MARKETING COTTONSEED FOR PLANTING PURPOSES 15 
SACKING 
It is economy to sack cottonseed as it comes from the recleaning 
and grading machine. Storing it in bulk and sacking later necessi- 
tates rehandling, and two men will be required to do the work, 
whereas if the recleaner and grader is equipped with a simple 
elevator and bagging attachment one man can sack the seed as fast 
as it comes from the machine. An automatic weigher and bagger 
may be used profitably where large quantities of cottonseed, either 
alone or in connection with other kinds of seed, are handled. 
New bags, either cotton or burlap, should be used. If cotton bags 
are preferred, it is not necessary that they be of the heavy grade 
used for grass, clover, and other small seeds. However, they should 
be strong enough to withstand rough handling in shipment. Bags 
of 8-ounce burlap are satisfactory and are much used, although some- 
times bags of 10-ounce burlap or heavier are preferred. The bags 
should have a capacity of 100 pounds net, when sewed or tied, and 
be filled to even weight. The strong point in favor of a bag of this 
size is that cottonseed always should be sold by the 100 pounds in- 
stead of by the bushel. This point is discussed more fully on page 
21. In closing the bags sewing either by hand or machine is prefer- 
able to tying. 
STORAGE 
Cottonseed may be stored either in bulk or in sacks. In either 
case the main precaution is to prevent the seed from heating. In- 
vestigations show that the germination of cottonseed is injured 
oftener by heating in storage than is generally believed. The direct 
cause of such heating is excessive moisture. The extent of the dam- 
age from heating is directly in proportion to the percentage of 
moisture contained and indirectly to the rapidity of drying. Seed 
cotton picked early in the season while " green " or at any time when 
moist and stored in a close bin or building is subject to heating. If 
cotton is ginned while " green " and the seed stored in large piles 
such seed becomes heated quickly, and constant stirring or aerating 
is necessary if it is to be preserved for planting. 
WAREHOUSE SHOULD BE VENTILATED 
The seed should be dry when stored and the warehouse well ven- 
tilated. A warehouse admirably serving the purpose is one having 
a floor clearance at least 12 inches above the ground, with double 
walls, and having ample ventilation under the floor and between the 
top of walls and roof. Concrete floors are not desirable, and if the 
building is of brick or concrete construction the seed, whether in 
bulk or sacked, should not be piled high against the walls, as con- 
siderable damage to the seed is likely to result. If, however, it is 
necessary to use a building having a concrete floor, the danger of 
heating may be lessened greatly, if not entirely prevented, by sacking 
the seed and stacking the sacks, in the manner outlined on page 16, 
on a slatted false floor built by laying 2 by 4 inch stringers edge- 
wise on the concrete floor and nailing 1 by 4 inch strips across them, 
leaving a 2-inch space between each strip. Similar results may be 
had by simply laying three 4 by 4 inch stringers on the floor about
