PEARSON 1955 Tree around houses. Some cultivation at 13,000 ft, and at 12,500 trying to be quite furnish. Stopped at a side road to mine at 13,000 ft in a Huarque-like gorge. Floor is good green grassy turf, sides dense bunch grass. A few small patches and trees of brush. At 12,500 it was certainly too temperate for pterocarpus, and here may not be bushy enough for ardisium. Pant about 15 traps in the a weedy-bunchy patch near the stream, about half a bog under boulders etc. on dense bunchy grass hillside, and another half log up a steep narrow chute going to grass + sphaqnum. This locality shall be known as 10 mi. NE Cerro de lasos, aug.18 Traps held 10 abdonum, 1 long-tailed Oryzomys, 2 Metanymus, 1 Abdonum jelskii, and 1 Hezipromyz. No Phyllotris! While picking up the traps I realized that there was no bare ground - hence no Phyllotris. Drove down the canyon to below Huarvica where the other Cerro de Paso road comes in, at about 12,000 ft this are many kinds of trees and bunches, a few orchid plants seen, and vegetable garden with collage, lettuce, onions, plus geranium and roses. Although some bushy areas, considerable grasscover. By Huarvica, howerer, things are dryer again, with cactium plants on the walls, and open brush. Especially between Huarvica and the other road (10,500 ft.) there are bushy hillsides with open stoney ground in between - looks good for
