And then the speck vanished. Danny followed it with the powerful glasses of his sighting tube; he saw it swing inland--saw it move like a line of silvery light, almost, swifter in its motion than his instrument could follow. But even in that swift flight Danny's eyes observed one fact: the enemy ship was coming down; it slanted in on that long volplane that must have ripped the air apart like a bolt of lightning. And Danny's red rocket swept out and around in a long, looping flight, while he laid the ship on the course that other had followed. "That's one of them," he said savagely; "there must be two more. But I'll get this one if I have to crash him in air and smash my own ship right through him." * * * * * The mind of Danny O'Rourke was filled with only one idea; he had sighted his prey--the ship in which sat a man-thing who had sent a terrible death to Danny's fellows. And, though his hands moved carefully and methodically, though externally he was cool and collected, within him was a seething maelstrom of hate. All he saw was that giant figure as he had seen it before; all he knew was that he must overtake that speeding ship and send it to earth. He had even forgotten Morgan; perhaps he was never fully conscious of his coming from the moment when that other trembling, shaken man had shouted: "New York! New York's gone!" "There aren't two more," the Infant was saying from his seat at the rear of the cabin: "there's just one. Those three lines were always parallel except when they widened out: that meant that he had gone up higher. If we ever see that ship, we'll see three discharge tubes for the ray." Danny O'Rourke turned his eyes that had gone haggard and deep-sunk with the sights they had seen. He stared vacantly at the Infant. "Didn't know," he said thickly, "--didn't know you were here. I'll set you down; I'll let you out before I ram him...." For reply, the other pointed ahead. The red ship had torn through a layer of thick clouds; Danny was flying below them above a mountainous world of bare hill-tops and wooded valleys. Directly ahead, hovering high over a mountain higher than its fellows, was the white craft of the enemy; Danny, saw it in hard outline against the darker masses of clouds beyond. He saw that it was motionless, that a slender cable was suspended for a thousand feet below, and that the end of the cable, hanging close above the mountain top, was split into a score of wires that stood out in all directions, while, from each, poured a stream of blue fire. And once more all this that he saw was as nothing to the pilot; all thought, too, of his fellow victim went from his mind. He could see only the white ship, doubly hideous because of its seeming purity; and, as before, he brought the cross hairs of directional sights upon it while he opened the rocket exhaust to the full.
