Supreme Court of New Hampshire December 6, 1932 (York v. Clow)

Marble, J.

The defendant, who owned and operated a sawmill in Wolfeboro, employed the plaintiff, an independent contractor, to repair the safety-valve of a steam-boiler located in the mill. The blow-off or waste-pipe ran from the safety-valve out through the south wall of the boiler-room about nine feet from the ground.
