When the plant approaches maturity, a gummy substance exudes from the leaves; this is gathered by men clothed in dry raw hides, who, by walking through the plantation, become covered with this gum or glue. This is scraped off and carefully preserved, being the very essence of the plant, and exceedingly powerful in its effects.

The sensation produced by the properties of this shrub is a wild, dreamy kind of happiness; the ideas are stimulated to a high degree, and all that are most pleasurable are exaggerated till the senses at length sink into a vague and delightful elysium.

The reaction after this unnatural excitement is very distressing, but the sufferer is set all right again by some trifling stimulant, such as a glass of wine or spirits.

It is supposed, and confidently asserted by some, that the Indian hemp is the foundation of the Egyptian "hashisch," the effects of which are precisely similar.

However harmless the apparent effect of a narcotic drug, common sense must at once perceive that a repeated intoxication, no matter how it is produced, must be ultimately hurtful to the system. The brain, accustomed to constant stimulants, at length loses its natural power, and requires these artificial assistants to enable it to perform its ordinary functions, in the same manner that the stomach, from similar treatment, would at length cease to act. This being continued, the brain becomes semi-torpid, until wakened up by a powerful stimulant, and the nervous system is at length worn out by a succession of exciting causes and reactions. Thus, a hard drinker appears dull and heavy until under the influence of his secret destroyer when he brightens up and, perhaps, shines in conversation; but every reaction requires a stronger amount of stimulant to lessen its effect, until mind and body at length become involved in the common ruin.

The seed of the lotus is a narcotic of a mild description, and it is carefully gathered when ripe and eaten by the natives.

The lotus is seen in two varieties in Ceylon—the pink and the white. The former is the most beautiful, and they are both very common in all tanks and sluggish streams. The leaves are larger than those of the waterlily, to which they bear a great resemblance, and the blossoms are full double the size. When the latter fade, the petals fall, and the base of the flower and seed-pod remains in the shape of a circular piece of honeycomb, full of cells sufficiently large to contain a hazel-nut. This is about the size of the seed, but the shape is more like an acorn without its cup. The flavor is pleasant, being something like a filbert, but richer and more oily.

Stramonium (Datura stramonium), which is a powerful narcotic, is a perfect weed throughout the island, but it is not used by the natives otherwise than medicinally, and the mass of the people are ignorant of its qualities, which are only known to the Cingalese doctors. I recollect some years ago, in Mauritius, where this plant is equally common, its proprieties were not only fully understood, but made use of by some of the Chinese emigrants. These fellows made cakes of manioc and poisoned them with stramonium. Hot manioc cakes are the common every-day accompaniment to a French planter's breakfast at Mauritius, and through the medium of these the Chinese robbed several houses. Their plan was simple enough.

A man with cakes to sell appeared at the house at an early hour, and these being purchased, he retired until about two hours after breakfast was concluded. By this time the whole family were insensible, and the thieves robbed the house at their leisure. None of these cases terminated fatally; but, from the instant that I heard of it, I made every cake-seller who appeared at the door devour one of his own cakes before I became a purchaser. These men, however, were bona fide cake-merchants, and I did not meet with an exception.

There are a great variety of valuable medicinal plants in the jungles of Ceylon, many of which are unknown to any but the native doctors. Those most commonly known to us, and which may be seen growing wild by the roadside, are the nux vomica, ipecacuanha, gamboge, sarsaparilla, cassia fistula, cardamoms, etc.
