other observations that might be likely to tend to the further development of its cause, and the laws by which it is governed. Mr. Back and Mr. Hood were to assist me in all the observations above-mentioned, and to make drawings of the land, of the natives, and of the various objects of natural history; and, particularly, of such as Dr. Richardson, who, to his professional duties, was to add that of naturalist, might consider to be most curious and interesting. I was instructed, on my arrival at, or near, the Mouth of the Copper-Mine River, to make every inquiry as to the situation of the spot whence native copper had been brought down by the Indians to the Hudson's Bay establishment, and to visit and explore the place in question; in order that Dr. Richardson might be enabled to make such observations as might be useful in a commercial point of view, or interesting to the science of mineralogy. From Joseph Berens, Esq., the Governor of the Hudson's Bay Company, and the gentlemen of the Committee, I received all kinds of assistance and information, communicated in the most friendly manner previous to my leaving England; and I had the gratification of perusing the orders to their agents and servants in North America, containing the fullest directions to promote, by every means, the progress of the Expedition. I most cheerfully avail myself of this opportunity of expressing my gratitude to these Gentlemen for their personal kindness to myself and the other officers, as well as for the benefits rendered by them to the Expedition; and the same sentiment is due towards the Gentlemen of the North-West Company, both in England and America, more particularly to Simon McGillivray, Esq., of London, from whom I received much useful information, and cordial letters of recommendation to the partners and agents of that Company, resident on our line of route. A short time before I left London I had the pleasure and advantage of an interview with the late Sir Alexander Mackenzie, who was one of the two persons who had visited the coast we were to explore. He afforded me, in the most open and kind manner, much valuable information and advice. The provisions, instruments, and other articles, of which I had furnished a list, by direction of the Lords Commissioners of the Admiralty, were embarked on board the Hudson's Bay Company's ship Prince of Wales, appointed by the committee to convey the Expedition to York Factory, their principal establishment in Hudson's Bay.
