Discoveries and conquests, which so frequently go hand in hand, are of the greatest importance to the history of mankind. Like a combination of streams, they break through natural boundaries and the rocky dams of ages, and open a way for the incessant progress of civilization through new and untrodden paths. Yet glorious enterprises, costly equipments, and hazardous exploits, may conceal a swelling kernel of material interest beneath a husk of fine reasons, as if these constituted the primitive motive. Thus Mohammed Ali, the Viceroy of Egypt, has done very much for science, especially geography, without even thinking of it, whose comprehensive relations, with respect to the higher requirements of mankind, lie far beyond the limits of his ideas. Neither has he honoured with his study the hieroglyphics in the Biban el Moluk near Thebes, where the black Kushi bring golden rings as tribute to the Pharaohs. Yet he knows, and is so exceedingly fond of these rings (Okiën), which in Ethiopia even now serve instead of money, that, so far as the destroying arms of this much-famed satrap reach in Belled-Sudan, no more okiën are to be seen. Moreover, he is making exertions to follow and secure those that have retreated and eluded his grasp, which affords an excellent opportunity for extending our knowledge of the countries and people of East and Central Africa. He sacrificed his son Ismail, and, through the Defterdar, devastated and depopulated this beautiful country, merely to secure to himself the way to the gold regions; though he might have attained his object much better, had he sought to elevate the country in every possible way, and to re-establish mercantile confidence. For, from the earliest ages, a market has existed here, to which gold comes, first hand, in the leaf and grain form, by barter with the inhabitants of the interior, just as it has been separated from the sand of the torrents, and kept in quills or horns of the gazelle. In Sennaar or Kordofan it is found in rings of half and whole okiën and in gold wire, but it is frequently changed, by weighing and melting it down, into ingots or bars, which Mohammed Ali just as little contemns.
