It should be understood that these figures are given only as an 
indicator of the approximate cost and of the factors which must be 
taken into consideration in determining the cost. The relative im- 
portance of these factors will vary from time to time. It will be 
noted that " dockage " appears to be the greatest item of cost. In 
addition to the linters removed there is always more or less loss in 
weight of the seed through the removal of dirt and trash by passing 
through the delinting machines. The total dockage must be charged 
for at the value of the ginned or undelinted seed. In the example 
given this value is assumed to be $40 per ton. To reduce this heavy 
charge against dockage there are 100 pounds of linters to which are 
assigned a market value of 3 cents per pound, or $3.

Fig. 3. — General layout or plan of two-unit delinting plant. Note : Xo attempt is made 
here to show the details or to suggest a fixed plan of installation. Manufacturers 
no doubt will be glad to cooperate with prospective buyers in working out the most 
economical and efficient plan of installing and operating such machinery under varied 
conditions and for any special requirements 
To offset further the loss of 180 pounds per ton dockage which has 
been charged to the cost of delinting, there is the fact that the num- 
ber of seed per pound increases in an equal or a greater proportion 
than the percentage of dockage. In this case the total dockage is 9 
per cent, while the number of delinted seed per pound is approxi- 
mately 10 per cent greater than the number of ginned seed. The 
greater number of seed per pound increases the commercial value and 
planting capacity per unit, 
A plant of one-half this capacity may be installed at $700 to $1,000 
less. The net cost of delinting cottonseed in such a plant when 
operated 125 days per season is about $7.50 per ton. or approxi- 
mately 50 per cent greater than in the larger plant. The capacity of 
plant to be installed by a dealer will depend upon the volume of seed
