Seaton, with his mind in a whirl, walked slowly to his desk, picked up his blackened and battered briar pipe, and sat down to study out what he had done, or what could possibly have happened, to result in such an unbelievable infraction of all the laws of mechanics and gravitation. He knew that he was sober and sane, that the thing had actually happened. But why? And how? All his scientific training told him that it was impossible. It was unthinkable that an inert mass of metal should fly off into space without any applied force. Since it had actually happened, there must have been applied an enormous and hitherto unknown force. What was that force? The reason for this unbelievable manifestation of energy was certainly somewhere in the solution, the electrolytic cell, or the steam-bath. Concentrating all the power of his highly-trained analytical mind upon the problem--deaf and blind to everything else, as was his wont when deeply interested--he sat motionless, with his forgotten pipe clenched between his teeth. Hour after hour he sat there, while most of his fellow-chemists finished the day's work and left the building and the room slowly darkened with the coming of night. Finally he jumped up. Crashing his hand down upon the desk, he exclaimed: "I have liberated the intra-atomic energy of copper! Copper, 'X,' and electric current! "I'm sure a fool for luck!" he continued as a new thought struck him. "Suppose it had been liberated all at once? Probably blown the whole world off its hinges. But it wasn't: it was given off slowly and in a straight line. Wonder why? Talk about power! Infinite! Believe me, I'll show this whole Bureau of Chemistry something to make their eyes stick out, tomorrow. If they won't let me go ahead and develop it, I'll resign, hunt up some more 'X', and do it myself. That bath is on its way to the moon right now, and there's no reason why I can't follow it. Martin's such a fanatic on exploration, he'll fall all over himself to build us any kind of a craft we'll need ... we'll explore the whole solar system! Great Cat, what a chance! A fool for luck is right!" He came to himself with a start. He switched on the lights and saw that it was ten o'clock. Simultaneously he recalled that he was to have had dinner with his fiancee at her home, their first dinner since their engagement. Cursing himself for an idiot he hastily left the building, and soon his motorcycle was tearing up Connecticut Avenue toward his sweetheart's home. CHAPTER II Steel Becomes Interested
