Reef drive

Definition of reef drive

A drive cut or constructed entirely through the bed-rock, and either above or below the level of the gutter, or along the face of the reef, or partly in the reef. Reef-drives are usually cut for the purpose of seeking the gutter, or seeking reef-washes, or working out reef-washes, or as air drives for ventilation. – The Gold Fields and Mineral Districts of Victoria, 1869.
