In 1972 my students and some of the Chief Mamady's sons invited me to help squeeze sugar cane juice using the Chief's 'new' mechanical box. Crushing efficiency was critical to the success of his sugar cane farm. Every possible amount of juice needed to be squeezed. While it was an enjoyable afternoon with my students in Kolila, Liberia (a village of 210 according to a 1972 census where I was the very first Peace Corps volunteer), we were frustrated that taking turns squeezing the sugarcane for several hours left too much juice in the reeds.
