6. The chief use the natives appear to make of the rose water, or the sandal attar as they term it, is at the period of their festivals and weddings. It is then distributed largely to the guests as they arrive, and sprinkled with profusion in the apartments. A large quantity of rose water is sold at Benares, and many of the native Rajahs send over to Ghazipoor for its purchase. Most of the rose water, as soon as distilled, is taken away, and after six months from the termination of the manufacture there are not more than four or five places where it is to be met with.
I should consider that the value of the roses sold for the manufacture of rose water may be estimated at 15,000 to 20,000 rupees a year; and from the usual price asked for the rose water, and for which it is sold, I should consider there is a profit of 40,000 rupees. The natives are very fond of using the rose water as medicine, or as a vehicle for other mixtures, and they consume a good deal of the petals for the conserve of roses, or goolcond as they call it.
The roses of Ghazipoor, on the river Ganges, are cultivated in enormous fields of hundreds of acres. The delightful odor from these fields can be scented at seven miles distance on the river. The valuable article of commerce known as attar of roses is made here in the following manner:—On 40 pounds of roses are poured 60 pounds of water, and they are then distilled over a slow fire, and 30 pounds of rose water obtained. This rose water is then poured over 40 pounds of fresh roses, and from that is distilled at most 20 pounds of rose water; this is then exposed to the cold night air, and in the morning a small quantity of oil is found on the surface. From 80 pounds of roses, about 200,000, at the utmost an ounce and a-half of oil is obtained; and even at Ghazipoor it costs 40 rupees (4l.) an ounce.
Five guineas have been often paid for one ounce of attar of roses. The most approved mode of ascertaining its quality is to drop it on a piece of paper; its strength is ascertained by the quickness with which it evaporates, and its worth by its leaving no stains on the paper. The best otto is manufactured at Constantinople.
A volatile oil, erroneously called oil of spikenard, is met with in the shops, which is obtained from a plant which has been named by Dr. Royle, the Andropogon Calamus aromaticus.
The true spikenard of the ancients is supposed to have been obtained from the Nardostachys Jatamansi, a plant of the Valerian family. Dr. Stenhouse describes rather minutely ("Journal Pharm. Soc." vol. iv. p. 276) a species of East India grass oil, said to be the produce of Andropogon Ivaracusa, which he believes to be what is usually called the oil of Namur. It has a very fragrant aromatic odor, slightly resembling that of otto of roses, but not nearly so rich. Its taste is sharp and agreeable, approaching that of oil of lemons. It has a deep yellow color, and contains a good deal of resinous matter.
LEMON GRASS (Andropogon schœnanthus).—This fragrant grass, which is now cultivated very generally throughout the West Indies, in the gardens of the planters, as an elegant and powerful diaphoratic, was doubtless introduced from the East. The active principle of the leaves seems to reside in the essential oil which they contain. Lemon grass oil forms an important article of export from Ceylon, amounting in value to nearly £7,000 annually.
The Andropogon schœnanthus, which may be seen covering all the Kandian hills, is the best possible pasture for cattle—at least as long as it is young. This species of grass is very hard, and grows to the height of seven feet, and sometimes higher, and has a strong but extremely pleasant acid taste. It derives its name from having, when crushed, an odor like that of the lemon, so strong, that after a time it becomes quite heavy and sickening, although grateful and refreshing at first. It covers the hills in patches—those, at least, that are not overgrown with jungle and underwood—and it is to be found nowhere but in the Kandian district. Spontaneous ignition frequently takes place, and the appearance of the burning grass is described as most magnificent. A few days after, from the midst of this parched, blackened, and apparently dead ground, lovely young green shoots begin to arise—for the roots of this extraordinary grass have not even been injured, far less destroyed, by the fire; and in a very short time the whole brow of the mountain is again overspread with tufts of beautiful green waving grass.—("Journal of Agriculture.")
Otto of khuskhus or scented grass, from another species, A. digitalis, obtained at Ulwar in the States of Rajpootanah, was shown at the Great Exhibition in 1851, and Newar oil (from A. maritima) from Agra.
CITRONELLA OIL.—In the Southern province of Ceylon some half dozen estates about Galle are cultivated with citronella grass. The exports of this oil from Ceylon in the last three years have been as follows:—1850, 86,048 oz., valued at £3,344; 1851, 114,959 oz., valued at £3,742; in 1852, 131,780 oz., valued at £2,806.
