"Well, Captain Meriwether Lewis was not born on this day," said his uncle, "but his birthday was celebrated on this spot by his party, on August 18, 1805, and they celebrated it with a dance, and an 'extra gill of whiskey.'" "We'll issue an extra gill of marmalade to the men to-night, and conclude our day of hard travel with a 'Descharge of the Bow piece,' just because it's the Fourth of June. We're hitting things off in great style now, and I'm beginning to have more confidence in gasoline." "What made you want to get to this place, Uncle Dick?" asked John, his own mouth rather full of fried chicken. "Because of the location--the mouth of the Sioux River, and at the lower edge of the great Sioux nation. "Lewis and Clark tried to get peace among all these river tribes. They held a big council here, decorating a few more Otoes and Missouris, and telling them to make peace with the Omahas and the Pawnee Loups. The Sioux had not yet been found, though their hunting fires were seen all through here, and Lewis was very anxious to have his interpreter, Dorion, find some Sioux and bring them into council. "It was at Captain Lewis's birthday party that the first and only casualty of the trip ensued. You remember Sergeant Floyd--he spelled worse than Clark, and Ordway worse than either--and his journal of some twenty thousand words, which he had kept till now? Well, he danced hard at the birthday party or at the Indian council, and got overheated, after which he lay down on the damp sand and got chilled. It gave him what the _Journal_ calls a 'Biliose Chorlick,' and on the second day he died. He was buried on the bluffs below the town, at what still is called Floyd's Bluff, on the river they named after him, with military honors, and his grave long was known. His river still is known by his name, and it runs right into the town of Sioux City. The river washed the bank away under his grave, and in 1857 the remains were reburied, back from the river. That spot was marked by a slab in 1895, and a monument was put over it in May, 1901. I was a guest at the dedication of that obelisk. It was erected under the supervision of General Hiram Chittenden, the great engineer and great historian. It has a city park all of its own, and a marvelous landscape it commands. "Well, poor Floyd had no memorial in those rude days, beyond a 'seeder post.' They did what they could and then they 'set out under a gentle Breeze and proceeded on.'" "Well, but Dorion knew this country, then?" John began again, after a time.
