and lush weedy + greasy stretches along the road and between folds, much lupine, small compositae bushes. Camped beyond Lugano on the grade up to the altiplano again, 11,500ft. A bushy terrain with numerous large cacti, bronto green thornbush, astrea and other bushes, some greasy syceras. Put out about 30 traps along a stone wall through this stuff, some clumps of cardua 10 ft tall, cardolabu joint cacti 10 ft also. May 16 Temp. 5:45 a.m. 45°, but some frost in places. My trap with about 5 Aboron bolinensis, 2 Phyllotis, several guaray empty, 3 of the mice eaten. Drive to Mazca. The road climbs back onto greasy altiplano with vicuñas etc at about 13,500ft, then drops down to Mazca (2500±). Lama vicuña in grass as low as 12,400ft. Phyllotis between 13 + 12,000, maybe a little lower. Not too sprinkling of grass down to about 10,000 ft. where the big Y tree cactus starts, then gradually diminishing vegetation as you get lower, some vegetation all the way down to the Mazca Valley, no completely bare stretches as on the Tacna road. Noteworthy were “preats” of a small foretree (milky sap, clusters of red pods at ending branches, no leaves). Cotton in bloom and ripening in the valley. Stopped for much bird shinning by a blooming cotton fields. Then rode good with Refords and parted. Camped on desert a few miles north of Mazca
