On December 10th Pike started on a journey northward in sleds, taking a canoe with him for use so soon as the river should open. When Pike arrived near Red Cedar Lake, he was met by four Chippewa Indians, a Frenchman, and one of the North-West traders, named Grant. Going with Grant to his establishment on the shores of the lake, Pike tells us, "When we came in sight of the house I observed the flag of Great Britain flying. I felt indignant, and cannot say what my feelings would have excited me to had Grant not told me that it belonged to the Indians." On February 1st Pike reached Leech Lake, which he considered to be the main source of the Mississippi. He crossed the lake twelve miles to the establishment of the North-West Company, which was in charge of a well-known North-West trader, Hugh McGillies. While he was treated with civility, it is plain from his cautions to McGillies and his bearing to him, that he was jealous of the influence which British traders were then exercising in Minnesota. Having made a treaty with the Chippewa Indians of Red Lake, Pike's work was largely accomplished, and in April he departed from this region, where he had shown great energy and tact, to give in his report after a voyage of some nine months. A most melancholy interest attaches to this gentlemanly and much-respected officer of the United States. In the war of 1812-15, Pike, then made a general, was killed at the taking of York (Toronto), in Upper Canada, by the explosion of the magazine of the fort evacuated by General Sheaffe. Pike, as leader on this Mississippi expedition, as commanding an expedition on the Rio Grande, where he was captured by the Spaniards, and as a brave soldier, has handed down an honourable name and fame. LONG AND KEATING. The successful journey of Lewis and Clarke, as well as the somewhat useful expedition of Lieutenant Pike, led the United States Government to send in 1823 an expedition to the northern boundary line 49 deg. N., which had been settled a few years before. In charge of this was Major Stephen H. Long. He was accompanied by a scientific corps consisting of Thomas Say, zoologist and antiquary; Samuel Seymour, landscape painter and designer; and William H. Keating, mineralogist and geologist, who also acted as historian of the expedition.
