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."

This was the first time that Walkirk had offered me advice. I had no idea of taking it, but I did not resent it.

"I do not look at the matter in that way," I said. "An absorbing labor will be good for me. My undertaking may result in overworking you, for you will be obliged to act as my under-study even more frequently than you do now."

"Oh, I'm not afraid of work," said he; "I can stand any amount of it. But how about the evening discourses,—will they come to an end?"

"Not at all," said I; "I shall go on giving you an account of my travels, just as before. This will help me to judge better what to put in and what to leave out."

"I am very glad to hear that," he said, with animation; "I do not hesitate to own to you that I should very greatly regret to lose those most interesting accounts of your experiences."
