Cause and effect are to be found everywhere. Rents went up in Shepherd’s Bush. It was painful and shocking that rents should go up in Shepherd’s Bush. But to a certain point we are all scientific students of cause and effect, and there was not a clerk lunching at a Lyons Restaurant who did not scientifically put two and two together and see in the (once) Two-penny Tube the cause of an excessive demand for wigwams in Shepherd’s Bush, and in the excessive demand for wigwams the cause of the increase in the price of wigwams.

“Simple!” you say, disdainfully. Everything – the whole complex movement of the universe – is as simple as that – when you can sufficiently put two and two together. And, my dear sir, perhaps you happen to be an estate agent’s clerk, and you hate the arts, and you want to foster your immortal soul, and you can’t be interested in your business because it’s so humdrum.

Nothing is humdrum.

The tremendous, changeful picturesqueness of life is marvellously shown in an estate agent’s office. What! There was a block of traffic in Oxford Street; to avoid the block people actually began to travel under the cellars and drains, and the result was a rise of rents in Shepherd’s Bush! And you say that isn’t picturesque! Suppose you were to study, in this spirit, the property question in London for an hour and a half every other evening. Would it not give zest to your business, and transform your whole life?
