An attack or razzia, such as described, generally leads to a quarrel with the negro ally, who in his turn is murdered and plundered by the trader–his women and children naturally becoming slaves.

A good season for a party of a hundred and fifty men should produce about two hundred cantars (20,000 lbs.) of ivory, valued at Khartoum at 4,000 pounds. The men being paid in slaves, the wages should be NIL, and there should be a surplus of four or five hundred slaves for the trader’s own profit–worth on an average five to six pounds each.

The amiable trader returns from the White Nile to Khartoum; hands over to his creditor sufficient ivory to liquidate the original loan of 1,000 pounds, and, already a man of capital, he commences as an independent trader.

Such was the White Nile trade when I prepared to start from Khartoum on my expedition to the Nile sources. Every one in Khartoum, with the exception of a few Europeans, was in favor of the slave-trade, and looked with jealous eyes upon a stranger venturing within the precincts of their holy land–a land sacred to slavery and to every abomination and villainy that man can commit.
