At this, it must be confessed, the young man's step lost its elasticity; his head sunk visibly, and the love just found was driven to divide its dominion with a well-grounded practical apprehension. Yet he walked on, out of the gate, and thence in the direction of the cistern.

Arrived there, he surveyed the wooden structure doubtfully. The door was open, and just inside of it the keeper sat stick in hand drumming upon the brick pavement, a man of medium height and rather pleasant demeanor.

"I am a stranger here," Sergius said to him. "The cistern is public, I believe; may I see it?"

"It is public, and you may look at it all you want. The door there at the end of the passage will let you into the court. If you have trouble in finding the stairway down, call me."

Sergius dropped some small coin into the keeper's hand.

The court was paved with yellow Roman brick, and moderately spacious. An oblong curbing in the centre without rails marked the place of descent to the water. Overhead there was nothing to interfere with the fall of light from the blue sky, except that in one corner a shed had been constructed barely sufficient to protect a sedan chair deposited there, its poles on end leant against the wall. Sergius noticed the chair and the poles, then looked down over the curbing into a doorway, and saw four stone steps leading to a platform three or four feet square. Observing a further descent, he went down to the landing, where he paused long enough to be satisfied that the whole stairway was built into the eastern wall of the cistern. The light was already dim. Proceeding carefully, for the stones were slippery, he counted fourteen steps to another landing, the width of the first but quite ten feet long, and slightly submerged with water. Here, as he could go no further, he stopped to look about him.

It is true there was not much to be seen, yet he was at once impressed with a sense of vastness and durability. A dark and waveless sheet lay stretched before him, merging speedily into general blackness. About four yards away and as many apart, two gigantic pillars arose out of the motionless flood stark and ghostly gray. Behind them, suggestive of rows with an aisle between, other pillars were seen, mere upright streaks of uncertain hue fainter growing in the shadowy perspective. Below there was nothing to arrest a glance. Raising his eyes to the roof above him, out of the semi-obscurity, he presently defined a brick vault springing boldly from the Corinthian capitals of the nearest pillars, and he knew straightway the roof was supported by a system of vaults susceptible of indefinite extension. But how was he, standing on a platform at the eastern edge of the reservoir, mighty in so many senses, to determine its shape, width, length? Stooping he looked down the vista straining his vision, but there was no opposite wall--only darkness and impenetrability. He filled his lungs trying the air, and it was damp but sweet. He stamped with force--there was a rumble in the vault overhead--that was all. He called: "Lael, Lael"--there was no answer, though he listened, his soul in his ears. Therewith he gave over trying to sound the great handmade cavern, and lingered awhile muttering:

"It is possible, it is possible! At the end of this row of pillars"--he made a last vain effort to discover the end--"there may be a house afloat, and she"--he clinched his hands, and shook with a return of murderous passion--"God help her! Nay, God help me! If she is here, as I believe, I will find her."

In the court he again noticed the sedan in the corner.

"I am obliged to you," he said to the keeper by the door. "How old is the cistern?"

"Constantine begun it, and Justinian finished it, they say."

"Is it in use now?"

"They let buckets down through traps in the roof."

"Do you know how large it is?" [Footnote: Yere Batan Serai, or the Underground Palace, the ancient Royal Cistern, or cistern of Constantine, is in rank, as well as in interest and beauty, the chief Byzantine cistern. It is on the right-hand side of the tramway street, west of St. Sophia. The entrance is in the yard of a large Ottoman house in last street on the right of tramway street before the tramway turns abruptly west (to right) after passing St. Sophia.

This cistern was built by Constantine the Great, and deepened and enlarged by Justinian the Great in 527, the first year of his reign. It has been in constant use ever since. The water is supplied from unknown and subterranean sources, sometimes rising nearly to the capitals of the columns. It is still in admirable preservation: all its columns are in position, and almost the entire roof is intact. The columns are arranged in twelve rows of twenty-eight, there being in all three hundred and thirty-six, which are twelve feet distant from each other or from the wall. Some of the capitals are Corinthian; others plain, hardly more than truncated pyramids. The roof consists of a succession of brick vaults.

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.

"BYZANTINES!

"Fathers and mothers of Byzantium!

"Lael, the daughter of Uel the merchant, has not been found. Wherefore I now offer 10,000 bezants in gold for her dead or alive, and 6,000 bezants in gold for evidence which will lead to the discovery and conviction of her abductors.

"The offers will conclude with to-day.

"PRINCE OF INDIA."

There was a sensation when the new placards had been generally read; yet the hunt of the day before was not resumed. It was considered exhausted. Men and women poured into the streets and talked and talked--about the Prince of India. By ten o'clock all known of him and a great deal more had gone through numberless discussions; and could he have heard the conclusions reached he had never smiled again. By a consensus singularly unanimous, he was an Indian, vastly rich, but not a Prince, and his interest in the stolen girl was owing to forbidden relations. This latter part of the judgment, by far the most cruel, might have been traced to Demedes.

In all the city there had not been a more tireless hunter than Demedes. He seemed everywhere present--on the ships, on the walls, in the gardens and churches--nay, it were easier telling where he had not been. And by whomsoever met, he was in good spirits, fertile in suggestions, and sure of success. He in fact distinguished himself in the search, and gave proof of a knowledge of the capital amazing to the oldest inhabitants. Of course his role was to waste the energy of the mass. In every pack of beagles it is said there is one particularly gifted in the discovery of false scents. Such was Demedes that first day, until about two o'clock. The results of the quest were then in, and of the theories to which he listened, nothing pleased him like the absence of a suggestion of the second sedan. There were witnesses to tell of the gorgeous chair, and its flitting here and yonder through the twilight; none saw the other. This seems to have sufficed him, and he suddenly gave up the chase; appearing in the garden of the Bucoleon, he declared the uselessness of further effort. The Jewess, he said, was not in Byzantium; she had been carried off by the Bulgarians, and was then on the road to some Turkish harem. From that moment the search began to fall off, and by evening it was entirely discontinued.

Upon appearance of the placards the second day, Demedes was again equal to the emergency. He collected his brethren in the Temple, organized them into parties, and sent them everywhere--to Galata, to the towns
