P. PEARSON 1955 I followed about 50 yards ended under a 10-inch stone, not on a mina mound, and there was a Hesperomyza in a grass nest. He was quite tame. Taylor along small canught 3 fth picture and 1 Hesperomyza. After about 6 a.m. the miner birds started popping in and out of the mina burrows, as well as the burrows upon the hillside. I am convinced that they are the principal occupants of the mina burrows. a schoolmaster looking passerby said the mina mounds were the result of growth of a certain plant with edible seeds that the Indians used to eat, but that the plant has been gone about 300 years as a result of grazing. Several other sets of mina mounds appear between Miracaca and Ceno de Paseo, with perhaps the biggest of all at the Canta turnoff. Wherever there were mina mounds, the road cut showed an upper layer about 10 inches deep of stony soil, underlain by a layer of almost pure stones, most of them under 5 inches diameter. Took the eastern road from Ceno de Paseo down toward Huaraca. The road goes down a steep canyon with many traces of old Spanish mining activities. Traced down to about [early about 26] 12,500ft, where a smallboy said it was about 6 km. further to Huaraca. The steep canyon sides become rather lush brush grass, then, southward, a brushy zone, Queñoa trees appear. Antena (or something similar) and grass. Between 13,000 and 12,500 often also evelly flats and a walnut-looking
