During My Stay In The Plains Of Guines, In 1804, I Endeavoured To Obtain Some Accurate Information Respecting The Statistics Of The Making Of Cane-Sugar.

A great yngenio producing from 32,000 to 40,000 arrobas of sugar is generally fifty caballerias,* or 650

Hectares in extent, of which the half (less than one-tenth of a square sea league) is allotted to sugar-making properly so called (canaveral) and the other half for alimentary plants and pasturage (potrero). (* The agrarian measure, called caballeria, is eighteen cordels, (each cordel includes twenty-four varas) or 432 square varas; consequently, as 1 vara = 0.835m., according to Rodriguez, a caballeria is 186,624 square varas, or 130,118 square metres, or thirty-two and two-tenths English acres.) The price of land varies, naturally, according to the quality of the soil and the proximity of the ports of the Havannah, Matanzas and Mariel. In a circuit of twenty-five leagues round the Havannah the caballeria may be estimated at two or three thousand piastres. For a produce* of 32,000 arrobas (or 2000 cases of sugar) the yngenio must have at least three hundred negroes. (* There are very few plantations in the whole island of Cuba capable of furnishing 40,000 arrobas; among these few are the yngenio of Rio Blanco, or of the Marquess del Arca, and those belonging to Don Rafael Ofarrel and Dona Felicia Jaurregui. Sugar-houses are thought to be very considerable that yield 2000 cases annually, or 32,000 arrobas (nearly 368,000 kilogrammes.) In the French colonies it is generally computed that the third or fourth part only of the land is allotted for the plantation of food (bananas, ignames and batates); in the Spanish colonies a greater surface is lost in pasturage; this is the natural consequence of the old habits of the haciendas de ganado.) An adult and acclimated slave is worth from four hundred and fifty to five hundred piastres; a bozal negro, adult, not acclimated, three hundred and seventy to four hundred piastres. It is probable that a negro costs annually, in nourishment, clothing and medicine, forty-five to fifty piastres; consequently, with the interest of the capital, and deducting the holidays, more than twenty-two sous per day. The slaves are fed with tasajo (meat dried in the sun) of Buenos Ayres and Caracas; salt-fish (bacalao) when the tasajo is too dear; and vegetables (viandas) such as pumpkins, munatos, batatas, and maize. An arroba of tasajo was worth ten to twelve reals at Guines in 1804; and from fourteen to sixteen in 1825. An yngenio, such as we here suppose (with a produce of 32,000 to 40,000 arrobas), requires, first, three machines with cylinders put in motion by oxen (trapiches) or two water-wheels; second, according to the old Spanish method, which, by a slow fire causes a great consumption of wood, eighteen cauldrons (piezas); according to the first method of reverberation (introduced since the year 1801 by Mr. Bailli of Saint Domingo under the auspices of Don Nicolas Calvo) three clarificadoras, three peilas and two traines de tachos (each train has three piezas), in all twelve fondos.
