this gentleman’s _Monthly Colonial Circular_, dated March the 18th, in which I observe a considerable increase in the exports of plain calicoes, printed and dyed calicoes, and cotton yarn to the following markets, with a few exceptions, for the first two months of the present year:—Calcutta, Bombay (increase in printed and dyed and in yarn, and small decrease in plain only); Madras (considerable increase in plain and printed and dyed, and small decrease in yarn); Singapore and Manilla (small decrease in printed and dyed and in yarn only); Batavia (large increase in all kinds); Hong Kong and Canton (large increase in plain, and small decline in printed); Shanghae (trade removed to other Chinese ports in which there is a large increase): Australian Colonies (increase in all kinds); Mauritius (stationary); Cape of Good Hope (increase in all); Coast of Africa (decline in all); Jamaica (decrease in plain and increase in printed); Honduras (increase); other West Indian ports (decrease); Cuba and St Thomas (both increase); French West Indies (increase in printed and small decline in plain); Brazils (large increase); Chili and Peru (large decrease); Colombia (decrease); River Plata (considerable decrease); Mexico (increase in plain, and decrease in printed); British North America (season for shipments not commenced); and United States (increase in both printed and plain, and a large business done, the shipments for the two months being upwards of half of the entire quantity exported in 1849.) Compared with the average of the same period of the preceding three years, there is an increase to nearly every market. With respect to the shipments to European markets, I cannot speak with precision as to quantities, from the circumstance, which I have named, of the accounts not having been yet made up. From the monthly return from the Board of Trade, however, it appears that a general increase has taken place in the declared value of cotton manufactures to all markets, the amount being in 1850, £3,264,350 for the two months, against £2,837,300 last year. There is a very trifling decline in the export of yarns. From my own observation, I should augur that the increase has extended over March, to the United States and the markets of the Pacific especially—an unusual stimulus having been given to the consumption of these markets by the Californian discoveries. By the bye, I ought to mention, in connexion with the increase in the declared value of our exports this year, the fact that, owing to the advance in the price of the raw material, the value of goods exported will be rated higher than last year. To some extent, however, the severe winter of this year preventing the early opening of the navigation of the rivers of the north of Europe, as compared with the mild season last year, may be a set-off. The Mediterranean trade, and the operations of the Greek houses, have also been limited by our petty quarrel in this part of Europe.
