Rocker, probably invented by Cornish miners, was one of the tools used to easily extract gold from rocks and riverbeds during the California Gold Rush. Isaac Humphrey, generally known as Major is said to have introduced the rocker to the California gold fields. In regular mining work the rocker is cleaned up after every 2 or 3 hours, or oftener when rich ground is worked, if gold begins to show on the apron or in the riffles. In cleaning up after a run, water is poured through while the washer is gently rocked; the top sand and dirt are washed away.
