The morning rose fair and bright, with a south-westerly air rather than a breeze. He sailed before it; it was so light that his progress could not have exceeded more than three miles an hour. Hour after hour passed away, and still he followed the line of the shore, now going a short way out to skirt an island, and now nearer it to pass between sandbanks. By noon he was so weary of sitting in the canoe that he ran her ashore, and rested awhile.
It was the very height of the heat of the day when he set forth again, and the wind lighter than in the morning. It had, however, changed a little, and blew now from the west, almost too exactly abaft to suit his craft. He could not make a map while sailing, or observe his position accurately, but it appeared to him that the shore trended towards the south-east, so that he was gradually turning an arc. He supposed from this that he must be approaching the eastern end of the Lake. The water seemed shallower, to judge from the quantity of weeds. Now and then he caught glimpses between the numerous islands of the open Lake, and there, too, the weeds covered the surface in many places.
In an hour or two the breeze increased considerably, and travelling so much quicker, he found it required all his dexterity to steer past the islands and clear the banks upon which he was drifting. Once or twice he grazed the willows that overhung the water, and heard the keel of the canoe drag on the bottom. As much as possible he bore away from the mainland, steering south-east, thinking to find deeper water, and to be free of the islets. He succeeded in the first, but the islets were now so numerous that he could not tell where the open Lake was. The farther the afternoon advanced, the more the breeze freshened, till occasionally, as it blew between the islands, it struck his mast almost with the force of a gale. Felix welcomed the wind, which would enable him to make great progress before evening. If such favouring breezes would continue, he could circumnavigate the waters in a comparatively short time, and might return to Aurora, so far, at least, successful. Hope filled his heart, and he sang to the wind.
The waves could not rise among these islands, which intercepted them before they could roll far enough to gather force, so that he had all the advantage of the gale without its risks. Except a light haze all round the horizon, the sky was perfectly clear, and it was pleasant now the strong current of air cooled the sun’s heat. As he came round the islands he constantly met and disturbed parties of waterfowl, mallards, and coots. Sometimes they merely hid in the weeds, sometimes they rose, and when they did so passed to his rear.
CHAPTER XXII
DISCOVERIES
This little circumstance of the mallards always flying over him and away behind, when flushed, presently made Felix speculate on the cause, and he kept a closer watch. He now saw (what had, indeed, been going on for some time) that there was a ceaseless stream of waterfowl, mallards, ducks, coots, moorhens, and lesser grebes coming towards him, swimming to the westward. As they met him they parted and let him through, or rose and went over. Next he noticed that the small birds on the islands were also travelling in the same direction, that is against the wind. They did not seem in any haste, but flitted from islet to islet, bush to tree, feeding and gossiping as they went; still the movement was distinct.
Finches, linnets, blackbirds, thrushes, wrens, and whitethroats, and many others, all passed him, and he could see the same thing going on to his right and left. Felix became much interested in this migration, all the more singular as it was the nesting-time, and hundreds of these birds must have left their nests with eggs or young behind them. Nothing that he could think of offered an adequate explanation. He imagined he saw shoals of fishes going the same way, but the surface of the water being ruffled, and the canoe sailing rapidly, he could not be certain. About an hour after he first observed the migration the stream of birds ceased suddenly.
There were no waterfowls in the water, and no finches in the bushes. They had evidently all passed. Those in the van of the migratory army were no doubt scattered and thinly distributed, so that he had been meeting the flocks a long while before he suspected it. The nearer he approached their centre the thicker they became, and on getting through that he found a solitude. The weeds were thicker than ever, so that he had constantly to edge away from where he supposed the mainland to lie. But there were no waterfowls and no birds on the islets. Suddenly as he rounded a large island he saw what for the moment he imagined to be a line of white surf, but the next instant he recognised a solid mass, as it were, of swallows and martins flying just over the surface of the water straight towards him. He had no time to notice how far they extended before they had gone by him with a rushing sound. Turning to look back, he saw them continue directly west in the teeth of the wind.
Like the water and the islands, the sky was now cleared of birds, and not a swallow remained. Felix asked himself if he were running into some unknown danger, but he could not conceive any. The only thing that occurred to him was the possibility of the wind rising to a hurricane; that gave him no alarm, because the numerous islands would afford shelter. So complete was the shelter in some places, that as he passed along his sail drew above, while the surface of the water, almost surrounded with bushes and willows, was smooth. No matter to how many quarters of the compass the wind might veer, he should still be able to get under the lee of one or other of the banks.
The sky remained without clouds; there was nothing but a slight haze, which he sometimes fancied looked thicker in front or to the eastward. There was nothing whatever to cause the least uneasiness; on the contrary, his curiosity was aroused, and he was desirous of discovering what it was that had startled the birds. After a while the water became rather more open, with sandbanks instead of islands, so that he could see around him for a considerable distance. By a large bank, behind which the ripple was stilled, he saw a low wave advancing towards him, and moving against the wind. It was followed by two others at short intervals, and though he could not see them, he had no doubt shoals of fishes were passing and had raised the undulations.
The sedges on the sandbanks appeared brown and withered, as if it had been autumn instead of early summer. The flags were brown at the tip, and the aquatic grasses had dwindled. They looked as if they could not grow, and had reached but half their natural height. From the low willows the leaves were dropping, faded and yellow, and the thorn bushes were shrivelled and covered with the white cocoons of caterpillars. The farther he sailed the more desolate the banks seemed, and trees ceased altogether. Even the willows were fewer and stunted, and the highest thorn bush was not above his chest. His vessel was now more exposed to the wind, so that he drove past the banks and scattered islands rapidly, and he noticed that there was not so much as a crow on them. Upturned mussel-shells, glittering in the sunshine, showed where crows had been at work, but there was not one now visible.
Felix thought that the water had lost its clearness and had become thick, which he put down to the action of the wavelets disturbing the sand in the shallows. Ahead the haze, or mist, was now much thicker, and was apparently not over a mile distant. It hid the islands and concealed everything. He expected to enter it immediately, but it receded as he approached. Along the strand of an island he passed there was a dark line like a stain, and in still water under the lee the surface was covered with a floating scum. Felix, on seeing this, at once concluded that he had unknowingly entered a gulf, and had left the main Lake, for the only place he had ever seen scum before was at the extremity of a creek near home, where the water was partly stagnant on a marshy level. The water of the Lake was proverbial for its purity and clearness.
