Of the pushing, jostling, clamoring mob, which the sidewalks are much too narrow to contain, observe the preponderance of girls.

From factory, office, and department store they come, thousands and tens of thousands of girls.

Above the roar of the elevated, the harsh clang of the electric cars, the clatter of drays and wagons, the shouting of hucksters, the laughter and oaths of men, their voices float, a shrill, triumphant treble in the orchestra of toil.
You may get another vivid, yet subtle, realization of the interdependence of women and modern industry if you manage to penetrate into the operating-room of a telephone exchange.

Any hour will do.

Any day in the week.
