They were rough boxes mounted on rockers, of which the one at the forward end was a little lower than the other, so as to give the cradle a slight slope in that direction. Each had an iron grating placed across its upper end, and a few wooden cleats nailed crosswise of its bottom. A hole was cut in its foot-board, and a handle, by means of which it was rocked, was fastened to its head-board. There were two men to each cradle: one to shovel dirt on to its grating, and the other to rock it and pour water over this dirt to wash it through. The grating was so fine that only the smallest pebbles could pass through it. As the dirt and water fell to the bottom of the cradle, and ran through it to the opening in the foot-board, the fine particles of gold sank, of their own weight, and lodged against the cleats. From these it was carefully gathered several times each day by the white overseer who had charge of the diggings, and sent to Fort Garland for safe-keeping.
