"We thought it best to take the night train, my son," said Richard, starting up at Oliver's caressing touch--he had put both hands on his father's shoulders. "You got your dear mother's letter of course. Oh, I'm so glad to see you! Sit down here alongside of us. How well you are looking, my son," and he patted him lovingly on the arm. "What a whirl it all is! Nathan and I have been here for hours; we arrived at six o'clock. Did you ever see anything like it? The people never seem to stop coming. Ah! this is the place for you, my boy. Everything is so alive, so full of purpose, so intense, so delightful and inspiring to me. And such a change in the years since I was here." He had brought the motor with him. It lay at the moment in a square box inside the office-railing. Not the big one which he had just perfected--that one was at home under the window in the old shop, in the back yard in Kennedy Square--but a smaller working model made of pine wood, with glass-tumblers for jars and imitation magnets wrapped round with thread instead of wire--the whole unintelligible to the layman, but perfectly clear to the scientist. He had with him, too, packed in a small carpet-bag, which lay within reach of his hand, all the patents which had been granted him as the work progressed--besides a huge bundle of papers, such as legal documents, notices from the scientific journals, and other data connected with the great Horn Galvanic Motor, which was soon to revolutionize the motive power of the world. Tucked away in his inside pocket, ready for instant use, was Amos Cobb's letter, introducing "the distinguished inventor, Mr. Richard Horn, of Kennedy Square," etc., etc., to the group of capitalists who were impatiently waiting his arrival, and who were to furnish the unlimited sums of money necessary in its development--unlimited sums being ready for any scheme, no matter how chimerical, in the flush times through which the country was then passing. "I have succeeded at last, my boy, as I wrote you," continued Richard, with glowing eyes. "Even that small motor at home--the one you know--that one has a lifting power of a hundred pounds. All that is necessary now is to increase the size of the batteries and the final result is assured. Let me show you this"--and, oblivious of the many eyes fastened on him, he drew toward him the black carpet-bag and took out a sheet of paper covered with red and blue lines. "You see where the differences are. And you see here"--and he pointed out the details with his thin white finger--"what I have done since I explained to you the new additions. This drawing, when carried out, will result in a motor with a lifting capacity of ten tons. Ah, Oliver, I cannot tell you what a great relief has come to me now that I know my life's work is crowned with success."
