out of a trap. This seems to show that the Museum Special traps are just a little small for Dipodomys.
