It is futile to try to describe the haunting fear and horror which seized upon the majority of the millions who read these words. Business was paralyzed, for men found it impossible to concentrate their minds upon ordinary affairs. Every night the twin comets, still very bright, although they were fast retreating, brandished their fiery scimitars in the sky--more fearful to the imagination now, since Cosmo Versál had declared that it was the nebula that stimulated their energies. And by day the sky was watched with anxious eyes striving to detect signs of a deepening of the menacing hue, which, to an excited fancy, suggested a tinge of blood. Now, at last, Cosmo's warnings and entreaties bore practical fruit. Men began to inquire about places in his ark, and to make preparations for building arks of their own. He had not been interfered with after his memorable interview with the President of the United States, and had pushed his work at Mineola with redoubled energy, employing night gangs of workmen so that progress was continuous throughout the twenty-four hours. Standing on its platform, the ark, whose hull was approaching completion, rose a hundred feet into the air. It was 800 feet long and 250 broad--proportions which practical ship-builders ridiculed, but Cosmo, as original in this as in everything else, declared that, taking into account the buoyancy of levium, no other form would answer as well. He estimated that when its great engines were in place, its immense stores of material for producing power, its ballast, and its supplies of food stowed away, and its cargo of men and animals taken aboard, it would not draw more than twenty feet of water. Hardly a day passed now without somebody coming to Cosmo to inquire about the best method of constructing arks. He gave the required information, in all possible detail, with the utmost willingness. He drew plans and sketches, made all kinds of practical suggestions, and never failed to urge the utmost haste. He inspired every visitor at the same time with alarm and a resolution to go to work at once. Some did go to work. But their progress was slow, and as days passed, and the comets gradually faded out of sight, and then the dome of the sky showed a tendency to resume its natural blueness, the enthusiasm of Cosmo's imitators weakened, together with their confidence in his prophetic powers. They concluded to postpone their operations until the need of arks should become more evident. As to those who had sent inquiries about places in Cosmo's ark, now that the danger seemed to be blowing away, they did not even take the trouble to answer the very kind responses that he had made.
