SAN DIEGO COUNTY. 715 When the desired thickness of salt has been deposited the pond isdrained and a crew of men is set to work to harvest the salt. Movabletracks are laid on the bottom of the pond and small dump cars, similarto ore cars, moved by gasoline locomotives, are used to receive the saltwhich is loaded by shoveling. From the pond where the salt is har-vested the loaded cars are transferred to a small electric railway whichruns along the crystallizing ponds, and thence go to the washing plant,where the salt is raised by a bucket conveyor and distributed into piles.

Here, as the salt ismoved along by a screw conveyor, it is washed by a current of saturatedbrine flowing in the opposite direction. From this washing trough, thesalt is raised by a conveyor having buckets made of wire mesh. Thest-successively pass under a stream of brine, which washes out any remnantof foreign matter which may be adhering to the salt. During the ascent,a final washing is given with a spray of fresh water. This conveyorraises the purified product to the top of a trestle about a hundred feethigh and discharges it into a long trough through w^hich, by screw con-veyors, it is transported to be dumped at convenient points in storagepiles to await the demand of the market. 716 GEOLOGY AND MINERAL RESOURCES.
