There were two Zeppelins in the shed we had entered--"L-68" and another monster of practically the same size. The former, with great irregularly shaped strips of fabric dangling all along its under side, suggested a gigantic shark in process of being ripped up the belly for skinning. Being deflated, the weight of its frame was supported by a number of heavy wooden props evenly distributed along either side from end to end. Its mate, on the other hand, being full of hydrogen and practically ready for flight, had to be prevented from rising and bumping against the yellow skylights by a series of light cables, the upper ends of which were attached at regular intervals along both sides of the framework, while below they were made fast to heavy steel shoes which ran in grooves set in the concrete floor. The latter contrivance--especially an arrangement for the instant slipping of the cable--was very cleverly devised and greatly interested the Allied experts. There were two or three things the popular mind had credited the modern Zeppelin with embodying which we did not find in these latest examples of German airship development. One of these was an "anti-bomb protector" on the top, something after the style of the steel nets erected over London banks and theatres for the purpose of detonating dropped explosives before they penetrated the roof. The fact that attempts to destroy Zeppelins by bomb had invariably--with the exception of the one brought down by Warneford in Belgium in 1915--resulted in failure, was doubtless largely responsible for this belief in the existence of a protecting net, whereas the reason for those failures is probably to be found in the fact that only about one bomb in a hundred will find enough resistance in striking an airship to detonate. At any rate, there were no indications that either the earlier or later Zeppelins we saw had ever been protected in this way. Indeed, we did not even see a single one of the machine-guns, which every one had taken for granted were mounted on top of all Zeppelins to resist aeroplane attack, though these, of course, with their platforms, may well have been removed in the course of the disarmament imposed by the armistice terms. Nor had these late airships the bright golden colour of those that one saw over London in the earlier raids. That the refulgent tawniness of them was not due entirely to the reflected beams of the searchlights was proved by the uncharred fragments of fabric one had picked up at Cuffley and Potters' Bar. But the German designers had been giving a good deal of study to invisibility, since that time, with the result that these new airships were coloured over all their exposed surfaces a dull slaty black that would hardly reflect a beam of bright sunshine.
