My only mental picture of the site of Clark's shipyard was that received from the one hurried glance as I came to the upper rapid. There was no chance for a second look. Sentimentally I was sorry not to have been able to land and pretend to look for the stumps of the trees cut down for the dugouts. As a matter of fact, however, as the river had been altering its channel every season for over a hundred years, there was no question in my mind but that the shipyard flat had been made and washed out a score of times since Clark was there. Captain Clark's party spent four days building the two dugout canoes and exploring in this vicinity. Twenty-four of their horses were stolen by Indians and never recovered. The same fate ultimately overtook the remainder of the bunch, which Sergeant Pryor and two others were attempting to drive overland to the Mandan villages on the Missouri. Clark described the canoes as "twenty-eight feet long, sixteen or eighteen inches deep and from sixteen to twenty-four inches wide." Lashed together, these must have made a clumsy but very serviceable craft. Considering its weight and type, their first-day run in it--from Rapids to the mouth of Pryor's Fork, near Huntley--strikes me as being a remarkable one. The Captain's actual estimates of distances on this part of his journey are much too high and also present many discrepancies. This particular run, however, is easy fixable by natural features. It must be very close to sixty miles as the river winds, possibly more. It is not fair to compare this with the considerably faster time I made over similar stretches of the Yellowstone. I had considerably higher and swifter water and a boat so light that no delays from shallows and bars were imposed. Very generally speaking, I found my rate of travel on the Yellowstone to have worked out about twenty-five per cent. faster than that of Clark's party. On the Missouri, on stretches where I did not use my outboard motor, I averaged just about the same as the united explorers on their down-stream voyage. There is little doubt that they stopped longer and oftener than I did on the Missouri, and that while on the river their big crews snatched along whatever type of craft they happened to be manning at a considerably faster rate than I pulled. By and large, however, I should say that Kipling's "Down to Gehenna or up to the Throne, He travels the fastest who travels alone," holds quite as good on the Running Road as in Life's Handicap.
