From the liquid which runs out first is made the very finest oil, known as "virgin ; The pres- sure is then increased very gradually until the full power of the machine is reached. This presses out the second quality of oil, which is generally mixed with the first. After obtaining all the oil possible by the first pressure the '"cheese" is taken out, thoroughly broken up in hot water, and again pressed. This yields the third quality, which is very much inferior to the first and second. Some- times the "cheese" from the first pressing is thoroughly broken up with cold water and pressed again before being treated with hot water. In this way a little oil is obtained that differs little from the second quality, and iiia\' be mixed with it.

Much of the foreign matter quickly separates, the oil appearing on the top. The oil is removed to other receptacles in which it can stand from two to five months for perfect separa- tion of undesirable sediment. These settling tanks may be made of well-tinned metal, or of cement lined with glass or other imper- vious substance. The first settling is con- veniently made by means of a
