Jacob Riis, How the Other Half Lives — Chapter III: The Mixed Crowd
“ The Irishman is the true cosmopolitan immigrant. All-pervading, he shares his lodging with perfect impartiality with the Italian, the Greek, and the "Dutchman," yielding only to sheer force of numbers, and objects equally to them all. A map of the city, colored to designate nationalities, would show more stripes than on the skin of a zebra, and more colors than any rainbow. The city on such a map would fall into two great halves, green for the Irish prevailing in the West Side tenement districts, and blue for the Germans on the East Side. ”
