We had nearly touched the landing, when we observed that a discussion was going on between Ala and Ingra, and it quickly became evident that we were the subject of it. Before we could exchange a word, they approached us, and Ingra, in a threatening manner, laid his hand on Edmund's shoulder. In a second Jack had his pistol covering Ingra. Edmund saw the motion, and struck Jack's arm aside, but the weapon exploded, and, clutching her breast, Ala fell at our feet! CHAPTER X IMPRISONMENT AND A WONDERFUL ESCAPE The shock of this terrible accident, the full import of which must have flashed simultaneously through the mind of every one of us, drove the blood from Edmund's face, while Jack staggered, uttering a pitiful moan, Henry collapsed, and I stood trembling in every limb. The report of the pistol produced upon the natives the effect that was to have been expected. Ingra sprang backward with a cry like that of a startled beast, and many upon the deck fell prostrate, either through terror or the effect of collision with one another in their wild flight. What occurred among the waiting crowd on the tower I do not precisely know, but a wind of fear seemed to pass through the air--a weird, heart-quaking _shadow of sound_. For a few moments, I believe, no one but ourselves understood what had happened to Ala. Ingra may have thought, if he thought at all in his terror and surprise, that she had fallen as the result of nervous shock. This moment of paralysis on the part of those whom we had now to regard as our enemies, whatever they may have been before, afforded the opportunity for escape--if there had been any way to escape. But we were completely trapped; there was no direction in which we could flee. Yet I doubt if the thought of flight occurred to any of us. Certainly it did not to Edmund, who was the first to recover his self-command. "_We have shot down our only friend!_" he said with terrible emphasis, and, as he spoke, he lifted Ala in his arms and laid her on a seat. Her breast was stained with blood. At the sight of this, a flash of comprehension passed over the features of Ingra; then, instantly, his face changed to a look of fury, and he sprang upon Edmund. With trembling hand, I tried to draw my pistol, but before I could get it from my pocket there was a rush, a hairy form darted past me, and Ingra lay sprawling on his back. Over him, with foot planted on his breast, stood the burly form of Juba, with his muscular arms uplifted, and his enormous eyes blazing fire!
