eye is like an ear for music, a facility for languages, or the power of drawing from nature; all the application in the world will not do in years what any one of these does instantly, spontaneously, instinctively, without the smallest effort. You cannot make talent out of a combination of taste and industry. You cannot train a cart-horse to trot a mile in a little over a minute.
Newton returned, bringing his materials, to describe which would be profitless, if it were possible. He had everything littered together in two battered deal candle-boxes, including the broken soup-plate containing the flour paste, a loathely, mouldering little mess that diffused a nauseous odour, distinctly perceptible through that of the unpronounceable chemical on which the Air-Motor was to depend for its existence.
The light outside was failing in the murky November air, and Overholt lit the big reflecting lamp that hung over the work-table. There was another above the lathe, for no gas or electricity was to be had so far from the town, and one of old Barbara's standing causes of complaint against Overholt was his reckless use of kerosene—she thought it would be better if he had more fat turkeys and rump-steaks and less light.
So the man and the boy "went to work to play" at building the City of Hope, for at least an hour before supper and half an hour after it, almost every day; and with the boy's marvellous memory and the father's skill, and the delicious profusion of fresh material which Newton kept finding in every corner of the workshop, it grew steadily, till it was a little work of art in its way. There were the ups and downs, the crooked old roads and lanes and the straight new streets, the little wooden cottages and the big brick houses, and there was the grassy common with its trees and its tiny iron railing; and John Henry easily made posts to carry the trolley wires, which had seemed an impossible dream to the boy, beyond all realisation; and one day, when the inventor seemed farther from the tangent-balance than ever, he spent a whole afternoon in making a dozen little trolley-cars that ran on real wheels, made by sawing off little sections from a lead pencil, which is the best thing in the world for that, because the lead comes out and leaves nice round holes for the axles. When the first car was painted red and yellow and ran up and down Main Street, guided by the wire above and only needing one little artificial push to send it either way, it looked so real that the boy was in ecstasies of delight.
"It's worth while to be a great inventor to be able to make things like that!" he cried, and Overholt was as much pleased by the praise as an opera singer is who is called out three times before the curtain after the first act.
So the little City of Hope grew, and they both felt that Hope herself was soon coming to dwell therein, if she had not come already.

HOW THEY MADE BRICKS WITHOUT STRAW
But then something happened; for Overholt was tormented by the vague consciousness of a coming idea, so that he had headaches and could not sleep at night. It flashed upon him at last one evening when Newton was in bed and he was sitting before his motor, wishing he had the thousand dollars which would surely complete it, even if he used the most expensive materials in the market.
The idea which developed suddenly in all its clearness was that he had made one of the most important parts of the machine exactly the converse of what it should be; what was on the right should have been on the left, and what was down should certainly have been up. Then the engine would work, even if the tangent-balance were a very poor affair indeed.
The particular piece of brass casting which was the foundation of that part had been made in New York, and, owing to the necessity for its being finished very accurately and machine planed and turned, it had cost a great deal of money. Already it had been made and spoilt three times over, and now it was perfectly clear that it must be cast over again in a reversed form. It was quite useless to make the balance yet, for it would be of no use till the right casting was finished; it would have to be reversed too, and the tangent would apply to a reversed curve.
He had no money for the casting, but even before trying to raise the cash it was necessary to make the wooden model. He could do that, and he set to work to sketch the drawing within five minutes after the idea had once flashed upon him. As his eye followed the lines made by his pencil, he became more and more convinced that he was right. When the rough sketch was done he looked up at the engine. Its familiar features seemed to be drawn into a diabolical grimace of contempt at his stupidity, and it looked as if it were conscious and wanted to throw the wrongly-made piece at his head. But he was overwrought just then and could have fancied any folly.
He rose, shook himself, and then took a long pull at a black bottle that always stood on a shelf. When a man puts a black bottle to his lips, tips it up, and takes down several good pulls almost without drawing breath, most people suppose that he is a person of vicious habits. In Overholt's case most people would have been wrong. The black bottle contained cold tea; it was strong, but it was only tea, and that is the finest drink in the world for an inventor or an author to work on. When I say an author I mean a poor writer of prose, for I have always been told that all poets are either mad, or bad, or both. Many of them must be bad, or they could not write such atrocious poems; but madness is different; perhaps they read their own verses.
When Overholt had swallowed his cold tea, he got out his drawing materials, stretched a fresh sheet of thick draughtsman's paper on the board, and sat down between the motor that would not move and the little city in which Hope had taken lodgings for a while, and he went to work with ruler, scale and dividers, and the hard wood template for drawing the curves he had constructed for the tangent-balance by a very abstruse mathematical calculation. That was right, at all events, only, as it was to be reversed, he laid it on the paper with the under-side up.
He worked nearly all night to finish the drawing, slept two hours in a battered Shaker rocking-chair by the fire, woke in broad daylight, drank more cold tea, and went at once to his lathe, for the new piece was in the nature of a cylinder, and a good deal of the work could be done by turning.
The chisel and the lathe seemed to be talking to each other over the block of wood, and what they said rang like a tune in John Henry's head.
"Bricks without straw, bricks without straw, bricks without straw," repeated the lathe regularly, at each revolution, and when it said "bricks" the treadle was up, and when it said "straw" the treadle was down, for of course it was only a foot lathe, though a good one. "Sh—sh—sh—ever so much better than no bricks at all—sh—sh—sh," answered the sharp chisel as it pressed and bit the wood, and made a little irregular clattering when it was drawn away, and then came forward against the block again with a long hushing sound; and Overholt was inclined to accept its opinion, and worked on as if an obliging brassfounder were waiting outside to take the model away at once and cast it for nothing, or at least on credit.
But no such worthy and confiding manufacturer appeared, even on the evening of the second day, when the wooden model was beautifully finished and ready for the foundry. While the inventor was busy, Newton had worked alone in a corner when he had time to spare from his lessons, but he understood what was going on, and he did not accomplish much beyond painting the front of the National Bank in the City of Hope and planning a possible Wild West Show to be set up on the outskirts; the tents would be easy to make, but the horses were beyond his skill, or his father's; it would not be enough that they should have a leg at each corner and a head and a tail.
He understood well enough what was the matter, for he had seen similar things happen before. A pessimist is defined to be a person who has lived with an optimist, and every inventor is that. Poor Newton had seen that particular part of the engine spoiled and made over three times, and he understood perfectly that it was all wrong again and must be cast once more. But
