For a time, the two lads sat silent. John was the first to speak.

"I am thankful," he said, "that, owing to our being down the face of the rock, the sound is carried away above our heads, and we can hear but little of what is going on there. It seems a confusion of sounds, and comes to us rather as an echo from the hills, yonder, than directly from above."

Sometimes, indeed, thrilling screams and shouts were heard but, for the most part, the sounds were so blended together that they could not be distinguished one from another. As soon as the mist cleared off, the lads lay down, as far back from the ledge as they could get.

"We must not lift up a head, today," John said. "The guards below, and on the hills, will have their eyes fixed on the rock, on the lookout for fugitives and, until nighttime, we must not venture to sit up. Fortunately, that outer edge of the shelf is a good deal higher than it is, back here; and I don't think that even those on the mountain, opposite, could see us as we lie."

"I should think a good many may escape, like us," Jonas said, presently. "There are numbers of caverns and passages, from which they have dug the stone for the building of the houses. A lot of the people are sure to hide away, there."

"I daresay they will," John agreed; "but I fear the Romans will hunt them all out."

"How long do you think we shall have to stay here, John?"

"Till the Romans go, whether it is one week or two; but I do not think they will stay here many days. The town is so full of dead that, in this hot weather, it will be unbearable before long. At any rate, we shall be able to pass a good deal of time in sleep. We have not had much of it, lately. Till last night, I have not been in the house, at night, for over a fortnight. But I felt, last night, as if I must have a sleep, whatever came of it. I suppose the guards at the breach must have felt the same, or the Romans could never have got in without the alarm being given."

For a few minutes, John lay thinking of the terrible scenes that must be passing, on the rock above; then his drowsiness overcame him, and he was soon fast asleep.

It was dark when he woke. As he moved, Jonas spoke.
