Having wandered about through this melancholy relic of the past with old Surley at our heels, who in no way seemed to enter into our enthusiasm, we turned to retrace our steps to where we had left our horses.  We had observed some figures at a distance among the ruins, but they seemed to take no notice of us.  Suddenly they disappeared.  We found our guide standing by our horses where we had left him.  He seemed rather agitated, but we could not make out what had happened, as we did not understand a word of his language.  When we mounted, he inquired of us by signs whether we had got pistols.  We showed him that we had not, or arms of any sort.  He did not treat us as we afterwards thought he might have done had he not been an honest man, and say, "Oh, if that is the case, I will rob you myself."  He shook his head and showed us his own long knife, and signified that very likely we should have to use it for our defence.  Such was the interpretation, at all events, that we put on his various signs.  Silva, who had been a little behind, now came up.
