A long and weary march it was; and all were glad when the guide stopped before what seemed a mere mass of vines and bushes, at the foot of a rock. These he drew aside with a careful hand, and disclosed a low door, through which they passed; the younger lad closed it softly again, and they advanced as before. But it was now a very different way. The fresh, pure, evening air had been exchanged for the damp, musty smell of this underground passage. The sides were so close together that two persons could hardly have passed each other; the stranger had to stoop his head many a time to escape a blow from the jutting points of the roof; while the masses of rock which had fallen so encumbered the way that it required, at times, no small skill in climbing, to pass at all. Descending some flights of rough steps, and passing through another door, they found themselves in a much wider space, though it was still all dark and stony, but the roof was higher and the floor was smooth. A low hum of distant voices was now heard, which grew louder as they turned a corner and stopped before a door. A light tap was answered by one from within, and, as the door opened, such a flood of light poured upon them, that they shrunk back, with pained eyes, from the glare. The light of many torches revealed a low, broad, windowless room, with a raised platform, and rude reading-desk at one end, and between thirty and forty persons--men, women and children. Some were engaged in earnest conversation, some sat in silent thought, while others were attending to the children. At the entrance of the new comer, all arose and stood respectfully, while he threw aside his long cloak and cap, and stepped up to the platform. The two boys stood at his side, and all turned to him with expectant looks.
