In other cases, of which at first I could not have imagined the possibility, my under-study was of use to me. I was invited to address my fellow townsmen and townswomen on the occasion of the centennial anniversary of the settlement of our village, and as I had discovered that Walkirk was a good reader I took him with me, in order that he might deliver my written address in case my courage should give out. My courage did not give out, but I am very sure that I was greatly supported and emboldened by the knowledge that if, at the last moment, my embarrassment should not allow me to begin my address, or if in the course of its delivery I should feel unable, for any reason, to go on with it, there was some one present who would read it for me. It had long been my habit to attend with my grandmother, bi-monthly, an early evening whist party at the house of an elderly neighbor. I had a bad headache on one of these appointed evenings, and Walkirk, who was a perfectly respectable and presentable man, went with my grandmother in my stead. I afterward heard that he played an excellent hand at whist, a remark which had never been made of me. But I will not refer at present to any further instances of the usefulness of my under-study, except to say that, as I found his feet were of the same size and shape as my own, I sent him to be measured for a pair of heavy walking-shoes which I needed; and I once arranged for him to serve in my place on a coroner's jury, in the case of a drowned infant. The evening listenings still went on, and as the scope of my remarks grew wider, and their purpose became better defined, it began to dawn upon me that it was selfish to devote these accounts of remarkable traveling experiences to the pleasure of only two men, myself and my listener; the public would be interested in these things. I ought to write a book. This idea pleased me very much. As Walkirk was now able to take my place in so many ways, I could give a good deal of time each day to composition; and, moreover, there was no reason why such work should interfere with my pleasure in being listened to. I could write by day, and talk at night. It would be all the better for my book that I should first orally deliver the matter to Walkirk, and afterward write it. I broached this idea to Walkirk; but, while he did not say so in words, it was plain to me he did not regard it with favor. He reflected a little before speaking. "The writing of a book," he said, "is a very serious thing; and although it is not my province to advise you, I will say that if I were in your place I should hesitate a good while before commencing a labor like that. I have no doubt, judging from what I have already heard of your travels, that you would make a most useful and enjoyable book, but the question in my mind is, whether the pleasure you would give your readers would repay you for the time and labor you would put upon this work."
