average yields of oil and meal, as compiled from records of the 
Bureau of the Census. 
YIELDS OF OIL AND MEAL, BY STATES AND COUNTIES. 
The yields of oil and meal in each State and in the United States 
during each year, also the five-year average yields, as compiled from 
the records of analyses, are shown in Table V, page 7. Yields by 
States shown by these analyses are very close to actual yields, as 
reported by oil millers to the Bureau of the Census. It should be 
remembered that information based on analyses applies to seed pro- 
duced within each State, whereas the information based on actual 
yields applies to seed crushed within each State, which amounts 
have been shown to vary considerably. Also, information given in 
Table V is based on meal with a theoretical ammonia content 
of 8 per cent in Texas and Oklahoma and 7 per cent in all other 
States, whereas that reported in Table IV is based on the actual 
meal produced at the mills, regardless of composition. This close 
agreement between the data from the two different sources is in- 
teresting in that it indicates the reliability of the analyses and the 
data presented in Tables V, page 7, to VIII, page 209, inclusive. 
However, as previously pointed out, the yields for individual coun- 
ties as presented in Table VI, page 8, in some instances probably 
are not representative, on account of the small number of records, or 
other conditions beyond control of the investigation. The maps 
of the different States on pages 211 to 221 show the average yields of 
oil per ton of seed by counties in ranges of 15 pounds. 
YIELDS OF OIL AND MEAL, BY MONTHS. 
Qualities of seed vary as the season advances. Early seed usually 
has a greater moisture and smaller oil content, and late seed is 
usually affected adversely by weather conditions. Table VII, page 202, 
shows the monthly variation of oil and meal yields for each of the 
five years and an average for the period for the United States and 
for individual States. As only the five months, September to Janu- 
ary, inclusive, are shown, the variations do not appear so great as 
they would were the entire season represented. 
VARIATION OF YIELDS OF OIL AND MEAL ON SAME MARKET. 
In Table VIII, page 209, data are presented which show a few 
selected examples of variations in oil and meal yields in the same 
market on the same day. It will be noted that with seed grown under 
conditions which may appear similar to the seller and buyer, a con- 
siderable difference in intrinsic value sometimes exists. A deter- 
mination of such differences is, of course, impossible in most instances 
without a chemical analysis of the seed at the time of sale. Under
