Struck from behind with the force of a battering-ram, Percy shot over the brink. As he fell he described a partial somersault, landing on hands and knees half-way down the slope. His momentum carried him heels over head, and he rolled and tumbled the rest of the way, bringing up in a heap at the bottom.

He scrambled to his feet, wild with rage. Peals of mirth from the cove reached his ears. His mates and Captain Higgins, as soon as they saw that he was not seriously hurt, had doubled up with laughter. Their outburst of merriment increased Percy's fury.

A triumphant bleat resounded above. Outlined clearly against a background of blue sky, legs well apart and hoofs braced stoutly, Aries stood on the brink, gazing proudly down upon his overthrown enemy. White with wrath, Percy groped for a stone and launched it viciously. It just grazed the ram's head. The laughter from the cove redoubled.

A new idea struck Percy. Darting into the cabin, he ran out with Uncle Tom's shot-gun.

"None of that, Whittington!" bellowed Spurling.

Heedless of the shouted command, Percy clapped the gun to his shoulder and pulled first one trigger and then the other. Click! Click! Both barrels were empty. He might have remembered that so careful a fellow as Jim would never leave a loaded gun standing about. But there were a half-dozen shells in a box on the shelf. Laying the gun down, he rushed back into the cabin.

Spurling realized what Percy was after. Springing into the dory, he sculled rapidly to the beach. He had almost reached the shore when Whittington dashed out of the door with the shells in his hands. He crammed two into the breech, while the ram gazed haughtily down upon him.

"Put that gun down!" shouted Jim as the dory grounded and he leaped out on the beach.

Up went the weapon to Percy's shoulder. His finger sought the trigger, but no report followed. The ram had vanished and the sky-line was unbroken.
