One day in the midwinter of 1856 or 1857--I think it was 1856--I was coming along the main street of Keokuk in the middle of the forenoon. It was bitter weather--so bitter that that street was deserted, almost. A light dry snow was blowing here and there on the ground and on the pavement, swirling this way and that way and making all sorts of beautiful figures, but very chilly to look at. The wind blew a piece of paper past me and it lodged against a wall of a house. Something about the look of it attracted my attention and I gathered it in. It was a fifty-dollar bill, the only one I had ever seen, and the largest assemblage of money I had ever encountered in one spot. I advertised it in the papers and suffered more than a thousand dollars' worth of solicitude and fear and distress during the next few days lest the owner should see the advertisement and come and take my fortune away. As many as four days went by without an applicant; then I could endure this kind of misery no longer. I felt sure that another four could not go by in this safe and secure way. I felt that I must take that money out of danger. So I bought a ticket for Cincinnati and went to that city. I worked there several months in the printing-office of Wrightson and Company. I had been reading Lieutenant Herndon's account of his explorations of the Amazon and had been mightily attracted by what he said of coca. I made up my mind that I would go to the head waters of the Amazon and collect coca and trade in it and make a fortune. I left for New Orleans in the steamer "Paul Jones" with this great idea filling my mind. One of the pilots of that boat was Horace Bixby. Little by little I got acquainted with him, and pretty soon I was doing a lot of steering for him in his daylight watches. When I got to New Orleans I inquired about ships leaving for Para and discovered that there weren't any, and learned that there probably wouldn't be any during that century. It had not occurred to me to inquire about those particulars before leaving Cincinnati, so there I was. I couldn't get to the Amazon. I had no friends in New Orleans and no money to speak of. I went to Horace Bixby and asked him to make a pilot out of me. He said he would do it for a hundred dollars cash in advance. So I steered for him up to St. Louis, borrowed the money from my brother-in-law and closed the bargain. I had acquired this brother-in-law several years before. This was Mr. William A. Moffett, a merchant, a Virginian--a fine man in every way. He had married my sister Pamela, and the Samuel E. Moffett of whom I have been speaking was their son. Within eighteen months I became a competent pilot, and I served that office until the Mississippi River traffic was brought to a standstill by the breaking out of the civil war.
