It fell as one piece, that great building. It didn't topple until it had almost reached the river and its shrieking plunge became meteor-like, the sound of its fall monstrous beyond imagining. The conference above the Hadley building fancied they could feel the outward rush of air displaced by the falling monster--and drew back in fear from the edge of the roof. The Vandercook struck the surface of the Hudson and an uprush of geysering water for a few seconds blotted the great building from view. Then all Manhattan seemed to shudder. Most of it was perhaps fancy, but thousands of frightened Manhattanites saw that fall, heard the whistling, and felt the trembling of immovable Manhattan. The great columns of water fell back into the turbulent Hudson which had received the plunging building. Not so much as a wooden desk showed above the surface as far as any one could see from shore. Not a soul had been saved. Shrieks of the doomed had never stopped from the moment the Vandercook building had started its mad journey aloft. Jeter whirled on Hadley. "Will you see that all my suggestions are carried out, Hadley?" he demanded. Hadley, face gray as ashes, nodded. From Manhattan rose the long abysmal wailing of a populace just finding its voice of fear after a stunning, numbing catastrophe. "I'll do whatever you say, Jeter," said Hadley. "We all agreed before the arrival of Eyer and yourself that your advice would be followed if you chose to give any." "Then listen," said Jeter, while Eyer stood quietly at his elbow, missing nothing. "Advise the people of New York to quit the city as quietly and in as orderly a manner as possible. Let the police commissioner look after that. Then get word to the leading aviation authorities, promoters, and fliers and have them get to our Mineola laboratory as fast as possible. We've kept much of the detail of construction of our space-ship secret, for obvious reasons. But the time has come to forget personal aggrandizement and the world must know all we have learned by our labor and research. Then see that every manufacturing agency, capable of even a little of what it will take for the program, is drafted to the work--by Federal statute if necessary--and turn out copies of our plane as quickly as God will let you." * * * * * Hadley's eyes were bulging. So were those of the others who had crowded close to listen. They seemed to think Jeter had taken leave of his senses, and yet--all had seen the Vandercook building perform the utterly impossible. Hadley nodded. "What do you want with the filers and others at your laboratory?"
