The recall of molecular physics and particularly of the internal condition of colloids to something like their old importance in his life was greatly accelerated by the fact that a young Oxford don named Behrens was showing extraordinary energy in what had been for a time Trafford's distinctive and undisputed field. Behrens was one of those vividly clever energetic people who are the despair of originative men. He had begun as Trafford's pupil and sedulous ape; he had gone on to work that imitated Trafford's in everything except its continual freshness, and now he was ransacking every scrap of suggestion to be found in Trafford's work, and developing it with an intensity of uninspired intelligence that most marvellously simulated originality. He was already being noted as an authority; sometimes in an article his name would be quoted and Trafford's omitted in relation to Trafford's ideas, and in every way his emergence and the manner of his emergence threatened and stimulated his model and master. A great effort had to be made. Trafford revived the drooping spirits of Durgan by a renewed punctuality in the laboratory. He began to stay away from home at night and work late again, now, however, under no imperative inspiration, but simply because it was only by such an invasion of the evening and night that it would be possible to make headway against Behren's unremitting industry. And this new demand upon Trafford's already strained mental and nervous equipment began very speedily to have its effect upon his domestic life. It is only in romantic fiction that a man can work strenuously to the limit of his power and come home to be sweet, sunny and entertaining. Trafford's preoccupation involved a certain negligence of Marjorie, a certain indisposition to be amused or interested by trifling things, a certain irritability.... § 2 And now, indeed, the Traffords were coming to the most difficult and fatal phase in marriage. They had had that taste of defiant adventure which is the crown of a spirited love affair, they had known the sweetness of a maiden passion for a maid, and they had felt all those rich and solemn emotions, those splendid fears and terrible hopes that weave themselves about the great partnership in parentage. And now, so far as sex was concerned, there might be much joy and delight still, but no more wonder, no fresh discoveries of incredible new worlds and unsuspected stars. Love, which had been a new garden, an unknown land, a sunlit sea to launch upon, was now a rich treasure-house of memories. And memories, although they afford a perpetually increasing enrichment to emotion, are not sufficient in themselves for the daily needs of life.
