Hal forgot his momentary anxiety; Pepe rowed on, leisurely; and George lounged in his seat. There was no menace for them in that dull, continuous roar.

But Ken knew they would soon be in fast water and before long would drop down into the real wilderness. It was not now too late to go back up the river, but soon that would be impossible. Keeping a sharp lookout ahead, Ken revolved in mind the necessity for caution and skilful handling of the boat. But he realized, too, that overzealousness on the side of caution was a worse thing for such a trip than sheer recklessness. Good judgment in looking over rapids, a quick eye to pick the best channel, then a daring spirit--that was the ideal to be striven for in going down swift rivers.

Presently Ken saw a break in the level surface of the water. He took Pepe's place at the oars, and, as usual, turned the boat stern first down-stream. The banks were low and shelved out in rocky points. This relieved Ken, for he saw that he could land just above the falls. What he feared was a narrow gorge impossible to portage round or go through. As the boat approached the break the roar seemed to divide itself, hollow and shallow near at hand, rushing and heavy farther on.

Ken rowed close to the bank and landed on the first strip of rock. He got out and, walking along this ledge, soon reached the fall. It was a straight drop of some twelve or fifteen feet. The water was shallow all the way across.

"Boys, this is easy," said Ken. "We'll pack the outfit round the fall, and slide the boat over."

But Ken did not say anything about the white water extending below the fall as far as he could see. From here came the sullen roar that had worried him.

Portaging the supplies around that place turned out to be far from easy. The portage was not long nor rugged, but the cracked, water-worn, rock made going very difficult. The boys often stumbled. Pepe fell and broke open a box, and almost broke his leg. Ken had a hard knock. Then, when it came to carrying the trunk, one at each corner, progress was laborious and annoying. Full two hours were lost in transporting the outfit around the fall.

Below there was a wide, shelving apron, over which the water ran a foot or so in depth. Ken stationed Pepe and the boys there, and went up to get the boat. He waded out with it. Ken saw that his end of this business was going to be simple enough, but he had doubts as to what would happen to the boys.

"Brace yourselves, now," he yelled. "When I drop her over she'll come a-humming. Hang on if she drags you a mile!"

Wading out deeper Ken let the boat swing down with the current till the stern projected over the fall. He had trouble in keeping his footing, for the rock was slippery. Then with a yell he ran the stern far out over the drop, bore down hard on the bow, and shoved off.
