Mean length = i'444 inch. 



Longest fibre =o*6o6 inch greater than mean. 



Shortest fibre =0*344 inch less than mean. 



This cotton presents the longest hair I have measured, 

 and shows a difference of nearly i inch between the longest 

 and shortest hairs. This is a considerable range ; but the 

 average stands high. 



These four examples of cotton, viz. three Sea Island and 

 one Queensland, may be called our long-staple cottons. 

 Egyptian is, I believe, also reckoned a long staple ; but be- 

 tween it and the shortest Sea Island there is a wider gap 

 than occurs between any two succeeding qualities taken 

 in the order of their lengths ; we may therefore consider 

 them as a group. The Edisto Island cotton, however, 

 stands out alone; being 0'i8 inch longer in the mean than 

 the next highest Sea Island, it may be taken as excep- 

 tionally long. The other three samples are very nearly 

 of the same length in the mean, Queensland standing be- 

 tween two different samples of Sea Island, being 0*026 inch 

 shorter than one, and 0*03 1 inch longer than the other : the 

 longest hair of the Queensland is from 0*25 to 0*15 shorter 

 than the longest hairs of the Sea Island; but, on the other 

 hand, its shortest hairs are o* i inch longer than the shortest 

 hairs of the Sea Island.
