Constrained to cut the painter lest the dory be drawn down with the fast-sinking submarine, he fitted oars to locks and put his back to them, swinging the small boat hastily clear of whirlpools which formed as the waves closed over the spot where the U-boat had rested.

From first to last less than five minutes' activity had been needed for the task of scotching this water-moccasin of the salt seas and putting its keepers at the mercy of the country whose hospitality they had too long abused.

Well content, after a little, Lanyard lay on his oars and contemplated with much interest what the night permitted to be visible: the landing stage, no more than a dark, vague mass in the darkness; the land picked out with but few lights, mainly at windows of the base buildings, painting dim ribbons upon the polished floor of the lagoon.

Methodically these were eclipsed as a moving figure passed before them.

Listening intently, Lanyard could distinguish the slow footfalls of an unsuspecting sentry—no other sounds, more than gentle voices of the night: murmurs of blind wavelets, the plaintive whisper of a little breeze belated amid the tree-tops of that dark forest, and a slow, weary soughing of swells upon the distant ocean shore.

Perceiving as yet not the slightest indication of an alarm ashore, Lanyard ventured to continue rowing, but with utmost caution, lifting and dipping his blades as gingerly as though they were fashioned of brittle glass, and for want of a better guide keeping the stern of the dory square to the shank of the T-stage.

In time the bows grounded lightly on sand. The melancholy voice of the sea now seemed a heavier sighing in the stillness. He pushed off and rowed on parallel with a dark shore line, so close in that his starboard oar touched bottom at each stroke.

At intervals he paused and rested, striving vainly to garner some clue to his bearings. Inexorably the blackness forbade that. He might have failed ere dawn to grope a way out of that trap had not the disappearance of the submarine been discovered within the hour.

A sudden clamour rose in the quarter of the landing stage, first one great shout of dismay, then two voices bellowing together, then others. Several rifle-shots were fired in the air. More lights broke out in windows ashore. Many feet drummed resoundingly upon the stage, and the confusion of voices attained a pitch of wild, hysteric uproar. Of a sudden a flare was lighted and tossed far out upon the bosom of the lagoon.

Surprised by that sharp and merciless blue glare, Lanyard instinctively shipped oars and picked up the rifle. He could see so clearly that huddle of figures upon the head of the landing stage that he confidently apprehended being fired upon at any moment; but minutes lengthened and he was not. Either the Germans were looking for bigger game than a dory adrift, or the dazzling flare hindered more than aided their vision.
