[>-0. 3, KTW SERIES, 
The Roller Gin is still iLsed for finer Sea Island Cotton, which 
would be iiijnred by the Saw Gin. I am told, that the Saw Gin 
has bee'i in:proved by a mechanic in the service of the East India 
Coinpany, from whom he has received a pecuniary acknowledgment 
for the improvement. An American gentleman, new in this conn- 
try, has patented a different mode of cleaning, wi'wh all the celerity 
of the Saw Gin, without injuring the staple ; not only removing 
the seeds, bnt even the small motes which weaken the thread and 
render the web rough and irregular. 
SCREW PRESS. 
The other essential Implement to enable African or other Cot- 
ton to compete with American is the Screw-Press. By compres- 
sing the wool into a compact and square, instead of a bulky and 
round bale, it can be brought at a freight of one farthing to one 
half-penny per lb. which, otherwise, could not be shipped here 
under one penny or three half-pence per lb. 
The cotton is thrown into a square box, and by means of a screw 
it is pressed upwards against a beam, where the compactness of 
the bale is secured by ropes previously arranged. 
CLE.\KING COITOX FKOM DIFFERENT KINDS OF 5EED. 
It is of importance to attend to the seeds being covered with a 
thick down, or comparatively bare, and free from down. When 
they are covered with a close adhesive down, however fine may be 
the staple of the surrounding Cotton, the seeds are so difficult to 
clem by the best Boiler Gins as to make the article unremunera- 
tlve ; when the fine sorts are cleaned by the Saw Gin, they may 
be torn and so reduced to the better qualities of New Orleans or 
Egyptian, worth from 6rf. to ^d. per lb. 
If the seed is of the fine stapled sort, and bare of down, then 
the Roller Gin may be employed, as injuring the fibre less than 
the Saw Gin ; of this kind is the American Sea Island, which, 
when so cleaned, brings I2d. to \^d. per lb. The Anguilla and 
*cme of the indigenous sorts of British Honduras, comparatively 
bare of down, could be advantageously cleaned by the Roller Gin, 
and are considered to resemble Sea Island. Hand picked samples
