"But when did they first find the buffalo?" demanded Jesse, fingering once more the little rifle which always lay near him in the boat. "Gee! now, I'd like to kill a buffalo!" "All in due time, all in due time, Jess!" his leader replied. "My, but you are bloodthirsty! Wait now till August 23d, above Sioux City. You are Captain William Clark, with your elk-hide notebook inside your shirt front, and you have gone ashore and have killed a fat buck. And when you get back to the boat J. Fields comes in and says he has killed a buffalo, in the plain ahead; and Lewis takes twelve men and has the buffalo brought to the boat at the next bend; so you just make no fuss over that first buffalo, and set it down in your elk-hide book. And that same day two elk swam across the river ahead of the boat. And that same evening R. Field brought in two deer on a horse, and another deer was shot from the boat; and they all saw elk standing on a sand bar, and several prairie wolves. And the very next day, don't you remember, you saw great herds of buffalo? Oh, now you're in the Plains! Everybody now is 'jurking meat.' What more do you want, son?" "Aw, now!" said Jesse. "Well, anyway, we're about in town." CHAPTER XI AMONG THE SIOUX "Now we are leaving the Pawnees and passing into the Sioux country!" said Rob. They were passing under the great railroad bridge which connected Council Bluffs, Iowa, with Omaha, Nebraska. The older member of the party nodded gravely. "And can't you see the long lines of the white-topped covered wagons going west--a lifetime later than Lewis and Clark, when still there was no bridge here at all? Can't you see the Mormons going west, with their little hand carts, and their cows hitched up to wagons with the oxen? Look at the ghosts, Rob! Hit her up. Let's get out of here!" "She's running fine," Rob went on. "Somehow I think this must be better water, above the Platte. You know, Lewis and Clark only averaged nine miles a day, but along in here for over two hundred miles they were beating that, doing seventeen and one-quarter, twenty and one-quarter, seventeen, twenty-two and one-half, seventeen and one-half, sixteen, seventeen, twenty and one-half, twenty and one-half, fifteen, ten and three-quarters, fifteen, ten--not counting two or three broken days. They seem to have got the hang of the river, somehow." "So have we," nodded the other. "I'll give you five days to make Sioux City." As a matter of fact, the stout little ship _Adventurer_ now began to pick up on her own when they had passed that Iowa city, going into camp on the evening of June 4th well above the town. They purchased bread, poultry, eggs, and butter of a near-by farmer, and opened a jar of marmalade for Jesse, to console him for the lack of buffalo. "It's my birthday, too, to-day," said Jesse. "I was born on the fourth day of June, fourteen years ago. My! it seems an awful long time."
