Mauritius.—­In the year 1813 the exports of sugar from this island were but 549,465 lbs., and increasing gradually to 128,476,547 lbs. in 1849, or two-hundred fold in thirty-six years.

The equalisation of the duties in 1825, and the admission of Mauritius sugars into England on the same footing as those from the West Indies, had the effect of stimulating the sugar trade of Mauritius, and advancing it to its present remarkable success.  Notwithstanding its immense crops, scarcely more than three-fifths of the island is yet under cultivation; but it has the advantage of a cheap and abundant supply of labor, and much improved machinery has been introduced.  The planters first commenced introducing Coolies in 1835, and were for some time restricted to the single port of Calcutta for their supply.

The recent advices from Mauritius furnish some interesting information regarding the progress making in the sugar production of that colony.  In reference to the cultivation of the cane, it is stated that by the introduction of guano upon several estates in the interior, the production has been very largely increased; but as the value and economy of manure has not been hitherto sufficiently estimated, its introduction has not been so general as could be desired.  The importance of free labor to the cultivation of the estates, has now become fully appreciated by the planters; it being found that an equal amount of work can be obtained by this means from a less number of hands, and that at lower rates of wages than were current in previous years, the average of which is shown in the following table:—­
