THE CUBA REVIEW 



toneladas de carbon durante 300 dias del ano. Para resarcirce por la perdida de calor, 

 esto OS de mucha consideracion, aun con combustible barato. 



Otro asunto que debe considerarse es el acabado exterior del forro. Hemos hallado 

 que con el mismo forro la condcnsacion variara hasta un 20 por cicnto, ya se usen 

 lonas enipastadas regulares y bandas 6 algun otro acabado exterior. Los resultados 

 varian tambien con el distinto material usado para el aislamiento. 



Los encargados e ingenieros de ingenios deberian pensar esto detenidamente, pues 

 es una de las grandes economicas que pueden hacerse en las instalaciones industriales, 

 y todos los tubos conducentes de vapor deberian ser aislados como es debido, con objeto 

 de impedir que tenga lugar la condcnsacion del vapor. 



FURTHER DATA OF SUGAR COSTS 



Following United States Consul-General Starrett's investigations into the cost of 

 establishing a sugar mill in Cuba, which were printed in the June issue of The Cuba 

 Review, comes a bulletin issued by the Cuban Department of Agriculture along the 

 same lines. 



In this bulletin is a table showing the cost of preparing and cultivating one acre of 

 cane land in Cuba, which is reproduced below : 



Preparation of Land 



Clearing land for plowing from $1.50 to $10.00 



Cost of first plowing 4.00 6.20 



Cost of second plowing 2.70 3.00 



Cost of harrowing 1.00 1.25 



Marking and cleaning ; 1.25 1.65 



$10.45 $22.10 



Cost of Planting 



Cost of seed cane $4.00 to $ 5.00 



Cost of hauling .50 .70 



Cutting in pieces .50 .80 



Distribution of same 2.50 3.50 



Covering 3.00 3.80 



Cost of Cultivation 



First cultivation $4.00 to $ 4.50 



Second cultivation 2.75 3.10 



Third cultivation 1.60 2.00 



Three cleanings 2.20 3.00 



Cutting and Hauling to Mill 



Cutting and loading $12.75 to $18.00 



Hauling 9.00 18.00 



10.50 13.80 



10.55 12.60 



21.75 36.00 



Total $53.25 $84.50 



According to the bulletin, when replanting is necessary, the work can be done at an 

 expense ranging from $15 to $20 per acre. With land producing 60,000 arrobas* of cane 

 per caballeria** the crop lasting six years without replanting, the results would be 

 approximately as follows : 



Cost of making and harvesting first crop, per acre $60.00 



Cost of making and harvesting 5 sul)sequent crops @ $40 per acre 200.00 



$260i.O0 

 Yield of 6 years to growers, or 2,605.44 lbs. (a) $2.80 equals times $72.95 437.00 



Gain in 6 years $177.70 



Caballerias of good, new land often produce 100,000 arrobas of cane, and sometimes 

 will not require replanting for 15 or 20 years. If irrigation is available, and intense 

 cultivation is employed, it is possible to raise the production to 160,000 or even to 

 200,000 arrobas of cane to the caballeria. 



* 1 arroba = 25 lbs. ** 1 caballeria = 33J acres.
