On nearly every tablet he saw the same sweet and gentle word. "PEACE," thought Marcellus; "what wonderful people are these Christians, who even amid such scenes as these can cherish their lofty contempt of death!"

      His eyes grew more and more accustomed to the gloom as he walked along. Now the passage way grew narrower; the roof drooped, the sides approached; they had to stoop and go along more slowly. The walls were rough and rudely cut as the workmen left them when they drew along here their last load of sand for the edifices above. Subterranean damps and fungous growths overspread them in places, deepening their somber color and filling the air with thick moisture, while the smoke of the torches made the atmosphere still more oppressive.

      They passed hundreds of side passages and scores of places where many paths met, all branching off in different directions. These innumerable paths showed Marcellus how hopelessly he was now cut off from the world above. This boy held his life in his hands.

      "Do any ever lose their way?"

      "Often."

      "What becomes of them?"

      "Sometimes they wander till they meet some friends, sometimes they are never heard of again. But at present, most of us know the place so well that if we lose our way we soon wander into familiar paths again."

      One thing particularly struck the young soldier, and that was the immense preponderance of small tombs. Pollio told him that they were the graves of children, and thus opened to him thoughts and emotions unfelt before.

      "Children!" thought he, "what do they here, the young, the pure, the innocent? Why were they not buried above, where the sun might shine kindly and the flowers bloom sweetly over their graves? Did they tread such dark paths as these on their way through life? Did they bear their part in the sufferings of those that lingered here flying from persecution? Did the noxious air and the never-ending gloom of these drear abodes shorten their fair young lives, and send their stainless spirits out of life before their time?"

      "We have been a long time on the way," said Marcellus, "will we soon be there?"

      "Very soon," said the boy. Whatever ideas Marcellus might have had about hunting out these fugitives before he entered here, he now saw that all attempts to do so must be in vain. An army of men might enter here and never come in sight of the Christians. The further they went, the more hopeless would be their journey. They could be scattered through the innumerable passages and wander about till they died.
