And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

coal dust used to fire the boiler. Not coal dust in the air. When the engine is worked hard, the draft pulls the coal dust off the grate and through the boiler.
