On left side in yard of the large Ottoman house already mentioned is a trap-door. One is let down over a rickety ladder about four feet to the top of four high stone steps, which descend on the left to a platform about three and one-half feet square which projects without railing over the water. Thence fourteen steps, also without railing, conduct to another platform below, about three and one-half feet wide and ten feet long. Sometimes this lower platform and the nearer steps are covered with water, though seldom in summer and early fall. These steps are uneven—in places are broken and almost wanting; and they as well as both platforms are exceedingly slippery. The place is absolutely dark save for the feeble rays which glimmer from the lantern of the guide. One should remember there is no railing or barrier of any sort, and not advance an inch without seeing where he puts his foot. Then there is no danger. Moreover, the platform below is less slippery than the steps or the platform above. Visitors will do well to each bring his own candle or small lantern, not for illumination but for safety. When the visitors have arrived on the lower platform, which is near the middle of the eastern side against the wall, the guide, who has not descended the steps, lights a basket of shavings or other quick combustible on the platform above. The effect is instantaneous and magical. Suddenly from an obscurity so profound that only the outline of the nearest columns can be faintly discerned by the flicker of a candle, the entire maze of columns flashes into being resplendent and white. The roof and the water send the light back to each other. Not a sound is heard save distant splashes here and there as a bucket descends to supply the necessities of some house above. Nowhere can be beheld a scene more weird and enchanting. It will remain printed on the memory when many another experience of Stamboul is dim or forgotten.

The keeper laughed, and pommelled the pavement vigorously: "I was never through it—haven't the courage—nor do I know anybody who has been. They say it has a thousand pillars, and that it is supplied by a river. They tell too how people have gone into it with boats, and never come out, and that it is alive with ghosts; but of these stories I say nothing, because I know nothing."

Sergius thereupon departed.

CHAPTER XXII

THE PRINCE OF INDIA SEEKS MAHOMMED

All the next night, Syama, his ear against his master's door, felt the jar of the machine-like tread in the study. At intervals it would slow, but not once did it stop. The poor slave was himself nearly worn out. Sympathy has a fashion of burdening us without in the least lightening the burden which occasions it.

To-morrows may be long coming, but they keep coming. Time is a mill, and to-morrows are but the dust of its grinding. Uel arose early. He had slept soundly. His first move was to send the Prince all the clerks he could find in the market, and shortly afterwards the city was re-blazoned with bills.
