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.
It is a singular circumstance that not one of these anxious inquirers seemed to have paid particular attention to a very significant sentence in his reply. If they had given it a little thought, it would probably have set them pondering, although they might have been more puzzled than edified. The sentence ran as follows:
"While assuring you that my ark has been built for the benefit of my fellow men, I am bound to tell you that I reserve absolutely the right to determine who are truly representative of _homo sapiens_."
The fact was that Cosmo had been turning over in his mind the great fundamental question which he had asked himself when the idea of trying to save the human race from annihilation had first occurred to him, and apparently he had fixed upon certain principles that were to guide him.
