Sergeant True stood on the edge of the plain considering what should next be done. All signs of the trail had ceased as soon as the searchers had come out of the grass and brushwood. There could be no trail upon the flat plain, the Sergeant knew. A large party had just returned from searching the wood between the lake and the fort. There was a bare possibility that the fugitives had ventured to cross the plain, and run the gauntlet of the picket line into the fort; a little stronger possibility that they had skirted the wood by the shore and pushed on down toward the outlet where the Pixie navy lay. True therefore questioned the returning searchers: "Have you seen anything?" "Nothing. Lieutenant MacWhirlie has had the entire strip between lake and fort thoroughly guarded ever since the alarm. Nothing could have passed, he says. Nothing has passed that has left any trail. The Lieutenant has sent scouts down the shore to make sure." Rodney and Pipe heard the report with heavy hearts. Hope was fast dying within them. "Must we give it up?" cried the Commodore. "Is there no deliverance?" "There is but one way by which they could have escaped us," said True, pointing toward the lake. "Is it possible that we have been mistaken, and that pirates have done this outrage after all? Commodore, have there been any boats or ships off shore lately?" "Not one," answered Rodney. "Both fleets are lying by for repairs, for the last fight used them up pretty well. We've been doing shore service ever since." "It is most strange! But we must search the shore thoroughly in this neighborhood, at any rate." The bank of the lake was presently covered with Brownies eagerly scanning by the light of their torches and lanterns every foot of ground. "We have it, we have it!" shouted Rodney. "Come here, Pipe! and you, Waterborn. Look at this!" Immediately a crowd surrounded the excited Commodore. "Stand back!" he cried; "don't push down so close upon the shore until some of the sailors have seen these marks. A boat has landed here within the last half hour. See the wash of the waves upon the sand! And just there the bow has scraped. What say you, lads?" "There is no doubt of it," responded Pipe, after a careful examination. Waterborn, the mate, held his lantern to the water line and after a moment's inspection gave the same opinion. "Here," exclaimed Blythe, "is the crowning proof!" He plucked from the shore a handful of silken threads that had caught upon the sand and gravel which covered the spot where Faith and Sophia must have lain. Yes, they had found the trail again; but only to lose it in the waters of Lake Katrine. "What shall be done?" asked Rodney. "We must follow you now," answered True. "The path lies upon an element of which I know little. You and the Boatswain are at home there. To you who are most wronged Providence gives the opportunity to undo the injury. We yield to the navy, now. Lead on; we'll follow you, you may be sure."
