Business owners and residents boarded up windows and cleared away debris today as Ferguson sought a return to normal after three nights of unrest.
The trouble was sparked by a grand jury decision's not to indict a police officer over the shooting death of an unarmed black 18-year-old.
Protesters continued to hold scattered demonstrations, including a group that rushed into City Hall in St Louis, the city neighbouring Ferguson, screaming "Shame, shame".
Police locked down the building and called in more than a hundred extra officers. Three people were arrested.
About 200 demonstrators marched through central St Louis and held a mock trial of Darren Wilson, the white police officer who shot and killed Michael Brown during an August 9 struggle.
Since the grand jury's decision was announced on Monday night, protesters in cities throughout the country have rallied behind the refrain "hands up, don't shoot," and drawn attention to other police killings.
In New York City yesterday, Mr Brown's parents joined the families of two other black men who were unarmed when they died at the hands of police.
The families joined arms with civil rights leader Al Sharpton and prayed for justice at the Harlem headquarters of Mr Sharpton's organisation, the National Action Network.
As the tension in Ferguson eased somewhat, Mr Wilson broke his long public silence, insisting on national television that he could not have done anything differently in the August 9 confrontation.
Tensions in Ferguson, at least on the surface, had diminished considerably by last night.
A few dozen protesters huddled in falling snow outside police headquarters after dark, in contrast to the hundreds who took to the streets on Monday in a night of arson, looting, sporadic gunfire and clashes with police that ended in more than 60 arrests.
Another 45 protesters were taken into custody in smaller, more isolated bursts of lawlessness that erupted on Tuesday night. Many residents hoped that the relative calm would last today.
"This is my Ferguson, you know?" said Kari Hobbs, 28, as she watched 17-year-old Molly Rogers paint "Love Will Win" in bright pink on a board that covered a smashed window at Cathy's Kitchen, a restaurant not far from the Ferguson Police Department.
