As man evolves what changes will he undergo in a thousand years? A million or more? ExcerptThere were three of us in Pollard's house on that night that I try vainly to forget. Dr. John Pollard himself, Hugh Dutton and I, Arthur Wright--we were the three. Pollard met that night a fate whose horror none could dream; Dutton has since that night inhabited a state institution reserved for the insane, and I alone am left to tell what happened.It was on Pollard's invitation that Dutton and I went up to his isolated cottage. We three had been friends and room-mates at the New York Technical University. Our friendship was perhaps a little unusual, for Pollard was a number of years older than Dutton and myself and was different in temperament, being rather quieter by nature. He had followed an intensive course of biological studies, too, instead of the ordinary engineering courses Dutton and I had taken.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.
