This began to peal like some exotic Tibetan gong as rocks struck it. For the rockers, standing off at a distance, had begun to zero in on his position. Jay used the dhal in his left hand to protect his bloody head. At the top of the oxygen tank was a round valve wheel—the main shutoff. Angling off to one side of that was a regulator with two dials. Sprouting from the low-pressure side of the regulator, then, was a Rube Goldbergian tangle of tees and wyes that had been kludged onto it so that it would feed something like a dozen separate oxygen tubes.
