might, if they were only bigger. Overholt had seen the population in the window of a German toy-shop one day when he was in New York to get a new crocusing wheel for polishing some of the small parts of the engine. They were the smallest doll-people he had ever seen, and were packed by dozens and dozens in Nuremberg toy-boxes, and cost very little, so he bought a quantity of them. At first Newton rather resented them, just because they were only toys, but his father explained to him that models of human figures were almost necessary to models of buildings, to give an idea of the population, and that when architects make coloured sketches of projected houses, they generally draw in one or two people for that reason; and this was perfectly satisfactory to the boy, and saved his dignity from the slight it would have suffered if he had been actually seen amusing himself with mere playthings.
Overholt was divinely happy in anticipation of the final success that was so near, and in the daily work that was making it more and more a certainty, as he thought; and then, when the day was over, he was just as happy with the little City, which was being decorated for Christmas, with wreaths in the windows of the houses, and a great many more holly-trees than had at first been thought of, and numberless little Christmas booths round the common, like those in Avenue A, south of Tompkins Square, in New York, which make you fancy you are in Munich or Prague if you go and see them at the right hour on Christmas Eve.
Before long Overholt received a short note from the President of his old College, simply saying that the latter knew of no opening at present, but would bear him in mind. But that did not matter now.
So the two spent their time very pleasantly during the next weeks; but though Overholt was so hopeful and delighted with his work, he knew that he was becoming nervous and overwrought by the great anticipation, and that he could not stand such a strain very long.
Then, two days before Christmas, he received a note saying that the new piece was finished and had been sent to him by express. That was almost too much happiness to bear, and when he found the heavy case at the station the next morning, and got it put on a cart, his heart was doing queer things, and he was as white as a sheet.

HOW THE WHEELS WENT ROUND AT LAST
The hush of Christmas Eve lay upon the tumble-down cottage, and on the soft fresh snow outside, and the lamps were burning quietly in the workshop, where father and son were sitting before the finished Motor.
The little City was there too, but not between them now, though Newton had taken off its brown paper cover in honour of the great event which was about to take place.
In order to be doubly sure of the result, and dreading even the possibility of a little disappointment, Overholt had decided that he would subject the only chemical substance which the machine consumed to a final form of refinement by heat, melting, boiling and cooling it, all of which would require an hour or more before it was quite ready. He felt like a man who is going to risk his life over a precipice, trusting to a single rope for safety; that one rope must not be even a little chafed; if possible each strand must be perfect in itself, and all the strands must be laid up without a fault. Of the rest, of the machine itself, Overholt felt absolutely sure; yet although a slight impurity in the chemical could certainly not hinder the whole from working, it might interfere with the precision of the revolutions, or even cause the engine to stop after a few hours instead of going on indefinitely, as long as the supply of the substance produced the alternate disturbance of equilibrium which was the main principle on which the machine depended.
That sweetly prophetic evening silence, before the great feast of Good Will, does not come over everything each year, even in a lonely cottage in an abandoned farm in Connecticut, than which you cannot possibly imagine anything more silent or more remote from the noise of the world. Sometimes it rains in torrents just on that night, sometimes it blows a raging gale that twists the leafless birches and elms and hickory trees like dry grass and bends the dark firs and spruces as if they were feathers, and you can hardly be heard unless you shout, for the howling and screaming and whistling of the blast.
But now and then, once in four or five years perhaps, the feathery snow lies a foot deep, fresh-fallen, on the still country-side and in the woods; and the waxing moon sheds her large light on all, and Nature holds her breath to wait for the happy day, and tries to sleep but cannot, from sheer happiness and peace. Indoors the fire is glowing on the wide hearth, a great bed of coals that will last all night, because it is not bitter weather, but only clear and cold and still, as it should be; or if there is only a poor stove, like Overholt's, the wide door is open, and a comfortable and cheery red light shines out from within upon the battered iron plate and the wooden floor beyond; and the older people sit round it, not saying much, but thinking with their hearts rather than with their heads; but small boys and girls know that interesting things have been happening in the kitchen all the afternoon, and are rather glad that the supper was not very good, because there will be the more room for good things to-morrow; and the grown-ups and the children have made up any little differences of opinion they may have had before supper-time, because Good Will must reign, and reign alone, like Alexander; so that there is nothing at all to regret, and nothing hurts anybody any more, and they are all happy in just wishing for King Christmas to open the door softly and make them all great people in his kingdom. But if it is the right sort of house, he is already looking in through the window, to be sure that every one is all ready for him, and that nothing has been forgotten.
Now, although Overholt's cottage was a miserable place for a professor who had lived very comfortably and well in a College town, and although the thirteen-year-old boy could remember several pretty trees, lighted up with coloured candles and gleaming with tinsel and gilt apples, they both felt that this was going to be the greatest Christmas in their lives, because the motionless Motor was going to move, and that would mean everything—most of all to both of them, the end of the mother's exile, and her speedy home-coming. Therefore neither said anything for a long time while the chemical stuff was slowly warming itself and getting ready, inside a big iron pot, of which the cover was screwed on with a high-temperature thermometer sealed in it, and which stood on the top of the stove where Overholt could watch the scale.
He would really have preferred to be alone for the first trial, but it was utterly impossible to think of sending the boy to bed. He was sure of success, it is true, yet he would far rather have been left to himself till that success was no longer in the future, but present; then at last, even if Newton had been asleep, he would have waked him and brought him downstairs again to see his triumph. The lad's presence made him nervous, and suggested a failure which was all but impossible. More than once he was on the point of trying to explain this to Newton, but when he glanced at the young face he could not find it in his heart to speak. If he only asked the boy, as a kindness, to go into the next room for five minutes while the machine was being started, he knew what would happen. Newton would go quietly, without a word, and wait till he was called; but half his Christmas would be spoilt by the disappointment he would try hard to hide. Had they not suffered together, and had not the boy sacrificed the best of his small possessions, dearly treasured, to help in their joint distress? It would be nothing short of brutal to deprive him of the first moment of triumphant surprise, that was going to mean so much hereafter. Yet the inventor would have given anything to be alone. He was overwrought by the long strain that had so often seemed unbearable, and when the liquid that was heating had reached the right temperature and the iron pot had to be taken off the stove, his hands shook so that he nearly dropped it; but Newton did not see that.
"It's wonderful how everything has come out just right!" the boy exclaimed as he looked at the machine. "Out of your three wishes you'll get two, father, for the wheel will go round and I'm going to have a regular old patent, double-barrelled Christmas with a gilt edge!" His similes were mixed, but effective in their way. "And you'll probably get the other wish in half a shake now, for mother'll come right home, won't she?"
"If the trial succeeds," Overholt said, still instinctively seeking to forestall a disappointment he did not expect. "Nothing is a fact until it has happened, you know!"
"Well,"
