The stone formation throughout these regions consist of primitive dark-gray granite, quartz, and conglomerates, with, occasionally, strata of felspar and mica, which are found mainly in the beautiful mountain regions (which are detailed extensions of the great mountains of Kong), having in these sections always beautiful gaps or passes of delightful valleys. Minerals, Iron, Copper, Zinc The minerals consist of iron in the greatest abundance, which at present is smelted by the natives from the clay, and every town of any note or size has not only its blacksmiths' shops, but the largest all have iron smelting works. At Ijaye there is quite an extensive and interesting establishment of the kind. And, as they manufacture _brass_, there must be also zinc and copper found there--indications of the last-named metal being often seen by the color of certain little water surfaces. The stone formation bears the usual indications of aqueous and igneous deposits, but more of the former than the latter. Productions Timber The timber is numerous, and for the following classification I am indebted to my learned friend the Rev. Alexander Crummell, Episcopal missionary and Principal of the Mount Vaughn High School at Cape Palmas: Teak, ebony, lignum vitae, mahogany, brimstone, rosewood, walnut, hickory, oak, cedar, unevah, and mangrove. Medical Productions Gum Yoruba (the same as gum Arabic), acacia or senna, castor oil, croton oil, rhubarb root, colomba-root, ipecacuanha, quasia, nux-vomica, cubebs, tobacco, and many others. Fruits All the fruits common to the tropics are found in these regions; in fact, so redundant is Africa with these productions, that she combines the whole within herself; that is, there are some fruits found in the tropical parts of Asia, South America, the Asiatic and West India Islands, common or peculiar to one which may not be found in the other, but all of which, it may safely be said, can be found in Africa. Pineapples the most delicious in flavor and taste conceivable oranges the same, bananas the finest, plantains equally so, mangrove plums (a peculiar but delightful and wholesome fruit, said by the natives to be a _febrifuge_), guavas, and "soursops," a delightful _febrifuge_ of pure _citric acid_, without the least acridness, as well as a hundred others which I cannot now name. The papaw or tree-melon also grows very finely here, and is a very useful and wholesome fruit. When green, "stewed and mashed," and well-flavored with the usual culinary spices, it cannot be distinguished from the best green apple-sauce--for which reason it makes excellent pies. When fully ripe, it cannot be told from the finest muskmelon or cantelope. Agricultural Products
