interesting that although noirture excesses were nigh and were found 
in a large percentage of the lots of seed that were graded, relative- 
ly little deterioration in the oil -/as found, probably owing to the 
coolness of the harvest season. This is in contrast to the season of 
1937-33 when, with little or no excess seed moisture, hut with com- 
binations of high atnospheric temperatures and humidity during the 
harvest season, serious deterioration occurred in the oil. 
Second Amendment to Standard Grades 
The cottonseed marketed in the Mississippi Valley States dur- 
ing the season of 1937-38 was of the poorest quality or. record. The 
intensity of the deterioration contrasted with that of the previous 
season, however, in that it was most severe in Louisiana and contigu- 
ous counties in Mississippi and le^..st severe in Tennessee, The con- 
tinued rains and the warm, hunid weather during the harvest period 
made it practically impossible to prevent spoilage. Many lots of cot- 
tonseed were so badly decomposed when offered for sale to the oil 
mills, that it was not possible to process thorn. In many instances it 
was found that when these seed were graded according to the official 
standards, the grades were no longer time indexes of relative value. 
Since this contingency had not been anticipated when the standards 
were established, the standards were again amended on Juno 7, 1938, by 
providing that all cottonseed which, upon analysis, were found so low 
in quality as to result in a grade below 25, should not be graded on 
the standards but be left the subject of negotiation (appendix C), In 
the early part of the 1937-38 season the industry had recognized that 
grade 25 was the minimum that represented fair relative values and by 
universal consent had adopted this modification in applying the 
standards. 
Analyses Reported to Department of Agriculture 
Immediately after the establishment of the standards, in 1932, 
arrangements had been made by the Department of Agriculture with all 
chemists, both commercial and private, whereby a copy cf each cotton- 
seed analysis and grade report, when made according to the official 
standards, would be furnished the Department for its study. 
Beginning with the season of l934-:-5, fairly complete records 
have been kont of the factors of grade cf the cottonseed produced in 
Arkansas, Louisiana, Mississippi, and Tennessee, In most instances 
these data are available for each cotton-producing county in these 
States; but in this report, the data ^re given on a State-wide basis 
for the seasons of 1934-35, 1935-35, 1936-37, and 1937-33 (tables 1, 2, 
3, and 4), In addition to the grade reports considered in these tables, 
other reports were received, giving the analysis and grade of seed be- 
lieved to have been grown in Arkansas, Missouri, Illinois, Kentucky, or
