I have already told you that for many years past Germany has been very envious of the British Empire. A great German historian was never tired of teaching that Britain was _the_ enemy of Germany. She was, he said, a "robber state;" she had become mistress of one-fifth of the whole world by making cat's paws of other races; and she had no real right to all this territory. She could not even rule it properly. If ever she had been strong and warlike, that time had long gone by. Though she appeared to be strong, she was really very weak, and quite unable to hold her Empire against such a strong Power as Germany. The Germans have come to believe this teaching, and for years past they have looked forward to "the day" on which they would challenge the power of Great Britain, and, after having defeated her, would enter into her heritage. They have also been taught that there is nothing wrong in trying to seize the territory of other nations. Might, they believe, is right, and the spoils of the world are for the strongest. Newspaper writers in Germany have constantly preached this doctrine to the people, and several Prussian officers have written books showing how Germany ought to go to work to beat down Great Britain, and tear her Empire from her. War has become the religion of Germany, and she has prepared for it with wonderful foresight and zeal. While she has grown to be a great manufacturing and trading nation, she has never for a moment neglected her Army nor ceased to build up her Navy. She has also tried to win the mastery of the air. When Count Zeppelin, about the year 1899, invented a great airship which could travel for hundreds of miles and carry some thirty or forty men, the Kaiser saw at once that it might become a great weapon of war. Germany now possesses about thirty of these airships, and they are meant to play a large part in an invasion of Britain. On the opposite page you will see a picture of a modern Zeppelin, with a part of the covering removed to show you the framing of the interior, and the many separate gas chambers which it contains. It is said that even if half these chambers were destroyed the airship would still float and answer its helm. The outside covering is made of light metal known as aluminium. It costs some thousands of pounds to inflate a Zeppelin, and two hundred pounds a week to restore the gas lost by evaporation. The _Victoria Luise_, one of the crack Zeppelins, has made some wonderful trips, and she could no doubt fly from Kiel or Hamburg over any part of the British Isles and back again. But fog and storm are her deadly enemies, and there are many other difficulties to be overcome before she could make a raid upon Britain, drop bombs on her cities, and return in safety.
