September 12 found us wending our way along the Quindio River toward its headwaters. The valley floor is covered with grass that is kept close-cropped by cattle and horses. Low shrubbery grows along the river-bank; the stream—not over one hundred feet wide—is clear and swift and the icy water rushes over a boulder-strewn bed. A scattered growth of tall palms dots the entire valley and extends up the mountainsides to an elevation of about nine thousand five hundred feet.
The trail is so indistinct that Allen and I, who were riding in advance of the pack-mules, lost it and spent two hours in a vain endeavor to recover the way; then we saw the cargoes and peons far below, resembling moving black dots, and hurriedly rejoined them just as they were leaving the valley for the abrupt slope. The trail from here onward was steep and rough. Before us stretched a seemingly endless succession of ridges, farallones, tall rocks, and high precipices that reach a climax in the brown paramo of Santa Isabel, backed by walls of gleaming snow. In looking back over the way we had just come we could see the Quindio and the thousands of palms growing in its valley spread before us like a map.
The lower slopes were barren, having but recently been burned over; fire was still raging in a number of places and the hissing and popping of burning vegetation could be heard frequently with distinctness. Tall, smouldering stumps were clustered here and there like blackened chimneys from the tops of which wisps and columns of smoke ascended into a hazy sky. The pungent odor of burning green plants was at times almost suffocating.
Forest begins at nine thousand five hundred feet. It is at first somewhat open and reminded us of Laguneta. The rich mould of the forest floor was very deep and caused us much anxiety lest some of the pack-animals be lost, for they sank into it to a great depth, and there was constant danger of their floundering and pitching headlong down the mountainside. The arrieros took the utmost precautions, but even then one of the mules became overbalanced and fell off the trail. Fortunately the trees grew close together and one of the packs became wedged between two of them and halted the rolling creature a short distance below. It struggled there with feet in the air until the peons released it and led it back to the trail.
Toward evening we reached a native hut—the second since leaving the valley. The elevation of the place was ten thousand five hundred feet. A large clearing in which white clover grew abundantly surrounded the house. The inhabitants also had other clearings farther down, where they planted corn and wheat. They were all suffering with colds and the dreaded dengue, from which I was fortunately able to give them some relief with the aid of our medical kit. In return for this service they treated us most courteously and placed one of their two rooms at our disposal, although it happened that a score or more of chickens occupied the same quarters. The night was cold and damp. Next morning the wretched people gave us milk and cheese and we purchased several dozen eggs—certainly a great luxury in such an out-of-the-way place. They also showed us the skin and feet of a tapir one of the men had killed in the forest above. The hide had been used to make bottoms for chairs and was of a black color. They reported the presence of two species of bears, one entirely black and the other the tolerably well-known spectacled bear. Although the latter is the only species of bear supposed to exist in South America, I have been told repeatedly by the people that a large black bear is found in the high Andes and have seen skins that appeared to bear out their statements.
After leaving the house next morning we soon reached heavy mountain forest. A deserted hut stood near the border of it, so on our return from the paramo we spent several days there. The chief attraction about the place was the abundance of white-throated sparrows (Brachyspiza capensis capensis). Their cheerful little song cannot fail to endear them to any one with even a limited æsthetic nature. Whether one hears it in the hot, tropical lowlands or on a bleak mountain-top twelve thousand feet above sea-level, the happy little melody is always the same. Nor is the music confined to the hours of daylight only. I have frequently heard it in the darkest hours of night, ringing clear and sweet from somewhere out in the all-pervading blackness. These birds are fond of the proximity of man and are most abundant where he has chosen to break the soil and erect his abode. As a general rule they are not gregarious, but I have seen them congregate in flocks of many thousands to spend the night in some particularly attractive spot in places where sleeping sites were limited in number. Farther south these sparrows also gather in flocks of varying size during the winter season.
The nest is a neat, cup-shaped structure made of fine grasses; it is placed in a low bush or on the ground. Two or three pale-blue eggs thickly spotted with brown are laid and not infrequently two broods are reared in a season.
During our stay at the solitary house on the edge of the great forest a white-throat or chingolo came daily and perched on the bannister of our porch to pour out its overflow of happiness. We grew very much attached to the confiding feathered mite and eagerly awaited its frequent visits. After a short time I discovered the runway of some small rodent under the porch and set a trap to catch the animal. Not long after we heard the dull snap of the spring, and upon investigation found the limp body of the unfortunate songster. The place seemed deserted without the sprightly little bird and we never ceased to miss it.
The belt of forest through which we penetrated before reaching the paramo was magnificent. A species of orchid bearing long spikes of yellow flowers was in full bloom; there were many hundreds of the thick-leaved plants, some perched on lofty branches, others growing from crotches but a few feet above the ground, but all surmounted by a glorious halo of golden blossoms.
We left the forest with its giant moss-covered trees, ensnaring creepers, and breathless silence that suggests a thousand mysteries, at about noon. It ends abruptly and is replaced by a narrow strip of low, dwarfed trees and bushes with small leaves that are either very stiff or are covered with thick down. There were also clumps of blueberry-bushes, but the fruit was woody, bitter and inedible for human beings. Lupines and gentians grew in the hollows and numerous composites thrived on the slopes; among the latter was one with showy purple flowers that the peons called “arnica.”
