These barbarians now, humming a bass war-song as they march, are in high glee, for there are more villages to raid. And as the whole party moves forth from the glade once more to plunge within the forest gloom, the air is alive with the circling of carrion birds; and the newly risen sun darts his first arrowy beam upon the scene of horror, lighting up the red gore and the slain corpses, and the ghastly staring heads upon the gateway. Even as his last ray fell upon a tragedy of blood and of cruelty so now does his first, for in truth this is one of the "dark places of the earth." CHAPTER XIII. THE MAN HUNTERS. For some three hours the party moves forward through the forest shades. Then a halt is called, and, sentinels having been posted, soon the smoke of bivouac fires ascends, and the clatter of cooking utensils mingles with the hum of many voices. The place selected is an open glade or clearing, overhung on one side by hoary masses of rock. The slave-hunters, as we have said, are divided into two sections, one consisting of negroid Arabs and Wa-Swahili, believers in the Prophet mostly, and clad in array once gaudy but now soiled and tarnished, some few, however, wearing the white haik and burnous; the other of Wangoni, stalwart, martial savages, believers in nothing and clad in not much more. These form camps apart, for at heart each section despises the other, though for purposes of self-interest temporarily welded. A few, but very few, are Arabs of pure blood. One of these is now engaged in converse with the leader of the party. He is a tall, dignified, keen-faced man, with eyes as piercing as those of a hawk, and his speech is sparing. But if his words are few his deeds are many, and the name of Lutali--which, however, he makes no secret is not his real name--is known and feared at least as far and as thoroughly as that of the chief of the slavers himself. For the latter, one glance at him is sufficient to show that if ever man was born to rule with firm but judicious hand such a gang of bloodthirsty freebooters it is this one. The vigour of his powerful frame is apparent with every movement, and the strength and fixity of will expressed in his keen dark face there is no mistaking. But the black, piercing eyes and bronzed features belong to no Arab, no half caste. He is a white man, a European.
