Besides this profit, another of considerable importance was derived from the feeding of cattle on extensive fields of lucern, and the breeding of hogs. There was also generally, a surplus of maize and beans beyond the consumption of the estate; but without this, according to the valuation made of the whole estate, including buildings, slaves and utensils, which amounted to 962000, the clear profit on this capital exceeded five per cent.; which, with the assistance of the requisite machinery for cultivating and harvesting the cane, and manufacturing the sugar, might be doubled.
I have made no deductions for the food of the slaves, because they were maintained by the produce of the estate, leaving a great surplus for sale; probably as much in value as would defray the expences of their clothing.
The cane usually cultivated in Peru is the creole; but in the year 1802 plants of the Otaheitean cane were first introduced at Guayaquil, by Don Jose Merino, who procured them from Jamaica, whence in 1806 they were brought to some of the plantations of Peru, and from the advantageous result which has been experienced in the growth of this cane, it would follow that the creole will soon be exploded, notwithstanding the assertion, that the sugar obtained from the cane of Otaheite abounds more in mucilage than in essential salt, and that it is susceptible of but a feeble consistency, which exposes it to decomposition on long voyages, or if it be warehoused any considerable length of time. But the Peruvian cultivator has neither of these drawbacks to fear, because there is always an immediate demand for it at home, or the longest voyage to which it is subjected is to Chile.
The Otaheitean cane, on the same land, and with equal labour with the creole, grows to the height of nine or ten feet in eighteen or twenty months, while the creole only grows six in thirty-five or thirty-six months, at which times they are respectively in a state of maturity. The large canes of the former are from seven to eight inches in diameter, but those of the latter seldom exceed three and a half, and the same measure of juice produces nearly the same weight of sugar: besides this, the saving of labour at the mills and manufactory is very great. The cane of Otaheite is more tenacious, and comes from the cylinders whole, while the creole is frequently completely crushed, and incapable of being returned to the operation of the cylinders, on which account a considerable portion of the juice is lost; the pressed cane of Otaheite is also conveyed to the furnace with much more facility than the other.
The cane is usually planted in the foggy season, that it may have taken root before the dry weather commences; the land is prepared by repeated ploughings, and by breaking the lumps of earth with clubs, harrows and rollers for this purpose being unknown. The ploughs are similar to those used in Chile, and which I have already described. If suitable ploughs and other utensils were introduced, it is easy to conceive what great relief would be given to manual labour; and if the horse or mule were substituted for the drowsy, slow-paced bullock, the result would be much more favourable.
The canes are planted in drills made with hoes, so formed, that when the water for irrigation enters the upper end of a field it can flow without any hinderance to the lower; but before this operation of watering takes place the earth is hilled up to the plants. According to the dryness of the season, and the quality of the land, irrigation is repeated three or four times during the summer, and owing to the disposal of the furrows it is neither laborious nor troublesome. The water is generally allowed to remain on the ground twenty-four hours.
When the cane is ripe it is cut close to the ground, and all the leaves are stript off, which with the rubbish are left until the whole field be cut, when they are burnt; and immediately afterwards the roots are irrigated. The cane is carried to the mill on the backs of asses; but for this purpose carts might be used with much saving of labour.
In some parts of the province of Guayaquil and on the coast of Choco the natives, who cultivate the cane for their household consumption of molasses, guarapo, and rum, cut all that is ripe, leaving that which is green; they next bare the roots, mix the soil so obtained with the soil in the furrow, by digging and turning them over, and then hill up the cane again. By repeating this operation every time they cut their cane, they have a constant succession of crops, and the plantation never fails; while in Peru a plantation only yields two crops, for the third is often scarcely sufficient to plant the ground for the ensuing harvest.
The general method of pressing the cane is by means of three vertical grooved brass cylinders, which are put in motion by two pairs of oxen, yoked to two opposite points of a large wooden wheel, placed above the cylinders, and attached at its centre to the axle of the central cylinder, the cogs or teeth of which communicate the rotatory motion to the other two. This tardy method of pressing is used on many plantations; but on the one I am now speaking of vertical water-wheels supply the place of the bullocks, one wheel being attached to each mill. There is however great room for improvement, particularly in the adoption of iron cog and lantern wheels, or at least of metal cogs to the large wheels, iron axletrees, &c.; but rude as the present plan is, the expence of keeping a considerable number of oxen is avoided.
