gotten through. When I got my circle cut and the cut-out piece dropped inside, my rig was about at its last gasp. So was Sykes. For the last two hours he'd been hoppin' up an' down with impatience. "Thirty years' work," he kept saying. "I've waited for this for thirty years and I won't be stopped now. Hurry up! Hurry up!" And when we had to wait for the opening to cool I thought he'd go wild. I guess that's what built him up to his big breakdown. He sure was keyed up. Well, at last we crawled into the place.

Like short screams, one after the other, fast. He laughs and laughs. I carry him out. I put him down outside and go back in for my gear. I can hear him laughing out there and that busted-up voice of his echoing in the gulch. I get everything onto the back pack and go to put out the pressure
