_Sept. 10, '85._--The other evening Clara and I brought down our new soap bubble water and we all blew soap bubles. Papa blew his soap bubles and filled them with tobacco smoke and as the light shone on then they took very beautiful opaline colors. Papa would hold them and then let us catch them in our hand and they felt delightful to the touch the mixture of the smoke and water had a singularly pleasant effect. It is human life. We are blown upon the world; we float buoyantly upon the summer air a little while, complacently showing off our grace of form and our dainty iridescent colors; then we vanish with a little puff, leaving nothing behind but a memory--and sometimes not even that. I suppose that at those solemn times when we wake in the deeps of the night and reflect, there is not one of us who is not willing to confess that he is really only a soap-bubble, and as little worth the making. I remember those days of twenty-one years ago, and a certain pathos clings about them. Susy, with her manifold young charms and her iridescent mind, was as lovely a bubble as any we made that day--and as transitory. She passed, as they passed, in her youth and beauty, and nothing of her is left but a heartbreak and a memory. That long-vanished day came vividly back to me a few weeks ago when, for the first time in twenty-one years, I found myself again amusing a child with smoke-charged soap-bubbles. [Sidenote: (1885.)] Susy's next date is November 29th, 1885, the eve of my fiftieth birthday. It seems a good while ago. I must have been rather young for my age then, for I was trying to tame an old-fashioned bicycle nine feet high. It is to me almost unbelievable, at my present stage of life, that there have really been people willing to trust themselves upon a dizzy and unstable altitude like that, and that I was one of them. Twichell and I took lessons every day. He succeeded, and became a master of the art of riding that wild vehicle, but I had no gift in that direction and was never able to stay on mine long enough to get any satisfactory view of the planet. Every time I tried to steal a look at a pretty girl, or any other kind of scenery, that single moment of inattention gave the bicycle the chance it had been waiting for, and I went over the front of it and struck the ground on my head or my back before I had time to realise that something was happening. I didn't always go over the front way; I had other ways, and practised them all; but no matter which way was chosen for me there was always one monotonous result--the bicycle skinned my leg and leaped up into the air and came down on top of me. Sometimes its wires were so sprung by this violent performance that it had the collapsed look of an umbrella that had had a misunderstanding with a cyclone. After each day's practice I arrived at home with my skin hanging in ribbons, from my knees down. I plastered the ribbons on where
