At dinner Lillian asked him no questions about his interview with Mrs. Crane, and he volunteered no information. She was not surprised, however, when he said he would not stop for a cigar, as he was going over to the Physics laboratory.

He walked through the park, past the old house and across the north end of the campus, to a building that stood off by itself in a grove of pine-trees. It was constructed of red brick, after an English model. The architect had had a good idea, and he very nearly succeeded in making a good thing, something like the old Smithsonian building in Washington. But after it was begun, the State Legislature had defeated him by grinding down the contractor to cheap execution, and had spoiled everything, outside and in. Ever since it was finished, plumbers and masons and carpenters had been kept busy patching and repairing it. Crane and St. Peter, both young men then, had wasted weeks of time with the contractors, and had finally gone before the Legislative committee in person to plead for the integrity of that building. But nothing came of all their pains. It was one of many lost causes.

St. Peter entered the building and went upstairs to a small room at the end of a chain of laboratories. After knocking, he heard the familiar shuffle of Crane’s carpet slippers, and the door opened.

Crane was wearing a grey cotton coat, shrunk to a rag by washing, though he wasn’t working with fluids or batteries tonight, but at a roll-top desk littered with papers. The room was like any study behind a lecture room; dusty books, dusty files, but no apparatus — except a spirit-lamp and a little saucepan in which the physicist heated water for his cocoa at regular intervals. He was working by the glare of an unshaded electric bulb of high power — the man seemed to have no feeling for comfort of any kind. He asked his visitor to sit down, and to excuse him for a moment while he copied some entries into a note-book.

St. Peter watched him scribbling with his fountain pen. The hands that were so deft in delicate manipulations were white and soft-looking; the fingers long and loosely hung, stained with chemicals, and blunted at the tips like a violinist’s. His head was square, and the lower part of his face was covered by a reddish, matted beard. His pale eyes and fawn-coloured eyebrows were outbalanced by his mouth, his most conspicuous feature. One always remembered about Crane that unexpected, startling red mouth in a setting of kinky beard. The lips had no modelling, they were as thick at the corners as in the middle, and he spoke through them rather than with them. He seemed painfully conscious of them.

St. Peter saw no use in beating about the bush. As soon as Crane put down his pen, he remarked that Mrs. Crane had been to see him that afternoon. His colleague flushed, took up a large celluloid paper-knife, and began shutting and unshutting his hands about the blade.

“I want to know exactly how you feel about this, and what the facts are,” St. Peter began. “We’ve never discussed it before, and there may be things I know nothing about. Did Tom ever say that he meant you to have a share in his profits, if there were any?”

“No, not exactly. Not exactly that.” Dr. Crane moved his shoulders about in his tight coat and looked embarrassed and unhappy. “More than once he said, in a general way, that he hoped it would go, on my account as well as on his own, and that we would use the income for further experiments.”

“Did he talk much about the possible commercial value of the gas while he was trying to make it?”

“Not much. No, very seldom. Perhaps not more than half a dozen times in the three years he was working in my laboratory. But whenever he did, he spoke as if there would be something in it for both of us if our gas became remunerative.”

“Just how much was it ‘our gas,’ Crane?”

“Strictly speaking, of course, it wasn’t. The idea was Outland’s. He benefited by my criticism, and I often helped him with his experiments. He never acquired a nice laboratory technic. He would fail repeatedly in some perfectly sound experiment because of careless procedure.”

“Do you think he would have arrived at his results without your help?”

Dr. Crane was clenching the paper-knife with both hands. “That I cannot say. He was impatient. He might have got discouraged and turned to something else. He would have been much slower in getting his results, at any rate. ‘His conception was right, but very delicate manipulation was necessary, and he was a careless experimentor.”

St. Peter felt that this was becoming nothing less than cross-examination. He tried to change the tone of it.

“I want to see you get recognition and compensation for whatever part you had in his experiments, if there’s any way to get it. But you’ve been neglectful, Crane. You haven’t taken the proper steps. Why in the world didn’t you have some understanding with Tom when he was getting his patent? You knew all about it.”

“It didn’t occur to me then. We’d finished the experiments, and I put them out of my mind. I was trying to concentrate on my own work. His results weren’t as interesting scientifically as I’d expected them to be.”
