By noon he was ready to depart from Dubuque, satisfied that there was no information to be gained in that place concerning either Winn or the raft. Although he was not discouraged, he was puzzled, and was even beginning to feel anxious at the strange aspect this affair of the lost _Venture_ was assuming. Until sunset he rowed steadily and swiftly downstream, hailing the ferrymen as he passed, and stopping at the settlements on both sides of the river to make inquiries. He also hailed passing boats, and boarded several rafts that he discovered tied to the western bank, but all in vain. He failed to learn anything about Winn, and heard that but one raft had passed down the river the day before. It was described as having a single "shanty," a tent, and a crew of three men. As that was not the kind of a raft he was looking for, this information only added to the young man's perplexity. It never occurred to him that the raft might have been stolen and disguised. So, as he was certain he had not passed it, there was but one solution to the problem. The _Venture_ must have been wrecked and gone to pieces during the storm of that first night, and Winn must have escaped to the island. Even with this explanation the mystery of Winn's second disappearance remained as great as ever, and by the time Billy Brackett hailed the _Whatnot_, as has already been noted, he was as thoroughly bewildered as ever in his life. Nor could he decide on any plan of action that seemed in the least satisfactory. He knew there was a town a mile or so below where the _Whatnot_ lay, and there he had determined to spend the night. But for his desire to reach this place before darkness should wholly shut in, he would have boarded the _Whatnot_ merely to gratify the curiosity excited by her strange appearance. As it was, he felt that he had no time to spare, and so hastened on. It was quite dark as he approached the lights marking the town he was seeking; but as he drew near he discovered what appeared like a part of the levee slowly moving out from shore. Above it rose dimly a white object that he had taken for a house, and still above this shown a lantern. In a moment he saw that it was a raft resuming its voyage down the river, and he determined to make an inquiry from its crew before landing.
