I said: "It gave a brilliant light in the King's Road, Brighton, and frightened a horse. The moment we got into the dark beyond Kemp Town it went out, and you were summoned for riding without a light. You may remember that on sunny afternoons you used to ride about with that lamp shining for all it was worth. When lighting-up time came it was naturally tired, and wanted a rest." "It was a bit irritating, that lamp," he murmured; "I remember it." I said: "It irritated me; it must have been worse for you. Then there are saddles," I went on--I wished to get this lesson home to him. "Can you think of any saddle ever advertised that you have _not_ tried?" He said: "It has been an idea of mine that the right saddle is to be found." I said: "You give up that idea; this is an imperfect world of joy and sorrow mingled. There may be a better land where bicycle saddles are made out of rainbow, stuffed with cloud; in this world the simplest thing is to get used to something hard. There was that saddle you bought in Birmingham; it was divided in the middle, and looked like a pair of kidneys." He said: "You mean that one constructed on anatomical principles." "Very likely," I replied. "The box you bought it in had a picture on the cover, representing a sitting skeleton--or rather that part of a skeleton which does sit." He said: "It was quite correct; it showed you the true position of the--" I said: "We will not go into details; the picture always seemed to me indelicate." He said: "Medically speaking, it was right." "Possibly," I said, "for a man who rode in nothing but his bones. I only know that I tried it myself, and that to a man who wore flesh it was agony. Every time you went over a stone or a rut it nipped you; it was like riding on an irritable lobster. You rode that for a month." "I thought it only right to give it a fair trial," he answered. I said: "You gave your family a fair trial also; if you will allow me the use of slang. Your wife told me that never in the whole course of your married life had she known you so bad tempered, so un-Christian like, as you were that month. Then you remember that other saddle, the one with the spring under it." He said: "You mean 'the Spiral.'" I said: "I mean the one that jerked you up and down like a Jack-in-the- box; sometimes you came down again in the right place, and sometimes you didn't. I am not referring to these matters merely to recall painful memories, but I want to impress you with the folly of trying experiments at your time of life." He said. "I wish you wouldn't harp so much on my age. A man at thirty- four--" "A man at what?" He said: "If you don't want the thing, don't have it. If your machine runs away with you down a mountain, and you and George get flung through a church roof, don't blame me."
