DELISTING AND RECLEANING COTTONSEED FOR PLANTING. 19 
little linters or fuzz is left on the seeds and greater benefit is derived 
from the operation both as to duration required for germination and 
as to efficiency in recleaning. 
Delinting greatly accelerates the germination of cottonseeds. 
Under ideal conditions of moisture and temperature a full germina- 
tion may be obtained with delinted seeds in two days less time than 
with ginned seeds, while under conditions of a deficiency of moisture 
the difference in duration in favor of the delinted seed is much greater. 
Delinting reduces the weight of the individual seeds, thus increasing 
the number of seeds and consequent planting capacity of delinted 
seeds per unit of weight. For example, 161 pounds of linters removed 
per ton of seed reduces the weight of the individual seeds 8.05 per 
cent and a ton of such delinted seed would contain 8.75 per cent 
more seeds and have a correspondingly greater planting capacity. 
Delinting reduces the volume of cottonseed per unit of weight and 
increases the weight per measured bushel. The volume of 30 pounds 
of seed delinted at a rate of 161 pounds of linters per ton was found 
to be 72.5 per cent, or less than three-fourths, of a bushel and a meas- 
ured bushel of such seed weighed over 41 pounds or 37.8 per cent 
more than the corresponding ginned sample. 
Delinting does not reclean cottonseed but it is a necessary pre- 
requisite for recleaning and grading cottonseed efficiently and eco- 
nomically. The linters on ginned seeds interfere with the operation 
of recleaning machines and prevent an accurate separation of the 
lightweight and the heavyweight seeds when subjected to an air blast. 
Recleaned ginned seeds on the average show little or no reduction 
in the percentage of lightweight seeds contained and slight improve- 
ment as to the inert matter removed, while recleaned delinted seeds 
are practically free of lightweight seeds and inert matter. 
The loss of good seeds in recleaning ginned seed is unnecessarily 
heavy, over 75 per cent of the screenings sometimes being made up 
of heavyweight seeds, while such loss in recleaning delinted seeds 
may be reduced to a negligible quantity. 
The total dockage or shrinkage in delinting and recleaning cotton- 
seed varies with the condition of the seed as it comes from the gin. 
Any variation in the quantity of each class of dockage removed and 
in the price of linters and culled seed affects the net cost of the 
combined operations. 
The cost of delinted and recleaned seed per ton as a basis for deter- 
mining the selling price may be computed by adding the cost of 
delinting and recleaning to the original cost or value per ton of the 
ginned seed, deducting the market value of the linters and culled 
seed removed, multiplying the remainder by 2,000 and dividing the 
product by the number of pounds of recleaned seed obtained from 
a ton. 
The net increase in the cost of delinted and recleaned cottonseed 
is offset by the increased number of seeds and consequent greater 
planting capacity per ton, and the combined operations — delinting 
and recleaning — oner the greatest possibilities for improving cotton- 
seed for planting purposes by mechanical means without increasing 
the cost to the farmer for the quantity required per acre.
