“You’re too much for me, Mike. I’m proud to take off my hat to you.”

“And it’s me dooty to be equally respictful, as me dad said whin the bull pitched him over the fence and stood scraping one hoof and bowing from t’other side.”

While still in the boat, Alvin and Chester had returned the salutation of Calvert. The Captain remained seated at the wheel, but the second mate stepped out on the float and a general introduction followed. The detective and he went aboard and sat down on one of the seats. Mike kept them company, and throwing in the clutch, Alvin guided the launch into the spacious waters outside, all three waving a salute to Westerfield, who stood on the float and watched them for some minutes.

Detective Calvert had the good sense fully to admit Mike Murphy to his confidence, though he had hoped at first he would not be a member of the party. Alvin Landon gave the man to understand that he was not hiring out his boat, but was conferring a favor upon the officer, who had the choice of rejecting or accepting it on the terms offered. While Calvert could not doubt the loyalty of the young Hibernian, he distrusted his impulsiveness. But as I have said, having decided upon his line of conduct, he did not allow himself to show the slightest degree of distrust.

Mike on his part was tactful enough to act as listener while the man made clear his plans. He did not ask a question or speak until addressed. The launch moved so quietly that Alvin, with his hands upon the wheel and scanning the water in front, heard all that was said by the others, and when he thought it fitting took part in the conversation.

Instead of returning to Southport, the Deerfoot circled Cape Newagen, which you know is the southern extremity of that island, and entering the broad bay, headed up the Sheepscot River, over the same course it had followed before.

“Mike was not with you,” said Detective Calvert, “when you traced the other launch into that little inlet at the lower end of Barter Island. That boat stayed there overnight and may still be there, but probably is not.”

“Suppose it isn’t there?” said Chester.

“We must find out where she is. That is the chief reason for my presuming upon the kindness of the Captain to lend me the help of his launch. In other words, it is my wish that the Deerfoot shall serve as the Scout of the Kennebec.”

“A romantic title,” remarked Alvin, over his shoulder, “though we are not cruising on the Kennebec, but up the Sheepscot.”
