- ularly Mr. {287} Regis Bruguier, who had ascended that river
to its source, informed me that it came out of two small lakes, not far from the chain of the Rocky Mountains, which, at that place, diverges considerably to the east. According to Arrowsmith's map, the course of the Tacoutche Tessé, from its mouth in the Pacific Ocean, to its source in the Rocky mountains, is about twelve hundred English miles, or four hundred French leagues of twenty-five to a degree; that is to say, from two hundred and forty to two hundred and eighty miles from west to east, from its mouth to the first falls: seven hundred and fifty miles nearly from S.

We were not provided with the necessary instruments to determine the latitude, and still less the longitude, of our different stations; but it took us four or five days to go up from the factory at Astoria to the falls, and we could not have made less than sixty miles a day: and, as I have just {288} remarked, we occupied an entire month in getting from the falls to Canoe river: deducting four or five days, on which we did not travel, there remain twenty-five days march; and it is not possible that we made less than thirty miles a day, one day with another.[161]
We ascended Canoe river to the point where it ceases to be navigable, and encamped in the same place where Mr. Thompson wintered in 1810-'11. We proceeded immediately to secure our canoes, and to divide the baggage among the men, giving each fifty pounds to carry, includ-*
