Mpuke is so tired he can hardly keep his eyes open. He drags himself into the hut where his sister lies on her mat, already sound asleep. Listen! what is that scuttling noise among the dried leaves in the corner? Mpuke's bright black eyes are helped by the moonlight streaming through the doorway. He discovers that it is a green lizard, which he knows to be quite harmless. But it is always wise to be watchful.

One night, not many moons ago, as the black boy counts time, he found a centipede close to his bare feet when he woke up suddenly in the night. He is quite sure that a good spirit roused him to save his life.

At another time a lizard of the most deadly kind must have shared the boy's mat with him through the night. At any rate, he found the lizard at his side when his eyes opened to the morning light.

But Mpuke is too sleepy to think about unpleasant things, and in another moment he is dreaming of the roasted elephant that will make to-morrow's feast.

A week passes by. We will visit Mpuke once more as he is eating his early breakfast.

A messenger from the next village comes rushing in to the people. He has run ten miles this morning through the forest paths, and has brought word to Mpuke's father from his own chief. The two men are blood-brothers, and have promised to stand by each other in all troubles and dangers. "Blood-brothers," you say, "what does that mean?" When the chiefs were only boys they went through a sacred ceremony together. An arm of each was cut till the blood ran, then the two arms were pressed together, and the blood was allowed to mingle.

They must never quarrel again. No cruel words or deeds should ever pass between them, because they are now bound together by the strongest of all ties.

But what is the message that causes such a state of excitement? It tells that enemies are approaching. It means war, and preparation for awful deeds. Mpuke's father is asked to come to the help of his blood-brother. Will he join him to meet the advancing foes?

There is only one answer possible; not a moment must be lost. The order is given to sound the war-drums; the people burst into an exciting battle-song; blasts from ivory trumpets can be heard throughout the village; the men cover their faces with charcoal and hastily seek the medicine-man. He must provide them with charms to protect them from danger. Poor fellow, he is the busiest one of all the people, making little packages of beads, shells, and stones for each soldier to wear as a talisman.

The women are at work getting the spears and arrows together; they must also sharpen the knives for their husbands and sons.
