"It is strange that I never heard father speak of any Aleck Fifield," thought Winn. He was about to ask some more questions, but was restrained by the remembrance of his present peculiar position. The same thought checked his inclination to say, "I am Winn Caspar, sir, the son of your friend Major Caspar, of Caspar's Mill." Instead of that he said to himself, "I will wait until we get away from this place; or, at any rate, until I can receive a letter from home that will prove who I am. Otherwise he might find out about the Sheriff's skiff, and think I had made up the story to escape arrest as a thief." So Winn held his peace, and only asked his host if he would furnish him the materials for writing a letter home. Provided with these, he wrote to his mother as follows: "MANDRAKE, IOWA. "MY OWN DEAR MOTHER,--I write to you instead of to father, as I suppose he must be somewhere on the river hunting for me by this time, though I have not seen him yet. "I am all right, and having a fine time, but have lost the raft. I am on board a boat called the _Whatnot_, with some very kind people--a gentleman named Fifield, a girl named Sabella, a funny old darky named Solon, and a monkey named Don Blossom. I am bound to find the raft again if it is still afloat, and am going to keep on down the river in this boat until we catch up with it. "I shall be here long enough for you to answer this letter; and send me some money, please, and tell me all about everybody. Give my dear love to Elta, and tell her I wish she knew Sabella and Don Blossom. She is just the kind of a girl, and he is just the kind of a monkey, a fellow likes to know. "Now it is late, and I must turn in, for I am working my passage on this boat, and Solon and I must take the place of a mule to-morrow, and till we can earn money enough to buy one. So good-bye, from your affectionate son,----WINN." While the boy was writing, Cap'n Cod went ashore, and when the former took his letter to the post-office, he met his host there with two letters in his hand. They followed Winn's into the box, but he did not see the address on either of them. If he had, he would have been more troubled than ever, for one was addressed to the Sheriff of Dubuque County, and the other to his own father. The old man had seen and recognized the skiff that he had built for Sheriff Riley as it lay tied to the wharf-boat, but had thought it best to keep this discovery to himself until he could communicate with its owner. By cautious inquiries he learned that the skiff had been left there by a young man calling himself Brackett, who had gone on down the river, but was expected back in a day or two. Cap'n Cod would have telegraphed to Sheriff Riley but for the fact that the wires had not yet been extended to Mandrake. So he wrote and begged the Sheriff to hasten down the river by first boat.
