"Put out that pipe," it ordered furiously, and was answered by a low, mocking laugh. There followed the sound of a smashing blow, and a short, sharp struggle that was interrupted by a muffled shout from high overhead. "Hobson ahoy!"

It was Captain Dove who had called cautiously down from the summit of the ridge at one side of the ravine, and the second mate panted a quick response.

"You can get a move on now," cried the old man above the roar of the surf. "The others will all be in position by the time you've pushed through. Open fire as soon as ever you sight the camp. D'ye hear?"

"Ay, ay, sir," answered the second mate, the habit of years still strong upon him, and went on to issue his own commands in the curt growl of custom. The fellow who had lighted a pipe in defiance of him was apparently quelled.

It seemed that he meant to leave some of his men to guard that end of the gorge. "And you'll keep a sharp look-out," he instructed them very threateningly. "If we're trapped in this damned tunnel there will be all hell to pay—and you'll pay it!

"Move on now, in front. Feel your way with your bayonets. And don't fire so long as cold steel will serve."

The two listeners could hear the dull clink and shuffle of the advance. That soon died away. The men who had been left behind began a low, intermittent grumbling over their own hard lot; they did not believe for a moment that their comrades would share the loot fairly with them. Hobson was a coward at heart, said one, or why, otherwise, would they be wasting their time there? They were all smoking by then.

"The whole thing's a cinch," declared the same speaker more loudly. "I'll swear there isn't an Arab outside the ring-fence we've drawn round 'em, and—I'm going on along inside, to get what I want for myself. I'm not afraid of Mr. Blasted Hobson!"

He came out into the open and stood for a moment or two listening intently, within a few feet of where Sallie and Reuben Yoxall were crouching, their backs toward him. But the ceaseless crash and rumble of the breakers was all there was to be heard.

He turned back, and tramped off into the gorge, with two of the others for company. But three remained.
