In the two months of separation that ensued before Marjorie was one-and-twenty, Trafford's mind went through some remarkable phases. At first the excitement of his passion for Marjorie obscured everything else, then with his return to London and his laboratory the immense inertia of habit and slowly developed purposes, the complex yet convergent system of ideas and problems to which so much of his life had been given, began to reassert itself. His love was vivid and intense, a light in his imagination, a fever in his blood; but it was a new thing; it had not crept into the flesh and bones of his being, it was away there in Surrey; the streets of London, his home, the white-walled chamber with its skylight and high windows and charts of constants, in which his apparatus was arranged, had no suggestion of her. She was outside--an adventure--a perplexing incommensurable with all these things. He had left Buryhamstreet with Marjorie riotously in possession of his mind. He could think of nothing but Marjorie in the train, and how she had shone at him in the study, and how her voice had sounded when she spoke, and how she stood and moved, and the shape and sensation of her hands, and how it had felt to hold her for those brief moments in the wood and press lips and body to his, and how her face had gleamed in the laced shadows of the moonlight, soft and wonderful. In fact, he thought of Marjorie. He thought she was splendid, courageous, wise by instinct. He had no doubt of her or that she was to be his--when the weeks of waiting had passed by. She was his, and he was Marjorie's; that had been settled from the beginning of the world. It didn't occur to him that anything had happened to alter his life or any of his arrangements in any way, except that they were altogether altered--as the world is altered without displacement when the sun pours up in the east. He was glorified--and everything was glorified. He wondered how they would meet again, and dreamt a thousand impossible and stirring dreams, but he dreamt them as dreams. At first, to Durgan's infinite distress, he thought of her all day, and then, as the old familiar interests grappled him again, he thought of her in the morning and the evening and as he walked between his home and the laboratory and at all sorts of incidental times--and even when the close-locked riddles of his research held the foreground and focus of his thoughts, he still seemed to be thinking of her as a radiant background to ions and molecules and atoms and interwoven systems of eddies and quivering oscillations deep down in the very heart of matter.
