Sometimes Dick had other stories to tell. In his collegiate days, he had grown familiar with the typical slum and its problems. The class in sociology had visited such. So he went to the slums of St. Etienne, and behold, they were not slums at all, for the slum can not be grown, like a mushroom, in a night. It must have a thousand nauseous influences stagnating for a long time undisturbed. But here were meager little wooden huts, flanked by rusting piles of scrap-iron, or flats along the river-bottom where the high waters of spring were sure to send the dwellers in these shabby apologies for homes scrambling to the roofs, or drive them to the shelter of the neighboring brewery. Here as the waters swept under the stony arches of the bridges, old women tucked up their petticoats and fished for the richness with which a city befouls its river. Here they made themselves neat woodpiles of the drift of the sawmills, and turned an honest penny by exhibiting on their roofs gaudy advertisements of plug-tobacco, that those who passed on the bridge above might look down and read and resolve to avoid the brand thus obnoxiously glorified. Sometimes Dick had to relate a picturesque interview with a policeman who unfolded to him unknown phases of life, for though he believed in himself, Percival also believed in the other man, and therefore made him a friend. Every one likes a jolly friendly prince, and that was Dick's type. Or he would dip into a police court where all the stages of wretchedness were pitchforked into one another's evil-smelling company, so that it ranged from the highest circle of purgatory to the lowest depths of hell. "Why do you go to such places, Dick? It's nauseating," Madeline exclaimed. "Why?" he demanded. "I suppose that sometime, when I've made over my information into the neat systematic package that you prefer, I shall start a soul-uplifting row. I look forward to that as my career. You ought to get a career, Madeline." "A career? I know the verb, but not the noun," she retorted saucily. "I'm afraid mine is nothing but the trivial task, flavored with all the flavors I like best." Sometimes, when they went home together at night, Percival had stories to unfold to Norris alone--stories he could not tell Madeline, of things found in the mire, upon which the healthy happy world turns its back when every night it goes "up town" to pleasant hearthstones and to normal life. These were tales of foul sounds and foul air, where men and women gathered and drank and gambled and laughed with laughter that was like the grinning of skulls, hollow and despairing. They were stories of girls with sodden eyes and men with wooden faces--of innumerable schemes to suck money by any means but those of honor. And these were the phases of his study that Dick looked upon with a kind of anguished fascination, as more and more he saw how the hands stretched out of that mire smirched the city which he hoped to serve.
