_Trinidad_.--The coffee plant does not succeed well in Trinidad, the tree giving but little fruit, and perishing at the end of ten or twelve years; though the article is always of a superior quality, and has the advantage over that of Martinique and the other Antilles of not requiring age to produce an agreeable beverage. It is from the fault and obstinate attachment to old habits of the planters, that this cultivation has not been more successful in Trinidad. Because coffee trees thrive in St. Domingo, Guadalupe, Dominica, St. Lucia and Martinique, on the hills, they had concluded that it would be the same in Trinidad; without noticing that the hills of that island are composed only of schistus covered with gravel, on which lies a light layer of vegetative earth, that the rain washes away after some years of cultivation; whilst the hills of the Antilles, much more high and cool, are covered with a deep bed of earth, which is retained by enormous blocks of stone, that at the same time maintain humidity and freshness. Messrs. Branbrun, of Tacarigua, and Don Juan de Arestimuno, of Cariaco, worthy and intelligent planters, some years ago adopted the plan of planting coffee trees on the plains, in the manner cacao trees are planted, that is, in the shade of the _Erythrina_, and this mode of cultivation has perfectly succeeded. It is to be hoped that their success will encourage the cultivation of this valuable tree in the united provinces of Venezuela, and in those parts of Trinidad which were deemed unfavorable to it from the too great dryness of the climate. In 1796, the year preceding its capture, there were 130 coffee plantations in Trinidad, which produced 330,000 lbs. of coffee. In 1802, the produce had slightly increased to 358,660 lbs., but there were two plantations less. In the island of Grenada, according to the returns made to the local Treasury of the staple products raised, while there were 64,654 lbs. made-in 1829, the quantity had decreased to 13,651 lbs. in 1837. The colony of British Guiana was formerly noted for its produce of coffee. The following figures mark the decline of the culture of this staple, showing the exports in Dutch pounds:-- Demerara and Essequibo. Berbice. 1834 1,102,200 1,429,800 1835 1,299,080 1,979,850 1836 2,117,250 2,684,100 1837 1,849,650 2,217,300 1838 2,486,240 1,700,550 1839 747,450 1,255,800 1840 1,531,350 1,825,950 1841 568,920 519,750 1842 1,372,650 804,470 1843 428,800 999,300 1844 716,137 774,600 Thus the exports of the colony which in 1836 were 4,801,350 lbs. had declined in 1844 to 1,490,737; whilst in 1831 we received from British Guiana 3,576,754 lbs. of coffee, in 1850 we only received 8,472 lbs.
