He was now enjoying a respite from these attentions, but he felt it was at best an interlude, and he was doing what he could to appreciate his position. Incidentally he was having some hot coffee and pie in an untidy inadvertent manner, with an eye fluttering nervously over the side of the car. At first he had ascribed the growing interest in his career to his ill-conceived attempt to land in the bright little upland town, but now he was beginning to realise that the military rather than the civil arm was concerned about him. He was quite involuntarily playing that weird mysterious part--the part of an International Spy. He was seeing secret things. He had, in fact, crossed the designs of no less a power than the German Empire, he had blundered into the hot focus of Welt-Politik, he was drifting helplessly towards the great Imperial secret, the immense aeronautic park that had been established at a headlong pace in Franconia to develop silently, swiftly, and on an immense scale the great discoveries of Hunstedt and Stossel, and so to give Germany before all other nations a fleet of airships, the air power and the Empire of the world. Later, just before they shot him down altogether, Bert saw that great area of passionate work, warm lit in the evening light, a great area of upland on which the airships lay like a herd of grazing monsters at their feed. It was a vast busy space stretching away northward as far as he could see, methodically cut up into numbered sheds, gasometers, squad encampments, storage areas, interlaced with the omnipresent mono-rail lines, and altogether free from overhead wires or cables. Everywhere was the white, black and yellow of Imperial Germany, everywhere the black eagles spread their wings. Even without these indications, the large vigorous neatness of everything would have marked it German. Vast multitudes of men went to and fro, many in white and drab fatigue uniforms busy about the balloons, others drilling in sensible drab. Here and there a full uniform glittered. The airships chiefly engaged his attention, and he knew at once it was three of these he had seen on the previous night, taking advantage of the cloud welkin to manoeuvre unobserved. They were altogether fish-like. For the great airships with which Germany attacked New York in her last gigantic effort for world supremacy--before humanity realized that world supremacy was a dream--were the lineal descendants of the Zeppelin airship that flew over Lake Constance in 1906, and of the Lebaudy navigables that made their memorable excursions over Paris in 1907 and 1908.
