“I hope so,” was the reply of the tapuyo, given with no great confidence.
Trevannion reflected that they had been swimming in a circle. Should this occur again,—and there was every possibility of such a thing,—the desired end might not be so easy of accomplishment.
For some minutes speculation was suspended. The guide was engaged in action. Like a water-spaniel in search of a winged wild-duck, he repeatedly reared himself above the surface, casting glances of interrogation to every quarter of the compass. Like the same spaniel, when convinced that the wounded bird has escaped him, he at length desisted from these idle efforts; and, laying his body along the water, prepared to swim disappointedly to the shore.
With something more than disappointment—something more than chagrin—did Munday commence retreating from the lagoon. As he called upon his companions to follow him, there was a tremor in his voice, and an irresolution in his stroke perceptible to the least observant of them; and the fact of his having shouldered the dead guariba, after first making inspection to see that it was fit for food, was proof of his entertaining some suspicion that their voyage might be a long one. No one questioned him; for notwithstanding the failure of his promise to guide them straight across the lagoon, they still relied upon him. On whom or what else could they rely?
After proceeding a considerable distance, he came to a pause, once more stood up in the water, and, turning as upon a pivot, scanned the circle of the horizon. Satisfied that there was not a tree-top within view, he swam onward as before. Could he have ensured keeping a straight course, no great danger need have been apprehended. The lagoon might be ten miles wide; or, if twenty, it could not so materially affect the result. Swim as slowly as they might, a score of hours would see them on its shore,—whether this was the spray of another submerged forest, or the true terra firma. There was no danger of their going to the bottom, for their swimming-belts secured them against that. There was no danger of their suffering from thirst,—the contingency most dreaded by the castaway at sea, and the strayed traveller in the desert,—of fresh water they had a surfeit. Nor did hunger dismay them. Since eating the jacana, they had set forth upon a breakfast of Brazil-nuts,—a food which, from its oily nature, may be said to combine both animal and vegetable substance. Moreover, they were now no longer unprovided against a future emergency: since their guide carried upon his shoulders the carcass of the guariba.
Their real danger lay in their deviating from a right line: for who could swim straight, with his eyes on a level with the surface of the water, and nothing to direct his course, neither tree, nor rock, nor star, nor signal of any kind? The tapuyo knew this. So did they all. Even the children could tell that they were no longer guided, but going by guess-work. It was no longer a question of getting across the lagoon, but out of it. The unsteady movements of their guide, instead of allaying their fears, produced the contrary effect, and the disconsolate expression on his countenance was evidence that he was under much apprehension.
For over an hour this uncertainty continued. The swimmers, one and all, were beginning to give way to serious alarm. To say nothing of reaching land, they might never more set eyes upon the submerged forest. They might swim round and round, as in the vortex of Charybdis, until sheer exhaustion should reduce them utterly. In due time hunger must overtake them; and a lingering death by starvation might be their destiny. When faint from want of food and unable to defend themselves, they would be attacked by predatory creatures dwelling in the water, while birds of prey would assail them from the air. Already could they fancy that the cry of the caracara sounded more spiteful than was its wont; and exultingly, as if the base bird foreboded for them a tragical ending.
More than twenty times had the tapuyo repeated his inspection of the horizon, without seeing aught to cheer him. They had been many hours in the water, and supposed it to be about noon. They could only conjecture as to the time, for the sun was not visible. At an early hour in the morning—almost as they started—the sky had become overcast with a sheet of leaden grey, concealing the sun’s disk from their sight. This circumstance had caused some discouragement; but for it they might long since have escaped from their dilemma, as the golden luminary, while low down, would have served them as a guide.
Strange to say, at that hour when it was no longer of any concern to them, the sky became suddenly clear, and the sun shone forth with burning brilliance. But his orb was now in the zenith, and of no service to point out the quarter of the compass. Within the equatorial zone, north, south, east, and west were all alike to him at that season of the year and that hour of the day. If they could but have the direction of one of these points, all would have been well. But the sun gave no sign.
For all that, the Indian hailed his appearance with a grunt of satisfaction, while a change came over his countenance that could scarce be caused by the mere brightening of the sky. Something more than cheerfulness declared itself in his dark features,—an expression of renewed hope.
