Dr. Richard King, who had been Back's assistant and surgeon, now endeavoured to organize an expedition to the Arctic Ocean by way of Lake Athabasca and through a chain of lakes leading to the Great Fish River. This project received no backing from the British Government or from the Hudson's Bay Company. The Company now undertook to carry out an expedition of its own. The reasons of this are stated to have been--(1) The interest of the British public in the effort to connect the discoveries of Captains Back and Ross; (2) They are said to have desired a renewal of their expiring lease for twenty-one years of the trade of the Indian territories; (3) The fact was being pointed out, as in former years, that their charter required the Company to carry on exploration. In 1836 the Hudson's Bay Company in London decided to carrying out the expedition, and gave instructions to Governor Simpson to organize and despatch it. At Norway House, at the meeting of the Governor and officers of that year, steps were taken to explore the Arctic Coast. An experienced Hudson's Bay Company officer, Peter Warren Dease, and with him an ardent young man, Thomas Simpson, a relation of the Governor, was placed in charge. The party, after various preparations, including a course of mathematics and astronomy received by Thomas Simpson at Red River, made its departure, and Fort Chipewyan was reached in February, where the remainder of the winter was spent. As soon as navigation opened, the descent of the Mackenzie River was made to the mouth. The party then coasting westward on the Arctic Ocean, passed Franklin's "Return Reef," reached Boat Extreme, and Simpson made a foot journey thence to Cape Barrow. Having returned to the mouth of the Mackenzie River, the Great Bear Lake, where Fort Confidence had been erected by the advance guard of the party, was reached. The winter was passed at this point, and in the following spring the expedition descended the Copper-mine River, and coasting eastward along the Polar Sea, reached Cape Turnagain in August. Returning and ascending the Coppermine for a distance, the party halted, and Simpson made a land journey eastward to new territory which he called Victoria Land, and erected a pillar of stones, taking possession of the country, "in the name of the Honourable Company, and for the Queen of Great Britain." Their painful course was then retraced to Fort Confidence, where the second winter was spent. On the opening of spring, the Company descended to the coast to carry on their work. Going eastward, they, after much difficulty, reached new ground, passed Dease's Strait, and discovered Cape Britannia.
