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
