CAROLINA ESTATE. 



The work of the Carolina estate, near Cienfuegos, will be of great in 

 terest to Louisiana planters. Mr. John O'Rourke, the administrator <>[ 

 this estate, has kindly given me a statement of last season's crop. Th i> 

 is the only house in Cuba employing an eight-roller mill. 



THE MILL. 



This may be termed a combination mill, consisting of four pair- <>t 

 rolls of uniform length and diameter, and driven at the same periphery 

 speed. The rolls are so arranged in a horizontal plane that the cane 

 passes from one pair to the next without the use of a carrier, a narrow 

 knife only being employed. 



Dimensions. 



Periphery speed of rolls from 18 to 20 feet per minute. Maximum 

 capacity of the mill, 30 tons of cane per hour. 



The bagasse is saturated with live steam between the seeond and 

 third, and third and fourth pairs of rolls. 



The mill is double-geared, fifteen to one, i. e., fifteen revolutions of tin 1 

 engine to one of the rolls. The motive power is a pair of engines i'l 

 inch cylinders and 41 inch stroke. The steam for the house is furnished 

 by six boilers 40 by 6 feet; two flues. The milling machinery was built 

 by Brissonneau, Freres & C ie , of Nantes, France. 



TREATMENT OF THE JUICE. 



The juice is defecated in the usual manner. The elear.jnier is drawn 

 off and is clarified by boiling and skimming. The sirup is hoil.-d, 

 Magnolia, in a high-pressure pan. The wm.v.sr <-uitr Tails direetly into 

 the mixer and is centrifugaled hot. Two molas>es sugars aie made.
