As for Joe and Tom, the mosquitoes fell upon them with great enthusiasm, and soon reduced them to a most miserable condition. Tom was compelled to cover his head with his India-rubber blanket, and was nearly suffocated. Joe managed to tie a handkerchief over his face in such a way as to allow himself air enough to breathe, and at the same time to keep off the mosquitoes. Instead of covering the rest of his body with his blanket, he deliberately exposed a bare arm and part of a bare leg, in hopes that he could thus satisfy the mosquitoes, and induce them to be merciful. At the end of half an hour both Tom and Joe felt that they could endure the attacks of the dreadful insects no longer. They got up, and stirring the embers of the fire, soon started a cheerful blaze. There were plenty of hemlock-trees close at hand, and the hemlock boughs when thrown on the fire gave out a great deal of smoke. The two unfortunate boys sat in the lee of the fire and nearly choked themselves with smoke; but they could endure the smoke better than the mosquitoes, and so they were left alone by the latter.

GETTING BREAKFAST UNDER DIFFICULTIES.

The wind died down before morning, and the mosquitoes returned. As soon as it was light the canoeists made haste to get breakfast and to paddle out into the stream. The mosquitoes let them depart without attempting to follow them; and the boys, anchoring the canoes by making the ballast bags fast to the painters, enjoyed an unmolested bath. As they were careful to anchor where the water was not four feet deep, they had no difficulty in climbing into the canoes after the bath. Joe's mishap on Lake Memphremagog had taught them that getting into a canoe in deep water was easier in theory than in practice.

Later in the morning the usual southerly breeze, which is found almost every morning on the Richelieu, gave the canoeists the opportunity of making sail. The breeze was just fresh enough to make it prudent for the canoes to carry their mainsails only, and to give the canoeists plenty of employment in watching the gusts that came through the openings in the woods that lined the western shore.

About twelve miles below Rouse's Point the fleet reached "Ile aux Noix," a beautiful island in the middle of the stream, with a somewhat dilapidated fort at its northern end. The boys landed, and examined the fort and the ruined barracks which stood near it. The ditch surrounding the fort was half filled with the wooden palisades which had rotted and fallen into it, and large trees had sprung up on the grassy slope of the outer wall. The interior was, however, in good repair, and in one of the granite casemates lived an Irishman and his wife, who were the entire garrison. In former years the "Ile aux Noix" fort was one of the most important defenses of the Canadian frontier, and even in its present forlorn condition it could be defended much longer than could the big American fort at Rouse's Point. The boys greatly enjoyed their visit to the island, and after lunch set sail, determined to make the most of the fair wind, and to reach St. John before night.

The breeze held, and in less than three hours the steeples and the railway bridge of St. John came in view. The canoeists landed at the upper end of the town, and Harry and Charley, leaving the canoes in charge of the other boys, went in search of the Custom-house officer whose duty it was to inspect all vessels passing from the United States into Canada by way of the Richelieu River. Having found the officer, who was a very pleasant man, and who gave the fleet permission to proceed on its way without searching the canoes for smuggled goods, Harry and Charley walked on to examine the rapids, which begin just below the railway bridge. From St. John to Chambly, a distance of twelve miles, the river makes a rapid descent, and is entirely unnavigable for anything except canoes.

The first rapid was a short but rough one. Still, it was no worse than the first of the Magog rapids, and Harry and Charley made up their minds that it could be safely run. The men of whom they made inquiries as to the rapids farther down said that they were impassable, and that the canoes had better pass directly into the canal, without attempting to run even the first rapid. Harry was inclined to think that this advice was good, but Charley pointed out that it would be possible to drag the canoes up the bank of the river, and launch them in the canal at any point between St. John and Chambly, and that it would be time enough to abandon the river when it should really prove to be impassable.

Returning to the canoes, the Commodore gave the order to prepare to run the rapids. In a short time the fleet, with the Sunshine in advance, passed under the bridge, and narrowly escaping shipwreck on the remains of the wooden piles that once supported a bridge that had been destroyed by fire, entered the rapid. There was quite a crowd gathered to watch the canoes as they passed, but those people who wanted the excitement of seeing the canoes wrecked were disappointed. Not a drop of water found its way into the cockpit of a single canoe; and though there was an ugly rock near the end of the rapid, against which each canoeist fully expected to be driven as he approached it, the run was made without the slightest accident.

Drifting down with the current a mile or two below the town, the boys landed and encamped for the night. While waiting at St. John, Joe and Tom had provided themselves with mosquito netting, but they had little use for it, for only a few mosquitoes made the discovery that four healthy and attractive boys were within reach. The night was cool and quiet, and the canoeists, tired with their long day's work, slept until late in the morning.
