"The thought may be wonderful, young man. I'll not pass on that. But plainly I can't see where the commercial value of the machine comes in."

David and Suzanna fell back from the cloud which gathered on the inventor's face.

"The commercial value!" he cried. "Have I spent my life working merely that the capitalist may make more money? I tell you, sir, that I have worked only for the betterment of the race. And to you, John Massey, I am giving the great opportunity."

"Well, out with it. Where's the great opportunity?" asked Mr. Massey testily. "To my mind you haven't an article with a wide enough appeal."

"Wide enough appeal!" cried the inventor. "My dear sir, it has an appeal world-wide, and you are to make it of such appeal." He paused to continue impressively: "John Massey, I offer you the opportunity of endowing an institution which shall be built to use my machine. To that institution young men of impecunious parents may come to discover their leading talent."

"If there is a leading talent, will it take your machine to discover it?" asked John Massey.

"In most cases, yes. How many young men fail to discover until too late what life work they are best fitted for, unless they possess a talent so strong that it amounts to genius. How many of necessity are sent out into the world at an unformed age to slavery in order that they and their dependents may live. What chance or time have they, grinding away at any work which brings a dollar, to know for what work they are most suited. They know only when it is too late that they are bound by chains, crucifying themselves daily at tasks they hate, and for which they have no natural adaptation."

He paused, only to continue with fire: "Or, if they have ambitions, know what they would best like to do, how helpless they are. No money, no opportunity."

"I'll warrant, Mr. Massey," put in David, "that there are many men employed in your steel mills who by natural inclination are totally unfitted for their jobs. Now, wouldn't scientific investigation in their early manhood have helped to find for them the right place and so added to their happiness?"

"Well, I'm not interested in that part of the question; their happiness has nothing to do with me," returned John Massey. "I pay 'em their wages and that's enough. And I don't believe that every man is born with a special talent. They all look alike to me mostly."
