For some weeks after the outbreak at the carriage door events ran smoothly in the McPherson house. One day as he stood in the stable door Frank came round the corner of the house and, looking up sheepishly from under his cap, said to Sam: “I understand about the missus. It is the baby coming. We have had four of them at our house,” and Sam, nodding his head, turned and began talking rapidly of his plans to replace the carriages with automobiles. But in the house, in spite of the clearing up of the matter of Sue’s ugliness at the Grovers, a subtle change had taken place in the relationship of the two. Although they were together facing the first of the events that were to be like ports-of-call in the great voyage of their lives, they were not facing it with the same mutual understanding and kindly tolerance with which they had faced smaller things in the past--a disagreement over the method of shooting a rapid in a river or the entertainment of an undesirable guest. The inclination to fits of temper loosens and disarranges all the little wires of life. The tune will not get itself played. One stands waiting for the discord, strained, missing the harmony. It was so with Sam. He began feeling that he must keep a check upon his tongue and that things of which they had talked with great freedom six months earlier now annoyed and irritated his wife when brought into an after-dinner discussion. To Sam, who, during his life with Sue, had learned the joy of free, open talk upon any subject that came into his mind and whose native interest in life and in the motives of men and women had blossomed in the large leisure and independence of the last year, this was trying. It was, he thought, like trying to hold free and open communion with the people of an orthodox family, and he fell into a habit of prolonged silences, a habit that later, he found, once formed, unbelievably hard to break. One day in the office a situation arose that seemed to demand Sam’s presence in Boston on a certain date. For months he had been carrying on a trade war with some of the eastern manufacturers in his line and an opportunity for the settlement of the trouble in a way advantageous to himself had, he thought, arisen. He wanted to handle the matter himself and went home to explain to Sue. It was at the end of a day when nothing had occurred to irritate her and she agreed with him that he should not be compelled to trust so important a matter to another. “I am no child, Sam. I will take care of myself,” she said, laughing. Sam wired his New York man asking him to make the arrangements for the meeting in Boston and picked up a book to spend the evening reading aloud to her. And then, coming home the next evening he found her in tears and when he tried to laugh away her fears she flew into a black fit of anger and ran out of the room.
