Letter from Charles Lush, Esq. to E. H. Towns- 

 end. Esq, Acting Secretary to Government at 

 Bombay, dated Dapooree, the 4th December 1835. 



Sir : 



In compliance with directions in the last 

 paragraph of Mr. Secretary Reed's letter of the 

 22d August, I have the honour to submit a few 

 observations on the subject of separating the seed 

 from cotton, sometimes called cleaning cotton, 

 with sketches and specimens of the instruments 

 in use in this country. The object is more parti- 

 cularly to illustrate the use of the foot-roller as 

 required by the Honourable Court of Directors. 



2. It may be premised, that these several ma- 

 chines simply separate the seed from the cotton. 

 Cleaning, in India, is a distinct process performed 

 by bowing. The bowstring separates the fibres far 

 and wide, the cotton flies up into the air, and any 

 impurity or dirt, heavier than cotton, falls apart 

 to the ground. The brush cylinder of the Ame- 

 rican saw-gin performs the same office. But no 

 such process is ordinarily employed for raw cotton 

 for exportation in India. Bowing is preparatory 

 to spinning. 



3. It has been laid down as a principle, that 

 the best state in which cotton can be prepared for 



packing
