The complexion changes at dinnertime, when the excursionists and suburbanites, disgorged by the train-loads from subway kiosks, take over.

The rush reaches its peak between 8 and 8:30, when the steady but slow-moving stream of stragglers, strollers and starers meets the head-on rush of theatre-bound hordes.

Again at 11, when the curtains fall in three dozen houses, there is a mad scramble of hemmed-in humanity.

Soon after midnight, though the lights still blink bravely, the crowd thins out and drops off. Broadway, having lost most of the places that attract revelers, is no longer a late street.

Its larger night clubs, patronized more by tourists and middle-class burghers, have little play after 2 A.M. Only a few even bother to present late shows, though in other sections of the city floor entertainment runs until 4 o'clock.

When the gawkers get off the Stem—but long before the break of day—it is taken over by its third set of citizens.

Dope-peddlers work the west side of the street, between 45th and 47th Streets, and on Seventh Avenue, between 48th and 50th Streets, on the east side of the street.

You can buy reefers in a dozen cheap bars on 48th between Sixth and Seventh Avenues, and at 51st and Seventh, in front of the cafeteria. In fact, when Federal agents haven't their full quota of pinches in at the end of the month, they tap people at random here—and almost every one has the "makings."

Blowzy hookers congregate at 47th.
