The black led us rapidly through the inner chambers of the temple, until we stood within the central court--a great circular space paved with a transparent marble of exquisite whiteness. Before us rose a golden temple wrought in the most wondrous and fanciful designs, inlaid with diamond, ruby, sapphire, turquoise, emerald, and the thousand nameless gems of Mars, which far transcend in loveliness and purity of ray the most priceless stones of Earth.

"This way," cried Xodar, leading us toward the entrance to a tunnel which opened in the courtyard beside the temple.

Just as we were on the point of descending we heard a deep-toned roar burst from the Temple of Issus, which we had but just quitted, and then a red man, Djor Kantos, padwar of the fifth utan, broke from a nearby gate, crying to us to return.

"The blacks have fired the temple," he cried. "In a thousand places it is burning now. Haste to the outer gardens, or you are lost."

As he spoke we saw smoke pouring from a dozen windows looking out upon the courtyard of the Temple of the Sun, and far above the highest minaret of Issus hung an ever-growing pall of smoke.

"Go back! Go back!" I cried to those who had accompanied me.
