As they sailed two degrees farther north, the seamen could scarcely keep themselves warm with the thickest clothing they could put on. They found it difficult also, even with double the number of men, to work the ropes and trim the sails. The crew, not without reason, began to murmur, and declared that they should never be able to endure the cold. The Admiral, however, urged them to persevere. They were standing on when they found themselves close to a shore trending to the westward, and, compelled by a contrary wind, they put into a bay, where they brought up; but the anchorage appearing very insecure, they sailed out again. The Admiral would have continued on his course again in search of a passage, but a northerly wind springing up, drove the _Golden Hind_ once more to the southward. Though it was in the height of summer, the cold continued so bitter, that many would have taken to their beds had they not been compelled to attend to the working of the ship. During this time also the sky became so overcast with clouds and thick mists, that it was impossible to take an observation. At length they came to the conclusion that there was no passage at all along the north shore of America, or that it was so blocked up with ice as to be impassable. They ran in and dropped anchor in a roadstead, since called the Bay of San Francisco. The following day the natives came down to the beach, and sent off a man in a canoe, who, as he approached, stood up and made a long speech, using a variety of gesticulations, moving his hands and turning his head about in all directions. His address concluded, he turned back and made for the shore. In a short time he came again, and behaved exactly in the same manner; a third time he appeared, bringing with him as a present a bunch of feathers, much like those of a black crow, all neatly and cleverly put together, forming a sort of crown, such as was also worn by the principal persons in attendance on the chief. He also produced a small basket made of rushes, filled with a herb, which the natives called _tabak_, from which the French take the word _tabac_, and the English tobacco. Having tied this to a pole, he placed it in the boat alongside. Drake would at once have recompensed him with several articles, but the only thing he would receive was a hat, which was floated off to him. As the ship had sprung a leak and required to be put on shore, she was carried nearer, in order that her cargo might be landed, and that she might be repaired. In order to guard against any attack from the natives, the Admiral decided on throwing up a fort, in which, for security, their valuable cargo and stores might be placed, and which would serve as a protection to themselves.
