It is already well known to those who take an interest in Arctic discovery, that the Hudson's Bay Company intended fitting out an expedition in 1840, which was to have proceeded to the northern shores of America by Back's Great Fish River, for the purpose of tracing the coast between the river Castor and Pollux of Dease and Simpson, and the Strait of the Fury and Hecla, as it was then very generally supposed that Boothia was an island. The party was to have been commanded by that able and enterprising traveller, Mr. Thomas Simpson, whose indefatigable exertions, in conjunction with those of Mr. Dease, had during the three preceding years effected so much; but his untimely and melancholy fate prevented that intention from being carried into effect, and the survey of the Arctic coast was discontinued for a few years. When it was determined that the survey should be resumed, Sir George Simpson, Governor-in-Chief of the Company's territories, informed me that a boat expedition to the Arctic Sea was again contemplated, at the same time doing me the honour of proposing that I should take command of it,--a charge which I most joyfully accepted. The plan of the expedition was different from any that had hitherto been adopted, and was entirely of Sir George Simpson's forming. Its leading features were as follows:--A party of thirteen persons, including two Esquimaux interpreters, was to leave Churchill in two boats at the disruption of the ice, and coast along the western shore of Hudson's Bay to the northward as far as Repulse Bay; or, if thought necessary, to the Strait of the Fury and Hecla. From this latter point the shore of the Arctic Sea was to be traced to Dease and Simpson's farthest discoveries eastward; or, if Boothia Felix should be found to form part of the American continent, up to some place surveyed by Captain or Commander (now Sir John and Sir James C.) Ross. I started from the Sault de S^{te.} Marie in the latter part of July, 1845, in a canoe which I took on with me as far as Red River, where this frail vessel was changed for a boat, which is better adapted for traversing large sheets of water. We had rather a stormy passage to Norway House, at which place five men were engaged for the expedition; and having brought two with me from the southern department, I required only three more, who I knew could easily be procured at York Factory.
