Three pre-heaters of 108 tubes of 134" x 22' A}i" have been installed, for the evapo- 

 ration of the cane juice, which work, in combination with 2 pre-evaporators of 10' 6" in 

 diameter and have 1,862 copper tubes each of 1^" in diameter by 6V%" in length. Be- 

 sides there are 4 quadruple pieces of 20,000 feet of heat surface each, with independent 

 barametrical condensers. Ten Calandria Vacuum Pans of 13' diameter and independent 

 (barometric) condenser for each one with its necessary tanks for concentrated syrup 

 and molasses and two recipients for massecuite of 8' x 8' 6" x 2 V. 



There are 46 open crystallizers of 8' 10" x 23' long, with grooves, in order to dis- 

 charge the boiled mass from any of the pans, and screw conveyors to discharge the 

 crystallizers into the mixers of the centrifugals. 



24 Hydraulic Centrifugals of 40" x 24" for brown sugar. 



24 Electric Centrifugals of 40" x 24" with independent motors for first and second 

 sugars. 



14 Belt Centrifugals of 40" x 24", divided in two batteries of 7 centrifugals each, 

 driven by electric motors of 75 H. P., also for brown sugar. 



4 Automatic Scales for weighing and packing the sugar. 



3 Steam Vacuum Pumps, two of American manufacture, of 36" x 42", one German 

 make, of 39" x 39", and one Auxiliary Electric Vacuum Pump on the floor of the pans. 



4 Centrifugal Pumps, one of 14,000 gallons injection, another of 12,000 gallons, and 

 two of 5,000 gallons, all with electric motors, and one of 7,000 gallons driven by steam 

 pipes. 



Besides, there is a series of centrifugal pumps driven by electric motors for the 

 juice, the molasses, the syrup and the return water. 



For the plantation and the sugar house service there is an electric plant which con- 

 sists of the following units : — One steam turbine directly connected to a generator of 

 alternating current of 3 phases, 55 cycles, 480 volts and two thousand kilowatts. Two 

 turbines coupled to generators of 1200 kilowatts, and one turbine coupled to a generator 

 of 300 kilowatts, which is used in the dull times. Two magnetos and one switchboard, 

 with all the necessary devices for the operation of these units. 



There is under construction a Standard track of 58 kilometers from the sugar house 

 to Nuevitas in order to connect with the North of Cuba Railroad, the sugar house being 

 already connected by a Standard track with the Cuba Co. in Victoria de las Tunas. 



It has a concrete dock in the Manati Bay, with a draught of thirty feet for the ship- 

 ment of sugar and receipt of materials. 



There is also an ice plant to supply ice for local consumption, with a capacity of 

 6 tons daily. 



The colonos of the Central are over 400, the majority of the colonos being Cubans. 



The percentage of output for about thirty-three acres is about 62,000 arrobas of cane. 



Referring to other things, it is also interesting to note the number of shops to sup- 

 ply what is necessary in an organization of this kind and the many industries and trades 

 required in a progressive town. 



At present two doctors attend efficiently to the sanitary system of the whole plan- 

 tation, having a hospital fitted with the most up-to-date equipment and the necessary help. 



There is a Sport and Recreation Club, as well as a printing shop, and schools for the 

 public instruction. 



There is a local Post Ofiice in the most central part of the property. There is also 

 a beautiful hotel, a theatre, grocery stores and a powerful Wireless Station. 



This brief article will give an idea of the industrial and economic importance of this 

 Central, no doubt one of the best in the Island, the operation of its extensive organiza- 

 tion really causing astonishment, all of which is undoubtedly due to the knowledge and 

 competence of its manager, Mr. Eduardo Diez de Ulzurrun, Marquis of San Miguel 

 de Aguayo, and to the cooperation of all the employees of the Central, who have been 

 chosen with tact to develop and guide the purposes of the Company. 



The last crop ended last month with an output of 543,000 bags of sugar.
