the town they met the postman. As a rule Barbara got the mail when she went to market, and Overholt was not even going to ask the man if there were any letters for him. But the postman stopped him. There was one from his wife, and it was registered. He signed the little receipt for it, the man passed them on his rounds, and they slackened their pace as Overholt broke the seal.
He uttered a loud exclamation when he had glanced at the contents, and he stood still in the road. Newton stared at him in surprise.
"A thousand dollars!" he cried, overcome with amazement. "A thousand dollars! Oh, Helen, Helen—you've saved my life!"
He got to the side of the road and leaned against the fence, clutching the letter and the draft in his hand, and gazing into his son's face, half crazy with delight.
"She's saved it all for me, boy. Do you understand? Your mother has saved all her salary for the Motor, and here it is! Look at it, look at it! It's success, it's fame, it's fortune for us all! Oh, if she were only here!"
Newton understood and rejoiced. He forgot his poor little attempt to help, and his own disappointment, and everything except the present glorious truth—not unadorned by the pleasant vision of the Christmas turkey, vast now, and smoking, and flanked by perfect towers of stiff cranberry jelly, ever so much better than mere liquid cranberry sauce; in the middle distance, behind the noble dish, a noble pyramid of ice-cream raised its height, and yellow cream-cakes rose beyond, like many little suns on the far horizon. In that first moment of delight there was almost a Christmas tree, and the mother's face beside it; but that was too much; they faded, and the rest remained, no mean forecast of a jolly time.
"That's perfectly grand!" Newton cried when he got his breath after his surprise at the announcement. "Besides, I told you so. What did I say? She wouldn't let you give up the Motor! I knew she wouldn't! Who's right now, father? That's something like what I call a mother! But then she always was!"
He was slightly incoherent, but that did not matter at all. Nothing mattered. In his young beatific vision he saw the bright wheel going round and round in a perfect storm of turkeys, and it was all his mother's doing.
Overholt only half heard, for he had been reading the letter; the letter of a loving wife who believes in her husband and gives him all she has for his work, with every hope, every encouragement, and every blessing and Christmas wish.
"There's no time to be lost!" Overholt said, repeating the words he had spoken in a very different mood and tone half an hour earlier. "I won't walk on with you, my boy, for I must go back and get the wooden model for the foundry. They'll do it for me now, fast enough! And I can pay what I owe at the bank, and there will be plenty left over for your Christmas too!"
"Oh, bother my Christmas, father!" answered Newton with a fine indifference which he did not feel. "The Motor's the thing! I want to see that wheel go round for a Christmas present!"
"It will! It shall! It must! I promise you that!" The man was almost beside himself with joy.
No misgiving disturbed him. He had the faith that tosses mountains aside like pebbles, now that the means were in his hand. He had the little fulcrum for his lever, which was all Archimedes required to move the world. He had in him the certainty of being right that has sent millions of men to glory or destruction.
That day was one of the happiest in all his life, either before or, afterwards. He could have believed that he had fallen asleep at the moment when he had quite broken down, and that a hundred years of change had glided by, like a watch in the night, when he opened his wife's letter and wakened in a blaze of joy and hope and glorious activity. Nothing he could remember of that kind could compare with his pride and honourable satisfaction when he walked into the bank two hours afterwards, with his head high, and said he should be glad to take up the note he had signed yesterday and have the balance of the cheque placed to his credit; and few surprises which the partner who had obliged him could recollect, had equalled that worthy gentleman's amazement when the debt was paid so soon.
"If you had only told me that you would be in funds so soon, Mr. Overholt," he said, "I should not have thought of troubling you. Here is your note. Will you kindly look at it and tear it up?"
"I did not know," answered Overholt, doing as he was told.
It is a curious fact that the little note lay in a locked drawer of the partner's magnificent table, instead of being put away in the safe with other and larger notes, where it belonged. It may seem still stranger that, on the books, Overholt's account showed that it had been balanced by a deposit exactly equal to the deficit, made by the partner himself, instead of by crediting the amount of the note. But Overholt never knew this, for a pass-book had always been a mystery to him, and made his head ache. The banker had thought of his face some time after he had gone out with his battered umbrella and his shabby shoulders rounded as under a burden, and somehow the Christmas spirit must have come in quietly and touched the rich man too, though even the stenographer did not see what happened. For he had once been in terrible straits himself, a quarter of a century ago, and some one had helped him just in time, and he knew what it meant to slink out of a big bank, in shabby clothes, his back bowed under the heavy weight of debt and failure.
Overholt never knew; but he expressed his warm thanks for what now seemed a small favour, and with his wooden model of the casting, done up in brown paper, under his arm, he went off to the foundry in Long Island.
Much careful work had been done for him there, and the people were willing to oblige him, and promised that the piece should certainly be ready before Christmas Day, and as much earlier as possible, and should be made with the greatest exactness which the most precise machinery and the most careful work could ensure.
This being settled, Overholt returned to New York and went to two or three places in the Bowery, well known to him, where he bought certain fine tools and pieces of the most perfectly turned steel spring, and several other small objects, which he needed for the construction of the new tangent-balance he had to make for the reversed curve. Finally, he bought a silver watch like the one Newton had sold, and a new pair of skates, presents which the boy certainly deserved, and which would make a very good show at Christmas, when they were to be produced. He felt as if he had come into a large fortune.
Moreover, when he got out of the train at his own station he went into the town, and ordered beforehand the good things for the feast, though there were three weeks still, and he wanted to pay for them in advance, because he felt inside of himself that no one could be quite sure of what might happen in twenty-one days; but the dealers flatly refused to take his money, though they told him what the things would cost. Then Overholt did almost the only prudent thing he had done in his life, for he took the necessary money and five dollars more and sealed it up in an envelope, which he put away in a safe place. The only difficulty would lie in remembering where the place was, so he told Newton about it, and the boy wrote it down on a piece of paper which he pinned up in his own room, where he could see it. There was nothing like making sure of that turkey, he thought. And I may as well say at once that in this matter, at least, no untoward accident occurred, and the money was actually there at the appointed time. What happened was something quite different, and much more unexpected, not to say extraordinary and even amazing; and in spite of all that, it will not take very long to tell.
Meanwhile, before it happened, Overholt and the boy were perfectly happy. All day long the inventor worked at the tangent-balance, till he had brought it to such perfection that it would be affected by a variation of one-tenth of one second in the aggregate speed of ten revolutions, and an increase or decrease of a tenth of a grain in the weight of the volume of the compressed air. It was so sensitive that John Henry and Newton trod cautiously on the floor of the workshop so as not to set it vibrating under the glass clock-shade, where it was kept safe from dust and dampness.
