Pitetska 1943 June 25 1 mi W Tyngscon, 1200 ft, Trinity Co., Calif. right in thickets of dead brush and grapes and along a marginal willow thicket about the bases of the trunks. Only one immature male Peromyscus maniculatus (and one juvinal Brown Towhee, apparently just out of the nest) was caught. June 26. Hunted on the flat during the earlier part of the morning. In addition to comments made earlier regarding the general habitat here, I would mention that Lambucus as a large shrub or small tree together with scattered thickets of Rosa and Rhus diversiloba and trilobata occur on the higher areas between and among the cottonwood and willow groves. Further- more, the presence at least one incense cedar and one yellow pine on the western part of this flat would indicate that at least there, the flat was originally covered with a forest comparable in character to that on the slope to the north. Later I moved to the south-facing slope west of camp, observing and collecting plants more than hunting. I followed a cattle trail up one of the draws, perhaps 305 feet, into the area where scattered chaparral patches occur
