Conolly stared rather at this question, and then shook his head. “I dont know anything about that,” he said; “I am only a workman. Perhaps Lord Carbury can tell you: he has read a good deal about it.”

Marian looked incredulously at him. “I am sure you are joking,” she said. “Lord Carbury says you know ever so much more than he does. I suppose I asked a stupid question. What are those reels of green silk for?”

“Ah,” said Conolly, relaxing. “Come now, I can tell you that easily enough. I dont know what it is, but I know what it does, and I can lay traps to catch it. Here now, for instance——”

And he went on to deliver a sort of chatty Royal Institution Children’s Lecture on Electricity which produced a great impression on Marian, who was accustomed to nothing better than small talk. She longed to interest him by her comments and questions, but she found that they had a most discouraging effect on him. Redoubling her efforts, she at last reduced him to silence, of which she availed herself to remark, with great earnestness, that science was a very wonderful thing.

“How do you know?” he said, a little bluntly.

“I am sure it must be,” she replied, brightening; for she thought he had now made a rather foolish remark. “Is Lord Carbury a very clever scientist?”

Conolly looked just grave enough to suggest that the question was not altogether a discreet one. Then, brushing off that consideration, he replied:

“He has seen a great deal and read a great deal. You see, he has great means at his disposal. His property is as good as a joint-stock company at his back. Practically, he is very good, considering his method of working: not so good, considering the means at his disposal.”

“What would you do if you had his means?”

Conolly made a gesture which plainly signified that he thought he could do a great many things.
