"Let us make haste, Monseigneur," he cried; "the stone will not move. I managed to open the passage, but now I cannot close it."

In fact, the stone, from a long disuse, had stiffened, so to speak, in its groove, and it was impossible to start it again.

"Monseigneur," said Halmalo, "I hoped to close the passage, so that when the Blues came in and found no one here they would not know what to make of it, and might imagine that you had all vanished in smoke. But the stone is not to be moved, and the enemy will find the outlet and probably pursue us; so let us lose not a minute, but reach the staircase as quickly as we can."

The Imânus laid his hand on Halmalo's shoulder.

"Comrade," he said, "how long will it take to go through this passage and reach the woods in safety?"

"Are any of the men seriously wounded?" asked Halmalo.

"None," they answered.

"In that case, a quarter of an hour will be sufficient."

"So if the enemy does not get in here for a quarter of an hour—" rejoined the Imânus.

"He might pursue, but he could not overtake us."
