GRUB THE GROUND FOR CRYSTALS" From their Roman conquerors the ancient Bretons learned how to obtain salt from sea water in the 3,700-acre marshes atBatz, near Le Croisic. Lying about six feet below high-water mark, the rectangular reservoirs are flooded at spring tides. When the water evaporates, workers gather the crystals and pack them inbags to be shipped. Coasting vessels from the north bring wine and wood in exchange for salt. Many of the marsh mengotosea during the fishing season.
