separates the chaff from the beans, and subsequently the beans are passed through copper sieves to separate the perfect from the broken coffee, and finally handpicked and put into bags or casks for shipment. BRITISH GUIANA.--Coffee was for a length of time almost the only staple of Berbice and Demerara, but the cultivation of the sugar-cane has been substituted for it. The quantity of coffee, the produce of British Guiana, exported in 1830 was, 9,472,756 lbs.; in 1840, 3,357,300 lbs.; in 1849, 100,550 lbs.; and in 1850, 30,000 lbs.; since which it has almost ceased to be exported, scarcely sufficient being produced to supply the demand in the colony. At one time there were about two hundred coffee plantations in the small island of DOMINICA, and four to five million of pounds of coffee were exported annually to Great Britain. PORTO RICO.--In proportion to its extent, this island is twice as productive as Cuba, and the quality of its coffee and other produce is of the highest class. There were, in 1862, fifty-three coffee plantations on the island, producing about 100,000 cwt. of coffee. The exports of coffee were, in lbs. 1855 11,506,283 1856 9,935,000 1857 8,245,000 1858 9,814,000 1859 13,457,000 The exports of coffee from the island of CUBA, which were in 1840 upwards of 2,000,000 arrobas, were in 1858 but 21,000; and in 1859, 5000 or 6000. BRAZIL.--The coffee-plant has been known in Brazil for many years; it is but about fifty years, however, since the first regular plantation was made by Mr. Moke, a Belgian, who brought the cultivation of coffee to great perfection. His plantation is still in the neighbourhood of the capital, and is carried on by his son with much success. It is astonishing to what an extent coffee has been cultivated since Mr. Moke first made his plantation. Two millions of bags of 160 lbs. each are annually exported from Rio de Janeiro, taking the average of the last seven years; 1862 was, however, short of this about half a million bags. At Barahyba do Sul, which is within a few miles of Rio, there are plantations employing six and seven hundred slaves.
