do your self old time gold rocker box.

A rocker box (also known as a cradle) is a gold mining implement for separating alluvial placer gold from sand and gravel which was used in placer mining in the 19th century. It consists of a high-sided box, which is open on one end and on top, and was placed on rockers. The inside bottom of the box is lined with riffles and usually a carpet (called Miner's Moss) similar to a sluice.
The rocker box very much resembled the oldtime rocking cradle for infants, a commonplace object in any home in the 19th Century (and considerably earlier). The rocker box was especially useful in localities where limited water flow prevented the use of sluices and other techniques.
