Numerous families, from the high[115] country of the interior, soon afterwards emigrated to the sea coast; for it had become an imperious duty on the part of the rajah, on whom a miraculous cure had been so unexpectedly wrought by the fruit of the cocoa-nut tree, to give publicity to the circumstances which originally introduced to him and his followers a knowledge of that splendid production; whilst the conviction of its transcendent utility pointed out its propagation as a never-failing source of individual advantage and of progressive national prosperity. This useful tree is of the Monoecious class, order Hexandria, and is the Cocos[116] nucifera of Linnæus: it is called Haari by the Tahitans, Polgaha by the Singalese. The varieties of the cocoa-nut are numerous at Tahiti, (one of the Society Islands.) I am acquainted with six, each having a distinct appellation by the natives. At Ceylon, five varieties are indigenous; but are seldom, if ever, found in the same plantation, except it be in the vicinity of a Budhoo temple of some importance. The first, or King cocoa-nut may be well known to those who have resided in Ceylon: its bright orange colour, and somewhat oval shape, cannot fail to attract notice, and is usually presented to respectable Europeans, by the Modeliars, or by the priests, as a compliment to those whose curiosity may have induced a visit to the shrine of Budhoo. This variety is the Tembili of the Singalese, and they have of it three sub-varieties. The second is of a similar colour to the preceding, but of a more spherical shape. The third is of a pale yellow, and rather heart-shaped: it is the _Nawasi_, or edible husk, and has the peculiar quality, that after the epidermis has been removed, the inner rind turns to a pale red, and is edible. The fourth is the common cocoa-nut, which is in general use, and the one most known. The fifth is a species of Maldivia, or dwarf cocoa-nut, about the size of a turkey’s egg, which being rare, is more esteemed as a curiosity than for any peculiar good quality it possesses. The elevation[117] this tree attains is from sixty to one hundred feet, and a diameter of one or two feet; its cylindrical stem, crowned on the summit with numerous waving, plumy branches, has a splendid effect, and forms an elegant object of intertropical scenery: it is seen on the arid, sandy shores, with its roots laved by the surges, as well as in the rich valleys, overshadowing the huts of the natives; but when this valuable tree is found growing inland, they are inferior in size to those on the sea-shore and about the dwellings of natives. The Singalese have a saying, that cocoa-nut trees do not thrive unless “you walk amongst them, and talk amongst them.”[118]
