Note 165 — XXII

The following extract from a letter dated September, 1819, addressed by Mr. Austin to Mr. Schoolcraft, respecting the navigation of the Missouri, well portrays the impetuous character of that river. It shows, too, the great improvements in the steam-engine during the past twenty years.

"I regret to state that the expedition up the Missouri to the Yellow Stone has in part failed. The steamboats destined for the Upper Missouri, after labouring against the current for a number of weeks, were obliged to give up the enterprise. Every exertion has been made to overcome the difficulty of navigating the Missouri with the power of steam; but all will not do. The current of that river, from the immense quantity of sand moving down with the water, is too powerful for any boat yet constructed. The loss either to the government or to the contractor will be very great. Small steamboats of fifty tons burden, with proper engines, would, I think, have done much better. Boats like those employed, of twenty to thirty feet beam, and six to eight feet draught of water, must have uncommon power to be propelled up a river, every pint of whose water is equal in weight to a quart of Ohio water, and moves with a velocity hardly credible. The barges fixed to move with wheels, worked by men, have answered every expectation; but they will only do when troops are on board, and the men can be changed every hour."—Flagg.
