hundred miles and a map drawn from that chart is repro- duced herewith, taken from those in the original edition of Vancouver's "Voyage of Discovery."

The white men who next visited this part of the Columbia river came to it from the interior, the members of the Lewis and Clark Expedition in 1805-6. Captain William Clark was the engineer of that party and the maps drawn by him are remarkably accurate. These are contained in the Thwaites' Eldition of Lewis and Clark, published in 1904-5 by Dodd- Mead & Company. The river was at practically the same stage of water as in 1792, and it is not probable that many changes took place in the channel and shore line between 1792 and 1805-6, considering the few during the hundred years since that date. Lewis and Clark made no mention of Point Van- couver in their journals or maps.

The next record of the course of the Columbia river was that made by the famous astronomer and geographer of the Canadian "North- West Cc«npany," Mr. David Thompson, in 181 1, and shown on the wonderful map drawn by him in the years 1813-14, and printed in his "Narrative" recently pub- lished by the Champlain Society of Toronto, Canada. David Thompson's visit was in the summer during a period of ex- tremely high water; Celilo Falls were entirely submerged that year. He was conversant with the survey of Lieut. Broughton, for his journal entry of Saturday, July 13th, 181 1, written when camped just above Rooster Rock, reads: "Camped at 8:5 P. M. a little above Point Vancouver." And when returning up the river on Thursday, Jul. 25th, in com- pany with David Stuart, Alex. Ross and others of the Pacific Fur Company, he records: "middle of course turned N. E. ^ m. to a good campment at 7 P. M., fine meadow land below Point Vancouver." The fine meadows were at Washougal, Washington ; Mr. Thompson recorded the latitude and longi- tude of this encampment, but his map was too comprehensive to include mention of Point Vancouver.
