Churning with an Elastic Rod.

—The old-fashioned churn is set in motion by the aid of another kind of power, as seen in [Fig. 102]. A long, tough, flexible stick is fastened into the cross-beam in the ceiling, so that its larger end is held firm by two iron clasps. The elasticity of the rod is such that, when the smaller end is drawn down by hand, which, at the same time, moves the dasher, it rebounds, and thus saves considerable expenditure of power.
