Above the splash of the oars and the swift rush of the river rose a sound like the far roar of street traffic.

"Our little vacation is over," commented Forrester.

"Easy now, Forr! We'll land for observation before we tackle a racket like that. Let the current carry us. Be ready to back water when I shout." He raised his voice. "Harden, don't follow too closely! You know your failing!"

They rounded a curving wall, the current carrying them, Milton said, at least ten miles an hour. A short distance now, and they saw spray breaking high in the middle of the stream.

"We'll land here," said Milton, steering to a great pile of bowlders against the right wall.

Enoch watched with keen interest the preparation for the descent. First sticks were thrown into the water, to catch the trend of the main current. Milton pointed out to Enoch that if the stick were deflected against one wall or another, great care had to be exercised to prevent the boats being dashed against the walls in like manner. But, he said, if the current seemed to run a fairly unobstructed course, it was hopeful that the boats would go through. There were a number of rocks protruding from the water, but the current appeared to round these cleanly and Milton gave the order to proceed. They worked back upstream a short distance so as to catch the current straight prow on, and in a moment they were dashing through a sea of roaring waves that drenched them to the skin.

Forrester and Milton steered a zigzag course about the menacing rocks, grazing and bumping them now and again, but emerging finally, without accident, in quieter waters. Here they hugged the shore and waited for Harden's boat, the Mary, to come down. And come it did, balancing uncannily on the top of the waves, with Jonas' yells sounding even above the uproar of the waters.

"More of it below, Harden," said Milton as the Mary shot alongside.

More indeed! It seemed to Enoch that the first rapid was child's play to the one that followed. The jutting rocks were more frequent. The fall greater. The waves more menacing. But they shot it safely until they reached its foot and there an eddy caught them and carried them back upstream in spite of all that could be done. Enoch seized the oars that were in readiness beside him and pulled with all his might but to no avail. And suddenly the Mary rushed out of the mist striking them fairly amidship. The Ida half turned over, but righted herself and the Mary darted off. Milton shouted hoarsely, Forrester and Enoch obeyed blindly and after what seemed to Enoch an endless struggle, spray and waves suddenly ceased and they found themselves in quieter waters where the Mary awaited them.

Harden and Agnew were laughing. "Thought you knew an eddy when you saw one, Milt!" cried Agnew.
