The Arato sailed well with a fair wind, but in many respects she was not as good a sea-boat in a storm as the Miranda had proved to be, and she had been obliged to lie to a great deal through the days and nights of high winds and heavy seas. Having never had, until now, the responsibility of a vessel upon him, Cardatas was a good deal more cautious and prudent, perhaps, than Captain Horn would have been had he been in command of the Arato. Among other methods of precaution which Cardatas thought it wise to take, he steered well out from the coast, and thus greatly lengthened his course, and at last, when a clearing sky enabled him to take an observation, he found himself so far to the westward that he changed his course entirely and steered for the southeast.
Notwithstanding all these retarding circumstances, Cardatas did not despair of overhauling the Miranda. He was sure she would make for the Straits, and he did not in the least doubt that, with good winds, he could overtake her before she reached them, and even if she did get out of them, he could still follow her. His belief that the Arato could sail two miles to the Miranda's one was still unshaken. The only real fear he had was that the Miranda might have foundered in the storm. If that should happen to be the case, their voyage would be a losing one, indeed, but he said nothing of his fears to Nunez.
The horse-dealer was now on deck again, in pretty fair condition, but he was beginning to be despondent. After such an awful storm, and in all that chaos of waves, what chance was there of finding a little brig such as they were after?
"But vessels sail in regular courses," Cardatas said to him. "They don't go meandering all over the ocean. If they are bound for any particular place, they go there on the shortest safe line they can lay down on the map. We can go on that line, too, although we may be thrown out of it by storms. But we can strike it again, and then all we have to do is to keep on it as straight as we can, and we are bound to overtake another vessel on the same course, provided we sail faster than she does. It is all plain enough, don't you see?"
Nunez could not help seeing, but he was a little cross, nevertheless. The map and the ocean were wonderfully different.
The wind had changed, and the Arato did not make very good sailing on her southeastern course. High as was her captain's opinion of her, she never had sailed, nor ever could sail, two miles to the Miranda's one, although she was a good deal faster than the brig. But she was fairly well handled, and in due course of time she approached so near the coast that her lookout sighted land, which land Cardatas, consulting his chart, concluded must be one of the Patagonian islands to the north of the Gulf of Penas.
As night came on, Cardatas determined to change his course somewhat to the south, as he did not care to trust himself too near the coast, when suddenly the lookout reported a light on the port bow. Cardatas had sailed down this coast before, but he had never heard of a lighthouse in the region, and with his glass he watched the light. But he could not make it out. It was a strange light, for sometimes it was bright and sometimes dull, then it would increase greatly and almost fade away again.
"It looks like a fire on shore," said he, and some of the other men who took the glass agreed with him.
"And what does that mean?" asked Nunez.
"I don't know," replied Cardatas, curtly. "How should I? But one thing I do know, and that is that I shall lie to until morning, and then we can feel our way near to the coast and see what it does mean."
