DELINTING AND RECLEANING COTTONSEED FOR PLANTING. 9 
pounds 3 was required to force enough ginned seeds into the kettle to 
test 30 pounds per bushel, which was the basic weight desired. 
Test weights were then made with seeds delinted at varying rates, 
applying the same pressure in each case as was required for ginned 
seed to test 30 pounds. The weights per bushel as shown by these 
tests, together with the volume of 30 pounds in terms of a bushel, 
are given in Table 6. A comparison of the weight per bushel and 
volume per unit of weight of delinted seed with that of ginned seed 
also is shown graphically in Figure 5.

3 The pressure required varies with different varieties and may vary with different lots of the same 
variety. The pressure of 13} pounds applies only to this test which was made to determine t he comnarative 
weight per bushel ofginned and delinted seed as a basis for computing the comparative volume and not 
to fix a standard pressure to be used in making test weights of cottonseed. Tests made with the Cleveland 
variety show a similar relationship between the weight per bushel of delinted and ginned seed of that 
variety and theindications are that when tests with any variety are made i n accordance with the procedure 
outlined here the comparative results will be little differen t from those obtained with t lie Express variety 
although varying degrees of pressure may be required to force enough ginned seeds into the quart kettle 
to test 30 pounds per bushel.
