During his three years of probation, my father had made a number of false starts in business. His history for that period is the history of thousands who come to America, like him, with pockets empty, hands untrained to the use of tools, minds cramped by centuries of repression in their native land. Dozens of these men pass under your eyes every day, my American friend, too absorbed in their honest affairs to notice the looks of suspicion which you cast at them, the repugnance with which you shrink from their touch. You see them shuffle from door to door with a basket of spools and buttons, or bending over the sizzling irons in a basement tailor shop, or rummaging in your ash can, or moving a pushcart from curb to curb, at the command of the burly policeman. "The Jew peddler!" you say, and dismiss him from your premises and from your thoughts, never dreaming that the sordid drama of his days may have a moral that concerns you. What if the creature with the untidy beard carries in his bosom his citizenship papers? What if the cross-legged tailor is supporting a boy in college who is one day going to mend your state constitution for you? What if the ragpicker's daughters are hastening over the ocean to teach your children in the public schools? Think, every time you pass the greasy alien on the street, that he was born thousands of years before the oldest native American; and he may have something to communicate to you, when you two shall have learned a common language. Remember that his very physiognomy is a cipher the key to which it behooves you to search for most diligently. * * * * * By the time we joined my father, he had surveyed many avenues of approach toward the coveted citadel of fortune. One of these, heretofore untried, he now proposed to essay, armed with new courage, and cheered on by the presence of his family. In partnership with an energetic little man who had an English chapter in his history, he prepared to set up a refreshment booth on Crescent Beach. But while he was completing arrangements at the beach, we remained in town, where we enjoyed the educational advantages of a thickly populated neighborhood; namely, Wall Street, in the West End of Boston. Anybody who knows Boston knows that the West and North Ends are the wrong ends of that city. They form the tenement district, or, in the newer phrase, the slums of Boston. Anybody who is acquainted with the slums of any American metropolis knows that that is the quarter where poor immigrants foregather, to live, for the most part, as unkempt, half-washed, toiling, unaspiring foreigners; pitiful in the eyes of social missionaries, the despair of boards of health, the hope of ward politicians, the touchstone of American democracy. The well-versed metropolitan knows the slums as a sort of house of detention for poor aliens, where they live on probation till they can show a certificate of good citizenship.
