Of this voyage Hakluyt prints the Traverse Book, one of the earliest known. In it the full detail is given for every day, arranged in nine columns, one each for the month, the day, the hour, the courses, the leagues, the elevation of the pole in degrees and minutes, the wind, and a remarks column headed "The Discourse"—for Davis was an exact and systematic man remarkable for his latitudes never being wrong, though like all those old navigators before the invention of the chronometer, he was frequently out in his longitude. He was going off again bound for the sea north of Sanderson's Hope, but the coming of the Armada and the death of Walsingham caused the postponement of the project he did not abandon, for it seems that the _Desire_, in which he discovered the Falkland Islands at the other end of America, was to be his reward for accompanying Cavendish round the world, and that in her he intended to make his next Polar voyage. The work he had set himself to do was done by William Baffin, who first appears in the Arctic record as pilot of the _Patience_ in James Hall's Greenland voyage in 1612, which ended in Hall being killed in revenge for the kidnapping proceedings on the two previous voyages under the Danish flag. Baffin then made two voyages, as we have seen, to Spitsbergen in the service of the Muscovy Company, and, in that of the Company for the Discovery of the North-West Passage, he made his fourth, in 1615. In Hudson's old ship the _Discovery_, also her fourth trip to the north, he passed up Hudson Strait to the end of Southampton Island, where he abandoned the attempt to get through owing to ice and shallow water, and returned after discovering the land that Parry named after him.
