The vessels being all refitted, the admiral weighed anchor from Gran Canaria on Saturday, September 1st, and arrived next day at Gomera, where four days were employed in completing their stores of provisions and of wood and water. On the morning of Thursday, September 6, 1492, the admiral took his departure from Gomera, and commenced his great undertaking by standing directly westward, but made very slow progress at first on account of calms. On Sunday, September 9th, about daybreak, they were nine leagues west of the island of Ferro. Now, losing sight of land and stretching out into utterly unknown seas, many of the people expressed their anxiety and fear that it might be long before they should see land again; but the admiral used every endeavor to comfort them with the assurance of soon finding the land he was in search of, and raised their hopes of acquiring wealth and honor by the discovery. To lessen the fear which they entertained of the length of way they had to sail, he gave out that they had only proceeded fifteen leagues that day, when the actual distance sailed was eighteen; and, to induce the people to believe that they were not so far from Spain as they really were, he resolved to keep considerably short in his reckoning during the whole voyage, though he carefully recorded the true reckoning every day in private. On Wednesday, September 12th, having got to about one hundred fifty leagues west of Ferro, they discovered a large trunk of a tree, sufficient to have been the mast of a vessel of one hundred twenty tons, and which seemed to have been a long time in the water. At this distance from Ferro, and for somewhat farther on, the current was found to set strongly to the northeast. Next day, when they had run fifty leagues farther westward, the needle was observed to vary half a point to the eastward of north, and next morning the variation was a whole point east. This variation of the compass had never been before observed, and therefore the admiral was much surprised at the phenomenon, and concluded that the needle did not actually point toward the polar star, but to some other fixed point. Three days afterward, when almost one hundred leagues farther west, he was still more astonished at the irregularity of the variation; for, having observed the needle to vary a whole point to the eastward at night, it pointed directly northward in the morning.
