It was on a morning in early spring that our four adventurers found themselves at the side of their boat, which rested on the bank of the great Missouri River, not far above its mouth. Their little tent stood, ready for striking, and all their preparations for the start now were made. Rob stood with a paint pot and brush in hand, at the bow of the boat.

“She’s dry, all right, by now, I think,” said he. “If we put a name on the stern board the paint could dry without being touched. What shall we christen her?”

“Call her ‘Liberty,’” suggested Jesse, “or, say, ‘America.’”

“Fine, but too usual. Give us a name, John.”

“Well, I say, ‘Columbia,’ because we are headed for the Columbia, the same as Lewis and Clark.”

“Too matter-of-fact! Give us a jollier name.”

“Well, give us one yourself, Rob,” said Uncle Dick, “since you’re so particular.”

“All right! How’d ‘Adventurer, of St. Louis,’ do?”

“Not so bad—not so bad. But to Lewis and Clark, St. Louis was only one point of their journey, important as it was.”

“I’ll tell you,” broke in Jesse, the youngest. “Call her ‘Adventurer, of America.’ You can paint it all on, if you use small letters for part, like the steamboats.”

“That’s the name!” said Rob. “Because that was a great adventure that Lewis and Clark were taking on; and it was all for America—then and now. Hard to live up to. But, you see, we’re only following.”

“What do you say, Uncle Dick?” asked John.

“I like it,” replied the latter. “It will do, so paint it on, Rob; and all of you be careful not to smudge it. It’ll be dry by to-morrow morning, for this fantail rides high above the motors.

“Finish drying and packing the dishes now, and let’s be off when Rob gets done. We’re exactly one hundred and eighteen years to a day and an hour after the boats of Lewis and Clark at this very place—only, Lewis went across by land to St. Charles, and saved a little of his time by meeting the boats there.”

“And that was the real start, wasn’t it, Uncle Dick?” demanded Frank.

“In a way, yes. But over yonder, across the Mississippi, on the river Du Bois, in the American Bottoms, Will Clark had built the cabins for the men’s winter quarters. And long before that, Meriwether Lewis had left Washington after saying good-by to Mr. Jefferson. And then he stopped awhile near where Pittsburgh is, to get his boats ready to go down the Ohio, and get men. And then he picked up Clark where Louisville now is. And then he left the Ohio River and crossed by horseback to the Army post across from here, to get still more men for the expedition—soldiers, you see, good hardy men they were, who knew the backwoods life and feared nothing. So after they got all of the expedition together, they made winter quarters over yonder, and in the spring they came over here, and the great fleet of three boats and forty-five men started off on their adventure.

“Of course, Rob, you know the incident of the Three Flags?”

Rob nodded.

“That was a great day, when the American army of the West, twenty-nine men in buckskin, under this young captain of thirty years, marched into St. Louis to take possession of the Great West for America. And St. Louis in twenty-four hours was under the flags of three great countries, Spain, France, and the United States.

“You see—and I want you to study these things hard some day—Napoleon, the Emperor of France, was at war. This Western region belonged to Spain, or she said it did, but she ceded it to Napoleon; and then when he didn’t think he could hold it against Great Britain, he sold it to us.

“Now this had all been country largely settled by French people who had come down long ago from the Great Lakes. They didn’t think Spain had exercised real sovereignty. Now we had bought up both claims, the Spanish and the French; so we owned St. Louis all right, going or coming.

“So, first the Spanish flag over the old fort was struck. Next came the French. And the French loved the place so much, they begged they might have their flag fly over it for at least one night. Captain Lewis said they might, for he was a courteous gentleman, of course. But orders were orders. So in the morning the flag of France came down and the Flag of the United States of America was raised, where it has been ever since, and I think will always remain. Those events happened on March 9 and 10, 1804.

“So there they were, with the Flag up over a country that nobody knew anything at all about. Then they started out, on May 14 of that year, 1804. And since that time that unknown America has grown to be one of the richest, if not the very richest, land in the world. And since that time, so much has the world changed, I have seen three flags flying at the same time over a city in France—those of France, of Great Britain, and of America, and all at peace with one another, though all at war together as allies in a cause they felt was just. May they float together now! Aye, and may Spain have no fear of any of the three.”

“Are you about done with the painting, Rob?” concluded Uncle Dick.

“Yes, sir, finished.”

“Look it!” said John.

Jesse was coming down from the tent, unrolling something wrapped around a stick. “Well now, well now,” he drawled, “where shall I put this?”

“Company, ’tenshun!” barked Uncle Dick. “Colors pass!” And all snapped again into the salute while Jesse fastened the Flag into the bow of the Adventurer, of America.

“Now we’re about all ready,” said Jesse, gravely. And he also stood at the salute which good Scouts give the Flag, as a little band of strong men in buckskin had done, not far away, more than a hundred years ago.
