possible to alter the construction of the gearing wheels. 

 &c 3 of the rollers of wind mills, (when the rollers are 

 horizontal,) so as very much to increase the yielding of 

 juice, by decreasing the velocity of the rollers ; but the 

 speed could not be regulated with exactness from the 

 irregularity of the motive power. The frame-work, 

 gudgeons, and wheels must also be made more massive 

 than usual, to enable them to resist the additional force 

 which would be developed. Every part of the mill with 

 which the cane-juice comes in contact, and all spouts and 

 strainers, should be formed of metal, as wood absorbs a 

 portion of the liquid, which becomes acid, and communi- 

 cates the taint to every succeeding portion with which it 

 comes into contact.
