It is to be remembered now, as very material to our story, that the day the Prince of India resolved on the excursion up the Bosphorus with Lael the exquisite stretch of water separated the territorial possessions of the Greek Emperor and the Sultan of the Turks.

In 1355 the utmost of the once vast Roman dominions was "a corner of Thrace between the Propontis (Marmora) and the Black Sea, about fifty miles in length and thirty in breadth." [Footnote: Gibbon.]

When Constantine Dragases--he of whom we are writing--ascended the throne, the realm was even more diminished.

Galata, just across the Golden Horn, had become a Genoese stronghold.

Scutari, on the Asiatic shore almost vis-a-vis with Constantinople, was held by a Turkish garrison.

With small trouble the Sultan could have converted the pitiful margin between Galata and the Cyanean rocks on the Black Sea.

Once indeed he set siege to Constantinople, but was beaten off, it was said, by the Mother of God, who appeared upon the walls of the city, and in person took part in the combat. Thereafter he contented himself with a tribute from the Emperors Manuel and John Palaeologus.

The relations of the Christian and Moslem potentates being thus friendly, it can be seen how the Princess Irene could keep to her palace by Therapia and the Prince of India plan jaunts along the Bosphorus.

Still there is a point to be borne in mind. Ships under Christian flags seldom touched at a landing upon the Asiatic shore. Their captains preferred anchoring in the bays and close under the ivy-covered heights of Europe. This was not from detestation or religious intolerance; at bottom there was a doubt of the common honesty of the strong-handed Turk amounting to fear. The air was rife with stories of his treachery. The fishermen in the markets harrowed the feelings of their timid customers with tales of surprises, captures, and abductions. Occasionally couriers rushed through the gates of Constantinople to report red banners in motion, and the sound of clarions and drums, signifying armies of Moslems gathering for mysterious purposes.

The Moslems, on their part, it is but fair to say, were possessed of the same doubts of the Christians, and had answers to accusations always ready. The surprises, captures, and abductions were the unlicensed savageries of brigands, of whom they never knew one not a Greek; while the music and flags belonged to the militia.

Six or seven miles above Scutari a small river, born in the adjacent highlands, runs merrily down to meet and mingle with the tideless Bosphorus. The water it yields is clear and fresh; whence the name of the stream, The Sweet Waters of Asia. On its south side there is a prairie-like stretch, narrow, but green and besprent with an orchard of sycamores old and gnarled, and now much frequented on Mohammedan Sundays by ladies of the harems, who contrive to make it very gay. No doubt the modest river, and the grass and great trees were just as attractive ages before the first Amurath, with an army at his heels, halted there for a night. From that time, however, it was banned by the Greeks; and for a reason.

On the north bank of the little river there was a fortress known as the White Castle. An irregular, many-angled pile of undressed stone heavily merloned on top, its remarkable feature was a tall donjon which a dingy white complexion made visible a great distance, despite its freckling of loopholes and apertures for machine artillery. Seeing its military importance, the Sultan left a garrison to hold it. He was also pleased to change its name to Acce-Chisar.

The blood-red flag on this donjon was, at the era engaging us, the disenchanter of the Greeks; insomuch that in passing the Sweet Waters of Asia they hugged the opposite shore of the Bosphorus, crossing themselves and muttering prayers often of irreligious compound. A stork has a nest on the donjon now. As an apparition it is not nearly so suggestive as the turbaned sentinel who used to occupy its outlook.

The popular imagination located dungeons under the grim old Castle, whence, of the many Christian men and women immured there, it was said none ever came forth alive.

But for these things, whether true or false, the Prince of India cared little. He was not afraid of the Turks. If the Asiatic shore had been festooned with red flags from the City of the Blind down by the Isles of the Princes to the last of the gray fortresses overlooking the Symplegades, it would not have altered a plan of his jot or tittle. Enough that Lael wanted and needed an outing on the glorious Bosphorus.

Accordingly, shortly after noon two chairs were brought and set down in his house. That is to say, two upright boxes fixed centrally on poles, and differing in nowise from the sedans still the mode of carriage affected by ladies of Constantinople unless it might be in their richer appointments. Inside, all was silk, lace and cushions; outside, the inlaying of mother of pearl and vari-colored woods was suggestive of modern papier-mache. The entrance was by a door in the front. A window in the door, and lesser ones on the sides, afforded the inmate air and opportunity for speech. Not wanting to be seen, she had only to draw the curtains together. In this instance it must be said the decoration of the carriages had been carried to an extreme.

Soon as the chairs were set down in the house, the Prince and Lael descended the stairs. The latter was attired in a semi-Greek costume, very rich and becoming; to embroidery of gold, she added bracelets, and a necklace of large pearls strung between spheres of gold equally large. A coronet graced her head, and it was so bejewelled that in bright light it seemed some one was sprinkling her with an incessant shower of sparkles.

The two took their seats. The carriers, two to each litter, stalwart men, uniformly clad in loose white garments, raised the poles on their shoulders. Syama threw the door of the house open, and at a signal from the Prince the procession sallied into the street. The crowd, in expectant waiting there, received it in silent wonder.

It is due the truth to say now that the common eye was attracted by the appearance of Nilo as much as by the rarities wrought in the panelling of the carriages. He strode ten or twelve feet in advance of Lael who, in the place of honor, was completely under the Prince's observation. The negro's costume was of a King of Kash-Cush. The hair stood on end in stiff cues, sharply pointed, and held by a chain of silver medals; an immense ring of silver hung from the cartilage of his nose. The neck was defended by a gorget of leather bristling with the fangs and claws of tigers in alternating rows. A robe of scarlet cloth large enough to envelop the man was thrown behind the massive shoulders. The body, black as polished ebony, was naked to the waist, whence a white skirt fell to the knees. The arms and legs were adorned with bracelets and anklets of ivory, while the straps of the heavy sandals were bordered with snail-shells. On the left arm he bore a round shield of rhinoceros hide embossed in brass; in the right hand, a pointless lance. Towering high above the heads of the crowd which opened before him with alacrity, the admiration received by the Prince's ally and friend was but a well-deserved tribute.

"A tiger-hunter!" said one, to a friend at his elbow.

"I should call him king of the tiger-hunters," the friend replied.

"Only a Prince of India would carry such a pensioner with him," another remarked.

"What a man!" said a woman, half afraid.

"An infidel, no doubt," was the answer.

"It is not a Christian wish, I know," the first added; "still I should like to see him face a lion in the Cynegion."

"Ay, him they call Tamerlane, because he is shorn of two toes."

The Prince, casting a glance of scarce concealed contempt over the throng, sighed, as he muttered, "If now I could meet the Emperor!"

The exclamation was from his heart.

We have seen the idea which lured him to Mecca, and brought him to Constantinople. In the years since flown, it was held subordinate to his love of Lael--subordinate merely. Latterly it had revived with much of its original force, and he was now for the first time seriously scheming for an interview with the Emperor. No doubt a formal request would have secured the honor; but it was in his view better policy to be sought than seek, and with all his wealth, there was nothing he could so well afford to pay for success as time. In his study, he was continually saying to himself:

"It cannot be that the extravagances to which I am going will fail. He will hear of me, or we may meet--then the invitation!--And then I will propose the Brotherhood--God help me! But it is for him to invite me. Patience, O my soul!"

Extravagances!

The exclamation helps us to an understanding of the style he was carrying before the public--the silvering on his own black velvet robe, the jewels in Lael's coronet bursting with light, the gorgeous finish of the sedans, the barbaric costuming of Nilo. They were not significant of his taste. Except for what they might bring him, he did not care for jewels. And as for Lael, he would have loved her for her name's sake, and her honest, untarnished Jewish blood. Let us believe so at least until we find otherwise.

Nilo, by this time familiar with every quarter of the city, was told the boat was in readiness for the party at a landing near the Grand Gate of Blacherne; to make which, it being on the Golden Horn well up in the northwes............
