I have heard the traders of Khartoum pretend that they can distinguish the tribes of the White Nile by their individual type. I must confess my inability on this point. In vain I have attempted to trace an actual difference. To me the only distinguishing mark between the tribes bordering the White River is a peculiarity in either dressing the hair, or in ornament. The difference of general appearance caused by a variety of hairdressing is most perplexing, and is apt to mislead a traveller who is only a superficial observer; but from the commencement of the negro tribes in N. lat. 12 degrees to Ellyria in lat. 4 degrees 30 minutes I have found no specific difference in the people. The actual change takes place suddenly on arrival in Latooka, and this is accounted for by an admixture with the Gallas. The Latookas are a fine, frank, and warlike race. Far from being the morose set of savages that I had hitherto seen, they were excessively merry, and always ready for either a laugh or a fight. The town of Tarrangolle contained about three thousand houses, and was not only surrounded by iron-wood palisades, but every house was individually fortified by a little stockaded courtyard. The cattle were kept in large kraals in various parts of the town, and were most carefully attended to, fires being lit every night to protect them from flies; and high platforms, in three tiers, were erected in many places, upon which sentinels watched both day and night to give the alarm in case of danger. The cattle are the wealth of the country, and so rich are the Latookas in oxen, that ten or twelve thousand head are housed in every large town; thus the natives are ever on the watch, fearing the attacks of the adjacent tribes.
