"Is falling down a well your idea of fun?" asked Harry.

"It's too soon," said Charley, "to decide who has the best canoe. We'll find that out by the time the cruise is over."

The island where the boys camped during their first night on the St. Lawrence was situated at the head of Lake St. Peter. This lake is simply an expansion of the St. Lawrence, and though it is thirty miles long, and about ten miles wide at its widest part, it is so shallow that steamboats can only pass through it by following an artificial channel dredged out by the government at a vast expense. Its shores are lined with a thick growth of reeds, which extend in many places fully a mile into the lake, and are absolutely impassable, except where streams flowing into the lake have kept channels open through the reeds.

On leaving the island in the morning the canoeists paddled down the lake, for there was not a breath of wind. The sun was intensely hot, and the heat reflected from the surface of the water and the varnished decks of the canoes assisted in making the boys feel as if they were roasting before a fire. Toward noon the heat became really intolerable, and the Commodore gave the order to paddle over to the north shore in search of shade.

It was disappointing to find instead of a shady shore an impenetrable barrier of reeds. After resting a little while in the canoes, the boys started to skirt the reeds, in hope of finding an opening; and the sun, apparently taking pity on them, went under a cloud, so that they paddled a mile or two in comparative comfort.

The friendly cloud was followed before long by a mass of thick black clouds coming up from the south. Soon the thunder was heard in the distance, and it dawned upon the tired boys that they were about to have a thunder-storm without any opportunity of obtaining shelter.

They paddled steadily on, looking in vain for a path through the reeds, and making up their minds to a good wetting. They found, however, that the rain did not come alone. With it came a fierce gust of wind, which quickly raised white-caps on the lake. Instead of dying out as soon as the rain fell, the wind blew harder and harder, and in the course of half an hour there was a heavy sea running.

The wind and sea coming from the south, while the canoes were steering east, placed the boys in a very dangerous position. The seas struck the canoes on the side and broke over them, and in spite of the aprons, which to some extent protected the cockpits of all except the Twilight, the water found its way below. It was soon no longer possible to continue in the trough of the sea, and the canoes were compelled to turn their bows to the wind and sea, the boys paddling just sufficiently to keep themselves from drifting back into the reeds.

The Sunshine and the Midnight behaved admirably, taking very little water over their decks. The Twilight "slapped" heavily, and threw showers of spray over herself, while the Dawn showed a tendency to dive bodily into the seas, and several times the whole of her forward of the cockpit was under the water.

"What had we better do?" asked Harry, who, although Commodore, had the good sense always to consult Charley in matters of seamanship.
