In the above, I have taken the _attar_ at far less than the price it at present bears, and the rose-water at the rate usually charged at Juanpore, Lucknow, &c. for a maund of the best rose-water, at the time Colonel Polier’s experiment, above detailed, was dated, namely, in 1787. If my information is correct, the best _attar_ now sells at Calcutta for near six guineas the ounce; and the best rose-water at Juanpore, where a large quantity is distilled, for thirty-five and forty rupees per maund. The expence of the cultivation is taken at about seven rupees monthly, on an average; there being no work of consequence performed, except hoeing, for full eight months in the year. The rent of the land is rated at the ordinary medium at which I compute soils suited to the growth of tobacco, cotton, sugar, opium, &c. to be of late, that is, at about 2½ rupees, or eight shillings per _bigah_. In Doctor Willich’s Encyclopædia, I observe it is stated, that genuine _attar_ sells, even in the East Indies, at twenty guineas the ounce; but I apprehend this to be a great error; at least, it is far beyond what the experience of more than twenty years allows me to credit. If, indeed, the Doctor means that which the _gundies_ retail, by mixing only _one drop_ of genuine _attar_ among pint of oil of sandal-wood, as is often practised, he is far short of the mark; for, in such case, the ounce may be said to sell for nearer fifty, than twenty guineas. The color of _attar_, is remarked by Colonel Polier, ‘to be no criterion of its goodness, its quality, or its country.’ That gentleman states, that he had, in the same year, and from the same rose-bushes, _attar_ of a fine emerald green, of a bright yellow, and of a reddish hue, all obtained by the same process, only that the roses were collected on different days. Here I am disposed to suspect, that the old trick, so peremptorily detected by Doctor and Professor Gilchrist, of mixing a solution of verdigris, or other coloring matter, in the still, or in the receiver, must have been practised by some of the Colonel’s attendants. It has been sufficiently proved, that, when no such adulteration takes place, _attar_ very nearly limpid: but, though a color may be thus imparted, it does not appear that the perfume is debased; its fragrance being unimpaired: on the other hand, the admixture of any other oil is readily discovered, by its causing the disposition to liquescence, even when exposed to severe cold, which distinguishes every other known perfume from genuine _attar_.
