The storm which had threatened gradually closed in around them, but they held on stubbornly, until, when too far across the bay to put back, it rapidly gathered strength, and soon turned what had been a comparatively safe pathway across the sea into a wilderness of waves, that at one moment rose high above the bow of the canoe, dashing them with spray as the sharp canoe cleaved them, and the next dropped down beneath them, opening a watery trench, into which they plunged. They had seen storms like this, that came quick and sharp upon the lakes, heaving up a sea almost in a moment, with squalls that swept down from the hills. They had been safely through them before; but at those times it had been a short, sharp battle for a half-hour at most, before they could reach a friendly shore. But here it was different. Here were miles of intervening water between them and the nearest land. This was no lake, to be quickly within the shelter of some protecting point of land. But they had never for a moment lost courage nor despaired of coming through all right. They struggled pluckily on, and might have gotten safely to land without mishap, if they had been familiar with the shore of the island. To a stranger, the shore about the head of the island presented a sheer front of forbidding cliffs, rising abruptly from the water, and against which, in a storm, the sea dashed furiously. There was apparently no place at which a boat could be landed; and yet, hidden behind the very barrier of ledge that sheltered it, lay Bryant’s Cove, as quiet and sequestered a pool as any fugitive craft could wish to find. Had the boys known of its existence, they would have landed there, and have been at the Warren cottage before the _Spray_ had left the harbour. As it was, there seemed to them to be no alternative but to keep on to a point about half a mile farther along the shore, where they hoped to be able to make a landing upon the beach. They had accomplished the distance, and were fast nearing a place where they could land in safety, when a most unexpected and disastrous accident happened. Suddenly, and without the slightest warning of its weakness, the paddle which Bob was using snapped in two in his hands. At the same moment a wave hit the canoe, and, with nothing with which to keep his balance, Bob was thrown bodily from the canoe into the sea, upsetting the canoe and spilling Tom out at the same time. The boys were able to grasp the canoe and cling on for a few minutes. They were both good swimmers, and often, in smooth water, had practised swimming, with the canoe upset, and were able to accomplish the feat of righting it, bailing it with a dipper, which they always carried attached to one of the thwarts by a cord, and then climbing aboard over the ends. But it was useless to attempt such a thing in this boisterous sea.
