I rejoice to say that Ambrose has received the D.S.O. for that achievement referred to in my last letter. He more than deserves it. He had a most terrible experience. The D.S.O. for a subaltern is one of the very highest honours that the Army has to bestow. We are all very bucked about it, especially the O.A. section of the battalion. How anomalous the War has become--the world's great Land Power striving to strike its decisive blow at sea, while the great Sea Power is endeavouring to strike its decisive blow on land! This double paradox will give much food for reflection to future historians. I am coming to the conclusion that without a complete knowledge of the facts it is well-nigh impossible to derive accurate deductions from History. It seems to me you can make History prove anything. To understand History in all its significance, one must be familiar also with literature, languages and science. Talking of science, do you see that some modern scientists are throwing doubt on the original theory of Evolution? They admit the possibility of the modification of species through natural selection, but they dispute the theory that any broad change takes place in the genera of organisms. They do not even admit the possibility of the atrophy, through long disuse, of organs of which the animal no longer has need. They are forced to admit that many species and genera have become extinct--so much is proved by the skeletons of prehistoric beasts found from time to time under the earth's surface. But what they dispute is that there is any connection between those beasts and living animals. They say, for instance, that as far back as we have records, we find the horse practically the same, organically speaking, as he is to-day. They cast doubt, that is, on the theory that the horse is descended from the pterodactyl.
