1951 P. PEARSON Lima Peru Nov. 17 Went with family by bus to Lima to look for bat tunnels (about 20 miles east of Lima). On the barren slope southeast of the bus stop found 3 nice mine tunnels in rock. Droppings and bat smell in all but no bats. The droppings were quite heavy, homogeneous, possibly dampish. Nov. 19 Went back to Lima to look in some tunnels south west of the bus stop (east of the big new Avila farm). One good horizontal tunnel and 3 vertical tunnels. Good droppings around entrance of all but no way getting into the vertical ones. I think one of the vertical ones was the one from which Gardner, Hertig and Fogel bats in 1939, but the timbers are now gone and no way of getting into them without rope ladder. Nov. 23 Left at 7 a.m. on train for the mountains - all up hill after Chosica and gradual transition to altiplano conditions. Most of rocky and steeply utilized. In several places were old terraces, not used, and right beside them cultivated fields on steep slopes. Don't know why the old terraces are not utilized. The high country is much less interesting than southern Peru. Saw no ducks, geese (some shore birds), caracaras, albatrosses, flamingos; only a few llamas and sheep. The rivers are polluted by mining activities. Hills around Oroya are totally bare (from smelter furnaces?). Got off train at Pachocayo upon advice of people on the train because here there were supposed to be terraces and a hotel. No hotel. Only a big Cerro de Pasco
