As the cane is bought from the persons raising it by sugar content, every 10th or 15th car is isolated for special analysis. Automatic rake unloaders similar to those in Hawaii. Crushing in two sets, each made up of board belt, cutting knives, shreaders and 3 mills of 3 rollers. The rollers all have the same size grooves (medium) and obtuse v-shaped depressions to prevent slipping.

Hot juice and water are abundantly sprayed on the bagass after each crushing and the ma- terial is pushed through two long juice and water baths. The dilution is as much as the evaperators will stand. The heating is the same as in Hawaii. More lime is added than in Hawaii, the lime being made on the premises from coral limestone. There are no set- tling tanks, a perpetual settling device taking their place. This consists of a circular tank cone-shaped at the bottom with a spiral partition. Settling Device
