Bertie Swanborough and Stark Munro will be blowing about on the west wind, and dirtying the panes of careful housewives long before the half of it has come to pass. And then man himself will change, of course. The teeth are going rapidly. You’ve only to count the dentists’ brass plates in Birchespool to be sure of that. And the hair also. And the sight. Instinctively, when we think of the more advanced type of young man, we picture him as bald, and with double eye-glasses. I am an absolute animal myself, and my only sign of advance is that two of my back teeth are going. On the other hand, there is some evidence in favour of the development of a sixth sense-that of perception. If I had it now I should know that you are heartily weary of all my generalisations and dogmatism. And certainly there must be a spice of dogmatism in it when we begin laying down laws about the future; for how do we know that there are not phases of nature coming upon us of which we have formed no conception? After all, a few seconds are a longer fraction of a day than an average life is of the period during which we know that the world has been in existence. But if a man lived only for a few seconds of daylight, his son the same, and his son the same, what would their united experiences after a hundred generations tell them of the phenomenon which we call night? So all our history and knowledge is no guarantee that our earth is not destined for experiences of which we can form no conception. But to drop down from the universe to my own gnat’s buzz of an existence, I think I have told you everything that might interest you of the first six months of my venture. Towards the end of that time my little brother Paul came down--and the best of companions he is! He shares the discomforts of my little menage in the cheeriest spirit, takes me out of my blacker humours, goes long walks with me, is interested in all that interests me (I always talk to him exactly as if he were of my own age), and is quite ready to turn his hand to anything, from boot-blacking to medicine-carrying. His one dissipation is cutting out of paper, or buying in lead (on the rare occasion when we find a surplus), an army of little soldiers. I have brought a patient into the consulting room, and found a torrent of cavalry, infantry, and artillery pouring across the table. I have been myself attacked as I sat silently writing, and have looked up to find fringes of sharp-shooters pushing up towards me, columns of infantry in reserve, a troop of cavalry on my flank, while a battery of pea muzzle-loaders on the ridge of my medical dictionary has raked my whole position--with the round, smiling face of the general behind it all. I don’t know how many regiments he has on a peace footing; but if serious trouble were to break out, I am convinced that every sheet of paper in the house would spring to arms.
