Tennessee, but these data were so incomplete with respect to point of 
origin of the seed in question, that it was thought "best to on it then 
fron the tables. There were 900 of these reports for 1S34-35, nore 
than 1,800 reports for 1935-36, and 787 reports for 1936-37, All 
reports for the season of 1937-38 contained the identification of the 
State and county in which the seed were produced, A tabulation of the 
onitted data fron these reports has been nade, but they are not in- 
cluded herewith, since it was found that they would nake no naterial 
change in the results as given. 
Although the seasonal variations and the averages of the grades 
are of interest for general comparisons, it is believed that, fron the 
producer's standpoint the distribution of the grades are of even 
greater interest. Such data are extended in tables 5, 6, 7, and 8; 
but, since the bulk of the graded lots was classified between grade 80 
and grade 120, all lots falling below 80 in grade are grouped. Pro- 
ducers should be particularly interested in the evidence that, in 
spite of seasonal difficulties that result in reducing the general 
quality of the cottonseed, a large nunber of shipments sold each nonth 
of each season had been sr> carefully harvested and handled as to be 
classified in the preniun grades, 
For the information of those. who nay wish to estimate the 
quantity of cottonseed covered by these reports, it nay be said that 
each sample presumably represents an average carlo t or its equivalent; 
that is to say, approximately 25 tons of cottonseed* 
Explanation of Tables 
In brief explanation of the tables, it nay be pointed out that 
the yields of oil and cake given are the expected yields under stand- 
ard^m^nu^acturing efficiency. Actual yields, therefore, may be slightly 
^lightly less than the figures given in the tables; but the averages 
are believed to be fairly close to the actual averages. 
Referring to table 1, it will be seen, for example, that in 
Arkansas 305 lots of cottonseed were sampled and graded during the 
month of August 1934, The oil content varied from 14.2 percent to 21,1 
percent and averaged 17,65 percent. The yields of til varied from 224 
pounds to 366 pounds and averaged 294 pounds per ton of seed. The am- 
monia varied from 3.04 percent to 4,48 percent and averaged 3,77 per- 
cent which when converted into protein represented 15.63 percent, 23,03 
percent, and 19,38 percent protein respectively. From these ammonia 
contents it is possible to produce .cake of 41,13 percent protein con- 
tent, ranging from 714.1 pounds to 1052,8 pounds and averaging 885,9 
pounds per ton of seed. According to the official standards, the 
quantity index varied from 82.2 to 109,5 and averaged 98,22. The 
quality index of 148 lots was lowered for Cause. These were divided 
as to cause as follows: 7 lots were found to contain excesses of free
