At the largest point the framework had a diameter of 72 feet, and was of streamlike form, the bow being sensibly blunter than the stern, which, indeed, tapered off to a sharp point. The length of the vessel appeared to have been 650 feet or 680 feet, and the weight complete, with engines, fuel, guns, and ammunition, was calculated at 50 tons. The hydrogen capacity was 2,000,000 cubic feet, and there were 24 ballonets extending the whole length of the ship. Of the envelope only one or two fragments were to be seen, the rest having been burnt. The airship, which was numbered L33, was of quite recent construction, having been built last July, and its cost is estimated by the Admiralty authorities at about a quarter of a million. How long was required for building it could not be told from an inspection of the remains, but the enormous amount of detail was evident enough. To enable the crew, which consisted of twenty-two men, to move from one part of the ship to another, a cat-walk ran along the keel, enclosed in an arched passage. It consisted of a narrow footway, nine inches in width and made of wood—one of the very few examples of wood construction used—and provision for ventilation was made in the shape of shafts rising to the top of the ship. In all there were four gondolas—one forward, two amidships, and one aft. The first of these constituted the navigating bridge. It was divided into three parts. The first was set apart for the commander, and in it were concentrated the controls of the horizontal and vertical rudders at the stern, the engine-room, telegraphs, and the switches for the electrical release of the bombs. These last, of which sixty were carried, were actually arranged amidships, and the sliding door which was opened to allow them to fall could still be seen moving freely on its bearings.
