Mr. Burnside had no head for mechanics, but Overholt had already made an invention which was considered very successful, though he had got little or nothing for it. The mechanic who had helped him in its construction had stolen his principal idea before the device was patented, and had taken out a patent for a cheap little article which every one at once used, and which made a fortune for him. Overholt's instrument took its place in every laboratory in the world; but the mechanic's labour-saving utensil took its place in every house. It was on the strength of the valuable tool of science that Mr. Burnside had invested two thousand dollars in the Air-Motor without really having the smallest idea whether it was to be a machine that would move the air, or was to be moved by it. A number of business men had done the same thing.
Then, at a political dinner in a club, three of the investors had dined at the same small table, and in an interval between the dull speeches, one of the three told the others that he had looked into the invention and that there was nothing in Overholt's motor after all. Overholt was crazy.
"It's like this," he had said. "You know how a low-pressure engine acts; the steam does a part of the work and the weight of the atmosphere does the rest. Now this man Overholt thinks he can make the atmosphere do both parts of the work with no steam at all, and as that's absurd, of course, he won't get any more of my money. It's like getting into a basket and trying to lift yourself up by the handles."
Each of the two hearers repeated this simple demonstration to at least a dozen acquaintances, who repeated it to dozens of others; and after that John Henry Overholt could not raise another dollar to complete the Air-Motor.
Mr. Burnside's refusal had been definite and final, and he had been the last to whom the investor had applied, merely because he was undoubtedly the most close-fisted man of business of all who had invested in the invention.
Overholt saw failure before him at the very moment of success, with the not quite indifferent accompaniment of starvation. Many a man as good as he has been in the same straits, even more than once in life, and has succeeded after all, and Overholt knew this quite well, and therefore did not break down, nor despair, nor even show distinct outward signs of mental distress.
