"Why not?"

"It may be wise at this stage of the game not to let them know that you can surpa.s.s them. Wait till the necessity arises."

"I agree with Mr. Calvert," added Chester, and the Captain was impressed by the logic of the counsel. He was on the point of increasing the pace, but refrained. In truth he was already wondering what they would do if they overtook the other and what could be gained by pa.s.sing the boat.

Again the whistle piped several times and it was evident that the fugitive, as it may be called, had "put on more steam."

"Do you wish me to let her get away from us?" asked Alvin.

"Not for the present, but that may be the best course. Hold your own for awhile and then gradually fall back."

When the race opened, less than an eighth of a mile separated the contestants. The abrupt burst lessened this slightly and then it appeared to be stationary as the two glided down the river.

Such were the relative positions when the _Water Witch_ shot past Ram Island, holding the middle of the stream, and a few minutes later came abreast of Isle of Springs.

"Those two young fellows have a man with them," remarked Calvert. "He tried to keep out of sight when we first met, but now he doesn't seem to care. You can see him plainly without the help of the gla.s.ses."

Such was the fact, and Chester said:

"They must know that we also have a friend with us."

"I don't see that it matters either way. I think you are gaining."

"But not half fast enough," added Mike, who was standing and impatient to beat their opponent. "We must come up wid the spalpeens before they git to Boothbay."

"They are not heading for Boothbay," observed Calvert, whose keen eyes had detected the change in the line of flight. His companions saw he was right. The front boat had made so abrupt a change of course that it was almost at right angles to that of the pursuer. The side of the launch was exposed, showing the two youths, one of whom held the wheel, while the man with a mustache sat directly beside the other. It might be said of the two craft and their crews that they were twins, so marked was their resemblance.

Naturally Alvin shifted his line of pursuit. You may recall that, opposite the Isle of Springs, Goose Rock Pa.s.sage connects Sheepscot River with Knubble Bay, which leads into Montsweag Bay, reaching northward on the western side of the long island of Westport. In their first trip northward our young friends had gone to the eastward of Westport, as they had been doing during this race. Montsweag Bay takes the name of Back River at the northern end of the island and that and the Sheepscot unite above before reaching Wisca.s.set.

The _Water Witch_ dived into Goose Neck Pa.s.sage past Newd.i.c.k Point, where it turned northward into Knubble Bay. This is the path taken by the steamers from Bath and other places on the Kennebec when going to Boothbay Harbor, Squirrel Island and other points. To the westward of these bodies of water sweeps the n.o.ble Kennebec to the sea.

Just ahead was discerned a swiftly approaching ma.s.s of tumbling water, above which the deck, pilot house and puffing smokestack of a little steamer showed. This was the "pony of the Kennebec"--the _Gardiner_, plowing ahead in such desperate haste that one might well believe the fate of a score of persons depended upon its not losing a half minute.

Alvin took good care to give her plenty of room and saluted with several whistle toots. There was no reply. The captain merely glanced at the two craft and sped onward like an arrow from the bow of the hunter.

The _Deerfoot_ rocked and plunged in the swell made by the steamer, which, spreading out like a fan from its bow, ran tumbling and foaming along the rocky sh.o.r.es, keeping pace with the headlong charge of the boat, and trying to engulf everything in its path. One small catboat that was tied to a rickety, home-made landing, after a couple of dives capsized, as if it were a giant flapjack under which a housewife had slid her turning iron.

"They're gaining!" exclaimed Chester, who was closely watching the progress of the racers. "Do you mean to let them get away, Alvin?"

"Mr. Calvert will answer that question."

"I do so by advising that you neither gain nor lose for the present."

The Captain gave the launch a little more power, and it became clear to all that the pursuer was picking up the ground, or rather water, that she had lost. Then for several minutes no difference in speed was perceptible. A s.p.a.ce of a furlong separated the two when they shot past the point of land bearing the odd name of Thomas Great Toe, which is on the western side of the lower part of Westport, some two miles above Goose Neck Pa.s.sage. Here the water is a mile in width, and is filled with islands of varying sizes, until the large bay to the northward is reached.

The _Water Witch_ persisted in hugging the eastern sh.o.r.e, while her pursuer kept well out, as if to make sure of having plenty of room in which to pa.s.s her, when the chance came. But all the same the chance did not come. It was soon seen that the fugitive was drawing away from her pursuer. Mike Murphy fumed, but held his peace.

"It's mesilf that hasn't any inflooence here," he reflected, "as I obsarved to mysilf whin dad and mither agreed that a thundering big licking was due me."

"Can you overhaul her?" asked Detective Calvert.

"Easiest thing in the world; I can shoot past her as if she were lying still."

"Well, don't do it."

Mike could remain silent no longer.

"That's a dooce of a way to run a race! Whin ye find ye can bate the ither out of sight ye fall back and let her doot. That's the style I used to run races wid the ither boys at school, but the raison was I couldn't help it. If ye'll allow me to utter a few words of wisdom I'll do the same."

Alvin nodded his head.

"It is that ye signal to that pirut ahead to wait and give us a tow, being that's the only way we can howld our own wid 'em."

Now while it was trying to Alvin and Chester to engage in a race of the nature described and voluntarily allow the contestant to beat them, when they knew they had the power of winning, yet they believed it was the true policy, since Detective Calvert had said so. They understood the disgust of Mike and could not forbear having a little fun at his expense.

"You see," said Chester gravely, "those two young men who gave you and Alvin such a warm time the other night are on the other boat, and if we should come to close quarters with them they would be pretty sure to even up matters with you."

Mike glared at the speaker, as if doubting the evidence of his ears.

"Phwat is that ye're saying?" he demanded. "Isn't that the dearest object of yer heart? I shall niver die contint till I squar' matters wid 'em, and ye knows the same."

"You forget," added Calvert, with the same seriousness, "that they have a full-grown man to help them out."

"And haven't we a full-grown man wid us, as me dad said whin he inthrodooced me to his friends at Donnybrook, I being 'liven years old?

Begorra, I'm thinking we haven't any such person on boord."

It was a pretty sharp retort, but the officer could not repress his amus.e.m.e.nt at the angry words. Alvin looked over his shoulder and winked at Calvert and Chester, making sure that Mike did not observe the signal.

In his impatience, he had turned his back upon them and was looking gloomily over the stern at the foaming wake.

"I wonder if there isn't some tub along the sh.o.r.e that'll put out and run us down. I hope, Captain, that whin we git back home ye'll kaap this a secret from dad."

"And why?"

"He'll sure give me the greatest walloping of me life."

"For what reason?"

"For consoorting wid a party that run away from the finest chance in the wurrld for a shindy. It's a sin that can be wiped out in no ither way."

"I'll explain to him," said Calvert, "that you couldn't help yourself."

"And it's mighty little difference that will make, as Terry McCarthy said when he had the ch'ice of foighting two Tipperary byes or three Corkonians."

"Wouldn't your father prefer to have us bring you home safe and unhurt rather than to have your beauty battered out of you?" inquired the detective, with a solemn visage.

Mike, who had risen to his feet and was still staring over the stern, slowly turned and faced the questioner. Then, with an expression of contempt, he said:

"Ye haven't the honor of an acquaintance wid me dad."
