"Kosko gry! Romany gry!
Muk man kistur tuté knaw!"
"Clever little imp!" he thought. "He didn't give me away to his companions there, and now he's trying to smother the sound of my footsteps."
He turned the corner and waited. The sentry was still approaching with measured tread, and when he arrived beneath the grating he cried angrily:
"Tais-toi, maraud! Il faut te taire, ou je vais te brûler la cervelle."
The singing ceased, and the sentry with a grunt resumed his march.
"He's going to make the round of the building," thought Jack. "So will I; but I hope to goodness no one will be passing on the other side."
He tiptoed along and turned the other corner. Not a soul was to be seen. He waited. On this face of the building was the door, over which a feeble light flickered, and Jack wondered whether it was open, and if he would be seen from within. But there was no time for hesitation. The tramping sentry was coming behind him. Taking his courage in both hands, Jack slipped along, passed the door safely, turned the farther corner, and in another half-minute was back under the grating, breathless with excitement.
For a moment he stood listening. The sentry had halted in front of the building.
"Hist! Are you there?" he whispered towards the grating.
"Sí, Señor," said the man.
