During the 1950s, Dr. Jacob Paz grew up in an agricultural environment in Israel where he attended a very famous high school in Israel called Kadoorie where Yitzhak Rabin was a student. After his graduation, Jacob joined the Israeli army building his skills so that he could get into technical school after he fulfilled his army service. For two years he attended technical school and then started working for the Israel Atomic Energy Commission in Dimona, Israel making atomic bombs in the 1960’s. After working in Dimona, Jacob was accepted into UC Davis and moved to the United States to study veterinary medicine. After one semester, he realized that he preferred history and left California for New York City, There he earned degrees in Jewish history and chemistry from the Jewish Theological Seminary. He quickly moved onto graduate school and earned his master’s degree in marine science and environment from CW Post, Long Island University in Greenvale, New York. In 1972, he returned to I

The hopper on the starboard side of the dredge is visible. The dredge processed the gravel through jigs as opposed to sluices. With the volume of material the dredge handled, a sluice would have been impractical. A jig has a diaphragm driven by an electric motor which pulsates. The Yuba jigs were about 42 inches long by 42 inches across. A bed in the jig was filled with steel shot. As the gravel material floated across the steel shot, the jig's pulsating diaphragm raised the steel shot-bed up and gold, being so much heavier than the gravel and the steel shot, would work its way down through the shot-bed. The jig bed usually has a 1/8-inch mesh stainless steel screen so that any gold finer than 1/8 inch will pass through the screen. The jig pulsated between 60 and 100 times a minute, a "steady throb." Gold coarser than 1/8 inch, being very heavy, would be held on top the screen beneath the bed of steel shot.
