Cane Sugar. Beet-root. Totals. Tons. Tons. Tons. 1848 60,500 26,000 86,500 1849 54,000 34,000 88,000 1851 45,000 43,000 88,000 Thus we find that in the period of four years cane sugar has lost 15,000 tons and it will lose still more when new manufactories shall have been established. The consumption of Russia is estimated at 85,000 tons, of which 35,000 is beet-root, and what proves that the latter every day gains ground is, that the orders to the Havana are constantly decreasing, and prices are getting lower. In 1848 Austria consumed 40,000 tons, of which 8,000 were beet-root. Last year (1851,) she produced 15,000 tons. The production of the continent rising to 200,000 tons, and the consumption remaining nearly stationary, it is evident that Brazilian and Cuban sugars will encumber the English market, independently of the refined sugar of Java, which Holland sends to Great Britain. When the continental system was established by the decrees of Milan and Berlin, the Emperor Napoleon asked the savans to point out the means of replacing the productions which he proscribed: it is to the active and useful impulse which his genius impressed on all minds, that France and Europe owe this fresh manufacture--a creation the more valuable as its fortunate development required the co-operation of chemical science and agricultural improvement." The quantity of sugar extracted from beet-root in the commencement of the process, amounted to only 2 per cent.; but it was afterwards made to yield 5 per cent., and it was then supposed possible to extract 6 per cent. On this calculation the fiscal regulations for the protection of colonial sugars in France were founded; but recent experiments have been made, by means of which as much as ten and a half per cent. of sugar has been obtained. The following notice of the improved process is given in a number of the _Constitutionnel_:--
