The philanthropist having at last obtained such signal success with the Prince, it is time the merchant should attempt something with him. The Prince must be considered as an independent sovereign. His territories include, besides the Zanzibar, Pemba, and Mafia islands, nearly 1000 miles of coast, and extend probably over an area of 20,000 square miles, with a population of half a million. The products of Zanzibar have enriched many Europeans who traded in them. Cloves, cinnamon, tortoise-shell, pepper, copal gum, ivory, orchilla weed, indiarubber, and hides have been exported for years; but this catalogue does not indicate a tithe of what might be produced by the judicious investment of capital. Those intending to engage in commercial enterprise would do well to study works on Mauritius, Natal, and the Portuguese territories, if they wish to understand what these fine, fertile lands are capable of. The cocoa-nut palm flourishes at Zanzibar and on the mainland, the oil palm thrives luxuriantly in Pemba, and sugar-cane will grow everywhere. Caoutchouc remains undeveloped in the maritime belts of woodland, and the acacia forests, with their wealth of gums, are nearly untouched. Rice is sown on the Rufiji banks, and yields abundantly; cotton would thrive in any of the rich river bottoms; and then there are, besides, the grains, millet, Indian corn, and many others, the cultivation of which, though only in a languid way, the natives understand. The cattle, coffee, and goats of the interior await also the energetic man of capital and the commercial genius. First, however, the capitalist must find means of carriage, otherwise he will never conquer African difficulties. Cutting roads through jungles, and employing waggons, are mere temporary conveniences, requiring great outlay, patience, and constant reinforcement of work and energies. Almost as fast as the land is cleared, it is covered again—so prolific is the soil—with tall wild grasses of the thickness of cane, and one season is sufficient to undo the work of months of the pioneer. Cattle die, tormented out of life by the flies or poisoned by the rank grasses; natives perish from want of proper nourishment, and, while suffering from fatigue and debility, are subject to many fatal diseases. A tramway is one thing that is needed for Africa. All other benefits that can be conferred by contact with civilisation will follow in the wake of the tramway, which will be an iron bond, never to be again broken, between Africa and the more favoured continents.
