The _Westminster Review_ has said, 'The Americans are planting free negroes on the coast of Africa; a greater event, probably, in its consequences, than any that has occurred since Columbus set sail for the New World.' Let us now adopt gradual emancipation, and the colonization of Africa, and the voyage of the great discoverer will have given civilization and Christianity to two continents, and eventually, we trust, the blessings of liberty to all mankind. The divers products and fabrics of Africa and of our Union invite reciprocal commerce. We want her gold, coffee, ivory, dyestuffs, and numerous raw materials of manufactures; and she wishes our fabrics, engines, agricultural implements, breadstuffs, and provisions. The trade will give immense and profitable employment to our shipping. From the Cape of Good Hope to the Mediterranean, from the Atlantic to the Red sea and the Indian ocean, Africa is tropical or semi-tropical. She has most of the products of the East and West Indies. She can produce cheaper and better cotton than any other region, except our Southern States, to which, from their fertile soil, and climate favored by the Gulf Stream, free white labor will eventually give us, substantially, a monopoly of that great staple. She equals any country in the production of sugar, coffee, and cocoa. In palm oil and ivory she has almost a monopoly. Of spices, she has the clove, nutmeg, pepper, and cinnamon. Of dyes and dyewoods, she has indigo, camwood, harwood, and the materials for the best blue, brown, red, and yellow colors. In nuts, she has the palm, the ground, the cocoa, and the castor. In gums, she has the copal, senegal, mastic, India rubber, and gutta percha. In fruits, she has the orange, lime, lemon, citron, tamarind, papaw, banana, fig, grape, date, pineapple, guava, and plantain. In vegetables, she has the yam, cassado, tan yan, and sweet potato. She has beeswax and honey, and most valuable skins and furs. In woods, she has the ebony, mangrove, silver tree, teak, unevah, lignumvitae, rosewood, and mahogany. She has birds with the sweetest notes and brightest plumage, and fish and animals in the greatest variety. There are the giant elephant, rhinoceros, and hippopotamus. There the lordly lion roams, the monarch of his native forest, as if conscious of furnishing robes for royalty and symbolizing the flag of a great nation. Where animals of such sagacity, courage, power, and majesty are found, why should not man be great also? Our ancestors, the Britons, were once savages; so were our Celtic and Saxon forefathers, and most of them were slaves. What are their descendants now? Let Shakespeare, Newton, Fox, Burke, Pitt, Peel, Washington, Wellington, Franklin and Hamilton, Madison and Jefferson, the Adamses, Webster, Clay, and Jackson answer the question. I am hopeful of complete success; but whatever the result may be, we owe to ourselves, to our moral and material progress, but, above all, to the down-trodden race so
