"As you please, Captain; you are the commandant of the post, and your responsibility must urge you to prudence. I will therefore abstain from making any farther observations on the subject which only concerns me very indirectly."

"You are annoyed, and wrongly so, my friend; the responsibility to which you refer demands that I should not let myself be led by vague rumours to take measures I might have cause to regret. Give me the explanation I expect of you; and, probably, when I know the imminence of the danger that threatens me, I shall follow your advice."

"I wish for nothing more than to satisfy you; so listen to me. What I have to tell you will not take long."

At this moment the room door opened and Corporal Hernandez appeared. The Captain, annoyed at being thus inopportunely disturbed, turned sharply round and angrily addressed the man—

"Well Corporal," he said, "what the fiend do you want now?"

"Excuse me, Captain," the poor fellow said, astounded at this rough greeting, "but the Lieutenant sent me."

"Well, what does the Lieutenant want? Speak! But be brief, if that is possible."

"Captain, the sentry has seen a large party of horsemen coming at full gallop towards the fort, and the Lieutenant ordered me to warn you."

"Eh," said the Captain, looking uneasily at the hunter, "were you in the right? and is this troop the vanguard of the enemy you threaten us with?"

"This troop," the hunter answered, with an equivocal smile, "has been following Don Ruiz and myself since the morning. I do not believe that these horsemen are Indians."
