When sending the clinker to the storage 306 MINES AND MINERAL RESOURCES. pile in place of the ball mills, instead of going to the rotary coolers it isput through cooling towers similar to those described in the plant ofthe Standard Portland Cement Company at Napa Junction (see underNapa County). Gypsum, 2 to 2^ per cent, is added to the clinker beforegrinding. The tube mills designedly do not grind the product in asingle stage to its desired ultimate fineness. The discharge goes to anEmerick Air Separator. This consists of a series of horizontalrevolving discs, from which the fines are drawn up by suction to thestock house, and the coarse particles which work to the periphery ofthe discs are returned to the Photo No. 76. Concrete Bridge at Vacaville, Solano County (1911). In the stock house automatic sacking machines are used and a beltconveyor takes the filled sacks of Golden Gate Brand cement to thewaiting railroad cars alongside. The Solano County jail at Fairfield(see photo No. 72) is of reinforced concrete, in which Golden Gatecement was used. The Cement, ToJenas and Tidewater Railroad, ownedby the company, connects Cement with Tolenas Station on the mainline of the Southern Pacific, 2 miles to the south. A large and well equipped laboratory is maintained for chemicalanalyses and physical testing. It is supplied with natural gas fromthe well of the Rochester Oil Company, 5 miles southeast of in the equipment of the two mills are 250 electric motors,varying from 580 down to 1 , and there are eight 6x 60,eleven 7 x 80, and one 8 x 100 rotary
