A Ten Years' War: An Account of the Battle with the Slum in New York — Story, Setting & Ideas

The Tenement as Physical and Social Trap

Riis devotes two chapters to the tenement itself, treating it as both a building problem and a moral one. He cites the Tenement House Committee’s finding that 324,000 persons lived without sight of any green spot, and that buildings sometimes occupied ninety-three percent of a block. The language is precise: sunlight “never entered” such homes; darkness and dirt were the tenant’s inheritance. The tenement’s worst mischief, Riis argues, was smothering the instinct for solitude and depth—the soil of character—and replacing it with the instinct for the crowd. This is not metaphor but structural analysis: the physical crowding produces a psychological flattening that makes the street’s surface logic inevitable.

The Street Boy as Product and Symptom

The chapter “The Genesis of the Gang” uses Jacob Beresheim as a type. Born in a tenement, Jacob inherits no sunlight, only darkness and dirt. The street teaches gambling first, stealing second; the two are “never far apart.” Riis notes the comic detail of a German grocer baffled by the cry “cheese it,” but the tone is grim. The school system, he charges, produced “queer manikins stuffed with information for which they have no use,” and a “hopeless slurring of tasks” that left no moral sense. Jacob did not even attend school; the truant law was a dead letter for twenty-five years. Riis limits his inference to what the excerpts show: the boy drifted from age twelve onward, and the system offered no census, no alternative to jail.

Movement Between Diagnosis and Prescription

The book’s structure alternates between exposing conditions and proposing remedies. After chapters on the tenement blight and its cure, Riis turns to the tenant, then to the gang, then to “Letting in the Light” and “Justice for the Boy.” This movement mirrors his argument that reform must address both physical environment and human development. The illustrations—police station lodging rooms, model tenements, Mulberry Bend Park, a rooftop playground—reinforce the shift from problem to solution. Riis does not claim the battle is won; the closing chapters on “Reform by Humane Touch” suggest ongoing struggle. The reader is positioned as a witness to a campaign still in progress.

Recurring Images of Light, Dirt, and the Crowd

Riis returns repeatedly to light as a measure of decency. Sunlight “never entered” Jacob’s home; later chapters promise “Letting in the Light.” Dirt is both literal and symbolic: the street boy takes to dirt as his “natural weapon,” and it is said to be the only friend that stuck to him. The crowd is the tenement’s legacy—an instinct that replaces individual character. These images form a consistent vocabulary: darkness, dirt, and the crowd are the slum’s trinity; light, cleanliness, and solitude are the reformers’ tools. Riis’s prose is plain but pointed, avoiding sentimentality. He reports the German grocer’s confusion without mockery, and the statistic of ninety-three percent coverage without hyperbole.

Readers should attend to how Riis uses the individual case—Jacob Beresheim, the German grocer, the Tammany-swept street—to ground his broader arguments. The book is not a continuous narrative but a series of strategic forays, each chapter building a case for a specific reform. The illustrations are integral, not decorative: they show the physical spaces Riis wants to change. Approach the text as a reformer’s brief, shaped by a decade of observation and advocacy, and notice how the structure itself argues that environment determines character—and that environment can be remade.

Sometimes I think back on Riis’s stories—young Jacob Beresheim caught in a system that had already given up on him—and feel that strange ache of near-missed justice. We look for it in the old photographs too. There’s a quieter companion piece, Ragged homes and how to mend them — Inside the Classic, that traces that same longing for light through doorways we can almost step through. Just an echo, somehow.
