"Then did you see?" asked Harry, excitedly.
Bert nodded quickly in the affirmative.
As the moon flashed out they had both seen a man dart closer into the protection of the deep shadow of the wall.
"There's another," whispered Bert, pointing out through the bars in his eagerness, to a point about ten feet beyond where the first man had appeared. "What if the guard should see them too?"
"The sentinels are on the same level and cannot see as well as we can up here. I wonder who they are. See, there is another."
"Who can they be?"
"I'll bet you a dinner when we get home that Captain Dynamite is in town."
"O, Hal, do you think we will ever get home?"
"I'm beginning to feel very sure of it. See, there are other men in the distance and all are coming toward the jail."
The prison stood in a narrow plaza or square facing the main street. Toward the dark shadow of a building that formed a corner of the square the indistinct forms of the men seemed to be making their way. The boys counted nearly a dozen, closely hugging the walls of the low houses, slip one by one into the wider shadow of the corner building. Still the regular steps of the guard below told that the mysterious gathering had not been discovered.
