The harbour out of which they were now beating made inland for a mile or two. The waters ran back thence in a salt river for several miles more, before they grew brackish, and then were merged into a stream of fresh water that had its origin in a pond back in the country. It followed, that the waters of the harbour flowed in and out with much swiftness and strength; and now, the flood-tide and the south wind being coincident, coming in together strongly, it was slow working out, even with as good a boat as the Viking. There was a heavy sea running, too, which served to beat them back. They tacked to and fro, but they drew ahead of the landmarks ashore very slowly.

“I say, my lad,” cried Mr. Carleton all at once, stepping aft to where Harvey held the wheel, “let me take her a few minutes and see what I can do, will you? Oh, you needn’t be afraid that I’ll upset you,” he added, as Harvey somewhat reluctantly complied. “I’ve owned boats and sailed them, too,—as good as this one, if I do say it.”

It was clearly evident, as he seated himself astride the helmsman’s seat, that he was no novice. He held the yacht with a practised hand, and, moreover, asserted himself with the rights of skipper.

“Haul in on that main-sheet a little more,” he said to Harvey.

“She won’t do as well with the boom so close aft in a heavy sea,” replied Harvey.

“Oh, yes, she will,” answered Mr. Carleton, coolly. “You are right as a general proposition, but I’ll show you something. I’ve been watching the run of the tide.”

Harvey, not agreeing, still acquiesced in the order, and hauled the boom aft.

“A little more,” insisted Mr. Carleton. “There, that will do. Now you will see us fetch out of the harbour.”

To Harvey’s surprise, and that of the other boys, the yacht certainly was doing better. Mr. Carleton held her so close into the wind that the sail almost shook. Every now and then it quivered slightly. But they surely were making better progress.

“Well,” admitted Harvey at length, “that goes against what I’ve been taught about sailing. The sheet a little off in a heavy sea and keep her under good headway is Captain Sam’s rule.”
