till it was overthrown by some more powerful league.

All this was unheeded by the outer world, from which the Soudan is
separated by the deserts, and it seemed that the slow, painful course of
development would be unaided and uninterrupted. But at last the
populations of Europe changed. Another civilisation reared itself above
the ruins of Roman triumph and Mohammedan aspiration--a civilisation

The black aboriginals were silent and afraid. The whole vast territory
was conquered with very little fighting, and the victorious army,
leaving garrisons, returned in triumph to the Delta.

What enterprise that an enlightened community may attempt is more

seeds of commerce and learning, to increase in whole peoples their
capacities for pleasure and diminish their chances of pain--what more
beautiful ideal or more valuable reward can inspire human effort? The
act is virtuous, the exercise invigorating, and the result often
extremely profitable. Yet as the mind turns from the wonderful cloudland
