As a result of his evil ways Nicholas, in the early years of his marriage, had broken his wife's heart. Her patience had annoyed him, and, had she shown more spirit, her fate might have been a happier one. As it was, she had slipped out of life, mown down with grief as grass is mown with the scythe. And Nicholas had made scant pretence of regretting her, just as he made scant pretence of approving his son. Simon had early betrayed a lack of zest for life--a trait his father could ill tolerate. Therefore, with taunts and gibes, he had made Simon's life miserable through boyhood and early manhood. At first, it may be, he thought by this method to kindle some spirit in the lad, but failing to strike a spark--for Simon remained through all pale and silent, a human riddle to the father,--Nicholas had continued his jeers for sheer malicious joy in the practice. Even now his wit kindled at the thought of Simon, and sure of an appreciative listener, he would make clever satirical remarks about him to his niece, Julia Burgdorf, whenever she put in an appearance. And Julia would match these sallies. To this joking Rachel, in a storm of anger, had endeavoured to put a stop. Now when the pair exchanged their witticisms, it was out of her hearing. Though this old man bore not the slightest resemblance to old David, his age and animation endeared him to Rachel. Then he had once helped her grandfather, a thing she never forgot. Now his voice, which leaped constantly to a childish treble, reached her before she gained the stair's head. A stuttering of the words of his ditty, decided her to postpone her call. Owing to his excitable heart and his years, liquor was forbidden the old man. Resolving to take the housemaid sharply to task for giving Nicholas whiskey, Rachel descended the stairs. Through delicacy she never spoke to Simon of his own or his father's failing. When moved to disapproval of her husband, as she had been that morning, her only reproach was a look. A childhood passed among fishermen had taught her tolerance for this particular weakness. When Simon returned at lunch time, she was nowhere about and he was forced to sit down to the table without her. But she entered before he had finished the first course, and taking her place opposite him, began slowly unfastening her jacket. Wishing to please her, he launched into a description of St. Ives's _pyrometer_. "We melt up different alloys to get the different colour effects," he concluded, "and the colour and intensity of the light bear certain definite relations--" Rachel opened her eyes: "Then it's a success, is it?" Simon avoided her gaze. "Why yes, certainly. In fact," he added, "it's a very ingenious device. A trifling thing, you understand; but it is an instrument for which there is a definite need, and for that reason I should judge he might possibly be able to do something with it."
