Reluctantly Serano affixed his signature.

"Thank you," said O'Connor, with mock respect, as he took the paper. "Now there is just one more little favor that I feel sure you will be pleased to grant me, and that is to step upstairs with my men and see how you like the room the American boys have just vacated. You will find it quite comfortable. Our accommodations are a little overtaxed just now. Don't forget to leave your key at the office when you go out, and don't blow out the gas. Now boys, show the new guest to his room."

O'Connor laughed until he was forced to hold his sides as his men, delighted with their task, roughly hustled the astonished and fuming officer along the corridor and up the steps. They heard an iron door slam and the men returned and saluted with grinning faces.

"Always find it a good thing to let your men have a little enjoyment mixed in with their work. Come on now, let's say good-bye to Monte and go. It only lacks an hour of midnight and when the watch changes it will not be long before our little game is discovered."

As he spoke, O'Connor walked to the door of the officer's room and looked in, followed by the boys.

"Good-bye, Mr. Interpreter," said Harry, "what are the quotations on glory to-night?"

Villamonte wagged the ends of his waxed mustache in an effort to speak. O'Connor laughed and turning to the door, unlocked it, and slipping back the bolts, gave a low whistle, like the one the boys had heard from their cell window. In a moment the answer came.

"Come on," said O'Connor, "the coast is clear."

They passed silently out into the night. The eight men joined their comrades and the next moment, one by one, they darted across the streak of moonlight and disappeared in the deep shadow of the building at the corner of the square. O'Connor stopped and looked around to see if they had been observed, but the streets were deserted.

"Aren't you afraid that General Serano will yell through the window and give an alarm?" asked Harry, looking up to the bars of the cell they had so recently occupied.
