"What! Are you going away?"
"Yes; I shall leave you for an hour or two. Keep a good watch. If you notice anything new you will imitate the cry of the waterhen twice: you understand?"
"Perfectly; but if a serious danger threatened us what ought I to do?"
The Tigrero reflected for an instant.
"What danger can threaten you here?" he said.
"I do not know; but the Indians are fiends incarnate: with them you must be prepared for anything."
"You are right. Well, in case of any serious danger threatening us—but only in that case, you understand—after giving your signal, you will put across to that point. Mangroves grow there, under the shelter of which you will be perfectly safe, and I will join you immediately."
"Very good: but how shall I know where to find you?"
"I will imitate twice the bark of the prairie dog. Now, be prudent."
"You may be sure of that."
