That night Rachel felt too exhausted to sleep, though why this should be she could not guess, as she had done nothing all day save watch the mutes at their dreary tasks, and it was strange, therefore, that she should feel as though she had made a long journey upon her feet. About an hour before the dawn she saw Nya rise and glide past her towards the mouth of the cave, carrying in her hand a little drum, like those used by the mute women. Something impelled her to follow, and waking Noie at her side, she bade her come also.

Outside of the cave by the faint starlight they saw the little shape of Nya creeping down the mound, and thence across the open space towards the wall, and went after her, thinking that she intended to pass the wall. But this she did not do, for when she came to its foot Nya, notwithstanding her feebleness, began to climb the rough stones as actively as any cat, and though their ascent seemed perilous enough, reached the crest of the wall sixty feet above in safety, and there sat herself down. Next they heard her beating upon the drum she bore, single strokes always, but some of them slow, and some rapid, with a pause between every five or ten strokes, “as though she were spelling out words,” thought Rachel.

After a while Nya ceased her beating, and in the utter silence of the night, which was broken only, as always, by the occasional crash of falling trees, for no breath of air stirred, and all the beasts of prey had sought their lairs before light came, both she and Noie seemed to hear, far, infinitely far away, the faint beat of an answering drum. It would appear that Nya heard it also, for she struck a single note upon hers as though in acknowledgement, after which the distant beating went on, paused as though for a reply from some other unheard drum, and again from time to time went on, perhaps repeating that reply.

For a long while this continued until the sky began to grow grey indeed, when Nya beat for several minutes and was answered by a single, far-off note. Then glancing at the heavens she prepared to descend the wall, while Rachel and Noie slipped back to the cave and feigned to be asleep. Soon she entered, and stood over them shaking her grey head and asking how it came about that they thought that she, the Mother of the Trees, should be so easily deceived.

“So thou sawest us,” said Rachel, trying not to look ashamed.

“No; I saw you not with my eyes, either of you, but I felt both of you following me, and heard in my heart what you were whispering to each other. Well, Inkosazana, art thou the wiser for this journey?”

“No, Mother, but tell us if thou wilt what thou wast beating on that drum.”

“Gladly,” she answered. “I was sending certain orders to the slave peoples who still know me as Mother of the Trees, and obey my words. Perhaps thou dost not believe that while I sat upon yonder wall I talked across the desert to the chiefs of the marches upon the far border of the land of the Umkulu, and that by now at my bidding they have sent out men upon an errand of mine.”

“What was the errand, Mother?” asked Rachel curiously.

“I said the errand was mine, not thine, Maiden. It is not pressing, but as I do not know how long my strength will last, I thought it well that it should be settled.” Then without more words she coiled herself up on her mat and seemed to go to sleep.
