He had kept his eyes closed a full half hour, because, with sight shut off, the other senses became much more acute for the time. The power that had been in the eyes was poured into their allies. Imagination, in particular, leaped into a sudden luxuriant growth. It was true, of course it was quite true, that those friendly spirits of the air were singing all about him. They were singing in unison a gay and brilliant song, very pleasant to hear, until he was startled by a new note that came into it, a note not in harmony with the others, the voice of Cassandra herself. He listened and he was sure. Beyond a doubt it was a note of warning.
Robert opened his eyes and everything went away. There was the pleasant, green island, and there was the deep blue sea all about it. He laughed to himself. He was letting imagination go too far. One could make believe too much. He sat idly a few minutes and then, putting the glasses to his eyes, took another survey of the far horizon where blue sky and blue water met. He moved the focus slowly around the circle, and when he came to a point in the east he started violently, then sprang to his feet, every pulse leaping.
He had seen a tiny black dot upon the water, one that broke the continuity of the horizon line, and, for a little while, he was too excited to look again. He stood, the glasses in his trembling fingers and stared with naked eyes that he knew could not see. After a while he put the glasses back and then followed the horizon. He was afraid that it was an illusion, that his imagination had become too vivid, creating for him the thing that was not, and now that he was a little calmer he meant to put it to the proof.
He moved the glasses slowly from north to east, following the line where sky and water met, and then the hands that held them trembled again. There was the black spot, a trifle larger now, and, forcing his nerves to be calm, he stared at it a long time, how long he never knew, but long enough for him to see it grow and take form and shape, for the infinitesimal but definite outline of mast, sails and hull to emerge, and then for a complete ship to be disclosed.
The ship was coming toward the island. The increase in size told him that. It was no will-o'-the-wisp on the water, appearing a moment, then gone, foully cheating his hopes. If she kept her course, and there was no reason why she should not, she would make the island. He had no doubt from the first that a landing there was its definite purpose, most likely for water.
When he took the glasses from his eyes the second time he gave way to joy. Rescue was at hand. The ship, wherever she went, would take him to some place where human beings lived, and he could go thence to his own country. He would yet be in time to take part in the great campaign against Quebec, sharing the dangers and glory with Willet, Tayoga, Grosvenor and the others. The spirits in the air had sung to him a true song, when his eyes were shut, and, in his leaping exultation, he forgot the warning note that had appeared in their song, faint, almost buried, but nevertheless there.
He put the glasses to his eyes a third time. The ship was tacking, but that was necessary, and it was just as certain as ever that her destination was the island. Owing to the shifts and flaws in the wind it would be night before she arrived, but that did not matter to him. Having waited months he could wait a few hours longer. Likely as not she was an English ship out of the Barbadoes, bound for the Carolinas. He must be somewhere near just such a course. Or, maybe she was a colonial schooner, one of those bold craft from Boston. There was a certain luxury in speculating on it, and in prolonging a doubt which would certainly be solved by midnight, and to his satisfaction. It was not often that in real life one looked at a play bound to develop within a given time to a dramatic and satisfying finish.
He remained on the crest until late in the afternoon, watching the ship as she tacked with the varying winds, but, in the end, always bearing toward the island. He was quite sure now that her arrival would be after dark. She would come through the opening in the reefs that he and the slaver had made so hardly in the storm, but on the night bound to follow such a day it would be as easy as entering a drawing room, with the doors held open, and the guest made welcome. He would be there to give the welcome.
He was able to see more of the ship now. As he had surmised, she was a schooner, apparently very trim and handled well. Doubtless she was fast. The faster the better, because he was eager to get back to the province of New York.
Late in the afternoon, he left the hill and went swiftly back to his house, where he ate an early supper in order that he might be on the beach to give welcome to the guest, and perhaps lend some helpful advice about making port. There was none better fitted than he. He was the oldest resident of the island. Nobody could be jealous of his position as adviser to the arriving vessel.
