Hallam looked up in surprise. Amy's acquaintance with the superintendent had begun most auspiciously, and he had desired to be considered her "friend," even as now her brother's. Yet since her coming to work in the mill, Mr. Metcalf had not exchanged a dozen sentences with her. She saw him daily, almost hourly. He was everywhere present about the great buildings. In no department was anybody sure of the time of his appearance, yet not one was overlooked. This kept the operators keyed to an expectancy which brought out from them their best, for the approbation of this observant 'boss' meant much to each. Yet he rarely spoke in a harsh tone to any, nor had any ever heard him utter an oath. This, in itself, gave him a distinction from all other mill superintendents under which most of these operatives had served, and added, it may be, a greater awe to their respect of him. "I've been color mixer in a carpet mill these forty years, and Metcalf's the only 'Supe' I ever knew could run one without swearing," often remarked the master of the dyeing room. "He does; and a fellow may count himself lucky to work under such a man." The color mixer, being a most important personage in the institution, had influence among his _confrères_, with good reason. His trade was an art and a secret. Like all trade secrets it commanded its own price. He was said to enjoy a salary "among the thousands," and to have rejected even richer offers for the sake of the peaceful discipline at Ardsley. Then the two visited the "setting room," where the mill girls reached the highest promotion possible in their business. The "setting" is the arrangement upon frames of the threads of the carpet, perfectly adjusted. A girl sits upon each side the frame, which holds from two hundred threads to slightly an advance upon that number. It is clean and dainty work, and the operator is fortunate who can secure the position. It is the same "thread" which, drawn over wires, in the weaver's hands, makes the looplike surface of Brussels carpeting, which was the only sort manufactured at Ardsley. "You find it fascinating, don't you? So did Amy. Well, if you work here, in any department, you will have opportunity to study the whole science, from beginning to end. But I'm to meet Mr. Wingate in ten minutes in his private office. Let us go back." Amy, away up on the fourth floor where she worked, knew nothing of this visit, and was a little dismayed when she received a summons to go down "to the 'Supe's' room for her nooning." She was now alone with Mary at her "jenny," and had already become so expert that those who understood such matters prophesied she would soon be promoted to the "twisting and doubling." That very morning the "boss" of their room had said to her:--
