On the afternoon of the 22nd another sail was spy'd and chased to the westward, until "a stiff gale coming on, put us," says Rogers, "out of hopes of seeing her again to advantage." The next day, the weather being fine, with fresh gales, the officers of both ships again dine together on board the "Duke," when a committee is held, and a vote of censure passed upon Mr. Carlton Vanbrugh for landing against the wish of his Captain. No doubt also the quality of the Canary was discussed, and perhaps helped to smooth the course of this debate. [Sidenote: _Pass the Tropick._] It would seem, from the next entry in the log, that the penalties usually exacted by Neptune of those crossing the _Line_ for the first time, then became his due somewhat earlier in the voyage; or upon first entering what sailors call the "Horse latitudes." For Rogers says that September the 25th "we passed the tropick, and according to custom duck'd those that had not done so before. The manner of doing it was by a rope thro' a block from the main yard to hoist 'em above halfway up to the yard and let 'em fall at once into the water, having a stick cross thro their legs, and well fastened to the rope, that they might not be surprised and let go their hold. [Illustration: _Crossing the Tropick._] "This prov'd of great use to our freshwater sailors to recover the colour of their skins, which were grown very black and nasty. Those that we duck'd after this manner three times, were about sixty, and others that would not undergo it chose to pay half a crown fine; the money to be levy'd and spent at a public meeting of all the ships companies when we return to England. The Dutchmen and some Englishmen desir'd to be duck'd, some six, others eight, ten, and twelve times, to have the better title for being treated when they come home." The "Duke" and "Dutchess" made the Island of Sal, one of the Cape de Verds, on the morning of September 29th, and "after being satisfied," says Rogers, "it was Sal, we stood from it W. and W. by N. for St. Vincent, going under easy sail all night because we had none aboard either ship that was acquainted with these islands; but on the 30th when day broke we saw 'em all in a range much as is laid down in the draughts, and at ten o'clock anchored in the bay of St. Vincent in five fathom water." When one considers the means by which these early master mariners determined their position at sea, and that for want of good timekeepers they were almost quite dependent upon dead reckoning for their longitude, the accuracy and boldness with which Rogers made his landfalls is truly surprising. The accompanying figures, from a standard work upon navigation of the period,[6] are interesting as showing the curious form of nautical instruments used by old shipmen, like Woodes Rogers, for taking altitudes of the sun, moon, pole, stars, &c., before the invention of Hadley's quadrant.
