The quality of coffee grown in the republic of Liberia, on the western coast of Africa, is pronounced by competent judges to be equal to any in the world. In numerous instances, trees full of coffee, are seen at only three years old. 214 casks and bags of coffee were imported from the western coast of Africa in 1846. Coffee, it has been proved, can be cultivated with great ease to any extent in the republic of Liberia, being indigenous to the soil, and found in great abundance. It bears fruit from thirty to forty years, and yields 10 lbs. to the shrub yearly! A single tree in the garden of Colonel Hicks, a colonist at Monrovia, is said to have yielded the enormous quantity of 16 lbs. at one gathering. Judge Benson, in 1850, had brought 25 acres under cultivation, and many others had also devoted themselves to raising coffee. It was estimated there were about 30,000 coffee trees planted in one of the counties, that of Grand Bassa, and the quality of the produce was stated to be equal to the best Java. About the villages and settlements of the Sherbro river, and Sierra Leone, wild coffee-trees are very abundant. In several parts of the interior, the natives make use of the shrub to fence their plantations. Coffee has been successfully grown at St. Helena, of an excellent quality, and might be made an article of export. Portugal sent to the Great Exhibition, in 1851, a very valuable series of coffees from many of her colonies; of ordinary description from St. Thomas; tolerably good from the Cape de Verd islands; bad from Timor; worse (but curious from the very small size of the berry) from Mozambique; good from Angola; and excellent from Madeira. Aden, alias Mocha coffee, is, along with the other coffees of the Red Sea, sent first to Bombay by Arab ships, where it is "garbelled," or picked, previously to its being exported to England. An excellent sample of coffee, apparently of the Barbera (Abyssinia) variety, was contributed to the Great Exhibition from Norfolk Island. It was of good color, well adapted for roasting, and a most desirable novelty from that quarter.
