gallons, or 60,000 pounds, is considered a carload unless otherwise 
specified. For all practical purposes, a gallon of peanut oil can be 
considered as weighing 1 Y A pounds. Occasionally small lots of 
crude peanut oil are shipped in iron-bound barrels or drums holding 
about 400 pounds net. 
YIELDS OF PEANUT OIL 
The quantity of peanut oil obtained from a ton of crushing stock 
depends upon the variety, the quantity of trash in the lot, the mois- 
ture content, and, primarily, upon whether it is straight farmers' 
goods or so-called "mill stock" or "oil stock.'' In 1922 and 1923 
the bulk of the peanut crushing in the Southeast, which turns out 
Fig. 36.— Hydraulic presses used for crushing oil from peanuts 
most of the crude peanut oil made in the United States, was from 
mill stock, or No. 3 peanuts. This includes shelled peanuts picked 
out by the operators at the belts in the shelling plants as behig 
below grade, broken pieces of nuts, and undersized kernels which 
passed through the screens during the shelling operations. Crushers 
figure that No. 3 Spanish peanuts should turn out about 700 pounds 
of prime crude peanut oil and 1,200 pounds of peanut cake or meal, 
allowing 100 pounds of manufacturing loss per ton of mill stock, 
chiefly in the form of moisture. In commercial practice, Spanish 
and Kunner mill stock are usually not kept separate, but are crushed 
together. 
According to southern crushers, a ton of farmers' stock Spanish 
peanuts yields, if shelled before crashing, about 575-600 pounds of 
prime crude oil and about 770 to 800 pounds of cake of about 46 
per cent protein content. If crushed straight, with shells, a ton of
