Summary and Conclusions A Bauer Mill officially approved by the A.O.C.S. for grinding samples of soybeans to be used for oil determinations was used to grind duplicate series of the 10 check samples of soybeans sent out each year by the Smalley Foundation Committee. When the mill was operated at high temperature and forced to grind at its maximum rate, the 10 samples averaged 18.03% of oil. A duplicate series of 10 samples ground in a water‐cooled mill at about one‐half the maximum possible rate of grinding for the mill averaged 17.57% oil. Improper operation of a Bauer Mill when preparing soybean seed samples for analysis can cause abnormally high oil percentages. A simple mechanical device to reduce the rate of feed is suggested for use with the mill. A Bauer Mill is satisfactory for use in grinding samples of soybeans for oil analysis when it is properly operated.
