“Certainly not, but what is the idea, Mike?”

“’Cause I can’t think of anything ilse to do, as the p’liceman said whin he prosaaded to break his club over the head of ivery one in sight.”

“Were there ever two such pests? The next time I get a chance I won’t kill them, but I’ll give each something he’ll remember.”

“Where’s your boat?”

“At the foot of the path leading to the house; the distance is so short that I did not use it, but strolled to this point.”

“Let’s jump into the same and make fur these spalpeens.”

The physician was so angry that he did not hesitate. They hurried through the wood to the spot where the other craft lay as it had been left by its owner. It has been shown that from this spot the house was not visible and therefore the wife and daughter knew nothing of what was afoot, which perhaps was best. The doctor, being the most skilful with the paddle, took up the implement, and headed after the other craft, which was making good progress toward the farther end of the lake.

Each of our friends had asked himself the question as to what Biggs and Hutt meant by their act and what they were likely to do. It could not be seen that the vagrants had anything to gain, for they must soon abandon the canoe and continue their flight on foot. They knew the medical man carried a deadly weapon, and did not seem backward in using it, because of which they certainly could not desire another meeting with him.

Moreover, a third canoe was involved. It seemed to have disappeared for the time, but must be somewhere near the western end of the lake, which being the case, the tramps were likely to find themselves between two fires, though it was not to be supposed that they had any cause to fear the unarmed Boy Scouts in the invisible boat.

The flight and pursuit had lasted only a few minutes when an unpleasant truth impressed itself upon Mike and the doctor:—Buzby Biggs, who swung the other paddle, did it so deftly that his boat steadily drew away from the pursuer despite the utmost efforts of Dr. Spellman. In a straightaway race the tramps were sure to win, but the course had bounds, and in the end they must be pocketed, a fact so apparent that they themselves saw it from the first. They had the choice of keeping directly on until they reached the western margin so far in advance of their pursuers that they need give them no thought, or they could take the shorter course to the northern shore, opposite the bungalow. It looked as if they had decided upon the former plan, which would indicate that they knew or suspected nothing of the third canoe, nestling somewhere under the overhanging limbs along shore.
