He was moving in a world of enchantment; the weather was like no weather in any known part of the world; there were fogs, black and thick, which blew down suddenly from the low marshy land, and blew away again as suddenly; the sea was sometimes white as milk, sometimes black as pitch, sometimes purple, sometimes green; scarlet cranes stood looking at them as they slid past the low sandbanks; the warm foggy air smelt of roses; shoals of turtles covered the waters, black butterflies circled in the mist; and the fever that was beginning to work in the Admiral's blood mounted to his brain, so that in this land of bad dreams his fixed ideas began to dominate all his other faculties, and he decided that he must certainly be on the coast of Cathay, in the magic land described by Marco Polo. There is nothing which illustrates the arbitrary and despotic government of sea life so well as the nautical phrase "make it so." The very hours of the day, slipping westward under the keel of an east-going ship, are "made" by rigid decree; the captain takes his observation of sun or stars, and announces the position of the ship to be at a certain spot on the surface of the globe; any errors of judgment or deficiencies of method are covered by the words "make it so." And in all the elusive phenomena surrounding him the fevered brain of the Admiral discerned evidence that he was really upon the coast of Asia, although there was no method by which he could place the matter beyond a doubt. The word Asia was not printed upon the sands of Cuba, as it might be upon a map; the lines of longitude did not lie visibly across the surface of the sea; there was nothing but sea and land, the Admiral's charts, and his own conviction. Therefore Columbus decided to "make it so." If there was no other way of being sure that this was the coast of Cathay, he would decree it to be the coast of Cathay by a legal document and by oaths and affidavits. He would force upon the members of his expedition a conviction at least equal to his own; and instead of pursuing any further the coast that stretched interminably west and south-west, he decided to say, in effect, and once and for all, "Let this be the mainland of Asia." He called his secretary to him and made him draw up a form of oath or testament, to which every member of the expedition was required to subscribe, affirming that the land off which they were then lying (12th June 1494), was the mainland of the Indies and that it was possible to return to Spain by land from that place; and every officer who should ever deny it in the future was laid under a penalty of ten thousand maravedis, and every ship's boy or seaman under a penalty of one hundred lashes; and in addition, any member of the expedition denying it in the future was to have his tongue cut out.
