In due time they were rattling over a tangled maze of switches, dodging interminable processions of freight-cars, barely missing crowded passenger trains whose bells struck clear and then flatted as the trains flew by; defiling by narrow water-ways, crowded with small shipping; winding through streets lined with high, gloomy warehouses, amid the clang and clatter, the strangely-sounding bells and whistles of a thousand industries, each sending up its just contribution of black smoke to the pall that lay always spread above; and steaming at last into a great roomy shed where all was system, and where the big engine trembled and panted as if in relief at having run in safety a gantlet so hazardous. "Anyway, I'd rather live in Montana City than Chicago," ventured Mrs. Bines. "Whatever pride you may feel in your discernment, Mrs. Cadwallader, is amply justified," replied her son, performing before the amazed lady a bow that indicated the lowest depths of slavish deference. "I am now," he continued, "going out to pace the floor of this locomotive-boudoir for a few exhilarating breaths of smoke, and pretend to myself that I've got to live in Chicago for ever. A little discipline like that is salutary to keep one from forgetting the great blessing which a merciful Providence has conferred upon one." "I'll walk a bit with you," said his sister, donning her jacket and a cap. "Lest my remarks have seemed indeterminate, madam," sternly continued Percival at the door of the car, "permit me to add that if Chicago were heaven I should at once enter upon a life of crime. Do not affect to misunderstand me, I beg of you. I should leave no avenue of salvation open to my precious soul. I should incur no risk of being numbered among the saved. I should be _b-a-d_, and I should sit up nights to invent new ways of evil. If I had any leisure left from being as wicked as I could be, I should devote it to teaching those I loved how to become abandoned. I should doubtless issue a pamphlet, 'How to Merit Perdition Without a Master. Learn to be Wicked in your Own Home in Ten Lessons. Instructions Sent Securely Sealed from Observation. Thousands of Testimonials from the Most Accomplished Reprobates of the Day.' I trust Mrs. Llewellen Leffingwell-Thompson, that you will never again so far forget yourself as to utter that word 'Chicago' in my presence. If you feel that you must give way to the evil impulse, go off by yourself and utter the name behind the protection of closed doors--where this innocent girl cannot hear you. Come, sister. Otherwise I may behave in a manner to be regretted in my calmer moments. Let us leave the woman alone, now. Besides, I've got to go out and help the hands make up that New York train. You never can tell. Some horrible accident might happen to delay us here thirty minutes. Cheer up, ma; it's always darkest just before leaving Chicago, you know."
