But the wagon still stands at the door. We ought to start at 8 30 A.M.; we are detained an hour while last words are said, and adieu—a long adieu—is bidden to joke and julep, to ice and idleness. Our “plunder” is clapped on with little ceremony; a hat-case falls open—it was not mine, gentle reader—collars and other small gear cumber the ground, and the owner addresses to the clumsy-handed driver the universal G— d—, which in these lands changes from its expletive or chrysalis form to an adjectival development. We try to stow away as much as possible; the minor officials, with all their little faults, are good fellows, civil and obliging; they wink at non-payment for bedding, stores, weapons, and they rather encourage than otherwise the multiplication of whisky-kegs and cigar-boxes. We now drive through the dusty roads of St. Jo, the observed of all observers, and presently find ourselves in the steam ferry which is to convey us from the right to the left bank of the Missouri River. The “ Big Muddy,” as it is now called—the Yellow River of old writers—venerable sire of snag and sawyer, displays at this point the source whence it has drawn for ages the dirty brown silt which pollutes below their junction the pellucid waters of the “Big Drink.’ It runs, like the lower Indus, through deep walls of stiff clayey earth, and, like that river, its supplies, when filtered (they have been calculated to contain one eighth of solid matter), are sweet and wholesome as its brother streams. The Plata of this region, it is the great sewer of the prairies, the main, channel and common issue of the water-courses and ravines which have carried on the work of denudation and degradation for days dating beyond the existence of Egypt.

According to Lieutenant Warren, who endorses the careful examinations of the parties under Governor Stevens in 1858, the Missouri is a superior river for navigation to any in the country, except the Mississippi below their junction. It has, however, serious obstacles in wind and frost. From the Yellow Stone to its mouth, the breadth, when full, varies from one third to half a mile; in low water the width shrinks, and bars appear. Where timber does not break the force of the winds, which are most violent in October, clouds of sand are seen for miles, forming banks, which, generally situated at the edges of trees on the islands and points, often so much resemble the Indian mounds in the Mississippi Valley, that some of them—for instance, those described by Lewis and Clarke at Bonhomme Island — have been figured as the works of the ancient Toltecs. It would hardly be feasible to correct the windage by foresting the land. The bluffs of the Missouri are often clothed with vegetation as far as the debouchure of the Platte River. Above that point the timber, which is chiefly cotton-wood, is confined to ravines and bottom lands, varying in width from ten to fifteen miles above Council Bluffs, which is almost continuous to the mouth of the James River. Every where, except between the mouth of the Little Cheyenne and the Cannon Ball rivers, there is a sufficiency of fuel for navigation; but, ascending above Council Bluffs, the protection afforded by forest growth on the banks is constantly diminishing. ‘The trees also are injurious; imbedded in the channel by the “caving-in” of the banks, they form the well-known sawyers, or floating timbers, and snags, trunks standing like chevaua de frise at various inclinations, pointing down the stream. From the mouth of the James River down to the Mississippi, it is a wonder how a steamer can run: she must lose half her time by laying to at night, and is often delayed for days, as the wind prevents her passing by bends filled with obstructions. The navigation is generally closed by ice at Sioux City on the 10th of November, and at Fort Leavenworth by the 1st of December.  The rainy season of the spring and summer commences in the latitude of Kansas, Missouri, Iowa, and Southern Nebraska, between the 15th of May and the 30th of June, and continues about two months. The floods produced by the melting snows in the mountains come from the Platte, the Big Cheyenne, the Yellow Stone, and the Upper Missouri, reaching the lower river about the 1st of July, and lasting a month. Rivers like this, whose navigation depends upon temporary floods, are greatly inferior for ascent than for descent. The length of the inundation much depends upon the snow on the mountains: a steamer starting from St. Louis on the first indication of the rise would not generally reach the Yellow Stone before low water at the latter point, and if a miscalculation is made by taking the temporary rise for the real inundation, the boat must lay by in the middle of the river till the water deepens.

Some geographers have proposed to transfer to the Missouri, on account of its superior length, the honor of being the real head of the Mississippi; they neglect, however, to consider the direction and the course of the stream, an element which must enter largely in determining the channels of great rivers. It will, I hope, be long before this great ditch wins the day from the glorious Father of Waters.
