[Footnote 1: If any reader doubts the existence of El Barr, as a city of gold carved from a single block, on the ground that such a work would be impossible, I refer him to an account of Petra, in the National Geographic Magazine for May, 1907. Petra, in all details, was carved from granite—a monolithic city.]

Blasé as the Legionaries were and hardened to wonders, the sight of this corridor and of the vast banquet-hall opening out of it, at the far end, came near upsetting their aplomb. The major even muttered an oath or two, under his breath, till Leclair nudged him with a forceful elbow.

Not thus must Franks, from Feringistan, show astonishment or admiration.

"May the peace be upon thee," all at once exclaimed Bara Miyan, gesturing for the Master to enter the vast hall. "Peace, until the rising of the day!"

"And upon thee, the peace!" the Master answered, with the correct Arabic formula. They entered, and after them the other Legionaries and the sub-chiefs of Jannati Shahr.

The banquet-hall was enormous. The Master's glance estimated it as about two hundred and fifty feet long by one hundred and seventy-five wide, with a height from golden floor to flat-arched roof of some one hundred and twenty-five. Embroidered cloths of camel's-hair and silk covered the walls. Copper braziers, suspended from the pillars, sent dim spirals of perfumed smoke aloft into the blue air.

About sixty feet from the floor, a row of clerestory windows, unglazed, admitted arrows of sunlight through a golden fretwork; and these arrows, piercing the incense vapor, checkered intricate patterns on the enormous, deep-piled Persian rugs of rose, lilac, and misty blue.

Tables and chairs, of course, there were none. A dakkah, or platform, in horseshoe shape, at the far end, covered with rugs and cushions, and with water-jars, large copper fire-pans, coffee-pots of silver, and shishahs (water-pipes) told where the feast was to be offered.

From a side door, as a silken curtain was drawn back, some fifteen slave-girls entered—whiter than their masters and in tight jackets and loose, silk trousers. These girls brought copper basins of rose-water for the Arabs' "lesser ablution" before a meal. Bara Miyan smiled slightly as he gestured the Legionaries also to wash hands and faces; but the Master, little relishing the idea of using this same water after the Arabs, shook his head.

Not thus slyly could the Olema inflict humiliation on unbelievers. A hard look crept into the Master's eyes. This covert insult, after the exchange of salt, boded very ill.
