It was a glorious morning. A fresh, bracing wind blew from the south. The cloud-flecked mountains loomed sharp and blue around the lake, and the great range on the western shore was especially grand and imposing. David discovered beneath one of its glaciers, several thousand feet above the lake, what appeared to be a yawning cave as big as a house, and the captain's glass brought it out more distinctly. Here was a natural wonder fairly begging to be visited, and right well would David have liked to explore its mysteries; but time was precious to the voyagers, and they held their course steadily to the north, crossing the mouth of a great bay which extended several miles eastward. There was a similar bay to the west, but the lake narrowed again as they approached the outlet. At noon they landed for dinner in a little cove, which they named Shelter Bay, and there, the wind deserting them, they had recourse to the oars and rowed the short distance to the river, after which the current assisted them. The water was here so clear that they could see the fish as they darted away from the shadow of the oars. Several yellow-legged plover were shot along the banks, but no attempt was made to bag ducks, as it was their breeding season.

Early in the evening they reached the sandy bluff near Pennock's cabin and moored the boat to a tree. The cabin was now deserted by human beings, but when David opened the door a fat ground-squirrel scurried across the floor and ran out through a hole under the side log. It seemed too bad that such a stanch dwelling should be given over to neglect, but such is often the case in a new country. The travellers did not sleep in it, for the mosquitoes were in possession. They pitched their insect-proof tents by the side of the river and passed the night in comfort.

But before they turned in, Champlain and David took trout flies and lines and sauntered down the stream to try to discover what kind of fish they had seen. They cut rude willow poles and fished carefully but in vain until they came to the mouth of Frying-Pan Creek. Here the current of the brook cleared for a space the now muddy river water, and Champlain had a rise almost immediately. A few seconds later he landed a delicately spotted, gamy fish about eight inches long, which he recognized as a grayling. The sport became exciting at once, and David soon had half a dozen catches to his credit. When the anglers could no longer induce a rise, they marched back to camp in triumph with a handsome string.

The voyage was continued next day. Champlain entertained his companions with an account of his successful moose-hunt a few weeks previous, which had relieved the hunger of the northernmost party of the Thirty-six. Then he told of the difficulties he and others had overcome in rafting the goods from their great cache and Pennock's Post down to the Landing. He had shot an otter on one of his journeys along the stream, but said he had seen hardly a trace of beavers.

The river now became extremely tortuous. Greenwood wondered how it could make so many loops without tying itself into a knot, and expressed a decided preference for walking as a means of getting to the Landing. As he was taking his turn at rowing at that moment, it was easy to account for his sudden feeling in the matter.

By skilful use of helm and paddle Champlain guided the boat through a number of rocky stretches in safety, but he was not to be invariably so successful. David, who had been intently gazing forward, suddenly shouted a warning. Five or six boulders lay in the stream so nearly submerged that they could hardly be discerned from a distance, while others just below the surface betrayed their position only by eddies. Champlain put all his strength into the paddle, but in that current the heavy boat could be swerved but little. A dangerous eddy was barely avoided, but beyond and directly in their path a ragged rock appeared. How the paddle flashed! And how the rowers struggled! But in a moment it was evident that the boat must strike.

Crunch! went her side against the rock. She careened as she stopped, and the current piled up against her, while her passengers fully expected shipwreck and instinctively measured the distance to the shore. But the force of the stream, instead of swamping the stout little craft, swept her past the obstruction, and all breathed freely once more. By great good fortune not the least damage had been sustained.

Early in the afternoon they passed between Father and Son, otherwise known as Mount Champlain and Mount Bratnober respectively. The pass was about a mile wide, with perpendicular cliffs several thousand feet high on either side. In this wild place they found the forest recently burned, and in one spot near the base of Mount Bratnober smoke was still rising. It was this great conflagration, covering thousands of acres, which had filled the atmosphere with smoke a few weeks before and caused the sun to look like a blood-red ball as it sank in the west. Champlain related how, in company with a Canadian government surveyor, he had climbed the mountain which had received his name. He was sure they could have seen Mount St. Elias in the west had not clouds obscured the view. They noticed a flock of mountain sheep, but did not get near enough for a shot.

The voyage was presently enlivened by a race with a brood of little ducks which Mother Mallard had taken out for an airing,—or "watering," as David put it. There were a dozen of the little fellows not two weeks out of the shell, and what a splashing they set up when they saw the strange, oared craft bearing down upon them! The mother duck quacked anxiously from the rear of her flotilla and urged the youngsters forward at the top of their speed, which proved just about equal to that of the boat.

The little ducks could not fly, and the river was so narrow that at first they dared not swerve toward either shore, but flapped and paddled and splashed straight down the river. Not until they became utterly exhausted did they seek the bank. Then one by one, as a convenient log or hole appeared, they dropped away from the others and hid themselves while the terrible monster went by. The old duck paid not the slightest attention to these stragglers, but continued with that part of her brood which was still in danger, turning her head from side to side and talking vigorously in duck language to her terrified children.
