tation, vast fortunes will reward those who may be the pioneers 

 of commerce ; but the first stej) necessary toward, this is the es- 

 tablishment of proper means of communication. 



Africa for some time to come will lack a sufficiency of labor 

 to carry on the necessary mining and agricultural operations, 

 and to supply men for making roads. But this will prove by 

 no means an unmixed evil ; for when the chiefs find it more 

 profitable to employ their subjects in their own country than 

 to sell them as slaves, they will lose the most powerful incentive 

 toward complying with the demands of the slave-dealer, 

 ■ An enumeration of some of the products which may form val- 

 uable articles of trade, and the localities in which they are found, 

 will assist in giving an idea of the great wealth of the country. 



The vegetable products are — 



Sugar-canes, which flourish wherever there is sufficient moist- 

 ure. 



Cotton, cultivated almost everywhere, and grows wild in 

 Ufipa and some other countries. 



OU-palm flourishes in marvelous profusion to a height of 

 two thousand six hundred feet above the sea, all along the broad 

 valley of the Lualaba, and in some places to a height of three 

 thousand feet. This palm also grows on the island of Pemba. 

 and might doubtless be cultivated with advantage on the East 

 Coast. 



Coffee grows wild in Karagweh and to the west of ISTyan 

 gwe. The berry of Karagweh coffee is said to be small ; but 

 that of the plant near Nyangwe is as large as the Mocha bean, 

 which it greatly resembles in appearance. 



Tobacco is grown almost throughout the continent, and in 

 some places is of very excellent cjuality. Ujiji excels in this 

 respect ; the leaf being smooth and silky, like that of the best 

 Cuban plants. 



Sesamum flourishes on the East Coast, near Zanzibar, from 

 which place large quantities are exported to France, " the finest 

 olive-oil" being made from it at Marseilles. It also grows in 

 Unyamwezi, near the Tanganyika, and in Urua, and its culti- 

 vation might be indefinitely extended. 



The Castor - oil ])lant. — Two varieties are met with every- 

 where, sometimes cultivated and sometimes growing wild.
