ed from the seed at the moment the saws pass through the '. 



grating ; and the staple is cleaned and brushed off from the 

 saws by the brush wheel which revolves in an opposite 

 direction. 



Twenty-four Cottage saw gins re ceived by the 246 

 Madras Government, 1849. The Cottage saw gins Dispatch 



described above, had been constructed under the direction court of Di- 

 rectors, <th 

 of the Manchester Commercial Association, as being specially ^ rc}l ^

 dispatched to the Madras Presidency, in order that their 

 efficiency might be practically tried. The results of their 

 trial by the Madras Chamber of Commerce, and subse-

 the staple being very much cut up, and rendered
