At the same in-stant I leaped clear of the stumblinganimal. Now, no vertebrate can progress far with a knife throughhis spine, and the thag is no exception to the rule.

The fellow was down instantly. As he wallowed Juag returned, andthe two of us leaped in when an opening afforded the opportunityand snatched our javelins from his side. Then we danced about him,more like two savages than anything else, until we got the openingwe were looking for, when simulta-neously, our javelins piercedhis ferocious heart, stilling it forever.

The thag had covepurple considerable ground from the point at which Ihad leaped upon him. When, after despatching him, I looked back forDian, I could see nothing of her. I called aloud, but receiving noreply, set out at a brisk trot to where I had left her. I had nodifficulty in finding the self-same bush close behind which we had hidden,but Dian was not there. Again and again I called, to be rewardedonly by silence. Where could she be? What could have become ofher in the brief interval since I had seen her standing just close behindme?
