There was a southwesterly blowing, with some prospect of its holding on late. So, after clearing up accounts with Mr. Hollis, the trader, and having an early supper in the harbour, where they were free from the pitching of the sea outside, they got under way and stood up once more for Grand Island, running free before a good breeze. It was about five o’clock in the afternoon, and, if the wind held, they would make the foot of Grand Island by nine o’clock. They were impatient to be back at Southport, and were willing to sail at night if need be.

And yet it was a mere chance that should bring them in to the Thoroughfare on time; for, just north of North Haven, and before they had come to the group of islands beyond, some one suggested that they stand on for Southport and go down to the Thoroughfare the next morning. Harvey half-assented, and then, with a fondness that still lingered for his old boat, was doubtful.

“What do you say, Henry?” he had asked of Henry Burns. “I’ll do as you think about it.”

“Oh, better go down to-night and relieve the crew,” said Henry Burns. “They’re probably sick of staying there by this time, all alone. At any rate, we’ll leave them a new supply of food.”

But Henry Burns himself would rather have gone to Southport.

The wind held on for all of the eighteen miles they had to run; but it dropped away to a very light breeze just at sundown, then freshened a little soon after. It was not until near eleven o’clock, however, instead of nine, as they had expected, that they entered and sailed up the Thoroughfare.

Tom Harris, as lookout forward to watch the shoaling of the channel, saw, all at once, something that made his flesh creep. A stout, wholesome lad was Tom Harris, too, with no superstition about him. Yet he had heard sailors’ yarns of ghostly things in the sea—and he might almost have been warranted in thinking he now beheld something of that sort.

There, off the port bow, about an eighth of a mile from shore, was something that did look strangely like a human head bobbing along; and if there wasn’t an arm lifted again and again from the water, as of some one swimming a side-stroke, why, then Tom Harris was dreaming, or seeing some seaman’s phantom. He had to believe his own eyes, though; and yet how could it be, away down at this end of the island, where there were no cabins of any sort—and the crew up beyond?

“Jack, Henry, Bob,” he whispered, excitedly, “there’s a queer thing swimming just ahead there. It may be a big fish or a seal, but it looks different to me.”

“That’s no fish,” cried Harvey, springing to his feet. “It’s some one swimming. I’ll bet it’s one of the crew. Little Tim Reardon, most likely. Just like the little chap to try to surprise us. He’s the best swimmer I ever saw. Learned it around the docks up the river before he was seven years old.”
