Soon the crevice was clear, and from where I stood I commanded a view of something like three-quarters of the ledge. It was one mass of black forms, packed tightly together, gazing at our retreat.
They looked particularly silly and helpless to me then, rendered powerless as they were by a little bit of rock. Brute force was all they had; and nature, being the biggest brute of all, laughed at them.
But I soon found that they were not devoid of resource. For perhaps fifteen minutes the scene remained unchanged; not one ventured to approach the crevice. Then there was a sudden movement and shifting in the mass; it split suddenly in the middle; they pressed off to either side, leaving an open lane between them leading directly toward me.
Down this lane suddenly dashed a dozen or more of the savages, with spears aloft in their brawny arms. I was taken by surprise and barely had time to cut and run for the ledge within.
As it was I did not entirely escape; the spears came whistling through the crevice, and one of them lodged in my leg just below the thigh.
I jerked it out with an oath and turned to meet the attack. I was now clear of the crevice, standing on the ledge inside, near Harry and Desiree. I called to them to go to one side, out of the range of the spears that might come through. Harry took Desiree in his arms and carried her to safety.
As I expected, the Incas came rushing through the crevice—that narrow lane where a man could barely push through without squeezing. The first got my spear full in the face—a blow rather than a thrust, for I had once or twice had difficulty in retrieving it when I had buried it deep.
As he fell I struck at the one behind. He grasped the spear with his hand, but I jerked it free and brought it down on his head, crushing him to the ground. It was mere butchery; they hadn't a chance in the world to get at me. Another fell, and the rest retreated. The crevice was again clear, save for the bodies of the three who had fallen.
I turned to where Harry and Desiree were seated on the further edge of the ledge. Her body rested against his; her head lay on his shoulder.
As I looked at them, smiling, her eyes suddenly opened wide and she sprang to her feet and started toward me.
