I had noticed that whenever I built a fire, Ajor outlined in the air before her with a forefinger an isosceles triangle, and that she did the same in the morning when she first viewed the sun. At first I had not connected her act with anything in particular, but after we learned to converse and she had explained a little of her religious superstitions, I realized that she was making the sign of the triangle as a Roman Catholic makes the sign of the cross. Always the short side of the triangle was uppermost. As she explained all this to me, she pointed to the decorations on her golden armlets, upon the knob of her dagger-hilt and upon the band which encircled her right leg above the knee--always was the design partly made up of isosceles triangles, and when she explained the significance of this particular geometric figure, I at once grasped its appropriateness. We were now in the country of the Band-lu, the spearmen of Caspak. Bowen had remarked in his narrative that these people were analogous to the so-called Cro-Magnon race of the Upper Paleolithic, and I was therefore very anxious to see them. Nor was I to be disappointed; I saw them, all right! We had left the Sto-lu country and literally fought our way through cordons of wild beasts for two days when we decided to make camp a little earlier than usual, owing to the fact that we had reached a line of cliffs running east and west in which were numerous likely cave-lodgings. We were both very tired, and the sight of these caverns, several of which could be easily barricaded, decided us to halt until the following morning. It took but a few minutes' exploration to discover one particular cavern high up the face of the cliff which seemed ideal for our purpose. It opened upon a narrow ledge where we could build our cook-fire; the opening was so small that we had to lie flat and wriggle through it to gain ingress, while the interior was high-ceiled and spacious. I lighted a faggot and looked about; but as far as I could see, the chamber ran back into the cliff. Laying aside my rifle, pistol and heavy ammunition-belt, I left Ajor in the cave while I went down to gather firewood. We already had meat and fruits which we had gathered just before reaching the cliffs, and my canteen was filled with fresh water. Therefore, all we required was fuel, and as I always saved Ajor's strength when I could, I would not permit her to accompany me. The poor girl was very tired; but she would have gone with me until she dropped, I know, so loyal was she. She was the best comrade in the world, and sometimes I regretted and sometimes I was glad that she was not of my own caste, for had she been, I should unquestionably have fallen in love with her. As it was, we traveled together like two boys, with huge respect for each other but no softer sentiment.
