than from wet-process germs, because the same quantity of materia] 
yields much less oil over which to distribute an equivalent operating 
cost. 
In an effort to determine as nearly as possible the actual cost of 
producing corn oil, based on the cost of equipment and of operating 
the same, the figures in Table II are submitted. The cost of the 
equipment is, of course, an estimate based on present-day prices. 
The cost of repairs on expellers and the items of labor, power, and 
productive capacity were obtained from a careful study of the 
operation of a 4-expeller unit in a typical hominy plant.

Production.—Per machine, 3,000 pounds of oil in 24 hours, 12,000 pounds: Cost per 
pound ($118.89--12,000), 0.99 cents. 
These figures are intended to show approximately what it costs 
to expel corn oil in connection with hominy plants where the neces- 
sary floor space may be arranged for without the construction 
of an additional building. Overhead charges, such as management 
and selling organization, are not included. It seems probable that 
the installation of an expelling plant such as is here outlined would 
not necessitate any material addition to the pay roll except for the 
labor required to operate the machines. Although in making an 
actual cost accounting the charge for overhead expense should be 
included, the amount thus chargeable would be so difficult to ascer- 
tain, owing to the fact that the expelling is so involved in the other 
operations of the plant, that to include it here would be largely guess- 
work. It is evident that if an independent plant were operated 
exclusively for the expelling of corn oil the heavy overhead expense —
