1. Working in the Salt Ponds Marker
WHEN THE PONDS AROUND YOU were first built, producing salt by solar evaporation required intense labor and a lot of time. Workers had to move seawater from San Francisco Bay (only 2.5% salt content) through a series of evaporation ponds to concentrate the salt to the point of crystallization. This sea water to salt process took almost five years.
IN THE LATE 1800s laborers used shovels,wheelbarrows, and carts to move the crystalized salt out of the evaporation ponds. In later years mechanized equipment and narrow-gauge railways helped speed up the harvesting process.
Would you work for less than $1.35 a day?
In 1901 Japanese immigrants made up most of the Oliver Salt Company's
harvest time employees. Segregated treatment, harsh working conditions and the
Company's reluctance to raise wages to $1.35 a day (around $3 an hour today)
led many of these workers to find higher paid employment in agriculture.
