and down, but never a stop did they advance! The power was there, sufficient to run a saw-mill, every thing seemed to work, but the thing wouldn't go!
The boy was not ready to despair. He seated himself on the bench beside the machine, and keeping up a moderate supply of steam, throwing in bits of wood, and letting in water, when necessary, he carefully watched the movement for several hours.
Occasionally, Johnny walked slowly back and forth, and with his eyes upon the 'stately stepping,' endeavored to discover the precise nature of that which was lacking in his machine.
At length it came to him. He saw from the first that it was not merely required that the steam man should lift up its feet and put them down again, but there must be a powerful forward impulse at the same moment. This was the single remaining difficulty to be overcome. It required two weeks before Johnny Brainerd succeeded. But it all came clear and unmistakable at last, and in this simple manner:
(Ah! but we cannot be so unjust to the plodding genius as to divulge his secret. Our readers must be content to await the time when the young man sees fit to reveal it himself.)
When the rough figure was fairly in working order, the inventor removed everything from around it, so that it stood alone in the center of his shop. Then he carefully let on steam.
Before he could shut it off, the steam man walked clean through the side of his shop, and fetched up against the corner of the house, with a violence that shook it to its foundation. In considerable trepidation, the youngster dashed forward, shut off steam, and turned it round. As it was too cumbersome for him to manage in any other way, he very cautiously let on steam again, and persuaded it to walk back into the shop, passing through the same orifice through which it had emerged, and came very nigh going out on the opposite side again.
The great thing was now accomplished, and the boy devoted himself to bringing it as near perfection as possible. The principal thing to be feared was its getting out of order, since the slightest disarrangement would be sufficient to stop the progress of the man.
Johnny therefore made it of gigantic size, the body and limbs being no more than 'Shells,' used as a sort of screen to conceal the working of the engine. This was carefully painted in the manner mentioned in another place, and the machinery was made as strong and durable as it was possible for it to be. It was so constructed as to withstand the severe jolting to which it necessarily would be subjected, and finally was brought as nearly perfect as it wag possible to bring a thing not possessing human intelligence.
By suspending the machine so that Its feet were clear of the floor, Johnny Brainerd ascertained that under favorable circumstances It could run very nearly sixty miles an hour. It could easily do that, and draw a car connected to it on the railroad, while on a common road it could make thirty miles, the highest rate at which he believed it possible for a wagon to be drawn upon land with any degree of safety.
It was the boy's intention to run at twenty miles an hour, while where everything was safe, he would demonstrate the power of the invention by occasionally making nearly double that.
As it was, he rightly calculated that when it came forth, it would make a great sensation throughout the entire United States.
CHAPTER IV.
THE TRAPPER AND THE ARTISAN.
'HELLO, YOUNKER! what in thunder yer tryin' to make?'
Johnny Brainerd paused and looked up, not a little startled by the strange voice and the rather singular figure which stood before him. It was a hunter in half civilized costume, his pants tucked into his immense boot tops, with revolvers and rifles at his waist, and a general negligent air, which showed that he was at home in whatever part of the world he chose to wander.
He stood with his hand in his pocket, chewing his quid, and complacently viewing the operations of the boy, who was not a little surprised to understand how he obtained entrance into his shop.
'Stopped at the house to ax whar old Washoe Pete keeps his hotel,' replied the stranger, rightly surmising the query which was agitating him, 'and I cotched a glimpse of yer old machine. Thought I'd come in and see what in blazes it war. Looks to me like a man that's gwine to run by steam.'
'That's just what it is,' replied the boy, seeing there was no use in attempting to conceal the truth from the man.
'Will it do it?'
'Yes, sir.'
'Don't think you mean to lie, younker, but I don't believe
