Helgoland has always been a sore spot of British diplomacy. Originally England owned the island; now it is a menace to England. When Lord Salisbury was Prime Minister of England, he conceived what he believed to be a shrewd diplomatic move. He offered Bismarck the island of Helgoland in exchange for some East African concessions. Helgoland is now the key and guard of Germany's main artery of commerce, being the key to Hamburg. With the dirigible station of Helgoland to guard her, Hamburg is impregnable and on England's northern coast they have a way of looking out across the North Sea with troubled eyes, for who knows when those terrible cartridge-shaped monsters will rise into the air and sweep over the sea? Stranger things have happened, even though the countries have their secret diplomatic understandings. Let us consider one of these new war monsters, the latest and most powerful, the X 15. The lateat Zeppelins, charged with the newly discovered dioxygenous gas, giving these sky battleships triple lifting capacity; the perfecting of the Diesel motor, giving enormous consumption (fifty of these Diesel engines, their workings secret to the German Government, are stored under guard at the big navy yards at Wilhelmshafen and Kiel, ready to be installed at the break of war into submarines and dirigibles), have given the German type of aircraft an importance undreamed of and unsuspected by the rest of the world. The operating sphere of the new balloons has extended from 100 to 1,200-1,400 kilometers. Secret trial trips of a fully equipped Zeppelin like X 15, carrying a crew of twenty-four men, six quick-firing guns, seven tons of explosive, have extended from Stettin, over the Baltic, over Swedenburg in Sweden, recrossing the Baltic and landing at Swinemunde, with enough gas, fuel, and provisions left to keep aloft another thirty-six hours. The distance all told covered on one of these trips was 1,180 kilometers. This fact speaks for itself. The return distance from Helgoland to London, or any midland towns in England, corresponds with the mileage covered on recent trips. In the event of hostilities between England and Germany, this statement needs no explanation. That is why I mentioned that the latter-day Zeppelins were a powerful factor in bringing about an amiable understanding between those two powerful countries. For neither the historic wooden walls of Nelson's day nor the steel plates of her modern navy could help England or any other nation against the inroads of the monsters of the air. The capacity of seven tons of explosive does not exhaust the resources of this type of weapon. I have it on good authority that the new Zeppelins can carry double that quantity of explosive if necessary. As the size of these vessels increases, so does the ratio of their carrying capacity.
