its cryptic inscription.

Long Sin watched his master in silent admiration as, at last, he
drew forth the mystic ring for which they had dared all.

Without a word, Wu dropped it in the slot. It tinkled down the
runway, a protuberance hit a trigger and pushed it a hair's
breadth.

A noise behind them caused the two to turn startled. Even Wu had
not expected it.

On the other side of the chamber, a great rock in the ground
slowly turned, as though on a pivot. They watched, fascinated.
Even then Wu did not forget the precious ring, but as the rock
turned, reached down quickly and recovered it from the cup at the
floor.

Inch by inch the pivoted rock moved on its axis. They flashed
their lanterns full on it and, as it moved, they could see
disclosed huge piles of gold and silver in coins and bars and
ornaments, a chest literally filled with brilliants, set and
unset, rubies, emeralds, precious stones of every conceivable
variety, a cave that would have staggered even Aladdin--the rich
reward of the countless marauding operations of Bennett's other
personality.

For a moment they could merely stand in avaricious exultation.
