Note 41 — SKETCHES IN CANADA, (continued 6)
Reading edition
"The total descent of the Fall of St. Mary's has been ascertained to be twenty-two and a half perpendicular feet. It has been found impracticable to ascend the rapid; but canoes have ventured down, though the experiment is extremely nervous and hazardous, and avoided by a portage, two miles long, which connects the navigable parts of the strait."—Bouchette's Canada.
