Chapter Thirty Eight.
A Cul-de-Sac.
Notwithstanding the pleasant theme that formed the subject of their after-dinner discourse, it was not long continued. Both those who took part in it and those who listened were too anxious about their situation to enjoy even the most interesting conversation. As soon, therefore, as they felt sufficiently recruited by the rest, they resumed their aquatic journey. For several hours they continued to advance at the same slow rate, without encountering any incident worthy of record. The igarápe still trended in a straight line, with only here and there a slight turning to one side or the other, preserving, however, the same general direction, which was northward. This they had discovered on the night before, not by observing the polar star, which is at no time visible at the equator, nor until you have travelled several degrees to the north of it. Even when this well-known star should be seen from the low latitudes of the torrid zone, it is usually obscured by the hazy film extending along the horizon. Sirius and other northern, constellations had guided them. As the sun had been shining throughout the whole of that day as well as the preceding one, you may suppose there could be no difficulty in discovering the quarter, within a point or two of the compass, at any hour of the day. This might be true to any one travelling in a high latitude, northern or southern, or at certain seasons of the year, anywhere outside the tropics. Even within the tropics it might be done by skilful observation, if the observer knew the exact time of the year. Trevannion knew the time. He knew, moreover, that it was close upon the vernal equinox, when the sun was crossing the equatorial line, near to which they were wandering. For this reason, in the meridian hours the great orb was right over their heads, and no one—not even a skilled astronomer—could have told north from south, or cast from west.
Supposing that the igarápe should not be trending in the same direction, but imperceptibly departing from it? In that case, during the mid-hours of the day they could have had no guidance from the sky, and must have suspended their journey till the sun should begin to sink towards the west, and once more make known the points of the compass. Fortunately they needed not to make this delay. As already observed, the flow of the flood was the pilot to which they looked for keeping them in their course; and, as this still ran with a slight obliquity in the same direction as the igarápe, the latter could not have departed from the right line upon which, they had been advancing. The current had been compared with the points of the compass that morning before setting out. It was a little to the east of north. Northward, then, was the course of the swimmers.
They had drawn further inference from the direction in which the flood was setting. It proved that they had strayed from the Solimoës by its left or northern bank, and must now be somewhere among the mouths of the great river Japura. It was no consolation to discover this, but the contrary. The old tapuyo only looked graver on arriving at the conviction that such was the case. He knew that in that direction, in the vast delta formed by the unnumbered branches of the Japura, the Gapo was of great width, extending far back from the banks of this remarkable river, and dry land in that direction might be at the greatest distance. There was no alternative but to keep on, and, by deviating from the course as little as possible, they might in due time reach the limits of the flood. Actuated by this impulse and its attendant hopes, they continued their toilsome journey along “the path of the canoe.”
We have said that for several hours they encountered no incident worthy of note. It was not destined, however, for that day’s sun to set before one should arise, whose record is not a matter of choice, but necessity, since it exerted such an influence on the proceedings of the travellers as to cause a complete change in their mode of progression. What they encountered was not exactly an incident, but an obstruction. In other words, their swim was suddenly brought to an end by the ending of the igarápe!
They had arrived at the termination of this curious canal, which all at once came to a cul-de-sac, the trees closing in on both sides, and presenting an impenetrable front, that forbade farther progress. The way was equally obstructed in every other direction; for on neither side of the igarápe, throughout its whole length, had any opening been observed. At first they fancied that the water might open again beyond the obstruction, but Munday, after penetrating a short distance among the tree-trunks, returned to declare his conviction that the igarápe was at an end. Nor did it terminate by any gradual convergence of the two lines of trees. On the contrary, they came together in an abrupt circular sweep,—one of colossal size, that rose high above its fellows and spread far out, standing in the centre, like some Titanic guardian of the forest, and seeming to say to the igarápe, “Hitherto shalt thou come, but no farther!”
It was of no use remaining longer in the water for that day. Even had the obstruction not arisen, it was time to have suspended their exertions. The sun was sinking towards the tree-tops, and by the time they could get themselves snugly stowed away, and something ready for supper, it would be night. Leaving other cares for the morrow, and the morrow to take care of itself, they at once proceeded to select their sleeping-place for the night. The colossal tree that had come so unpleasantly across their track seemed to offer the very quarters they were in search of; and, without more ado, they accepted the hospitality of its wide-spreading branches.
