The banana seems, however, to be found no higher than 4,600 feet in a state of perfection.
No fruit is so easily cultivated as are the varieties of the plantain. There is hardly a cottage in the tropics that is not partly shaded by them; and it is successfully grown under other fruit trees, although it is independent of shelter. Its succulent roots and dew-attracting leaves render it useful in keeping the ground moist during the greatest heats. The plantain may be deemed the most valuable of fruits, since it will, in some measure, supply the place of grain in time of scarcity. To the negroes in the West Indian Islands the plantain is invaluable, and, like bread to the Europeans, is with them denominated the staff of life. In Jamaica, Demerara, Trinidad, and other principal colonies, many thousand acres are planted with these trees.
The vegetation of this tree is so rapid that if a line of thread be drawn across, and on a level with the top of one of the leaves, when it begins to expand, it will be seen, in the course of an hour, to have grown nearly an inch. The fruit when ripe is of a pale yellow, about a foot in length and two inches thick, and is produced in bunches so large as each to weigh 40 lbs. and upwards.
The soil best suited to the growth of the plantain is found in the virgin land most recently taken in from the forest, having a formation of clay and decomposed vegetable substances. A large portion of organic matter is required, as well as clay or other ponderous strata, to afford the greatest production of fruit. I have known good plantains produced in the West Indies, upon land considerably exhausted by the culture of cotton, but which was enriched by the application of a quantity of the decomposed seed of that shrub near the roots of the young plantains.
In the Straits' settlements of the East, the following are the most approved varieties:—The royal plantain, which fruits in eight months; one which bears in a year, the milk plantain, the downy plantain, and the golden plantain or banana. A species termed gindy has been lately imported from Madras, where it is in great request. It has this advantage over the other kinds, that it can be stewed down like an apple while they remain tough.
The Malays allege that they can produce new varieties, by planting three shoots of different sorts together, and by cutting the shoots down to the ground three successive times, when they have reached the height of nine or ten inches.
About 144 suckers of the plantain are set on an orlong (1⅓ acres), each of which spreads into a group of six or eight stems, of about six inches to one foot in diameter, which yield each a bunch of fruit, and are then cut down, when fresh shoots succeed. In very rich soils the plant will continue to bear for twenty years, but otherwise it is dug up after the seventh or eighth year. The cost of cultivating 100 orlongs of land exclusively with plantains, will be nearly 2,000 Spanish dollars until produce be obtained. About 43,200 bunches may be had afterwards yearly, which might give a return of 2,160 dollars, or, deducting the cost of cultivation and original expenses, a profit per annum of 1,450 dollars.
The plantain has frequently been suggested as an article of export from our colonies. A few bunches are occasionally brought over by the Royal West India Mail Company's steamers running to Southampton, but more as a curiosity than as articles of commerce.
In its ripe state no unexceptionable and sufficiently cheap method of preserving it has yet been suggested.
In some districts of Mexico it is, indeed, dried in the sun, and in this state forms a considerable article of internal commerce under the name of "plantado pasado."
