Not illustrated. 1904 edition. Excerpt: ... light-straw color. The pressing of the oil in connection with its refinement may be done at a summer temperature, but in that case only a portion of the foots are extracted and the oil has a poor weather-test. The usual Weather pressing during the summer yields 5 per cent of foots, and the oil stands a temperature of about 50 F. If pressed at a temperature of 32 to 35 F., the foots extracted represent about 10 per cent of the original bulk. The foots are used as a substitute for tallow in leathercurrying and also in soap-making, the market price approximating 3 cents per pound. The products from refining menhaden oil are pressed extra light, pressed light, pressed light brown, pressed dark brown, bleached, extra bleached, oil foots or pressings, bleached oil foots, extra bleached oil-foots, and menhaden oil soap. The first four grades of pressed oil are obtained respectively from A, B, C, and D grades of crude oil. A difference of about 1 cent per gallon exists between the prices of each of these consecutive grades of pressed oil. The pressed light is the standard grade, and when that sells at 30 cents per gallon the pressed extra light sells at 31 cents, the pressed light brown at 29 and the pressed dark brown at 28 cents per gallon. On the same basis the bleached sells at 33 cents per gallon, the extra bleached at 35 cents; and the same oils pressed at a low temperature sell for 1 or 2 cents more per gallon. A corresponding price for the unbleached foots is 2-cents per pound; bleached foots, 31 cents per pound; extra bleached foots, 4 cents, and menhaden-oil soap, 4 cents. The names " straits oil" and " bank oil" were formerly applied to certain grades of cod oil, but at present these refer, respectively, to more
