O. P. PEARSON 1949 Aug. 31 New trapline caught 5 Peromyscus, 12 song sparrow, and 3 Mueotus calif. Almost all near the ditch or stream. Nothing in the dozen or so traps out in a fallow field (Coarse grass and 1 ½ foot tall dead weed stubble). Left at 11 for home via Acreata, Eureba. Route 299 to Acreata repeats the vegetational changes noted in dropping down from French Camp to Weitelspee. Decrease of broadome etc. with increased altitude, improvement of Doug fir. Some riverine cedar as at French Camp and some large patches of prairie. There has been more lumbering, grazing, etc. along the 299 route, however. Stopped at Anita's two bat localities at Bayside and Falka and caught one or Corycorhinus at each. Also looked in a few more houses and bridges in the Eureba region but found no bats. Home 11 p.m.
