Lastly, Christmas was coming; the girls she was educating talked of nothing else, and counted the days, and sat up half the night on the edges of each other's beds discussing the beautiful presents they were sure to receive; and a great deal might be written about what they said, but it has nothing to do with this story, except that their chatter helped to fill the air with the Christmas spirit, and with thoughts of giving as well as of receiving. Though they were rather spoiled children, they were generous too, and they laid all sorts of little traps in order to find out what their governess would like best from each of them, for they were fond of her in their way.

Also, Munich is one of the castles which King Christmas still holds in absolute sway and calls his own, and long before he is really awake after his long rest he begins to stir and laugh in his sleep, and the jolly colour creeps up and spreads over his old cheeks before he thinks of opening his eyes, much less of getting up and putting on his crown. And now that he was waking, Helen Overholt felt the old loving longing for her dear ones rising to her womanly heart, and she planned little plans for another and a happier year to come, and meanwhile she bought two or three little gifts to send to the cottage in far Connecticut.

But when she had read about the Berlin professor and his motor and thought of her own John Henry making bricks without straw and bearing up bravely against disappointment, and still writing so cheerfully and hopefully in spite of everything, she simply could not stand it another day. As I have said, King Christmas turned over just before waking, and he put out a big generous hand in his sleep and laid it on her heart. Whenever he does that to anybody, man, woman, or child, a splendid longing seizes them to give all they have to the one child, or woman, or man that each loves best, or to the being of all others that is most in need, or to help the work which seems to each of them the noblest and the best, if they are grown up and are lonely.

This is what happened to Helen Overholt, in spite of her good sense and all her practical resolutions. As long as she had anything to give, John Henry should have it and be happy, and succeed, if success were possible. She had saved most of her salary for a long time past, spending as little as she well could on herself. He should have it all, for love's sake, and because she believed in him, and because Christmas was waking up, and had laid his great affectionate old hand on her.

So it came to pass that when Overholt was pottering over the beautiful motionless Motor, late at night, sure that it would work if he had a little more money, but still more sure that it must be sold for old metal the next morning, to buy bread for the boy, even at that hour help was near, and from the hand he loved best in the world, which would make it ten thousand times sweeter when it reached him.

It was going to be an awful wrench to give up the invention, for now, at the moment of abandoning it, he saw, or thought he saw, that he was right at last, and that it could not fail. It was useless to try it as it was, yet he would, just once more. He adjusted the tangent-balance and the valves; he put in the supply of the chemical with the long name and screwed down the hermetic plug. With the small hand air-pump he produced the first vacuum which was necessary; all was ready, every joint and stuffing-box was lubricated, the spring of the balance was adjusted to a nicety. But the engine would not start, though he turned the fly-wheel with his hand again and again, as if to encourage it. Of course it would not turn alone! He understood perfectly that the one piece on which all depended must be made over again, exactly the other way. That was all!

There was the wooden model of it, all ready for the foundry that would not cast it for nothing. If only the wooden piece would serve for a moment's trial! But he knew that this was folly; it would not stand the enormous strain an instant, and the joints could not possibly be made air-tight.

He was utterly worn out by all he had been through during the long day, and he fell asleep in his chair towards morning, his head on his breast, his feet struck out straight before him, one arm hanging down beside him and his other hand thrust into his pocket. He looked more like a shabby lay figure stuffed with sawdust than like a living man. If Newton had come down and found him lying there under the lamplight he would have started back and shuddered, and waited a while before he could find courage to come nearer.

But the man was only very sound asleep, and he did not wake till the December dawn gleamed through the clear winter's sky and made the artificial light look dim and smoky; and when he opened his eyes it was he himself who started to find himself there in the cold before his great failure, in broad daylight.

Nevertheless, he had slept soundly, and felt better able to face all the trouble that was in store for him. He stirred the embers in the stove, put in some kindling and a supply of coal, and warmed himself, still heavy with sleep, and glad to waken consciously, by degrees, and to feel that his resolution was not going to break down.
