"And yet thou wouldst now brazen it out, and deny thy terror! Didst thou not swear to thy fellows, that thou hadst often seen this deviation before; ay, even on as many as twenty occasions?"
"Well, Excellency, this is a proof that a cavalier may make a very capital viceroy and admiral, and know all about Cathay, without having the clearest notions of history! I told my shipmates, Don Christopher, that I had noted these changes before this night, and if tied to the stake to be burnt as a martyr, as I sometimes think will one day be the fate of all of us superfluously honest men, I would call on yourself, Señor Almirante, as the witness of the truth of what I had sworn to."
"Thou wouldst, then, summon a most unfortunate witness, Sancho, since I neither practise false oaths myself, nor encourage their use in others."
"Don Luis de Bobadilla y Pedro de Muños, here, would then be my reliance," said the imperturbable Sancho; "for proof a man hath a right to, when wrongfully accused, and proof I will have. Your Excellency will please to remember that it was on the night of Saturday, the 15th, that I first notified your worship of this very change, and that we are now at the night of Monday, the 17th. I swore to twenty times noting this phenomenon, as it is called, in those eight-and-forty hours, when it would have been nearer the truth had I said two hundred times. Santa Maria! I did nothing but note it for the first few hours!"
"Go to, Sancho; thy conscience hath its latitude as well as its longitude; but thou hast thy uses. Now, that thou understandest the reason of the variation, however, thou wilt encourage thy fellows, as well as keep up thy spirits."
"I make no question that it is all as your Excellency sayeth about the star's travelling," returned Sancho; "and it hath crossed my mind that it is possible we are nearer Cathay than we have thought; this movement being made by some evil-disposed spirits on purpose to make us lose the way."
"Go to thy hammock, knave, and bethink thee of thy sins; leaving the reasons of these mysteries to those who are better taught. There is thy dobla, and see that thou art discreet."
In the morning every being in the three caravels waited impatiently for the results of the new observations. As the wind continued favorable, though far from fresh, and a current was found setting to the westward, the vessels had made, in the course of twenty-four hours, more than a hundred and fifty miles, which rendered the increase in the variation perceptible, thus corroborating a prophecy of Columbus, that had been ventured on previous observation. So easily are the ignorant the dupes of the plausible, that this solution temporarily satisfied all doubts, and it was generally believed that the star had moved, while the needle remained true.
How far Columbus was misled by his own logic in this affair, is still a matter of doubt. That he resorted to deceptions which might be considered innocent, in order to keep up the courage of his companions, is seen in the fact of the false, or public reckoning; but there is no proof that this was one of the instances in which he had recourse to such means. No person of any science believed, even when the variation of the compass was unknown, that the needle pointed necessarily to the polar star; the coincidence in the direction of the magnetic needle and the position of the heavenly body, being thought accidental; and there is nothing extravagant in supposing that the admiral—who had the instrument in his possession, and was able to ascertain that none of its virtue was visibly lost, while he could only reason from supposed analogy concerning the evolutions of the star—should imagine that a friend he had ever found so faithful, had now deserted him, leaving him disposed to throw the whole mystery of the phenomenon on the more distant dwellers in space. Two opinions have been ventured concerning the belief of the celebrated navigator, in the theory he advanced on this occasion; the one affirming, and the other denying his good faith in urging the doctrine he had laid down. Those who assert the latter, however, would seem to reason a little loosely themselves, their argument mainly resting on the improbability of a man like Columbus uttering so gross a scientific error, at a time when science itself knew no more of the existence of the phenomenon, than is known to-day of its cause. Still it is possible that the admiral may not have had any settled notions on the subject, even while he was half inclined to hope his explanation was correct; for it is certain that, in the midst of the astronomical and geographical ignorance of his age, this extraordinary man had many accurate and sublime glimpses of truths that were still in embryo as respected their development and demonstration by the lights of precise and inductive reasoning.
Fortunately, if the light brought with it the means of ascertaining with certainty the variation of the needle, it also brought the means of perceiving that the sea was still covered with weeds, and other signs that were thought to be encouraging, as connected with the vicinity of land. The current being now in the same direction as the wind, the surface of the ocean was literally as smooth as that of an inland sheet of water, and the vessels were enabled to sail, without danger, within a few fathoms of each other.
