The meal is thenpressed in scourtins made of horse hair, a pressureof 3,850 .pounds to the square inch being exerted andleft on for an hour, which is suflBcient to extract allthat can be obtained in the first yield. The meal isthen removed from the scourtins, ground a secondtime, heated to a temperature of about 70° C. (158° F.),. DIAGBAH OF THE FBODVCTION OF FIVE VIEWS OFBY MTJLTIFHOTOGBAFHY. Peanut Oil. The report of the American consul atMarseilles contains some facts concerningthe manufacture of peanut oil, which is largely coming into use for various economic purposes.

The general method of producing the oil is as fol-lows : On arriving at the factory the peanuts are firstplaced in a machine of the nature of a winnower, inwhich all outside dirt and other foreign substances are If oil of a very finequality is required, the nuts are crushed only once,partially ground nuts yielding a smaller but finer pro-duct.
