"There is our scout," said he; and he answered the signal.

The gaucho appeared to have been running rapidly; his chest heaved, his face was covered with perspiration.

"Let us go, let us go!" said he, in a sad voice; "If, we do not want to be smoked out like wolves. In less than half an hour they will be here."

"The devil!" cried the Montonero; "That is bad news, companion."

"It is certain."

"What direction must we take?"

"That of the mountains."
