Up rose the gangplank. The engine bell jangled. The negro roustabouts cast off the bow and stern hawsers from the wharf posts, and scrambled over the gunwale as the _Robert Burns_ began to back out into the stream. Mrs. Adams waved her handkerchief. Everybody on the wharf waved--mostly handkerchiefs, which were suddenly very popular. The people on board waved back--and they, too, used handkerchiefs pretty generally. Faster and farther backed the _Robert Burns_, until in midcurrent, after describing a great half-circle, she was pointing down stream. The engine bell jangled to stop, and to go ahead--and she was started for New Orleans. They were off for California! The levee, with his mother's handkerchief now fading into the whitish blur of other handkerchiefs, drifted behind; Charley took a long breath, straightened his shoulders, stole a glance at his father, who was winking violently in queer fashion, and began to take stock of the other passengers. Some were leaving the rail; a number of others already had left it, and were negligently strolling about or seating themselves for comfort. They mostly were men--business men, planters, and the like, traveling down-river on pleasure or errands of importance, and a few miners bound for California. There was no Mr. Jacobs, that Charley knew, among them, and he felt easier. Probably "J. Jacobs" was some other Jacobs, and not the long-nosed man. "Let's go in and put our room to rights, Charley," proposed Mr. Adams, as the buildings of old St. Louis merged one with another, on the shore line behind. He briskly limped across the deck, and Charley followed. This would be something to do, at any rate. But as he passed the door of the long salon, or lounging room, he glanced in and saw clear to the other end, where there was a bar for sale of liquors. And he was certain that he glimpsed the long-nosed man, just coming from the bar! Charley's heart fairly skipped a beat. No, he would not say anything to his father, for perhaps he had been mistaken--and what was the sense in being scared? Supposing that was the long-nosed man. He was not bigger or smarter than they, and besides, as Mr. Adams had said, he had a perfect right to travel on the Mississippi River. Everybody used the river, because there were no railroads here. However, it was queer, his choosing this boat. Charley and his father set their state-room in order, by arranging their clothes and sleeping things. "You can go out, if you want to, Charley," spoke his father. "I've got a little more to do, yet. Then I'll come, too." "All right," and away clumped Charley, in his heavy boots. This time he was determined to look in earnest for the long-nosed man. He hoped that he would not find him, but he feared, just the same.
