Mr. Dodgson's views on Sunday Observance were old-fashioned, but he lived up to them, and did not try to force them upon people with whose actions he had no concern. They were purely matters of "private opinion" with him. On October 2nd he wrote to Miss E.G. Thomson, who was illustrating his "Three Sunsets":—
Would you kindly do no sketches, or photos, for me, on a Sunday? It is, in my view (of course I don't condemn any one who differs from me) inconsistent with keeping the day holy. I do not hold it to be the Jewish "Sabbath," but I do hold it to be "the Lord's Day," and so to be made very distinct from the other days.
In December, the Logical controversy being over for a time, Mr. Dodgson invented a new problem to puzzle his mathematical friends with, which was called "The Monkey and Weight Problem." A rope is supposed to be hung over a wheel fixed to the roof of a building; at one end of the rope a weight is fixed, which exactly counterbalances a monkey which is hanging on to the other end. Suppose that the monkey begins to climb the rope, what will be the result? The following extract from the Diary illustrates the several possible answers which may be given:—
Got Professor Clifton's answer to the "Monkey and Weight Problem." It is very curious, the different views taken by good mathematicians. Price says the weight goes up, with increasing velocity; Clifton (and Harcourt) that it goes up, at the same rate as the monkey; while Sampson says that it goes down.
On December 24th Mr. Dodgson received the first twelve copies of "Sylvie and Bruno Concluded," just about four years after the appearance of the first part of the story. In this second volume the two fairy children are as delightful as ever; it also contains what I think most people will agree to be the most beautiful poem Lewis Carroll ever wrote, "Say, what is the spell, when her fledglings are cheeping?" (p. 305). In the preface he pays a well-deserved compliment to Mr. Harry Furniss for his wonderfully clever pictures; he also explains how the book was written, showing that many of the amusing remarks of Bruno had been uttered by real children. He makes allusion to two books, which only his death prevented him from finishing—"Original Games and Puzzles," and a paper on "Sport," viewed from the standpoint of the humanitarian. From a literary point of view the second volume of "Sylvie and Bruno" lacks unity; a fairy tale is all very well, and a novel also is all very well, but the combination of the two is surely a mistake. However, the reader who cares more for the spirit than the letter will not notice this blemish; to him "Sylvie and Bruno Concluded" will be interesting and helpful, as the revelation of a very beautiful personality.
You have made everything turn out just as I should have chosen [writes a friend to whom he had sent a copy], and made right all that disappointed me in the first part. I have not only to thank you for writing an interesting book, but for writing a helpful one too. I am sure that "Sylvie and Bruno" has given me many thoughts that will help me all life through. One cannot know "Sylvie" without being the better for it. You may say that "Mister Sir" is not consciously meant to be yourself, but I cannot help feeling that he is. As "Mister Sir" talks, I hear your voice in every word. I think, perhaps, that is why I like the book so much.
I have received an interesting letter from Mr. Furniss, bearing upon the subject of "Sylvie and Bruno," and Lewis Carroll's methods of work. The letter runs as follows:—
I have illustrated stories of most of our leading authors, and I can safely say that Lewis Carroll was the only one who cared to understand the illustrations to his own book. He was the W. S. Gilbert for children, and, like Gilbert producing one of his operas, Lewis Carroll took infinite pains to study every detail in producing his extraordinary and delightful books. Mr. Gilbert, as every one knows, has a model of the stage; he puts up the scenery, draws every figure, moves them about just as he wishes the real actors to move about. Lewis Carroll was precisely the same. This, of course, led to a great deal of work and trouble, and made the illustrating of his books more a matter of artistic interest than of professional profit. I was seven years illustrating his last work, and during that time I had the pleasure of many an interesting meeting with the fascinating author, and I was quite repaid for the trouble I took, not only by his generous appreciation of my efforts, but by the liberal remuneration he gave for the work, and also by the charm of having intercourse with the interesting, if somewhat erratic genius.
A book very different in character from "Sylvie and Bruno," but under the same well-known pseudonym, appeared about the same time. I refer to "Pillow Problems," the second part of the series entitled "Curiosa Mathematica."
"Pillow Problems thought out during wakeful hours" is a collection of mathematical problems, which Mr. Dodgson solved while lying awake at night. A few there are to which the title is not strictly applicable, but all alike were worked out mentally before any diagram or word of the solution was committed to paper.
