Baker and Hamilton purchased the Pacific Mail
Dock and plant in 1879 and brought the Sweepstake Plow Company to
Benicia and opened the Benicia Agricultural Works. The plows became
famous and the plant employed about 400 workers manufacturing plows,
wagons, farm implements, mowers and harvesters. In 1914 it sold out to
Yuba Manufacturing which also made farm equipment but was more famous
for its gold dredges.
