2 BULLETIN 948, U. S. DEPARTMENT OF AGRICULTURE. 
forth data showing as nearly as possible approximate oil and meal 
yields in each county of the cotton belt. These data are not nec- 
essarily conclusive, as the volume of information available for many 
counties is comparatively small. Moreover, even if complete in- 
formation as to yields were available, figures could not be laid 
down which would be absolutely accurate as to subsequent yields. 
It is believed, however, that the information given herein will be 
of material assistance to those who apply it with an understanding 
of general and local market conditions. 
SOURCES OF INFORMATION. 
Records of analyses of cotton seed made by company and com- 
mercial chemists during the five seasons 1914-15 to 1918-19, inclusive, 
were collected from the original analytical sheets by representatives 
of the Department of Agriculture. Data regarding 59,964 analyses 
were thus secured, but records of only 46,029 samples were used in 
this study, as in order to cover only prime seed records of samples 
showing marked damage or of samples collected prior to September 1 
and subsequent to January 31 are not included. The States of 
Georgia, South Carolina, and Alabama were the largest contributors 
of records of analyses, while some other States furnished compara- 
tively few records. 
As chemists make and report analyses of clean seed, an arbitrary 
allowance of 100 pounds of foreign matter and manufacturing loss 
per ton of seed has been made in presenting these data in order to 
approach as nearly as possible actual commercial conditions. This 
is the customary allowance made by chemists and is in line with 
losses reported by the Bureau of the Census, as shown in Table III, 
page 6. 
SEED PRODUCED AND CRUSHED, BY STATES. 
The quantity of seed produced differs materially from the quantity 
crushed in each State, because a considerable volume is retained on 
the farms and a considerable movement of seed for crushing from 
one State to another takes place each year. The quantity of seed 
crushed in each State during each year and the average for the five 
years, as compiled from records of the Bureau of the Census, are 
shown in Table I, page 5. Similar data showing the quantity of 
seed for crushing produced in each State are shown in Table II, 
page 5. As an illustration of the difference between the quantity 
of seed produced and the quantity crushed in a specific State, it is 
noted that in Tennessee an average of 123,000 tons was produced 
and an average of 264,000 tons was crushed. In Table III, page 6, 
are given the average total quantity of products and. the average 
manufacturing loss per ton of seed, and in Table IV, page 6, the
