So they ran forward, all three of them, seeing and hearing nothing of the shooter of the arrow. As they approached the titanic wall they saw that it enclosed a mound, on the top of which mound grew a cedar-like tree with branches so wide that they seemed to overshadow half of the enclosure. There were no gates to this wall, but while they wondered how it could be entered, Nya led them to a kind of cleft in its stones, not more than two feet in width, across which cleft were stretched strings of plaited grass. She pressed herself against them, breaking them, and walked forward, followed by Rachel and Noie. Suddenly they heard a noise above them, and, looking up, saw white-robed dwarfs perched upon the stones of the cleft, holding bent bows in their hands, whereof the arrows were pointed at their breasts. Nya halted, beckoning to them, whereon, recognising her, they dropped the arrows into the little quivers which they wore, and scrambled off, whither Rachel could not see. “These are the guardians of the Temple that cannot either speak or hear, who were summoned by the breaking of the thread,” said Nya, and went forward again. Now to the right, and now to the left, ran the narrow path that wound its way in the thickness of the mighty wall, which towered so high above them that they walked almost in darkness, and at each turn of it were recesses; and above these projecting stones, where archers could stand for its defence. At length this path ended in a _cul-de-sac_, for in front of them was nothing but blank masonry. Whilst Rachel and Noie stared at it wondering whither they should go now, a large stone in this wall turned, leaving a narrow doorway through which they passed, whereon it shut again behind them, though by what machinery they could not see. Thus they passed through the wall, emerging, however, at a different point in its circumference to that at which they had entered. In the centre of the enclosure rose the hill of earth that they had seen from without, which evidently was kept free from weeds and swept, and on its crest grew the huge cedar-like tree, the Tree of the Tribe. Between the base of this hill and the foot of the wall was a wide ring of level ground, also swept and weeded, and on this space, neatly arranged in lines, were hundreds of little hillocks that resembled ant-heaps. “The burying-place of the Ghost-priests, Lady,” said Nya, nodding at the hillocks. “Soon my bones will be added to them.”
