BILLY BYRNE was a product of the streets and alleys of Chicago's great West Side. From Halsted to Robey, and from Grand Avenue to Lake Street there was scarce a bartender whom Billy knew t by his first name. And, in proportion to their number which was considerably less, he knew the patrolmen and plain clothes men equally as well, but t so pleasantly. His kindergarten education had commenced in an alley back of a feed-store. Here a gang of older boys and men were wont to congregate at such times as they had naught else to occupy their time, and as the bridewell was the only place in which they ever held a job for more than a day or two, they had considerable time to devote to congregating. They were pickpockets and second-story men, made and in the making, and all were muckers, ready to insult the first woman who passed, or pick a quarrel with any stranger who did t appear too burly. By night they plied their real vocations. By day they sat in the alley behind the feedstore and drank beer from a battered tin pail. The question of labor involved in transporting the pail, empty, to the saloon across the street, and returning it, full, to the alley back of the feed-store was solved by the presence of admiring and envious little boys of the neighborhood who hung, wide-eyed and thrilled, about these heroes of their childish lives.
