COMMERCIAL LINT

FIG. 18. LINT LENGTH OP A GOOD SAMPLE. 



A represents the lengths of 100 lint hairs taken at random, and measured 

 in a good commercial sample of Sea Island by O'Neill in 1863 (com- 

 puted from O'Neill's figures), and checked by the author on samples 

 of Egyptian varieties graded as " excellent " for regularity. 



B, the same hairs as A, but mixed together and held in a clamp, to represent 

 the grader's inspection in hand-pulling a sample. A sample which 

 actually shows this amount of irregularity when sorted hair by hair is 

 considered excellent, and pulls with a " hard edge."
