"I can't bear to hear you talk so, husband," said Mrs. Caspar. "As if our Winn wouldn't be more readily influenced by his own father and mother than by any one else in the world! At the same time, I think William's plan well worth considering, for I have hated the idea of that raft trip for you. I have dreaded being left alone here with only Elta, too, though I wouldn't say so when I thought there wasn't anything else to be done." With this unanimous acceptance of the young engineer's plan, it took but a short time to arrange its details, and before dark everything was settled. The Major was to leave for Madison the next morning, while Billy Brackett was to start down the creek that very evening, so as to be ready at daylight to begin his search for the missing raft at the point where it had been last reported. By his own desire he was to go alone in the skiff, except for the companionship of his trusty Bim, who made a point of accompanying his master everywhere. The young man was provided with an open letter from Major Caspar, giving him full authority to take charge of the raft and do with it as he saw fit. Both Mrs. Caspar and Elta wrote notes to Winn, and gave them to Billy Brackett to deliver. The major also wrote a line of introduction to an old soldier who had been his most devoted follower during the war. He was now living with a married niece near Dubuque, Iowa, and might possibly prove of assistance during the search for the raft. Thus equipped, provided with a stock of provisions, and a minute description of both the raft and of Winn, whom he did not hope to recognize, the young engineer and his four-footed companion set forth soon after supper on their search for the missing boy. An hour later they too were being swept southward by the resistless current of the great river. CHAPTER V. HOW THE VOYAGE WAS BEGUN. When Winn Caspar turned into his comfortable bunk aboard the raft on the night of the storm, it never once occurred to him that the _Venture_ might float before morning. She never had floated, and she seemed so hard and fast aground that he imagined a rise of several feet of water would be necessary to move her. It had not yet rained where he was, and the thought that it might be raining higher up the stream did not enter his mind. So he went comfortably to bed, and slept like a top for several hours. Finally, he was awakened so suddenly that he sprang from the bunk, and by the time his eyes were fairly opened, was standing in the middle of the floor listening to a strange creaking and scratching on the roof above his head. It had aroused him, and now as he listened to it, and tried in vain to catch a single gleam of light through the intense darkness, it was so incomprehensible and uncanny, that brave boy as he was, he felt shivers creeping over his arms and back.
