104. STUDIES IN GUJARAT COTTONS 
(2) The kapas gave a ginning percentage and lint-index as follows :— 
Year Ginning percentage Lint-index 
1916-17 42°6 4°06 
1917-18 42°9 4:11 
1918-19 45-4 | 4°85 
1919-20 46-9 | 5°15 
These figures show a tendency, under the conditions of the last two years, 
for both the ginning percentage aud the lint-index to increase. 
(3) The seed was about the average size and 100 seeds weighed as 
follows :—

(4) The lint gave the following average measurements on the different 
parts of the seeds in 1920 :— 
Centimetres 
uint on tip of seed Se Sic 1°63 
Lint on middle of seed ae 1°94 
Lint on base of seed .. Be 1-74 
The variation from the mean (a) at the tip was 7:9 per cent. below, 
( b ) at the middle 9°6 per cent. above, and (¢) at the base 1-7 per cent. below. 
The lint on the middle of the seed varied as follows, as determined from 
100 measurements made on seeds :—
