Thus, it is equally clear that the fall in the price has been very considerable since 1845, and that in 1849 and 1850 the price of sugar was about 10s. per cwt., or nearly one-third less than in 1838. The planters complain of the fall of price; and the only question in dispute is whether the fall has been occasioned by the reduction of the duties. Now the reduction of duties subsequent to 1846 and to 1851, was, on brown Muscovado sugar, from 13s. to 10s., or 3s.; and on foreign, from 21s. 7d. to 16s. 4d., or 5s. 3d. At the same time there was a very large increase of consumption, and the price, as of almost all articles, would not have been reduced to the full extent of the reduction of the duties, and certainly not reduced in a much greater degree, had there not been other causes at work to reduce the price. Between 1846 and 1851 freight from the Mauritius fell from £4 1s. 8d. to £2 13s. 9d., or 35 per cent.; and that reduction of price was not made from the planter. In the interval, too, great improvements were made in the manufacture of sugar; and in proportion as the article was produced cheaper, it could be sold cheaper, without any loss to him. I shall now take a separate review of the capabilities and progress of the leading sugar producing countries. _Production in the United States_.--Sugar cultivation, in the United States, is a subject of increasing interest. The demand is rapidly advancing. Its production in the State of Louisiana, to which it is there principally confined, is a source of much wealth. In 1840, the number of slaves employed in sugar culture was 148,890, and the product, 119,947 hhds. of 1,000 lbs. each; besides 600,000 gallons of molasses. Last year, the crop exceeded 240,000 hhds., worth 12,000,000 of dollars. The capital now employed, is 75,000,000 of dollars. The protection afforded by the American tariff, has greatly increased the production of sugar in the United States. From 1816 to 1850, this increase was from 15,000 hhds. to 250,000 hhds. In 1843, the State of Louisiana had 700 plantations, 525 in operation, producing about 90,000 hhds. In 1844, the number of hogsheads was 191,324, and of pounds, 204,913,000; but this was exclusive of the molasses, rated at 9,000,000 gallons. In 1845 there were in Louisiana 2,077 sugar plantations, in 25 parishes; 1,240 sugar houses, 630 steam power, 610 working horse power; and the yield of sugar was 186,650 hhds., or 207,337,000 lbs.
