The time wore on.

The noises in the streets became less frequent by degrees, until silence was scarcely broken save by the bells in church towers, marking the progress--softer and more stealthy while the city slumbered--of that Great Watcher with the hoary head, who never sleeps or rests.

In the brief interval of darkness and repose which feverish towns enjoy, all busy sounds were hushed; and those who awoke from dreams lay listening in their beds, and longed for dawn, and wished the dead of the night were past.
Into the street outside the jail's main wall, workmen came straggling at this solemn hour, in groups of two or three, and meeting in the centre, cast their tools upon the ground and spoke in whispers.

Others soon issued from the jail itself, bearing on their shoulders planks and beams: these materials being all brought forth, the rest bestirred themselves, and the dull sound of hammers began to echo through the stillness.
Here and there among this knot of labourers, one, with a lantern or a smoky link, stood by to light his fellows at their work; and by its doubtful aid, some might be dimly seen taking up the pavement of the road, while others held great upright posts, or fixed them in the holes thus made for their reception.

Some dragged slowly on, towards the rest, an empty cart, which they brought rumbling from the prison-yard; while others erected strong barriers across the street.
