After lining out the ground and marking the intersections by slight stakes the next business is to plant the trees that are to become props to the pepper, as the Romans planted elms, and the modern Italians more commonly plant poplars and mulberries, for their grape-vines.  These are cuttings of the chungkariang (Erythrina corallodendron), usually called chinkareens, put into the ground about a span deep, sufficiently early to allow time for a shoot to be strong enough to support the young pepper-plant when it comes to twine about it.  The cuttings are commonly two feet in length, but sometimes a preference is given to the length of six feet, and the vine is then planted as soon as the chinkareen has taken root:  but the principal objections to this method are that in such state they are very liable to fail and require renewal, to the prejudice of the garden; and that their shoots are not so vigorous as those of the short cuttings, frequently growing crooked, or in a lateral instead of a perpendicular direction.  The circumstances which render the chinkareen particularly proper for this use are its readiness and quickness of growth, even after the cuttings have been kept some time in bundles,* if put into the ground with the first rains; and the little thorns with which it is armed enabling the vine to take a firmer hold.  They are distinguished into two sorts, the white and red, not from the colour of the flowers (as might be supposed) for both are red, but from the tender shoots of the one being whitish and of the other being of a reddish hue.  The bark of the former is of a pale ash colour, of the latter brown; the former is sweet, and the food of elephants, for which reason it is not much used in parts frequented by those animals; the latter is bitter and unpalatable to them; but they are not deterred by the short prickles which are common to the branches of both sorts.

(Footnote.  It is a common and useful practice to place these bundles of cuttings in water about two inches deep and afterwards to reject such of them as in that state do not show signs of vegetation.)

Trial has frequently been made of other trees, and particularly of the bangkudu or mangkudu (Morinda citrifolia), but none have been found to answer so well for these vegetating props.  It has been doubted indeed whether the growth and produce of the pepper-vine are not considerably injured by the chinkareen, which may rob it of its proper nourishment by exhausting the earth; and on this principle, in other of the eastern islands (Borneo, for instance), the vine is supported by poles in the manner of hops in England.  Yet it is by no means clear to me that the Sumatran method is so disadvantageous in the comparison as it may seem; for, as the pepper-plant lasts many years, whilst the poles, exposed to sun and rain, and loaded with a heavy weight, cannot be supposed to continue sound above two seasons, there must be a frequent renewal, which, notwithstanding the utmost care, must lacerate
