Three species of sugar cane can be distinguished even at a distance, by the colour of their leaves; the ancient Creole sugar cane, the Otaheite cane, and the Batavia cane. The first has a leaf of a deeper green, the stem less thick, and the knots nearer together.--This sugar cane was the first introduced from India into Sicily, the Canary Islands and the West Indies. The second is of a lighter green; and its stem is higher, thicker, and more succulent. The whole plant displays a more luxuriant vegetation. We owe this plant to the voyages of Bougainville, Cook, and Bligh. Bougainville carried it to the Isle of France, whence it passed to Cayenne, Martinique, and since 1792, to the rest of the West India Islands. The sugar cane of Otaheite, the _To_ of those islanders, is one of the most important acquisitions, for which colonial agriculture is indebted to the travels of naturalists. It yields not only one third more of juice than the Creolian cane on the same space of land; but from the thickness of its stem, and the tenacity of its ligneous fibres, it furnishes much more fuel. The last advantage is important to the West Indies, where the destruction of the forests has for a long time obliged the planters to use the canes deprived of their juice, to keep up the fire under their boilers. But from the knowledge of this new plant, the progress of agriculture on the continent of Spanish America, and the introduction of the East India and Java sugars, the revolutions of St. Domingo, and the destruction of the great sugar plantations of that island, would have had a more sensible effect on the prices of colonial produce in Europe. The Otaheite sugar cane was carried from the Isle of Trinidad to Caraccas. From Caraccas it passed to Cicuta and San Gil in the kingdom of New Grenada. In our days its cultivation during twenty-five years almost entirely removed the apprehension, which was at first entirely entertained, that, transplanted to America, the plant would by degrees degenerate, and become as slender as the Creole cane. If it be a variety, it is a very constant one. The third species, the violet sugar cane, called _Cana de Batavia_, or _de Guinea_, is entirely indigenous in the island of Java, where it is cultivated in preference in the districts of Jupara and Pasuruan. Its foliage is purple, and very broad; and it is preferred in the province of Caraccas for rum. The _tablones_, or grounds planted with sugar canes, are divided by hedges of a collossal gramen; the latta, or gynesium with distich leaves. _American Fig Tree_.
