It must be remembered that while Winn would have recognized Mr. Gilder, he had not seen the other "river-traders," Plater and Grimshaw. Of these two, the former had not set eyes on the lad whose raft they had stolen; but the latter had caught a glimpse of him, and now, as he noted Winn's startled glance into the interior of the "shanty," it flashed into his mind who this intrusive boy was.

The "river-traders" had not really expected Winn to follow them. They imagined that after he escaped from the island, which they hoped he would not do for several days, he would be glad enough to make the best of his way home. Still, they had taken the precaution of disguising the Venture by throwing the wheat overboard, tearing down the buildings in which it had been stowed, and erecting a tent in place of one of them. As they were well provided with various changes of wigs and beards, they felt quite safe until Billy Brackett boarded the raft for the second time, and made inquiries for one having three "shanties." Then they realized that a search was being made for them, or, at least, for the craft from which they were operating.

They felt somewhat easier when one of their number, detailed to watch the movements of their unwelcome visitor, returned and reported that he had gone back up the river. Still, they thought it well to again alter the appearance of the raft by removing the tent, and so lengthening the "shanty" as to materially change its aspect. They also allowed the raft to drift night and day for nearly five hundred miles without a pause. Then, again feeling safe from pursuit, they tied up just below the City of Alton, Illinois, and prepared to resume their dishonest business.

Their plan of operations was to purchase goods wherever they stopped, but always in such small quantities that for the bills they tendered in payment they received a certain amount of good money in change. A little farther along they would offer the goods thus accumulated for sale so cheaply that they readily disposed of them. In this way they not only did a thriving business, but kept up the appearance of being what they claimed to be—"river-traders" and raftsmen.

In this wicked scheme of cheating and stealing, Plater and Grimshaw felt no scruples nor regrets; but with Mr. Gilder, especially after his meeting with Sabella, the case was different. He was a man of gentlemanly instincts, and was a skilful engraver, who had worked in the Government Printing-office at Washington for several years. There he was extravagant, got into debt, yielded to the temptation to make a fortune easily, and became a counterfeiter. The present undertaking was his first experience in that line of wickedness, and he was already heartily sick of it. While on the island, where his part of the work was engraving and printing, he had not realized the contemptible nature of his unlawful business. He had merely been filled with pride in his own skill, which feeling his associates took good care to encourage by artful praise.

When he met Sabella, it flashed across him for the first time that his own little girl, far away in an eastern city, was the daughter of a criminal, and from that moment he was a changed man. Through the long days and longer nights, as the raft drifted down the great river, these thoughts were ever with him: "What will she say when she finds it out? How will she act? Will she ever kiss me, or even speak to me again? I have made her very name a disgrace. What shall I do to wipe it out? What shall I do?"

His companions noticed his strange mood, and jeered at him, but failed to change it. Finally they became suspicious, and held secret consultations as to how they should rid themselves of him. They finally determined to accomplish this in some way at St. Louis, and so matters stood when they made their stop at Alton. Here they intended remaining until they had transacted a satisfactory amount of business. Thus, on the foggy morning following Don Blossom's escape from the Whatnot, Messrs Gilder and Plater had gone into the town to familiarize themselves with its localities, while Grimshaw was left to look out for the raft. Now Winn Caspar had accidentally discovered it, and recognized it as the Venture.

He did not know the man standing in the doorway and looking so curiously at him, nor did he suppose himself known by the other. So, with a great effort, he strove to conceal the tumult of his feelings, and to appear natural and self-possessed. He answered the man's curt inquiry regarding his business there by saying, in as pleasant a tone as he could command, that he was searching for a lost monkey, which he thought might have taken to the timber beside which this raft was moored. "You startled me by throwing open your door so suddenly just as I was about to knock," he continued; "but you haven't seen anything of a stray monkey this morning, have you?"

"Not until this moment," answered the man, surlily, "and I don't want to see any more of him. Good-day."

With this he slammed the door in the boy's face, and then, stealing on tiptoe to a window, watched for his departure from the raft.
