Together the two raised as loud a shout as they could.

In a moment the drumming stopped.

Again the two lads in the water shouted: "Here! here! here!"

The drumming began and the light at the bow, which showed plainly now, although the boat itself was still hidden, swung and lurched as the motor boat swept around in a curve. With rescue in sight the boys threw their last energy into a fusillade of shouts and soon, "Ha-yo, where are you?" came a hail from the boat.

"Look out, look out, you'll run us down," yelled the boys.

A bell rang; the motor stopped and cut silently through the waves only a few yards away.

"Here, here!" shouted Frank.

"Great Cæsar!" said a voice from the boat, "it is some one in the water. Stop her quick," as the boat was driving past the boys with her momentum. "Back her! Back her!" yelled the voice now in great excitement. "We've found them. They're in the water."

In a less time than it takes to tell it the captain had maneuvered the boat to within reaching distance of the two in the water. Strong hands reached over the sides and quickly pulled them to safety. Neither could stand. They sank down into the bottom of the boat. Frank looked up and saw his father standing over him.

"Back to Flat Rock, quick," gasped Frank. "Quick, there are two boys out there!"
