The work done by Lieutenant Lefroy was of the most accurate and valuable kind. His name is remembered as that of one of the most trustworthy of the explorers of the plains of Rupert's Land and the North, and is commemorated by Fort Lefroy in the Rocky Mountains. It is true his evidence, recorded in the Blue Book of 1857, was somewhat disappointing, but his errors were those of judgment, not of prejudice or intention. PALLISER AND HECTOR. The approach of the time when the twenty-one years' lease of the Indian territories granted by the Imperial Parliament to the Hudson's Bay Company was drawing near a close in 1857, when the Committee of the House of Commons met in February of this year to consider the matter. A vast mass of evidence was taken, and the consideration of the Blue Book containing this will afford us material for a very interesting chapter. The interest in the matter, and the necessity for obtaining expert information, led the Imperial Government to organize an expedition under Captain John Palliser, R.N.A., of the Royal Engineers. With Captain Palliser, who was to go up the Canadian lakes to the interior, was associated Lieutenant Blakiston, R.N., who received orders to proceed by ship to York Factory and meet the main expedition at some point in Rupert's Land. The geologist of the expedition was James Hector, M.D. (Edin.). J. W. Sullivan was secretary and M. E. Bourgeau, botanist. After the usual incidents of an ocean voyage, some difficulty with the Customs authorities in New York arose as to the entry of astronomical instruments, which was happily overcome, and after a long journey by way of Detroit, Sault Ste. Marie was reached, where Palliser found two birch bark canoes and sixteen voyageurs awaiting him, as provided by the Hudson's Bay Company. Sir George Simpson had lately passed this point. Journeying along the fur traders' route, the explorers found themselves expected at Fort Frances, on Rainy River. Here a deputation of Indians waited upon them, and the old chief discoursed thus: "I do not ask for presents, although I am poor and my people are hungry, but I know you have come straight from the Great Country, and we know that no men from that country ever came to us and lied. I want you to declare to us truthfully what the Great Queen of your country intends to do to us when she will take the country from the fur company's people. All around me I see the smoke of the white men to rise. The 'Long Knives' (the Americans) are trading with our neighbours for their lands and they are cheating them and deceiving them. Now, we will not sell nor part with our lands."
