“The sun is up. Rouse, my master! It is time we were on the road,” replied the Indian.
“I feel very drowsy—I am heavy—I can scarce keep my eyes open. What can be the cause of this?”
“The poison-trees, master,” answered Guapo.
The answer seemed to impress Don Pablo. He made a violent effort, and rose to his feet. When up he could scarcely stand. He felt as though he had swallowed a powerful opiate.
“It must be so, good Guapo. Perhaps there is some truth in what you have said. O, heavens!” exclaimed he, suddenly recollecting himself,—“the others—my wife and children!”
This thought had fully awakened Don Pablo; and Guapo and he proceeded at once to arouse the others, which they effected after much shouting and shaking. All were still heavy with sleep, and felt as did Don Pablo himself.
“Surely there is some narcotic power in the aroma of these trees,” muttered Don Pablo. “Come, wife, let us be gone! We must remain under its influence no longer, else what Guapo has said may prove too true. Saddle up—we must eat our breakfasts farther on. To the road!—to the road!”
Guapo soon had the horses ready, and all hurried from the spot, and were once more climbing up the mountain-path. Even the animals seemed to move slowly and lazily, as though they, too, had been under the influence of some soporific. But the pure cold air of the mountain soon produced its effect. All gradually recovered, and after cooking some charqui and ocas in the ravine, and making their breakfast upon these, they again felt light and fresh, and pursued their journey with renewed vigour.
The road kept on up the ravine, and in some places the banks rose almost perpendicularly from the bed of the dry torrent, presenting on both sides vast walls of black porphyry—for this is the principal rock composing the giant chain of the Andes. Above their heads screamed small parrots of rich plumage of the species Conurus rupicola, which make their nestling places, and dwell upon these rocky cliffs. This is a singular fact, as all other parrots known are dwellers among trees and are found in the forest at all times, except when on their passage from place to place.
But even the squirrel, which is an animal peculiarly delighting in tree-life, has its representative in several species of ground-squirrels, that never ascend a tree; and, among the monkeys, there exists the troglodyte or cave-dwelling chimpanzee. No doubt squirrels or monkeys of any kind, transported to an open or treeless country, would soon habituate themselves to their new situation,—for Nature affords many illustrations of this power of adaptation on the part of her creatures.
