There were just as strong objections to this supposition, the chief of which was that the vagrants when they went overboard swam with frantic energy toward the shore; in other words, they made for the point where the terror was awaiting them. Moreover, their actions in diving repeatedly and glancing back proved that what they dreaded was behind them.

It was useless to theorize, for the more Mike tried it, the more puzzled he became. He decided to paddle slowly and silently to the point where the tramps had landed and make his investigations there. Using his eyes and ears to the utmost, he ought to learn something, provided always there was something to learn. He certainly displayed “nerve,” but no more than he had done on other occasions.

It has been shown that the youth was only an amateur in handing a canoe, but by slowly and carefully moving the paddle, he caused scarcely a ripple and was sure no one could detect him through the sense of hearing. There was no moon, but the sky was clear and studded with stars whose brilliancy enabled him dimly to see objects at a distance of a hundred yards or so. From the first, he kept so close inshore that the undergrowth and wood were in sight and served him as a guide. Even an expert in the circumstances would not have been able to decide precisely where Biggs and Hutt left the water, but Mike was sure he was not far from the spot when he ceased plying his paddle.

He decided not to land, at least not for the present, but to halt where the bow of the canoe rested directly under the dipping branches. Thus, should it become necessary, he could slip out of sight under the leafy screen, or could retreat if it should prove advisable to do so.

An overhanging bough rested on the prow of the craft and held it motionless, a very slight force serving as an anchor in the case of so delicately poised a craft. First, with his heart beating a little faster than usual, he peered round in the gloom that shut him in on every hand. To the southward he saw the lights of the bungalow twinkling like stars, one of the windows throwing the rays well out on the lake, but in no other direction could be noted a sign of life.

“Every one of the byes, not forgitting Scout Master Hall, are there, for the ones that wint out in t’other canoe must have gone back while I was at the docther’s. They know where I wint so they won’t be worrying about me, which they wouldn’t be likely to do annyhow,” he added with a touch of his natural whimsicality, “if they didn’t know anything about me at all, at all.”

No sound reached the intently listening ears, except that deep almost inaudible murmur which is never absent in a stretch of forest or near the ocean.

“I’ll try it awhile, but if Mike Murphy knows his own heart, which he thinks he do, he isn’t going to sit in this steamboat many more—whisht!”

From a point not fifty feet distant shot out a canoe, like an arrow driven from a bow. In it a single man was seated and vigorously swinging the paddle. He had emerged from under the overhanging limbs and sped southward, absolutely without any noise at all. Mike was so startled by the apparition that he stared breathless for a minute, nor did his wits fully come back until the craft and its occupant were swallowed up in the gloom.

Not only was the unexpected appearance of the canoe startling, but the recognition of the Master of Woodcraft who drove the boat forward like a skimming swallow, added to the amazement of Mike. Beyond a doubt he was Uncle Elk. He was so near when he first darted in view that there was no possibility of mistake.
