It is but a few years ago that the wool of the Buenos Ayrean sheep was hardly worth the expense of cleaning it; and as to the meat, I doubt whether the wild dogs would have touched it. It is well known that their carcases, dried in the sun, were used for fuel in the brick-kilns. The great pains and persevering exertions, however, of some intelligent foreigners to introduce and cultivate a better breed has met with a success beyond all expectation, and now promises to be of the greatest importance to the future commercial prospects of the country. The rapid increase in the value of this article of production will be shown by the following comparative account of the quantities which have been imported into Great Britain alone in the last eight years:-- Imports of Wool from Buenos Ayres. lbs. 1830 19,444 } 1831 12,244 } 269,190 lbs. 1832 30,359 } 1833 207,143 } 1834 1,099,052 } 1835[79] 962,900 } 5,343,319 lbs. 1836 1,073,416 } 1837 2,207,951 } Mr. Sheridan and Mr. Harratt are the individuals to whom Buenos Ayres is principally indebted for this new source of wealth: the greater part of the wool sent to England in 1834 was of their production, and sold at Liverpool at very high prices compared with those obtained for the old native wools of the country, the quality of which comes perhaps nearest to the low Scotch wools, and is only suited for carpeting, and other strong descriptions of goods. In a country where any quantity of land applicable for the purpose may be had almost for nothing, it is impossible to calculate to what extent the breeding and improvement of sheep may be carried, now that the wool is known to fetch a remunerating price in foreign markets. Nor is wool the only raw material for our manufactures which we may expect to derive from Buenos Ayres. In my notices of the interior I have stated that in Paraguay and some of the Upper Provinces, especially Corrientes, cotton of a quality equal to the average of that of Brazil is produced:--this has been often satisfactorily shown by samples sent to Liverpool. The natives cultivate it and make cloths of it for their own domestic purposes; and we shall probably obtain large quantities of it whenever foreigners shall enjoy such security as may induce them to carry into the interior the machinery necessary to clean and pack it for the markets of Europe.
