At the same time the school children invaded the street, filling the air with a clamor of shrill voices, stopping at the stationers’ shops, or idling a moment in the doorways of the candy stores.  For over half an hour they held possession of the sidewalks, then suddenly disappeared, leaving behind one or two stragglers who hurried along with great strides of their little thin legs, very anxious and preoccupied.

Towards eleven o’clock the ladies from the great avenue a block above Polk Street made their appearance, promenading the sidewalks leisurely, deliberately.  They were at their morning’s marketing.  They were handsome women, beautifully dressed.  They knew by name their butchers and grocers and vegetable men.  From his window McTeague saw them in front of the stalls, gloved and veiled and daintily shod, the subservient provision men at their elbows, scribbling hastily in the order books.  They all seemed to know one another, these grand ladies from the fashionable avenue.  Meetings took place here and there; a conversation was begun; others arrived; groups were formed; little impromptu receptions were held before the chopping blocks of butchers’ stalls, or on the sidewalk, around boxes of berries and fruit.

From noon to evening the population of the street was of a mixed character.  The street was busiest at that time; a vast and prolonged murmur arose—­the mingled shuffling of feet, the rattle of wheels, the heavy trundling of cable cars.  At four o’clock the school children once more swarmed the sidewalks, again disappearing with surprising suddenness.  At six the great homeward march commenced; the cars were crowded, the laborers thronged the sidewalks, the newsboys chanted the evening papers.  Then all at once the street fell quiet; hardly a soul was in sight; the sidewalks were deserted.  It was supper hour.  Evening began; and one by one a multitude of lights, from the demoniac glare of the druggists’ windows to the dazzling blue whiteness of the electric globes, grew thick from street corner to street corner.  Once more the street was crowded.  Now there was no thought but for amusement.  The cable cars were loaded with theatre-goers—­men in high hats and young girls in furred opera cloaks.  On the sidewalks were groups and couples—­the plumbers’ apprentices, the girls of the ribbon counters, the little families that lived on the second stories over their shops, the dressmakers, the small doctors, the harness-makers—­all the various inhabitants of the street were abroad, strolling idly from shop window to shop window, taking the air after the day’s work.  Groups of girls collected on the corners, talking and laughing very loud, making remarks upon the young men that passed them.  The tamale men appeared.  A band of Salvationists began to sing before a saloon.

Then, little by little, Polk Street dropped back to solitude.  Eleven o’clock struck from the power-house clock.  Lights were extinguished.  At one o’clock the cable stopped, leaving an abrupt silence in the air.  All at once it seemed very still.  The ugly noises were the occasional footfalls of a policeman and the persistent calling of ducks and geese in the closed market.  The street was asleep.
