1955 O.P. PEARSON journal Chosica, Dept. of Lima, Peru Aug. 5 about noon set 48 Swedish mouse traps baited alternately with peanut butter and walnuts. Rat-sized droppings in 4 places and a few smaller droppings elsewhere. The locality is [illegible] east of Santa Eulalia and about 400 ft higher than the town. Traps on south-facing slopes. Hill very rocky (gravel) with big talus rivers, very little soil. Several cacti, fuzzy cylinder cactus, joint cactus, barrel cactus, tomatoes in flower and fruit, a white-flowered fig-like shrub, a few flowering and dried compositae, and dry grass. Saw lizards, doves, humming, finch?, guans??, wasp, butterfly. Photo 1-1. Lots of seeds around. After shopping in Chosica, set 20 more Swedish mouse traps on a gravelly stony hillside across highway from the Mana RR station. Many sheep droppings and numerous rat-sized droppings. Only vegetation is Tillandsia and a few crusty lichens. Found some very old bones that looked like viscacha or chinchilla. The big droppings could be chinchilla. Aug. 6 Slewed at Mana station drifting met and enough drizzle to need windshield wipers. Trapline a couple of hundred feet above the road was in a foggy peak fog, as it was yesterday am and when jacklighted there last night. [illegible] Didn't see any mice or merbles while jacklighting. One Ch. Darwin in these traps near Tillandsia.
