DELIXTIXG AND RE CLEANING COTTONSEED FOB PLANTING 
11 
The presence of lightweight seeds is not easily discernible by a 
casual examination, but detailed analyses of a number of recleaned. 
ginned samples show conclusively the necessity for delinting the seeds 
before they can be recleaned effectively. Samples of each of ginned 
and recleaned seed were submitted by a number of dealers who 
reclean cottonseed without delinting. Weights of each of 100 seeds 
in each sample were made with the results as shown in Table 7.

Percent-

8 centi- 
grams. 
The average percentage of the seeds in the samples submitted by 
the 10 dealers in the foregoing: table, weighing less than 8 centigrams 
each, is practically the same for the ginned or unrecleaned as for the 
recleaned seed — 7.2 and 7.3 per cent, respectively. It may be seen 
readily from the individual tests that there is little or no improvement 
in the recleaned seeds over the original ginned sample in each lot. 
Much of the inert matter — trash, burs, dirt, and loose particles of lint — 
is removed, but the percentage of lightweight seeds remaining is prac- 
tically the same. (See Pis. II and III, and fig. 6, a.) 
Delinting partially recleans the seed, removing the surplus lint and 
some of the inert matter, but it does not eliminate the lightweight, 
immature seeds and much of the trash. Analyses of delinted sam- 
ples which had not been recleaned showed that the percentage of 
lightweight seeds present was the same as before delinting. How- 
ever, delinting does facilitate recleaning. Samples of recleaned de- 
linted seed analyzed contained only 20 to 25 per cent as many light- 
weight seeds as the delinted or the ginned samples from the same lot. 
Detailed results of these analyses are given in Table 8 and illustrated 
in Plates IV. V. and VI. and graphically in Figure (>, 1>. There i> a
