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.

"A spiral turbine , also known as a closed turbine , is a water turbine with an inlet spiral. The opposite is the shaft turbine , also known as an open turbine or chamber turbine , in which the water is not guided in any particular way before entering the guide vane ring. Spiral turbines are now the usual design for Francis and Kaplan turbines . They are more efficient than shaft turbines. Shaft turbines are now mostly found only in historic power plants and small hydroelectric power plants with low heads."
