Wilkinson cleared his throat and bent forward with an air of concentration, meant to indicate that he was marshaling his ideas. Then he said in a hushed and confidential tone: "What do you know of trolley systems?"

Miss Maitland looked at him in surprise.

"Goodness, Charlie!" she said; "I know there are such things—the term is perfectly familiar. I have always supposed that trolley cars were part of trolley systems, but I should hesitate to go very far beyond that statement."

The young man nodded gravely.

"You are right. Your information, so far as it extends, is absolutely correct, but it hardly goes far enough. Trolley cars belong to trolley companies which operate trolley systems. That's very well put, don't you think?"

"Very. Go on—I'm awfully interested."

"I'll put it a little more simply. The scientific attitude is too difficult to maintain. And besides, that was just about as far as I could go scientifically, anyway. I had much better deal with concrete facts—or with what I hope to convert into them. Don't you agree? Although I felt rather well in my academic habiliments."

"Much better," Miss Maitland promptly agreed. "And there would be the additional advantage that I would quite likely know what you were talking about, which would not be at all a certainty if you insisted on retaining your scientific manner."

"It's this way, then," said her companion. "It's this way. John M. Hurd, Isabel's father, my step-uncle, Mrs. Hurd's husband—John M. Hurd, in short, is the President of the most important trolley system in this vicinity, the Massachusetts Light, Heat, and Traction Company. He is also, ex-officio, chairman of the board of directors, and except for some dynamos, cars, conductors, tracks, and other equipment, he is the trolley system."

"That sounds like Mr. Hurd," the girl acknowledged.
