The swaying view varied with these changes of altitude. Now they would be low and close, and he would distinguish in that steep, unusual perspective, windows, doors, street and sky signs, people and the minutest details, and watch the enigmatical behaviour of crowds and clusters upon the roofs and in the streets; then as they soared the details would shrink, the sides of streets draw together, the view widen, the people cease to be significant. At the highest the effect was that of a concave relief map; Bert saw the dark and crowded land everywhere intersected by shining waters, saw the Hudson River like a spear of silver, and Lower Island Sound like a shield. Even to Bert's unphilosophical mind the contrast of city below and fleet above pointed an opposition, the opposition of the adventurous American's tradition and character with German order and discipline. Below, the immense buildings, tremendous and fine as they were, seemed like the giant trees of a jungle fighting for life; their picturesque magnificence was as planless as the chances of crag and gorge, their casualty enhanced by the smoke and confusion of still unsubdued and spreading conflagrations. In the sky soared the German airships like beings in a different, entirely more orderly world, all oriented to the same angle of the horizon, uniform in build and appearance, moving accurately with one purpose as a pack of wolves will move, distributed with the most precise and effectual co-operation. It dawned upon Bert that hardly a third of the fleet was visible. The others had gone upon errands he could not imagine, beyond the compass of that great circle of earth and sky. He wondered, but there was no one to ask. As the day wore on, about a dozen reappeared in the east with their stores replenished from the flotilla and towing a number of drachenflieger. Towards afternoon the weather thickened, driving clouds appeared in the south-west and ran together and seemed to engender more clouds, and the wind came round into that quarter and blew stronger. Towards the evening the wind became a gale into which the now tossing airships had to beat. All that day the Prince was negotiating with Washington, while his detached scouts sought far and wide over the Eastern States looking for anything resembling an aeronautic park. A squadron of twenty airships detached overnight had dropped out of the air upon Niagara and was holding the town and power works. Meanwhile the insurrectionary movement in the giant city grew uncontrollable. In spite of five great fires already involving many acres, and spreading steadily, New York was still not satisfied that she was beaten.
