"Halt! cease from struggling, or I will kill you!" the man cried, clutching him by the shoulder and endeavoring to place his bayonet against Hal's breast.

The point pierced the thin clothing he was wearing, and dug slightly into the flesh beneath.

"Halt, I say!" the sentry hissed. "The weapon points to your heart, and, by St. James, I will thrust it home if you do but move an inch! Surrender, I say!"

"Never!" Hal answered hoarsely. Then, shaking the sentry's hand off, and pushing his weapon aside with a hasty movement, he stepped back a pace, and struck out blindly with all his might. His fist hit the Spaniard full on the chest, and sent him staggering backwards, and his rifle crashing to the ground. But he recovered himself in a moment, and threw himself upon his prisoner with an exclamation of fury.

"Pig! Villain!" he cried. "Yield, or I will toss you into the water, and drown you like a rat."

Clasped in each other's arms, they swayed from side to side upon the rocks which fringe the margin of the sea. Then Hal's foot twisted upon a stone, and both fell to the ground with a crash.

What followed was a blank to Hal. He remembered nothing, and lay upon the seashore silent and apparently lifeless for the space of more than ten minutes. Then a puff of cold air fanned his cheek, and he suddenly found himself lying with his eyes wide open, staring at the stars above.

"Hillo! What's this?" he murmured vacantly. "Stars! A clear sky! Where is the cabin, then? Where is Billing?"

He stretched out a hand, and touched something that was wet. Then his fingers came in contact with a head of hair, and he withdrew them instantly, with an involuntary shudder. At once the struggle with the sentry flashed across his wandering mind, and brought him to his senses with a start.

"By Jove! I wonder whether he's hurt?" he said. "I'll see, and then cut away for safety, for it will never do to remain here."
