Again, they would paddle down to the Narrows, carry the canoe over into the western bay, leave it hidden until sundown, and then go down along the shore on that side of the island, repeating their walk along the shore. Some days they left the canoe hidden for the night away down the island, and came back to the village afoot along the road, going after it afoot the next night, and retracing their search of the night before, thus varying the search in a dozen different ways.

But the result was always the same. It seemed this time as though the Eagle, if it had, indeed, ever lingered in the bay, had gone for good. What might have been the result if those who sailed in search of the mysterious craft had known that the description they now had of her was at fault, can never be known. Be that as it might, the exact yacht that Henry Burns and his friends had seen down at the foot of the island no longer existed. In its place there sailed—somewhere, on some waters—a handsome, black yacht, with a tall, slender, glistening topmast, white sails, and gleaming brass, in place of the dingy, dirty fisherman. She was as fine and handsome, and as polished as to deck and fittings, as the Eagle had been of yore, only her colour remained as it had been changed—black.

Was this boat the Eagle? Those who sailed the bay in quest of her had no means of knowing, for if they ever did get sight of her it was but a far, fleeting, shadowy glance. They never came within miles of her, this fleet, beautiful, and disappearing yacht. Across her stern in letters of gold was the name Sprite. It may have been most appropriate, for now and then a distant view of her tempted some bay craft to follow; but it was like a dog pursuing a bird on the wing. She always drifted on and on, out of reach, and disappeared.

Since the night when the man that rowed Jack Harvey across the bay had climbed aboard this yacht and sailed southward, the yacht had never ventured near Grand Island, nor within miles and miles of it. If the man Chambers had any plan which he meant to execute, it did not suit his purpose to attempt it at this time. He had, perhaps, achieved all he desired now, in familiarizing himself with the waters of this coast.

Of all those who joined in the search for the strange yacht, there was none more enthusiastic nor persistent than Jack Harvey. No sooner had his own yacht been brought back from Bellport by the crew, than he stocked up with a week’s provisions and began cruising day and night. To be sure, it was a most uncertain chase, but Harvey was willing to take chances that others would not; and if he should by mistake intercept some respectable craft for a few brief moments, he would rely on his assurance to carry him through and explain matters.

Harvey had, moreover, a critical eye for a good boat, and had noted the Eagle, when it had been in the harbour, with more than passing interest, and was certain now that he should know her again, even with a change of rig. Besides, he had the description furnished by Henry Burns and the other boys of the yacht they had seen, which corresponded in size with the Eagle.

He had never been so aroused about anything before in all his life. The adventure that Henry Burns and the others had had with the two men that had been caught was an experience after his own heart. He would have given his whole summer’s fun to take part in that capture. But all the glory of that had been denied him; now he made a resolve that if any one succeeded in finding the vanished yacht it should be he.

His activity was not destined to go all for naught, either, for on at least one occasion he was satisfied in his own mind that he had met with the yacht,—yes, and nearly come to close quarters with the man that sailed it.

It was miles below Grand Island, for Harvey had for some days made up his mind that the man he sought had left the bay, since he had scoured it east and west and north and south in vain. It was down among some islands that lay out of the much travelled part of the bay, and not far from the Gull Island Thoroughfare. It was, in fact, just at the outer rim of the bay, where several channels through a chain of islands led out to sea. There were three of the crew aboard besides Harvey, only little Tim being left ashore to guard the camp.

They had been cruising all evening among these islands, for it was a part of the coast with which Harvey was very familiar. They were carrying no lights, for the chances of being run down here were small, and, besides, it was a part of Harvey’s plan to be able to approach any chance craft unobserved.
