As Dutton and I drove northward along the Hudson on that afternoon, we found ourselves reviewing what we knew of Pollard's career. We had known of his taking his master's and doctor's degrees, and had heard of his work under Braun, the Vienna biologist whose theories had stirred up such turmoil. We had heard casually, too, that afterwards he had come back to plunge himself in private research at the country-house beside the Hudson he had inherited. But since then we had had no word from him and had been somewhat surprised to receive his telegrams inviting us to spend the weekend with him.

It was drawing into early-summer twilight when Dutton and I reached a small riverside village and were directed to Pollard's place, a mile or so beyond. We found it easily enough, a splendid old pegged-frame house that for a hundred-odd years had squatted on a low hill above the river. Its outbuildings were clustered around the big house like the chicks about some protecting hen.

Pollard himself came out to greet us. "Why, you boys have grown up!" was his first exclamation. "Here I've remembered you as Hughie and Art, the campus trouble-raisers, and you look as though you belong to business clubs and talk everlastingly about sales-resistance!"

"That's the sobering effect of commercial life," Dutton explained, grinning. "It hasn't touched you, you old oyster — you look the same as you did five years ago."

He did, too, his lanky figure and slow smile and curiously thoughtful eyes having changed not a jot. Yet Pollard's bearing seemed to show some rather more than usual excitement and I commented on it.

"If I seem a little excited it's because this is a great day for me," he answered.

"Well, you are in luck to get two fine fellows like Dutton and me to trail up to this hermitage of yours," I began, but he shook his head smilingly.

"I don't refer to that. Art, though I'm mighty glad you've come. As for my hermitage, as you call it, don't say a word against it. I've been able to do work here I could never have done amid the distractions of a city laboratory."

His eyes were alight. "If you two knew what — but there, you'll hear it soon enough. Let's get inside — I suppose you're hungry?"

"Hungry — not I," I assured him. "I might devour half a steer or some trifle like that, but I have really no appetite for anything else today."
