Note 9 — XVII

Basira ravine.In the afternoon we reached a vast ravine, called “Basira,” 973 meters above Uacloy, and about 1,134 meters above the sea, extending from south-east to north-west between lofty, precipitous ranges, covered with wood. Its base, which has an inclination of 33°, consists of a naked bed of rock, and, after every violent rainfall, gives issue to a torrent of water, which discharges itself violently. Here we bivouacked; and the Igorots, in a very short time, built a hut, and remained on the watch outside. At daybreak the thermometer stood at 13.9° R.9
