"Then," said Billy Brackett, "the chain of evidence seems to be unbroken, incredible as it may appear, and it stretches from here straight away down the river—book coat, coat skiff, skiff raft, raft Winn. Now, in order to bring its ends together, and recover my long-lost nephew, I must again overtake that raft. I must start as soon as possible after breakfast, too. I don't know whether the game Winn and I are playing is blind-man's-buff or hide-and-seek, but it certainly resembles both."

Musing over this new aspect of the situation, the young engineer hastened back to his hotel and breakfast. In the dining-room, a few minutes later, a waiter was leaning over him, and asking, for the third time, "Tea or coffee, sir, an' how'll you have your eggs?" when the inattentive guest suddenly caused him to jump as though galvanized, by bringing his fist down on the table with a crash, and exclaiming, "No, by the great hornspoon, it can't be that way either! What's that you say? Oh yes, of course. Coffee, soft-boiled, and as quick as you can." Having delivered this order, the young man fixed his intent gaze on a brown spot ornamenting the table-cloth, and resumed his thinking.

It had just occurred to him that, according to all accounts, the raft from which he had taken that skiff had come down the river to this point two days before. So how could Winn Caspar, who had only escaped from the island a few minutes before he and Bim made good their own retreat, have reached the same place and joined that raft without attracting attention? Both the day and night watchmen at the wharf-boat had assured him that no such boy as he described had been seen on the water-front. They also said that the raft had been there all the day before, and that when it left it held only the three men who came with it. "Of course he might have been inside the 'shanty' when I was aboard, though I can't see how he got there, nor why he should join a strange raft anyway," argued the young man. "At any rate, it's my business to find out whether or not he is aboard it now. How about using the skiff, though? If it is the one Winn ran off with, it belongs to that Sheriff fellow. Like as not, he has already sent word down the river to have it picked up. In that case, if I was picked up in it, I might be accused of stealing it, which would never do in the world. No; to be on the safe side I must leave the skiff here, and take the first down-river steamboat that stops at this landing. First, though, I'll advertise for Winn in this town, and if I don't find him on the raft, there may be news waiting for me here when I come back."

This was the plan upon which the young engineer decided to act, and immediately after breakfast he proceeded to put it into execution.

There was no paper published in the place, but it did contain a makeshift sort of a printing-office, and towards this Billy Brackett directed his steps, after learning at what hour the next down-river boat was expected. Here he spent some time in composing a small circular, of which he ordered five hundred copies to be struck off, and distributed broadcast. His boat came along and he had to leave before this was ready for press; but he had engaged the services of his new acquaintance the night-watchman, who promised to place the bills wherever they would do good.

Poor Bim, tied up on the wharf-boat, and nearly heart-broken at his master's desertion, was also left in charge of this man. Billy Brackett was desirous of establishing friendly relations with the raftsmen when he should overtake them, and feared that would be impossible in case they should recognize him. This they would certainly do if he were accompanied by the bull-dog, whom one of them at least had reason to remember so well.

At another small landing, nearly a hundred miles farther down the river, Messrs. Gilder, Grimshaw, and Plater were rendered somewhat uneasy, late on the following day, by the appearance on board their raft of a young man who asked questions. Billy Brackett had experienced considerable difficulty in finding this raft, and was greatly disappointed that his search in this direction should prove fruitless. The raftsmen had never heard of Major Caspar, nor of Winn Caspar, his son. They were lumbermen from far up on the Wisconsin River, and were taking this raft to New Orleans as a speculation. They knew nothing of Sheriff Riley or his skiff. Yes, they had picked up an empty skiff two days before, but it had been taken away and another left in its place by a young fellow with a dog, who had boarded their raft without invitation, set his dog on one of them, and then skipped. They would like to meet that party again—yes, they would—and they'd make things pretty lively for him.

Then they began asking questions in turn, and assuming such a hostile tone that Billy Brackett concluded he might as well leave then as later. So, after asking them to keep a sharp lookout for a raft with three "shanties," two of which were filled with wheat, he bade them good-evening, and started back up the river by rail.

In the mean time the Whatnot had reached the town to which he was returning, and was now tied up just below the wharf-boat. It had been decided that the first exhibition of the "Floating Panoramic Show" should be given here, and Cap'n Cod went up into the town as soon as they arrived to have some bills printed. Winn, at the same time, started along the water-front to search for traces of his lost raft; and Sabella, who was very fond of dogs, went aboard the wharf-boat to make the acquaintance of a fine bull-dog she had noticed there as they passed.

At supper-time they all gathered again in the living-room of the Whatnot, where Sabella reported her new friend to be the most splendid bull-dog she had ever seen, and that his name was Bim.
