The form of the mashing apparatus and the tem- peratures at which the several operations are conducted are modified as may be necessary to fit the peculiarities of the raw materials. In this country maize is the chief starchy material used in the manufac- ture of alcohol. It is mashed in a sort of kettle known as a vacuum cooker. The vacuum cooker is a horizontally placed cylindrical vessel made of steel holier plate, and has a capacity of about 40 gallons for every bushel of grain to be mashed in one charge. Just below the center of each end it is provided with stuffing boxes, through which a shaft passes. The latter carries several rakes or stirring arms inside the shell; outside it is provided with a strong toothed wheel, arranged for chain drive. Thermometers and try cocks are mounted in each end of the shell, and if the cooker is large a third thermometer is set in the middle of the side. In a row along the bottom are several small steam-inlet valves so constructed that while steam can pass freely into the cooker the contents of the latter can not run back into the steam pipe when pressure is removed outside. At the middle of the top of the cooker is a dome fitted with a pipe connection which leads to a "; From one side of the latter connection is made to the steam supply, which must be carried at about 50 pounds pressure; from the other side connection is made with the vacuum pump, and from the top a pipe leads to a blow-off valve. On top of the cooker, at one end, there is a manhole through which water and meal may be introduced, and in the bottom, at one end, there is a discharge valve which opens into a pipe leading to th
