I have tried in vain to find the causes of these peculiar changes of feeling. The ostensible reasons, as given in the newspaper, are so trivial as to be hardly worthy of belief. For example, here is the kind of news that comes out from the City. "The news that a modus vivendi has been signed between the Sultan of Kowfat and the Shriek-ul-Islam has caused a sudden buoyancy in the City. Steel rails which had been depressed all morning reacted immediately while American mules rose up sharply to par."... "Monsieur Poincar, speaking at Bordeaux, said that henceforth France must seek to retain by all possible means the ping-pong championship of the world: values in the City collapsed at once."... "Despatches from Bombay say that the Shah of Persia yesterday handed a golden slipper to the Grand Vizier Feebli Pasha as a sign that he might go and chase himself: the news was at once followed by a drop in oil, and a rapid attempt to liquidate everything that is fluid..." But these mysteries of the City I do not pretend to explain. I have passed through the place dozens of times and never noticed anything particular in the way of depression or buoyancy, or falling oil, or rising rails. But no doubt it is there. A little beyond the city and further down the river the visitor finds this district of London terminating in the gloomy and forbidding Tower, the principal penitentiary of the city. Here Queen Victoria was imprisoned for many years. Excellent gasoline can be had at the American Garage immediately north of the Tower, where motor repairs of all kinds are also carried on. These, however, are but the superficial pictures of London, gathered by the eye of the tourist. A far deeper meaning is found in the examination of the great historic monuments of the city. The principal ones of these are the Tower of London (just mentioned), the British Museum and Westminster Abbey. No visitor to London should fail to see these. Indeed he ought to feel that his visit to England is wasted unless he has seen them. I speak strongly on the point because I feel strongly on it. To my mind there is something about the grim fascination of the historic Tower, the cloistered quiet of the Museum and the majesty of the ancient Abbey, which will make it the regret of my life that I didn't see any one of the three. I fully meant to: but I failed: and I can only hope that the circumstances of my failure may be helpful to other visitors. The Tower of London I most certainly intended to inspect. Each day, after the fashion of every tourist, I wrote for myself a little list of things to do and I always put the Tower of London on it. No doubt the reader knows the kind of little list that I mean. It runs: 1. Go to bank. 2. Buy a shirt. 3. National Picture Gallery. 4. Razor blades. 5. Tower of London. 6. Soap.
