On Monday, September 17th, four days after Columbus had noted it, the other pilots noted the declination of the needle, which they had found on taking the position of the North star. They did not like it; and Columbus, whose knowledge of astronomy came to his aid, ordered them to take the position of the North star at dawn again, which they did, and found that the needles were true. He evidently thought it useless to communicate to them his scientific speculations, so he explained to them that it was the North star which was moving in its circle, and not the compass. One is compelled to admit that in these little matters of deceit the Admiral always shone. To-day, among the seaweed on the ship's side, he picked up a little crayfish, which he kept for several days, presumably in a bottle in his cabin; and perhaps afterwards ate. So for several days this calm and serene progress westward was maintained. The trade-wind blew steady and true, balmy and warm also; the sky was cloudless, except at morning and evening dusk; and there were for scenery those dazzling expanses of sea and sky, and those gorgeous hues of dawn and sunset, which are only to be found in the happy latitudes. The things that happened to them, the bits of seaweed and fishes that they saw in the water, the birds that flew around them, were observed with a wondering attention and wistful yearning after their meaning such as is known only to children and to sailors adventuring on uncharted seas. The breezes were milder even than those of the Canaries, and the waters always less salt; and the men, forgetting their fears of the monsters of the Sea of Darkness, would bathe alongside in the limpid blue. The little crayfish was a "sure indication of land"; a tunny fish, killed by the company on the Nina, was taken to be an indication from the west, "where I hope in that exalted God, in whose hands are all victories, that land will very soon appear"; they saw another ringtail, "which is not accustomed to sleep on the sea"; two pelicans came to the ship, "which was an indication that land was near"; a large dark cloud appeared to the north, "which is a sign that land is near"; they saw one day a great deal of grass, "although the previous day they had not seen any"; they took a bird with their hands which was like a jay; "it was a river bird and not a sea bird"; they saw a whale, "which is an indication that they are near land, because they always remain near it"; afterwards a pelican came from the west-north-west and went to the south-east, "which was an indication that it left land to the west-north-west, because these birds sleep on land and in the morning they come to the sea in search of food, and do not go twenty leagues from land." And "at dawn two or three small land birds came singing to the ships; and afterwards disappeared before sunrise."
