Tahara Among African Tribes

What's the matter, Raal? You seem to be worried about something. Dick Oakwood, blue eyed and smiling and resembling a blond savage in his garb of soft zebra skin, glanced down at his chief warrior who prostrated himself at the feet of the boy king.
Tahara, hal! Come quickly, O Master! replied Raal, his whole body expressing fear.
What is it, Raal? What new danger threatens us now? asked Dick, dropping the work he was doing and facing the stocky figure of the warrior.
Tahara is great! I do not fear, replied Raal still bowing low before the boy, but his trembling shoulders and terror-stricken eyes told Dick that something unusual had happened.
Dick Oakwood cast a glance about the royal enclosure, a spring surrounded by date palms, then strained his eyes toward the vast expanse of the Sahara. Everything was quiet. It was mid-afternoon and the savages went about their work in drowsy fashion still only half awakened from their siesta, the resting time while the blazing sun was at its height. The women were in their caves, busy with the weaving and spinning. The tribesmen of the kingdom of Tahara were in the fields, cultivating the ground while others were chipping flint arrowheads and making bows and spears. There was no sign of trouble anywhere.
Dick turned to Raal. Speak, Raal, what bothers you?
O Master, gasped the chief warrior, nervously gripping his stone hatchet. Near the spot where the great bird-demon rested a few suns ago, a strange object with terrible staring eyes, is lying in the sand. It is an evil spirit, I am sure.
Bring it here, Raal. I would see what it is.
Raal started violently as if struck, his tanned face turned pale. I dare not, O Tahara! It is perhaps black magic! It may work evil. I beg of you, Tahara, take your bow and drive an arrow through this demon's heart before it slays us.
Come with me, Raal! commanded Dick. Show me this strange creature! How big is it? As big as a leopard?
No master it is very small, but terrible, and its skin is black and shiny. In truth it is a wicked demon.
