Sugar Curiosities - Mark Twain

How mark Twain described a sugar cane mill:

 "The process of making sugar is exceedingly interesting. First, you heave your cane into the centrifugals and grind out the juice; then run it through the evaporating pan to extract the fibre; then through the bone-filter to remove the alcohol; then through the clarifying tanks to discharge the molasses; then through the granulating pipe to condensate it; then through the vacuum pan to extract the vacuum.
