Two different early checks for the Gould & Curry Mine. One is territorial, signed by Charles Bonner as supt. (who replaced Charles Strong). The other is 1865 and signed by Louis Janin as supt. Janin was a prominent mining engineer who was educated at the Freiburg School of Mines. Before coming to the Comstock, he worked for the Enriquita Quicksilver Mine near San Jose, California. He began his work on the Comstock at the Mexican Mill and sought to increase silver extraction that was being lost in the slimes and tailings. Using a modified Freiberg barrel amalgamation process, he was successful in profitably re-working the tailings at the Gould & Curry Mill. He was put in charge of the Gould & Curry Mine in 1866, when it was struggling.
