Taking it, then, for granted that the expedition entered Lancaster Sound, the most probable conjecture respecting the direction in which it advanced is that Sir John, literally following his instructions, did not stop to examine any openings either to the northward or southward of Barrow's Strait, but continued to push on to the westward until he reached Cape Walker in longitude 98°, when he inclined to the south-west, and steered as directly as he could for Beering's Straits. But even supposing that the state of the ice permitted him to take the desired route, and to turn to the south-westward by the first opening beyond the 98th meridian, we are ignorant of the exact position of that opening, the tract between Cape Walker and Banks's Land being totally unknown. That a passage to the southward does exist in that space, and terminates between Victoria and Wollaston Lands in Coronation Gulf, is inferred from the observed setting of the flood tide. There is, it is true, an uncertainty in our endeavours to determine the directions of the tides in these narrow seas, where the currents are influenced by prevailing winds; but Mr. Thomas Simpson, who was an acute observer, remarked that the flood tide brought much ice into Coronation Gulf round the west end of Victoria Land, and facts collected on three visits which I have made to that gulf lead me to concur with him. Entirely in accordance with this opinion is the fact noted by Sir Edward Parry, that the flood tide came from the north between Cornwallis and the neighbouring islands, and that the ice was continually setting round the west end of Melville Island and passing onwards to the south-east.
