with us two which were caught in live traps. For trapping purposes we decided to try another area closer to Flat Creek Ranger Station. Took a dirt road toward the creek which led to an abandoned ranch and a fairly nice campsite along the stream. The trapping areas now varied - fences, old stream bottom with moist grassy places and dead willows, dry open grass and rock exposures. I caught nothing in my live, & Draiella caught 1 Peromimulus. I saw many bats flying over the stream in the evening - seemed to be feeding on the insects which were very numerous about 2 inches above the surface. Aug. 13, 1951 Drove home through Marion. Reached Berkeley about 4 PM.
