July 5 3 km E. Humay, Pisco Valley, 1400 ft., Defl. of Pica Broke camp at Pacacave and drove to Surin to talk with Dr. Hermódi de Macedo concerning lizard staying at Ada Cheyarin. All OK. Then headed south. Good tilandrin between Surin and Pucunsoa and also at about San Antonio. First tile at Wala. Good sandy desert between Wala and Canete. Stopped at one place where we saw one lizard, 1st troche, and lots of mouse troke, especially along boulders below the road cut. Only plants seen were some cactus growing on a very old skull and 1 tillandrin across the road a few hundred yards away.

July 6 Andy's traps, set at dusk mostly along a stone wall, them bare bare dry ground caught 6 Phyllotis darwinii. Left after breakfast and drove off the Pisco Valley to 10,000 ft (above Ticrapo). Cacti begin about 3,000 ft., shrubs begin about 5,000; maximum bushes are at about 9,000, than it begins to get brush-grassy. Had lunch by a waterfall at 10,000, then went back to only reasonable campsite at 8,000 ft (2 mi. E Ticrapo). Here there are scattered shrubs, many of them spring, some bark covering, some saguaro cactus, some cereus cactus, some lone fig-like trees. Not as bushy as our Phyllotis magnater site above Tarata nor as
