"Help!" rang out one choked-off cry, as in a great rush of suddenly foaming flood, over the dam plunged a boat and a terrorized boy.

CHAPTER II

A HOPELESS SEARCH

In the brief instant that Jerry stood on the slippery point of rock he had the queer feeling that it was all a horrible dream, or at least only an impossible scene from a motion picture. Where a boat had been a second before was now only a seething, tossing down-tumbling wall of brownish foam.

But his stunned inaction was quickly gone. Down to the very edge of the flood he raced, almost losing his balance and toppling in. At a dangerous angle he leaned over and peered into the churning water-pit below.

Dave had come hurrying to his side, to miss his footing at the last and plunge waist-deep into the current. A precious moment was lost in rescuing him. When, both safe on the rocky ledge, they turned to scan the depths of the fall, it was to see a dark object suddenly pop up full fifty feet downstream. It was the boat—but no Tod.

"Did you see it!" cried Jerry excitedly. "Didn't it look like something blackish in the bottom of the boat?"

"She's full of water, that's all. Tod's down there under the fall. He's drowned, I tell you! What shall we do? What shall we do!" Excitable Dave was fast losing his head.

"Come on!" shouted Jerry, aroused by the helplessness of his companion. "We've got to get to the mill and have them turn the water through the race. Then we've got to get a boat out there—quick!"

But he had not waited for Dave. Across the river just below the dam was a house. If there was a telephone there—Jerry knew there was one at the mill—something might yet be done in time. There was of course no way of reaching the mill itself across that raging torrent. There was a telephone at the house, but it seemed hours after Jerry reached it before he finally got a gruff "Hello" from the mill manager, Mr. Aikens. But, fortunately, Aikens was not slow to grasp the situation. In the midst of his explanations Jerry realized that there was no one at the other end of the wire.
