COTTON-WOOL.

The Company's Agent at Rio-de- Janeiro has iiep«rt. 

 stated, that the machines used at Maranham are 

 the Indian Roller" and the " North American 

 Saw-gin."* He had not then ascertained the 

 practice at Bahia and Pernambuco. From Egypt 

 the Court have imported a machine of very rough 

 and simple construction, which is on the roller 

 principle. The Indian churka and foot-roller have 

 recently been received from Bombay. 



One of the Whitney's Saw-gins imported from 

 North America in 1829 has been retained at home 

 as a model. Plates of this machine, of the Indian 

 churka, Indian foot-roller, and of the Egyptian 

 machine, wdll be found in this volume. 



* The saw-gin which is used for the greater part of the North 

 American cotton, appears to be disadvantageous to the long 

 stapled cotton of Maranham. The value of the cotton of that 

 Province is quoted in the English market thus: 

 d. d. 



Maranham .. 12 to 13J per lb. 



Ditto saw-ginned io| to ii| do. (October 1836.) 



There is generally the like difference in value.
