"Not celebrated exactly! At the medical societies they call me the crazy fakir. I don't believe there's a first-class doctor in the city who would take the time to look at this machine. They'd want to know first what some feller in Vienna thought about it. I might starve for all the help I've ever had here! Doctors don't want any one to do things on his own hook: they're jealous, just as jealous as women. But I guess I'm going to show 'em a thing or two not in the books. Let me tell you on the quiet, Miss Venetia,—I'm going over to Paris with this pump of mine and show it off in one of their hospitals. Then you'll see something!"

The girl tried to look intelligent.

"If I can convince some Frenchman or German that I am on to a big idea, why the whole pack of pill-sellers over here will fall into line so quick you can't see 'em."

"Perhaps we shall go over to Paris this summer, too. How I should like to be there when you are, and see you show the pump!"

In her experience there was nothing remarkable in going to Europe: one went to hear an opera, to order a few gowns, to fill out an idle vacation.

"Well, I may have to go steerage, but I'll get there somehow."

While they had been discussing the machine, a small, white-faced man, who looked as if he might be a waiter or some kind of skilled mechanic, had come into the laboratory and nodding to the doctor took a chair at the farther end of the room with the manner of one who was quite at ease in the place. His face, which was aged by illness or care, interested Helen greatly. She watched him while the others talked, wondering what his relation to the doctor could be, whether that of patient or friend. He sat huddled up on his chair, one worn-out boot thrust forward from a ragged trouser leg, curiously scanning the young girl, who seemed in her fresh beauty and rich clothes decidedly out of harmony with the dingy room. When Venetia spoke of going abroad as casually as she might have mentioned going to the country, a sarcastic smile crept over his face. He seemed to possess the full power of patience, as if a varied experience with a buffeting world had taught him to accept rather than to resist. His business there, whatever it might be, could wait, had always waited.

"Hussey, here, is the only feller that I ever found besides myself who has any faith in the old pump," Coburn remarked presently by way of introduction, half turning toward the silent man, and smiling as if he thoroughly enjoyed the joke of having this one convert. "He's always after me to try it on him,—he says he's got something the matter with his lungs,—but I guess it's purely a scientific interest that makes him offer to be the first victim. Gee! Wouldn't I like to take him at his word!"

He worked one of the delicate valves of the machine, squirting through the needle a thin stream of water in the direction of Hussey.

"Why don't you do it then?" the man asked in an indifferent tone. "I'm ready any time you say."
