LINT PERCENTAGE AND LINT INDEX OF COTTON. 
11 
Having ascertained the weight of the seeds per hundred from 
Table IV and knowing the percentage of lint, the lint index may 
then be ascertained by reference to Table I. 
■ Table IV. — Number of seeds in a standard sample of 100 grams of seed cotton 
at different lint percentages and weights of seed per hundred.

PLANTERS CAN ESTIMATE THE LINT INDEX. 
Since 100 grams equal approximately 3J ounces, a grower may 
determine with fair accuracy the size of the seeds of the variety he 
plants by ascertaining the number of seeds in 3| ounces of seed cotton 
and referring to Table IV. He can then estimate the lint index of 
his variety by a reference to Table I. For example, if a grower finds 
566 seeds in 3 J ounces of his seed cotton and his cotton is ginning out 
32 per cent of lint, by reference to Table IV the seed will be found 
to weigh 12 grams per hundred. Referring then to Table I, under a 
seed weight of 12 + 32 per cent, the lint index will be found to be 5.64. 
SUMMARY. 
(1) The percentage of lint is the relation between the weight of 
the fiber and the weight of the seeds from which the fiber is obtained 
in the process of ginning and is expressed as a percentage of the un- 
ginned seed cotton. The use of a lint percentage originated with 
buyers of seed cotton, and if used by breeders and growers as a meas- 
ure of the comparative value of varieties it should be employed with
