Peteika 1943 June 20 Zuni & Hayfork, 2400 ft. Trinity Co., Calif. a mixture of yellow pine, digger pine, black and garry oaks with an underbrush of manzanita and Ceanothus (cuneatus). On the lower east facing slope, the trees are more densely placed, the pines are all ponderosa, and the underbrush is a low, more or less spreading shrub of the genus Ceanothus, (species yet determined). Higher on the west-facing slope, digger pines are more numerous, the under thins out generally, and indivi- dual trees (chiefly oaks and digger pines) are scattered over slopes covered mainly with Ceanothus. Yellow pine occurs mainly along the draws. On the higher parts of the west-facing ridge, there are large areas of chaparral dominated by Ceanothus and Adenostoma. The shrubs of the latter genus are dead, however. It is possible that here this chaparral species occurs along the periphery of its range and may develop as a constituent of the local chaparral only intermittently, i.e., over a number of years during which climatic conditions may be favorable. June 21 Hunted again in Duncan Creek with a view to going further north than yesterday. I probably went up about a mile. No
