But at length the work was finished, the craft was taken down to the river, put in the water, and found to float true, and as buoyantly as an egg-shell. The trio therefore put their few belongings into her, not forgetting the two fine emeralds and the gold scales taken from the idol, embarked, and resumed their journey.
They were now on the headwaters of a river which had its rise somewhere on the eastern slope of the Andes; and the water was icy cold, being in fact nothing but the drainings from an enormous glacier which could be seen, some forty miles away, clinging to the side of a majestic peak that towered nearly twenty thousand feet into the deep blue of the tropic sky. But that was a blessing rather than otherwise, for although they were not yet down among the plains the weather was intensely hot—they being now immediately under the equator—and the coldness of the water helped somewhat to mitigate the stifling heat between the two great walls of forest which bordered the river on either hand.
No sail was needed, for they were now travelling with the stream, which, being as yet little more than a mountain torrent, ran rapidly, so that a paddle over the stern to keep the craft in midstream was all that was necessary. But although the stream ran at the rate of fully six miles an hour their progress was not by any means as speedy as one might at first suppose, for rapids occurred at frequent intervals, and if these were found to be impassable it became necessary to carry the canoe past them through the forest. This plan, however, was only resorted to in extreme cases, for if, upon examination, it was deemed at all possible to shoot the rapids, they were shot; and as this sometimes happened as often as three or four times a day, the adventurers soon acquired a degree of dexterity in the art that they would have regarded as perfectly amazing at the beginning of their journey.
On the evening of the fifth day of their journey down the river they chanced to camp at a spot which afforded them an exceptionally fine view of the mountain range to the westward; and when on the following morning they rose to prepare for the day’s journey they saw that a terrific thunderstorm was raging about halfway up the eastern slope of the range. It was a magnificent sight, the clouds, black as night below, but brilliantly illuminated by the sun above, clinging to the mountain spurs in enormous masses which rolled together, parted, and rolled together again like charging squadrons, while the lightning, keen and vivid as molten steel, incessantly darted from their black breasts like the flashes of a platoon of musketry. And while this elemental warfare was raging furiously up there among the mountains it was brilliant weather where the wanderers were camped, with not a breath of wind to assuage the torrid heat. Stukely happened to make some remark upon the contrast to Vilcamapata, to which the old man replied:
“Yes, it is well for us that we are here rather than there; for such a storm might well mean death for us all. But we must be watchful to-day, lord, for that storm covers many miles of country, and the rain is falling in torrents; and, unless I am greatly mistaken, most of it will find its way into this river. Therefore must we be on our guard against a sudden spate, which may overwhelm us if we are caught unawares.”
The Englishmen agreed, and nothing further was said about the matter, for they were busy making their preparations for the day; and in due time they embarked and proceeded on their journey. About midday, in confirmation of the old Peruvian’s words, the first of the expected spate revealed itself in a sudden acceleration of the current and a change in the appearance of the water, which became turbid with mud in suspension. Yet although the speed of the current continued to increase gradually, it merely helped the voyagers on their way, for they now seemed to have reached a stretch of the river that was entirely free from rapids, nothing of the kind having been encountered since their start in the early morning. Swiftly the canoe sped down the river, running now at the rate of a good nine miles an hour, and her occupants rejoiced exceedingly, for they were getting over as much ground in a single hour as sometimes cost them a whole day to cover. They began to make light of the precautions which they had observed during the earlier hours of the day, and told each other with glee that if this was the worst a spate could do they would welcome one every day so long as they were bound downstream.
Indeed it was speedy travelling compared with what they had been accustomed to; it was like journeying by postchaise after travelling in a market wagon. The country swept past them at a speed that almost made them giddy as they watched it, while the motion of the canoe was smooth and easy as that of a cradle. Then, as they whirled round a bend they suddenly, and without warning, found themselves sweeping through a gorge with vertical, rocky, fern-grown banks on either hand. Too well they knew what that sort of thing was the prelude to. There were rapids ahead, almost to a dead certainty, and they had missed their chance of inspecting before attempting to shoot them, for there was no landing on either of those vertical banks; while as for returning to a point where landing was possible, they might as well have attempted to fly! Well, there was but one thing for it; if there were indeed rapids ahead they must do their best to shoot them without the usual preliminary inspection; they were growing quite accustomed to that kind of work now, and it ought not to be so very difficult.
Accordingly Dick placed himself in the bow of the canoe and Phil stationed himself amidships, each armed with the long pole which they used to bear the canoe off the rocks when shooting rapids, while the Peruvian perched himself up in the stern with the short steering paddle in his hand. Presently the expected rapids swung into view ahead, and a sufficiently formidable sight they presented. It was difficult, nay impossible, to tell how far they extended, for a bend of the river shut out the view; but there was at least half a mile of them in plain sight, a narrow channel of foaming, leaping water, with the black head of a rock showing occasionally here and there amid the foam. Dick drew his feet up under him and raised himself to his full height in the crank cockleshell of a canoe, in order that he might obtain as extended a view as possible of what lay before him: he was admittedly far the more expert canoeist of the two, especially when it came to shooting rapids, therefore on such occasions his post was always in the bow, which then becomes the post of honour—and of responsibility.
What he saw was by no means reassuring; there was far too much spouting and foaming water for his taste, for such appearances invariably indicated rocks submerged to the extent of a few inches at the utmost, contact with any of which meant at least the destruction of the canoe, if no worse mishap. True, in almost every stretch of rapids there exists what may be termed by courtesy a channel, that is to say, there is a passage, more or less tortuous, between the rocks where the water is deep enough to float a canoe if one can but hit it off in time. This channel or passage is usually distinguishable by the comparative smoothness of the water in it; so that if the navigator can guide his canoe fairly into it by the time that the rapids are actually reached, he stands a very fair chance of accomplishing the run in safety, although even then he must be continually on the alert, since the turns are often so sharp that, unless taken at precisely the right moment, the canoe may be dashed with destructive violence against an obstructing rock; and it was the part of the bowman, or pilot, to look out for such rocks and bear the canoe off them with the long pole which he invariably wielded.
At length Dick believed he saw the beginning of such a channel, close under the right bank of the river, and waved Vilcamapata to steer the canoe toward it. Half a minute more, and the little craft had darted in between two formidable walls of leaping water and was speeding downward at a speed of fully fifteen miles an hour, with Dick and Phil standing upright and thrusting their long poles first to one side and then the other as Chichester’s experienced eye detected the signs which mark the presence of dangerous rocks to right or left, and signalled accordingly. To cry out was utterly useless, the roar and hiss of the tortured waters was far too loud to render even the voice of a Stentor audible, and those behind the pilot could but watch his motions, and act accordingly.
