When he had finished his supper, and lifted the tray to the other end of the great oak dining-table, he got out his books again, put fresh wood on the fire, trimmed his lamp, and set himself down to a spell of real hard work. He went on without pause till about eleven o'clock, when he knocked off for a bit to fix his fire and lamp, and to make himself a cup of tea. He had always been a tea-drinker, and during his college life had sat late at work and had taken tea late. The rest was a great luxury to him, and he enjoyed it with a sense of delicious, voluptuous ease. The renewed fire leaped and sparkled, and threw quaint shadows through the great old room; and as he sipped his hot tea he revelled in the sense of isolation from his kind. Then it was that he began to notice for the first time what a noise the rats were making.
