I Have Observed Elsewhere That
In This Comparison Of The Two Branches Of Cultivation It Must Not Be
Forgotten That
The cultivation of sugar requires great capital; for
instance, at present 400,000 piastres for an annual production of
32,
000 arrobas, or 368,000 kilogrammes, if this quantity be made in
one single settlement. At Bengal, in watered lands, an acre (4044
square metres) renders 2300 kilogrammes of coarse sugar, making 5700
kilogrammes per hectare. If this fertility is common in lands of great
extent we must not be surprised at the low price of sugar in the East
Indies. The produce of a hectare is double that of the best soil in
the West Indies and the price of a free Indian day-labourer is not
one-third the price of the day-labour of a negro slave in the island
of Cuba.
In Jamaica in 1825 a plantation of five hundred acres (or fifteen and
a half caballerias), of which two hundred acres are cultivated in
sugar-cane, yields, by the labour of two hundred slaves, one hundred
oxen and fifty mules 2800 hundredweight, or 142,200 kilogrammes of
sugar, and is computed to be worth, with its slaves, 43,000 pounds
sterling. According to this estimate of Mr. Stewart, one hectare would
yield 1760 kilogrammes of coarse sugar; for such is the quality of the
sugar furnished for commerce at Jamaica. Reckoning in a great
sugar-fabric of the Havannah 25 caballerias or 325 hectares for a
produce of from 32,000 to 40,000 cases, we find 1130 or 1420
kilogrammes of refined sugar (blanco and quebrado) per hectare. This
result agrees sufficiently with that of Jamaica, if we consider the
loss sustained in the weight of sugar by refining, in converting the
coarse sugar into azucar blanco y quebrado) or refined sugar. At San
Domingo a square (3403 square toises = 1.29 hectare) is estimated at
forty, and sometimes at sixty quintals: if we fix on 5000 pounds, we
still find 1900 kilogrammes of coarse sugar per hectare. Supposing, as
we ought to do when speaking of the produce of the whole island of
Cuba, that, in soils of average fertility, the caballeria (at 13
hectares) yields 1500 arrobas of refined sugar (mixed with blanco and
quebrado), or 1330 kilogrammes per hectare, it follows that 60,872
hectares, or nineteen five-fourths square sea leagues, (nearly a ninth
of the extent of a department of France of middling size), suffice to
produce the 440,000 cases of refined sugar furnished by the island of
Cuba for its own consumption and for lawful and illicit exportation.
It seems surprising that less than twenty square sea leagues should
yield an annual produce of more than the value of fifty-two millions
of francs (counting one case, at the Havannah, at the rate of
twenty-four piastres). To furnish coarse sugar for the consumption of
thirty millions of French (which is actually from fifty-six to sixty
millions of kilogrammes) it requires within the tropics but nine and
five-sixths square sea leagues cultivated with sugar-cane; and in
temperate climates but thirty-seven and a half square sea leagues
cultivated with beet-root.
