I sat on the hill in a sort of despair. There was no town nearer than Chichester at which it was even remotely probable that there would be such a thing as an artist’s colourman. And yet, without white, my absurd little pictures would be as pointless as the world would be if there were no good people in it. I stared stupidly round, racking my brain for expedients. Then I suddenly stood up and roared with laughter, again and again, so that the cows stared at me and called a committee. Imagine a man in the Sahara regretting that he had no sand for his hour-glass. Imagine a gentleman in mid-ocean wishing that he had brought some salt water with him for his chemical experiments. I was sitting on an immense warehouse of white chalk. The landscape was made entirely out of white chalk. White chalk was piled more miles until it met the sky. I stooped and broke a piece off the rock I sat on; it did not mark so well as the shop chalks do; but it gave the effect. And I stood there in a trance of pleasure, realising that this Southern England is not only a grand peninsula, and a tradition and a civilisation; it is something even more admirable. It is a piece of chalk. III. The Secret of a Train All this talk of a railway mystery has sent my mind back to a loose memory. I will not merely say that this story is true: because, as you will soon see, it is all truth and no story. It has no explanation and no conclusion; it is, like most of the other things we encounter in life, a fragment of something else which would be intensely exciting if it were not too large to be seen. For the perplexity of life arises from there being too many interesting things in it for us to be interested properly in any of them; what we call its triviality is really the tag-ends of numberless tales; ordinary and unmeaning existence is like ten thousand thrilling detective stories mixed up with a spoon. My experience was a fragment of this nature, and it is, at any rate, not fictitious. Not only am I not making up the incidents (what there were of them), but I am not making up the atmosphere of the landscape, which were the whole horror of the thing. I remember them vividly, and they were as I shall now describe. .....
