The next half-hour was a confused panic, breaking camp, getting Mrs. Thorburn into a canoe, and leaving that accursed place, with a furious energy of terror that could no longer reason. Up-stream, ever up against the swirl of the current the party fought, driven by horror. With no thought of food or drink, paying no heed to landmarks, lashed forward only by the mad desire to be gone, the three men and the girl flung every ounce of their energy into the paddles. Their panting breath mingled with the sound of swirling eddies. A mist-blurred sun brooded over the northern wilds. Unheeded, hosts of black-flies sang high-pitched keenings all about the fugitives. On either hand the forest waited, watched.
