The pollution boys were away smelling factory smoke in Gloucester: A gum factory.'

There was no factory smoke or dust to mar it, and it lay in great unbroken sheets.

The very air is not good enough for them: there is too much factory smoke in it.

Don't the men in your factory smoke?

A stretch of wooded hills lay before them, shrouded in trailers of mist that hung across the trees like factory smoke.

Ledford stepped from the factory smoking his own cigarette.
