“So you let the Old Woman keep the work-sheet for you, huh? Well, I never butt into anybody’s business. I’m staying at the Berrington Hotel, room 617—’member that, 617—and you might try and ’phone me before ten to-morrow. Say, that’s one grand sweet song of a cutie you got on the door here. What-cha-think? How’s chances on dragging her out to feed and shake a hoof with Uncle Clif?”

As primly as the oldest, most staid scientist in the Institute, Martin protested, “Oh, she belongs to a very nice family. I don’t think I should try it. Really, I’d rather you didn’t.”

Clif’s gaze was sharp, for all its fattiness.

With excessive cordiality, with excessive applause when Clif remarked, “You better go back to work and put some salt on a coupla bacteria’s tails,” Martin guided him to the reception-room, safely past the girl clerk, and to the elevator.

For a long time he sat in his office and was thoroughly wretched.

He had for years pictured Clif Clawson as another Terry Wickett. He saw that Clif was as different from Terry as from Rippleton Holabird. Terry was rough, he was surly, he was colloquial, he despised many fine and gracious things, he offended many fine and gracious people, but these acerbities made up the haircloth robe wherewith he defended a devotion to such holy work as no cowled monk ever knew. But Clif—

“I’d do the world a service by killing that man!” Martin fretted. “Phageotherapy at a yegg sanitarium! I stand him only because I’m too much of a coward to risk his going around saying that ‘in the days of my Success, I’ve gone back on my old friends.’ (Success! Puddling at work! Dinners! Talking to idiotic women! Being furious because you weren’t invited to the dinner to the Portuguese minister!) No. I’ll ’phone Clif we can’t have him at the house.”

Over him came remembrance of Clif’s loyalty in the old barren days, and Clif’s joy to share with him every pathetic gain.

“Why should he understand my feeling about phage? Was his scheme any worse than plenty of reputable drug-firms? How much was I righteously offended, and how much was I sore because he didn’t recognize the high social position of the rich Dr. Arrowsmith?”

He gave up the question, went home, explained almost frankly to Joyce what her probable opinion of Clif would be, and contrived that Clif should be invited to dinner with only the two of them.
