Harvey West was a young man. Perhaps had he been older, had his wisdom been salted with experience, he would not have put two and two together without realizing that the sum was four; but then, it is the difference between twenty-six and fifty that makes railroads a possibility. He walked slowly to the elevator and descended to the street. At the corner he paused and looked about, turning over in his mind the singular disappearance of Mr. McNally. “He can't do anything with Tillman's stock,” thought Harvey. “They're solid for us.” But Harvey in his brief business life had not fathomed the devious ways of the chronic capitalist. He knew that commercial honor was honeycombed with corrupt financiering, but to him the corrupt side was more or less vague, and never having soiled his fingers he failed to realize the nearness of the mud. Harvey had yet to learn that in dealing with a municipality or with a legislature, the law of success has but two prime factors, money and speed. He walked slowly over Madison Street and turned into State. Weeks was not in the office, and anyway he wished to clear his mind, if possible, before he talked with him; meanwhile sauntering up the east side of State Street with an eye for the shopping throng. People interested Harvey. He was fond of noting types, and of watching the sandwich-men, beggars, and shoe-string venders. Often at noon he would walk from Randolph Street to Harrison, observing the shifting character of Chicago's great thoroughfare. To Harvey it seemed like a river, starting clear but gradually roiled by the smaller streams that poured in, each a little muddier than the one next north, until it was clogged and stagnant with the scum of the city. But to-day he was going north. The sidewalk was crowded with eager girls and jaded women, keen on the scent of bargains. These amused Harvey, and he smiled as he crossed Washington Street. A moment later the smile brightened. Miss Porter stood on the corner. “Surprised to see me?” she laughed. “Father came up unexpectedly on business, and I tagged along to do some shopping. Are you in a hurry? I suppose so. You men never lose a chance to awe us with the value of your time.” “No,” Harvey replied, “I'm not at all in a hurry.” “Good, then you can help me. I am buying a gown.” They went into Field's, and for nearly an hour Harvey “helped.” It did not take him long to realize that nowhere is a strong man more helpless than in a department store. He went through yards of samples, fingered dozens of fabrics; he discussed and suggested, all with a critical air that amused Miss Porter. She tried at first to take him seriously, but finally gave up, leaned against the counter and laughed. “Suppose we go up to the waiting room,” she said. “You can talk, anyway.” With a smile Harvey assented, and they seated themselves near the railing, where they could look down on the human kaleidoscope below.
