this the spot where you stepped ashore?”
Mike moved farther until his shoes touched the water. He recognized the projecting limb of a beech which had attracted his notice when he came ashore.
“There’s no mistake about the same. Now, docther, that boat can’t hev a habit of sneakin’ off whin ye’re not watching – what’s the matter?”
His companion touched his arm and pointed over the water.
“There’s the answer to your question.”
“It beats me, as the drum said to the drum stick.”
Some two hundred yards out on Gosling Lake was the canoe heading toward the western end of the sheet of water. In it were seated Biggs and Hutt, the two rascally tramps, their appearance suggesting that they were owners of the graceful craft in which they were making a pleasure excursion. Their backs were toward the two on shore, but Hutt who sat near the stern turned his head. Observing the indignant couple, he waved his hand in salutation and grinned so broadly that the gleam of his yellow teeth showed.
Neither Mike nor the doctor spoke for a moment or two. Then the youth solemnly extended his hand.
“Docther, would ye mind shaking?”
“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.
Such undoubtedly would have been the action of the tramps, had not it changed so abruptly and inexplicably that the astounded doctor ceased paddling and stared without speaking a word.
Since our friends sat with their faces toward the backs of Biggs and Hutt, they saw their every movement no matter how slight. Hutt was idle, with a grimy hand resting on either gunwale of the canoe. Now and then he glanced back and when he saw the pursuers steadily falling behind, had the impudence to reach out one hand and beckon them to move faster. The other, knowing he could not be overtaken, showed little interest in those who were striving to come up with him. Something far in advance seemed to hold his attention.
Such was the situation, and the forward boat was within a furlong of the western shore when Biggs suddenly held his paddle suspended as if he had caught sight of some object that startled him. The next moment he flung aside the implement, uttered a cry of terror and dived overboard. Hutt was not five seconds behind him. Both stayed so long under water that our friends suspected they were drowned, but the frowsy heads, one without a hat, bobbed up at some distance from the boat, and they were seen swimming furiously toward the northern bank, which was not far off.
They had not taken a dozen strokes when they dived again and went as far under the surface as before. Thus diving, swimming and working desperately, they quickly reached land, scrambled out, plunged in among the trees and vanished as if Death himself were nipping at their heels. Never was greater panic shown.
Doctor Spellman sat mute and motionless until the tramps had disappeared. Then he turned his head:
“What do you make of that, Mike?”
The occasion was one of the rare ones when the Irish youth had nothing to say. He sighed and shook his head; he couldn’t do justice to the theme.
“Something scared both of them out of their wits. It couldn’t have been on the shore ahead, for that’s too far off, nor on their right, for they tried with might and main to reach land there.”
“Could it have been at the rear?” ventured Mike.
“That is toward us. We couldn’t have caused them such alarm.”
“Mr. Hutt may have looked around and catched the frown on me brow; I’m towld I have a tumble exprission when I’m mad.”
“It must be true to cause them thus to leap into clear spring water, knowing it meant the coldest kind of a bath. No, Mike,” added the doctor gravely, “they saw something in the water that threw them into fits. What could it be?”
This was the only theory possible and yet it simply deepened the mystery. What could there be in the clear cool waters of Gosling Lake, besides the different species of ordinary fishes that are taken with hook and line? To Mike and the doctor the puzzle was more inexplainable than before.
One conclusion, however, was warranted by what had occurred: if the tramps had seen something which terrified them beyond imagination, what was to prevent the man and youth from gaining a sight of the same frightful object whatever it might be?
Now, while it cannot be denied that Dr. Spellman and Mike Murphy were more than ordinarily brave, yet they felt a shrinking in stealing up to the spot where the tramps had dived from the other canoe. It was their ignorance of the character of the peril which affected them more than any tangible danger could have done.
The doctor dipped his paddle in the water and gently swayed it. The boat moved slowly toward the other canoe, drifting like an eggshell over the placid surface. In leaping overboard, Buzby Biggs had flung the paddle from him and it was seen floating a couple of rods distant from the boat. Very slowly the doctor advanced until Mike leaned over and lifted the implement into their craft. Then the man sheered his boat beside the other and Mike, tossing the paddle into it, held it steady, and sat down.
“Now, docther, we can manage it, I’m thinking,” remarked the youth, looking up into the face that it seemed to him had gone a little pale.
“Can you find anything to explain the fright of the tramps, Mike?”
Both peered into the clear water, whose depth was too great for them to see the bottom, but nothing rewarded their piercing scrutiny. And right here a fact must be admitted which was not discreditable to either of them. The breath of air that sighed
