Abruptly something dropped from the zenith; something like a barrel or a huge football.

CRASH! It smashed with an immense report. It had fallen among the grounded Asiatic aeroplanes that lay among the turf and flower-beds near the river. They flew in scraps and fragments, turf, trees, and gravel leapt and fell; the aeronauts still lying along the canal bank were thrown about like sacks, catspaws flew across the foaming water. All the windows of the hotel hospital that had been shiningly reflecting blue sky and airships the moment before became vast black stars. Bang!—a second followed. Bert looked up and was filled with a sense of a number of monstrous bodies swooping down, coming down on the whole affair like a flight of bellying blankets, like a string of vast dish-covers. The central tangle of the battle above was circling down as if to come into touch with the power-house fight. He got a new effect of airships altogether, as vast things coming down upon him, growing swiftly larger and larger and more overwhelming, until the houses over the way seemed small, the American rapids narrow, the bridge flimsy, the combatants infinitesimal. As they came down they became audible as a complex of shootings and vast creakings and groanings and beatings and throbbings and shouts and shots. The fore-shortened black eagles at the fore-ends of the Germans had an effect of actual combat of flying feathers.

Some of these fighting airships came within five hundred feet of the ground. Bert could see men on the lower galleries of the Germans, firing rifles; could see Asiatics clinging to the ropes; saw one man in aluminium diver's gear fall flashing headlong into the waters above Goat Island. For the first time he saw the Asiatic airships closely. From this aspect they reminded him more than anything else of colossal snowshoes; they had a curious patterning in black and white, in forms that reminded him of the engine-turned cover of a watch. They had no hanging galleries, but from little openings on the middle line peeped out men and the muzzles of guns. So, driving in long, descending and ascending curves, these monsters wrestled and fought. It was like clouds fighting, like puddings trying to assassinate each other. They whirled and circled about each other, and for a time threw Goat Island and Niagara into a smoky twilight, through which the sunlight smote in shafts and beams. They spread and closed and spread and grappled and drove round over the rapids, and two miles away or more into Canada, and back over the Falls again. A German caught fire, and the whole crowd broke away from her flare and rose about her dispersing, leaving her to drop towards Canada and blow up as she dropped. Then with renewed uproar the others closed again. Once from the men in Niagara city came a sound like an ant-hill cheering. Another German burnt, and one badly deflated by the prow of an antagonist, flopped out of action southward.

It became more and more evident that the Germans were getting the worst of the unequal fight. More and more obviously were they being persecuted. Less and less did they seem to fight with any object other than escape. The Asiatics swept by them and above them, ripped their bladders, set them alight, picked off their dimly seen men in diving clothes, who struggled against fire and tear with fire extinguishers and silk ribbons in the inner netting. They answered only with ineffectual shots. Thence the battle circled back over Niagara, and then suddenly the Germans, as if at a preconcerted signal, broke and dispersed, going east, west, north, and south, in open and confused flight. The Asiatics, as they realised this, rose to fly above them and after them. Only one little knot of four Germans and perhaps a dozen Asiatics remained fighting about the Hohenzollern and the Prince as he circled in a last attempt to save Niagara.

Round they swooped once again over the Canadian Fall, over the waste of waters eastward, until they were distant and small, and then round and back, hurrying, bounding, swooping towards the one gaping spectator.

The whole struggling mass approached very swiftly, growing rapidly larger, and coming out black and featureless against the afternoon sun and above the blinding welter of the Upper Rapids. It grew like a storm cloud until once more it darkened the sky. The flat Asiatic airships kept high above the Germans and behind them, and fired unanswered bullets into their gas-chambers and upon their flanks—the one-man flying-machines hovered and alighted like a swarm of attacking bees. Nearer they came, and nearer, filling the lower heaven. Two of the Germans swooped and rose again, but the Hohenzollern had suffered too much for that. She lifted weakly, turned sharply as if to get out of the battle, burst into flames fore and aft, swept down to the water, splashed into it obliquely, and rolled over and over and came down stream rolling and smashing and writhing like a thing alive, halting and then coming on again, with her torn and bent propeller still beating the air. The bursting flames spluttered out again in clouds of steam. It was a disaster gigantic in its dimensions. She lay across the rapids like an island, like tall cliffs, tall cliffs that came rolling, smoking, and crumpling, and collapsing, advancing with a sort of fluctuating rapidity upon Bert. One Asiatic airship—it looked to Bert from below like three hundred yards of pavement—whirled back and circled two or three times over that great overthrow, and half a dozen crimson flying-machines danced for a moment like great midges in the sunlight before they swept on after their fellows. The rest of the fight had already gone over the island, a wild crescendo of shots and yells and smashing uproar. It was hidden from Bert now by the trees of the island, and forgotten by him in the nearer spectacle of the huge advance of the defeated German airship. Something fell with a mighty smashing and splintering of boughs unheeded behind him.

It seemed for a time that the Hohenzollern must needs break her back upon the Parting of the Waters, and then for a time her propeller flopped and frothed in the river and thrust the mass of buckling, crumpled wreckage towards the American shore. Then the sweep of the torrent that foamed down to the American Fall caught her, and in another minute the immense mass of deflating wreckage, with flames spurting out in three new places, had crashed against the bridge that joined Goat Island and Niagara city, and forced a long arm, as it were, in a heaving tangle under the central span. Then the middle chambers blew up with a loud report, and in another moment the bridge had given way and the main bulk of the airship, like some grotesque cripple in rags, staggered, flapping and waving flambeaux to the crest of the Fall and hesitated there and vanished in a desperate suicidal leap.

Its detached fore-end remained jammed against that little island, Green Island it used to be called, which forms the stepping-stone between the mainland and Goat Island's patch of trees.

Bert followed this disaster from the Parting of the Waters to the bridge head. Then, regardless of cover, regardless of the Asiatic airship hovering like a huge house roof without walls above the Suspension Bridge, he sprinted along towards the north and came out for the first time upon that rocky point by Luna Island that looks sheer down upon the American Fall. There he stood breathless amidst that eternal rush of sound, breathless and staring.

Far below, and travelling rapidly down the gorge, whirled something like a huge empty sack. For him it meant—what did it not mean?—the German air-fleet, Kurt, the Prince, Europe, all things stable and familiar, the forces that had brought him, the forces that had seemed indisputably victorious. And it went down the rapids like an empty sack and left the visible world to Asia, to yellow people beyond Christendom, to all that was terrible and strange!
