The better to exhibit the decrease of production throughout the island, I may state that the export from 1839 to 1841 inclusive, was in the aggregate 1,332,221 quintals; 1842 to 1844, inclusive, was in the aggregate 1,217,666 quintals; 1845 to 1847, inclusive, was in the aggregate but 583,208 quintals. The exports of coffee for the whole island, were, in 1840, 2,197,771 arrobas; in 1841, 1,260,920½ arrobas. In 1847 there were 2,064 plantations under cultivation with coffee in Cuba, in 1846 there were only 1,670. The production of 1849 was 1,470,754 arrobas, valued at 2,206,131 dollars. From the year 1841 to 1846, the average yearly production was 45,236,100 lbs.; but from 1846 to 1851, it was only 19,206,100 lbs.; showing a falling off of 72 per cent.; the production still further decreased in 1851, it being only 13,004,350 lbs., or 1.52 per cent. less than the preceding year. This enormous decline in the production of coffee has been caused by the low price of the article in the markets of Europe and the United States, coupled with the more remunerative price of sugar, during the same period; causing capitalists rather to invest money in the formation of new sugar estates. As a consequence, many coffee plantations have been turned into cane cultivation; or, being abandoned, the slaves attached thereto were sold or leased to sugar planters. The following is private information from a correspondent:-- "We generally plant about 200,000 trees within a space of 500 feet, choosing the strongest soil. I have adopted a different system from the one generally in use here, for they usually plant the trees too near each other. I find by giving them space and air, that the plant develops itself and yields more beans. It is very important to protect the trees from the rays of the sun, for which purpose I plant bananas at intermediate rows; their broad leaves, like parasols, shed a delightful shade round the coffee plant, and tend to accumulate the moisture which strengthens the roots of the young tree. When the tree is about two years old the top branches are lopped off for the purpose of throwing the sap into the bean. Some planters cut the trees so short, that they do not allow them to stand more than five or six feet above the ground; but I allow mine to attain greater height prior to lopping them, whereby they produce larger crops. Nor do I allow my negroes to beat the trees, or force them to pluck a certain quantity a day, for I discovered that they picked the ripe and unripe beans indiscriminately--frequently injuring the trees. I only allow them to shake the tree, and pick up the beans that have fallen during the night." Coffee exports from the ports of Havana and Matanzas, in Cuba, for the years ending December in
