With a quick turn and a leap Hal Overton was up and at the throat of his captor. Taken so utterly by surprise the Mexican strove to leap back. But Hal had grappled with him and wrenched the revolver away. The Mexican reached for his handy knife. It was no time for niceties. Hal dealt the fellow a swift blow on top of his head with the butt of the revolver.

Mr. Mexican crumpled and lay where he had stood. But the other Mexican was closing in now.

"Get your hands up as high as you can, fellow!" ordered Hal. Just in the nick of time he remembered Captain Foster's instructions, and spoke in English instead of Spanish. But his gesture was eloquent enough for no words to be needed.

The second Mexican showed no cowardice, yet in this threatened battle at close quarters he dropped his revolver for the more trusted knife.

"Put your hands up and stop this nonsense!" commanded the young officer, stepping forward, holding the revolver at his belt, the muzzle covering the body of the swarthy foe.

The Mexican proved to possess no mean courage. With his knife-hand uplifted he sprang at Hal.

At that very instant a form hurled itself through the air. Private Simms fell at the feet of the Mexican. Without pause the soldier wrapped his arms about the Mexican's knees, throwing the fellow backward with jarring force. In another second Simms had possessed himself of the knife.

"Good!" came a devout chorus from the five bound but watching soldiers. "Great!"

"That was a fine specimen of soldierly wit and promptness, Simms," commended Lieutenant Hal heartily.

"Not half equal to what I've heard that you've done in the Philippines and elsewhere, sir," replied Simms modestly, as he seated himself on the fallen foe. "Will you take this knife, sir, and free the other men, or shall I leave this fellow in your care while I set the men free?"
