after noon clouds usually rolled up the valley surrounding us in fog; the 

 ridge at the end of the valley was seldom seen in the afternoon. 



"From the Paramo, on September 2, we retraced our steps through the 

 12,000 foot woods to a vacant house at 11,500 feet, intending to remain 

 several days and work the woods. We left on the third day, however, 

 after making 75 skins, for we found that the fauna was not strikingly differ- 

 ent from that of Laguneta." 



Cartago to Novita. — "We left Cartago December 7, Miller having been 

 fortunate enough to locate some oxen going to Salencio. Crossing the 

 river the valley is more rolling than on the other side, but just as arid. 

 Forty minutes brings one to Anserma but the trail branches off just before 

 reaching the town and soon winds up a long ridge to an altitude of 6800 feet, 

 drops across a valley to 5800 feet, and then rises again to 7800 feet. This 

 country is much like that across the valley on the Quindio Trail, and the 

 birds, so far as observed, likewise. There is little sign of humidity until 

 6800 feet is reached where moss on the trees and an abundance of ferns 

 bespeak of the ' cloud zone.' There was little or no bamboo except along 

 one stream low-down (3800 ft.) and no apparent change in the birds until 

 this upper zone (above 6800 ft.) was reached. This humid forest reached 

 its greatest development on the western slope of the ridge although it was 

 very distinct on the eastern slope down to 6800 feet. On the western slope 

 it extended down to perhaps 6000 feet. (I have not this altitude exactly.) 

 On the top it is extremely rank and luxuriant — far more than we had met 

 before, although perhaps not more so than at San Antonio. Birds were 

 very scarce, as usual in this humid forest; the trail descends very steeply 

 from this forest through more or less cleared country to Salencio, at an alti- 

 tude of 5,500 feet. Here we staid two days while Miller engaged the peons 

 for the rest of the trip. In the river valley (5000 ft.) below is a heavy 

 growth of bamboo. Between this and humid forest (at a little distance 

 from town) is a good forest growth of an intermediate nature. 



"Leaving Salencio the trail follows up the river Bueltas, a small, dashing 

 mountain stream — much like the Santa Rita near Salento — with luxuriant 

 woods or mossy cliffs on either side, much moss, epiphytes, etc. It is a 

 typical Cock-of-the-Rock stream, and we had not waded many miles over 

 its slippery rocks or on its mossy logs before I got a nice male of Rupicola 

 sanguinolenta. After leaving Salencio we knew scarcely a dry moment 

 till we reached Juntas. The first night at an altitude of ^00 feet, it rained 

 all night, and we had neither tent nor blankets, for the peon carrying them 

 deserted us without our knowing it. 



"The trail follows up the Bueltas to its very headwaters (alt. 6,600 ft.) 

 where it leads sharply up the mountain through deep crevices or guUeys,
