I did not leave Seville without visiting the snuff manufactory--the most celebrated in Spain. The building in which the manufacture is carried on, is more like a fortified palace, than a house destined for the preparation of tobacco. It has four regular fronts; two of them six hundred feet long--the other two, four hundred and eighty feet. This manufactory is sadly on the decline; in other times, the complement of men and women used to exceed three thousand, and upwards of three hundred mules and horses were employed; forty years ago, that number was reduced to one thousand seven hundred workmen, and a hundred mules. When I visited it, no more than four hundred men were employed, and eleven mules; and in place of two hundred grind-stones, which formerly were constantly at work, four only were in requisition. This falling off is to be attributed partly to the extensive contraband trade carried on through the free ports of Gibraltar and Cadiz; and partly to the high price which government puts upon the manufactured article. The stock on hand at present exceeds two millions of arobas (fifty millions of pounds); forty years ago, the stock on hand amounted to five millions of pounds; of the snuff at present on hand, there are eight thousand canisters fifty years old. It is not likely, according to the present policy of the government, that this stock will diminish; the price was only lately raised from thirty-two to forty-eight reals, and the demand has constantly diminished. I have been speaking of what is called Seville snuff; there is another department, for the manufacture of rappee, which is now more in vogue, and does not accumulate in the same ratio as the other. Government derives a profit upon the manufacture and sale, of seventy per cent. before paying the expenses of the establishment. The workmen employed are paid six, seven, and eight reals per day, according to their ability--those who twist cigars, work by the piece. It happened to be the hour of dismissal when I visited the establishment, and I noticed that each workman was taken into a little inclosed place, and underwent a rigorous search; they were even obliged to take off their shoes. Most of the workmen looked unhealthy. I learned that during the heats of summer, as many as twelve are sometimes carried to the hospital in a day; and that they almost invariably die of disease in the lungs at an early age.
