This series of papers is the fourth of its kind which I have offered to my readers. I may be allowed to look back upon the succession of serial articles which was commenced more than thirty years ago, in 1857. "The Autocrat of the Breakfast-Table" was the first of the series. It was begun without the least idea what was to be its course and its outcome. Its characters shaped themselves gradually as the manuscript grew under my hand. I jotted down on the sheet of blotting paper before me the thoughts and fancies which came into my head. A very odd-looking object was this page of memoranda. Many of the hints were worked up into formal shape, many were rejected.

Sometimes I recorded a story, a jest, or a pun for consideration, and made use of it or let it alone as my second thought decided. I remember a curious coincidence, which, if I have ever told in print, --I am not sure whether I have or not,--I will tell over again. I mention it, not for the pun, which I rejected as not very edifying and perhaps not new, though I did not recollect having seen it.

Mulier, Latin for woman; why apply that name to one of the gentle but occasionally obstinate sex? The answer was that a woman is (sometimes) more mulish than a mule. Please observe that I did not like the poor pun very well, and thought it rather rude and inelegant. So I left it on the blotter, where it was standing when one of the next numbers of "Punch" came out and contained that very same pun, which must have been hit upon by some English contributor at just about the same time I fell upon it on this side of the Atlantic. This fact may be added to the chapter of coincidences which belongs to the first number of this series of papers.

The "Autocrat" had the attraction of novelty, which of course was wanting in the succeeding papers of similar character. The criticisms upon the successive numbers as they came out were various, but generally encouraging. Some were more than encouraging; very high-colored in their phrases of commendation. When the papers were brought together in a volume their success was beyond my expectations. Up to the present time the "Autocrat" has maintained its position. An immortality of a whole generation is more than most writers are entitled to expect. I venture to think, from the letters I receive from the children and grandchildren of my first set of readers, that for some little time longer, at least, it will continue to be read, and even to be a favorite with some of its readers. Non omnis moriar is a pleasant thought to one who has loved his poor little planet, and will, I trust, retain kindly recollections of it through whatever wilderness of worlds he may be called to wander in his future pilgrimages. I say "poor little planet." Ever since I had a ten cent look at the transit of Venus, a few years ago, through the telescope in the Mall, the earth has been wholly different to me from what it used to be. I knew from books what a speck it is in the universe, but nothing ever brought the fact home like the sight of the sister planet sailing across the sun's disk, about large enough for a buckshot, not large enough for a full-sized bullet. Yes, I love the little globule where I have spent more than fourscore years, and I like to think that some of my thoughts and some of my emotions may live themselves over again when I am sleeping. I cannot thank all the kind readers of the "Autocrat" who are constantly sending me their acknowledgments. If they see this printed page, let them be assured that a writer is always rendered happier by being told that he has made a fellow-being wiser or better, or even contributed to his harmless entertainment. This a correspondent may take for granted, even if his letter of grateful recognition receives no reply. It becomes more and more difficult for me to keep up with my correspondents, and I must soon give it up as impossible.
