Slowly the bow of the canoe crept up to a spot where the keen eyes of Henry Burns had noted the sunken ledge, at a point only a rod from the upper incline. This ledge did not show above water, but the boiling of the stream and an almost imperceptible sloping of the surface on either hand showed that it was there.

Henry Burns leaned over the side of the canoe and gazed anxiously. Should the water there prove deeper than he had hoped, they would not ground, and must be carried back, their strength exhausted. But he had not been mistaken.

In a moment the water suddenly shallowed. A hard thrust with the paddles, and the canoe grated gently.

"Easy, Jack," cried Henry Burns. "She's hit. Get out the pole."

Harvey seized the setting-pole from the bottom of the canoe, dropping his paddle in its place. He thrust it quick and with all his strength into the swift-running water. At a depth of about three feet it caught the rocky bottom and held. Harvey braced with the pole and shoved the bow of the canoe, which had touched on the part of the ledge that was close to the surface, a little farther ahead.

"Great!" shouted Henry Burns. "Take it easy now. She'll stay if the pole don't slip."

Harvey relaxed his exertions, holding the pole at an angle sufficient to keep the canoe where it was, with only slight pressure. Henry Burns, dropping his own paddle and likewise taking up his setting-pole, got a grip in the rocks and aided his companion. They could rest now, with the swift water rushing past them on either bow, and recover their wind and strength for the final struggle.

Their plan was, when they should have rested, to let the canoe drop back about a foot, enough to clear the sunken ledge; then, before the current should catch them, to shove out into it quickly, turn the bow of the canoe to meet the rush of the rapids, and push over with the poles, by main strength. They could do it, if, as Henry Burns expressed it, the canoe "did not get away from them."

The five minutes they waited seemed like hours. Away up along the carry, they could see the Ellison brothers, lifting their canoe across the broken bits of shore; Tom and Bob some way behind these, hurrying as fast as they dared over the treacherous footing. But now, as they gathered their strength, and gently shoved their canoe back, a cry from Tom, who had noted their move, arrested the progress of the Ellison boys. They paused for a moment and, with Tom and Bob, watched the outcome, eagerly.

Alas! it was sharp and bitter for Henry Burns. The canoe hung for a moment, as they arrested its drifting with strong thrusts of the poles. Then it shot ahead, as they pushed its nose diagonally out into the sharp slope of the rapids. Henry Burns thrust his pole down hard, as they cleared the sunken ledge, to swing the bow straight into the current. But the bottom proved treacherous.
