Since the days of Otto Lilienthal and his glider it has been the policy of Germany to keep track of all inventions likely to be embodied and made use of in the War Machine. It is a far cry from Lilienthal's glider to the last word in aërial construction such as the mysterious Zeppelin-Parseval sky monster that, carrying a complement of twenty-five men and twelve tons of explosives, sailed across the North Sea, circled over London, and returned to Germany. Lilienthal's glider kept aloft four minutes, but this new dread-naught of Germany's dying navy was aloft ninety-six hours, maintaining a speed of thirty-eight miles an hour, this even in the face of a storm pressure of almost eighty meters. Such feats as these are significant. They are at the same time the outcome and the cause for the development of this part of the War Machine. It is my purpose here to tell you how far Germany has advanced and progressed in this struggle for mastery of the sky. I shall disclose facts about her system that have never appeared in print--that have never been heard in conversation. They are known only to the General Staff at Berlin, not even in the cabinets of Europe. Germany without doubt has the most up-to-date aërial fleet in the world. The Budget of the Reichstag of 1908-1909 allows and provides for the building and maintenance of twelve dirigibles of Zeppelin type. As far as the knowledge of the rest of the world is concerned this is all the sky navy that Germany possesses. It is a fact, though, that she has three times the number which she officially acknowledges. The dirigible balloon centers in Germany are five and they are situated at vitally strategic points. There are two on the French border, one on the Russian border, one on the Atlantic Coast, and a central station near Berlin. The exact places are Strassburg, Frankfort-on-the-Main, Posen, Wilhelmshafen, and Berlin. This does not include the marvelous station at Helgoland in the North Sea, this being a strategic point in relation to Great Britain. Nothing is known about this Helgoland station. No one but those on official business are permitted within a thousand yards of it. I shall tell things concerning it. Besides these purely military posts, there are a number of commercial stations necessary as depots of the regular transportation aerial lines that operate for the convenience of the public. Like Germany's commercial steamers, however, they are controlled and subsidized by the Government. At a few hours' notice they can be converted and made use of for Government purposes. Taking these transportation lines into consideration, it is safe to state that by summer of the present year Germany could send fifty huge airships to war.
