The forenoon of the first day was comparatively easy going, though there were places enough for an amateur to wreck; but the real battle with the river began at the Pine Creek Rapids—the battle that no experienced boatman ever was rash enough to prophesy the result. The sinister stream, with its rapids and whirlpools, its waterfalls and dangerous channel-rocks, had claimed countless victims in the old days of the gold rush and there were years together since the white people had settled at Meadows that no boat had gone even a third of its length. Wherever the name of the river was known its ill-fame went with it, and those feared it most who knew it best. Only the inexperienced, those too unfamiliar with water to recognize its perils so long as nothing happened, spoke lightly of its dangers.

Above the Pine Creek Rapids, Bruce swung into an eddy to tie up for lunch; besides, he wanted to see how Smaltz handled his sweep. Smaltz came on, grinning, and Porcupine Jim, bare-headed, his yellow pompadour shining in the sun like corn-silk, responded instantly to every order with a stroke. They were working together perfectly, Bruce noted with relief, and the landing Smaltz made in the eddy was quite as good as the one he had made himself.

Once more Bruce had to admit that if Smaltz boasted he always made good his boast. He believed there was little doubt but that he was equal to the work.

An ominous roar was coming from the rapids, a continuous rumble like thunder far back in the hills. It was not the most cheerful sound by which to eat and the meal was brief. The gravity of the boatmen who knew the river was contagious and the grin faded gradually from Smaltz’s face.

Life preservers were dragged out within easy reach, the sweepmen replaced their boots with rubber-soled canvas ties and cleared their platform of every nail and splinter. When all were ready, Bruce swung off his hat and laid both hands upon his sweep.

“Throw off the lines,” he said quietly and his black eyes took on a steady shine.

There was something creepy, portentous, in the seemingly deliberate quietness with which the boat crept from the still water of the eddy toward the channel.

The bailer in the stern changed color and no one spoke. There was an occasional ripple against the side of the boat but save for that distant roar no other sound broke the strained stillness. Bruce crouched over his sweep like some huge cat, a cougar waiting to grapple with an enemy as wily and as formidable as himself. The boat slipped forward with a kind of stealth and then the current caught it.

Faster it moved, then faster and faster. The rocks and bushes at the water’s edge flew by. The sound was now a steady boom! boom! growing louder with every heart-beat, until it was like the indescribable roar of a cloudburst in a canyon—an avalanche of water dropping from a great height.
