A California single bucket gold dredger. By means of this machine the bottom of the river is dug up and delivered into a sluice whence the sand is separated and washed on gold-saving tables and the waste material is conveyed away by an endless carrier. The dredger Indiana provided with a conveyor and an auxiliary sand pump.
