So they went stepping off to work together, mother and son. A mother of twenty-five years before would have watched her son with tear-dimmed eyes from the vine-wreathed porch of a cottage. There was no watching a son from the tenth floor of an up-town apartment house. Besides, she had her work to do. The subway swallowed both of them. Together they jostled and swung their way down-town in the close packed train. At the Twenty-third Street station Jock left her. "You'll have dinner to-night with a full-fledged professional gent," he bragged, in his youth and exuberance and was off down the aisle and out on the platform. Emma McChesney managed to turn in her nine-inch space of train seat so that she watched the slim, buoyant young figure from the window until the train drew away and he was lost in the stairway jam. Just so Rachel had watched the boy Joseph go to meet the Persian caravans in the desert. "Don't let them buffalo you, Jock," Emma had said, just before he left her. "They'll try it. If they give you a broom and tell you to sweep down the back stairs, take it, and sweep, and don't forget the corners. And if, while you're sweeping, you notice that that kind of broom isn't suited to the stairs go in and suggest a new kind. They'll like it." Brooms and back stairways had no place in Jock McChesney's mind as the mahogany and gold elevator shot him up to the fourteenth floor of the great office building that housed the Berg, Shriner Company. Down the marble hallway he went and into the reception room. A cruel test it was, that reception room, with the cruelty peculiar to the modern in business. With its soft-shaded lamp, its two-toned rug, its Jacobean chairs, its magazine-laden cathedral oak table, its pot of bright flowers making a smart touch of color in the somber richness of the room, it was no place for the shabby, the down-and-out, the cringing, the rusty, or the mendicant. Jock McChesney, from the tips of his twelve-dollar shoes to his radiant face, took the test and stood it triumphantly. He had entered with an air in which was mingled the briskness of assurance with the languor of ease. There were times when Jock McChesney was every inch the son of his mother. There advanced toward Jock a large, plump, dignified personage, a personage courteous, yet reserved, inquiring, yet not offensively curious--a very Machiavelli of reception-room ushers. Even while his lips questioned, his eyes appraised clothes, character, conduct. "Mr. Hupp, please," said Jock, serene in the perfection of his shirt, tie, collar and scarf pin, upon which the appraising eye now rested. "Mr. McChesney." He produced a card. "Appointment?" "No--but he'll see me." But Machiavelli had seen too many overconfident callers. Their very confidence had taught him caution. "If you will please state your--ah--business--" Jock smiled a little patient smile and brushed an imaginary fleck of dust from the sleeve of his very correct coat.
