"That stuff wouldn't pierce my two coats, to say nothing of the linked steel shirt," I sneered. "I will show them what fools they are!" and I walked boldly out to the brink and faced them. They let fly a quick volley with a concerted shout. As I saw the arrows start, I turned my back and bent down my head quickly. Perhaps a dozen of the slim reeds pelted me, and then I stooped over and gathered up as many as I could find, and broke them all in my hands before their eyes. This sent a hum of excited jabbering through their ranks, and they fired no more. I stood watching them, and presently I grasped my two hands together and shook hands with myself, to try to convey to them the idea that we were friendly; but it must have carried no meaning to them. By this time the slingers had come up, and I retired behind my shield to await their action. The archers seemed very glad of their arrival, and yielded the foremost place to them. I noted their operations carefully, and saw them place something, which did not look like a round stone, in the pocket of their slings, and then they whirled it long and cautiously. Suddenly they discharged it with a swift movement of their bodies backward, which landed them on one knee. "Wide of the mark!" I cried, as the missiles sailed off far to the right of us. But just before landing they bent a sharp, surprising curve, and lacked but little of hitting us behind the shields! The things they had thrown were the thin, concave shells of a large nut, and the trick of discharging them gave them their peculiar flight. "I don't like this throwing around the corner!" exclaimed the doctor. "With a little truer aim they will be able to hit us behind anything." "Hurry, bring your shield over behind mine, and face it the other way," said I; "then we will crouch between the two in safety." He did this just in time, for some of the next volley actually curved around and hit his shield, but none struck mine in front. However, the shells which fell near us were of light weight, and would not have bruised us much with heavy clothing on. Presently their pelting ceased, and we concluded that they were planning something new. We decided to let them know that we were not hurt, so we emerged; and I tried throwing the shells back with my hand, but I could not control their erratic course. When they saw this they jeered at me, and I itched to treat them to just one pistol shot, only to show them what child's play their fighting was! Presently we saw what they were waiting for. Far down the road the two great birds were returning harnessed together, and dragging behind them an enormous catapult. Tied across their backs were two stout darts, seemingly twelve feet long and three inches square. Each of them had a wicked-looking barbed tip.
