The voyages of Hall in 1612 and Gibbons in 1614 did not result in much, but in 1615 William Baffin started out on the first of his two expeditions which were destined to add so much to the world’s store of knowledge of the Arctic seas. Baffin, who was described by Sherard Osborn as “the ablest, the prince of Arctic navigators,” was in 1615 appointed by the Merchants Adventurers pilot and associate to Richard Bylot, of the _Discovery_, which was now to make her fourth voyage in search of the North-West Passage. Making first for Hudson Strait, they soon discovered that they were being led into a blind alley. As the conditions, however, did not permit them to extend their voyage much that season, they were obliged to return home. In the following year, however, they were sent out once more by the Merchants Adventurers, and on this occasion they determined to push on north along the coast of Greenland. On May 30 they reached Sanderson’s Hope, Davis’s farthest point, and there they entered upon an entirely new field of discovery. With such energy did they apply themselves to the work that they had crossed Melville Bay by the beginning of June, and were sailing merrily on their way past Cape York, Cape Dudley Digges, and Whale Sound. At last, when they had exceeded Davis’s farthest north by over three hundred miles, their triumphant career was stopped at the entrance to Smith Sound, within sight of Cape Alexander. This latitude, 77° 45′, remained unequalled for over two centuries. Unable to proceed any further to the north, Baffin and Bylot determined to sail south-west, and to see if they could not add to their growing list of discoveries on their homeward journey. Their hopes were amply fulfilled, for on July 12 they found themselves off the entrance to Lancaster Sound, which was the gate, as it afterwards proved, to the North-West Passage. The ice, unfortunately, did not permit them to enter the Sound, so they made for the coast of Greenland, where they rested their men prior to their return to England. For the next hundred years or so very little was done in the way of Arctic discovery. A Dane of the name of Jens Munk started out to seek for the North-West Passage, and succeeded in making a few discoveries in Hudson’s Bay. In 1631, again, Captain Luke, alias “North-West,” Fox sallied forth on the same mission, bearing with him an epistle from the King of England to the Emperor of Japan, which, however, remained undelivered. The work which he did was not of much value, but he made up for this deficiency by writing a very humorous account of his experiences. Captain James, who went exploring in the same year, seems to have been dogged by ill-luck from the beginning to the end of his voyage, and Barrow describes his narrative of it as “a book of lamentation and weeping and great mourning.”
