"It is more than anxiety; it is pain," he answered. I supposed that he was thinking of Hermione, and was silent. Presently he proposed to go out. It was a fine day in February, though the snow was on the ground and filled the ruts in the pavement of the Grande Rue de Pera. Every one was wrapped in furs and every one wore overshoes, without which it is impossible to go out in winter in Constantinople. The streets were crowded with that strange multitude seen nowhere else in the world; the shops were full of people of all sorts, from the ladies of the embassies to the veiled Turkish ladies, who have small respect for the regulation forbidding them to buy in Frank establishments. At Galata Serai the huge Kurdish hamáls loitered in the sun, waiting for a job, their ropes and the heavy pillows on which they carry their burdens lying at their feet. The lean dogs sat up and glared hungrily at the huge joints of meat which the butchers' lads carried through the crowd, forcing their way past the delicate Western ladies, who drew back in horror at the sight of so much raw beef, and through knots of well-dressed men standing before the cafés in the narrow street. Numberless soldiers moved in the crowd, tall, fair Turks, with broad shoulders and blue eyes, in the shabby uniform of the foot-guards, but looking as though they could fight as well as any smart Prussian grenadier, as indeed they can when they get enough to eat. Now and then a closed sedan-chair moved rapidly along, borne by sturdy Kurds, and occasionally a considerable disturbance was caused by the appearance of a carriage. Paul and I strolled down the steep street, past Galata Tower and down into Galata itself.

"Shall we cross?" asked Paul, as we reached the bridge.

"Let us go up the Bosphorus," I said. "There will probably be a steamer before long."

He assented readily enough. It was about eleven o'clock in the morning,—five by the Turkish clocks,—and the day was magnificent. The sun was high, and illuminated everything in the bright, cold air, so that the domes and minarets of the city were white as snow, with bluish shadows, while the gilded crescents and spires glistened with unnatural brilliancy in the clear winter's daylight. It is hard to say whether Stamboul is more beautiful at any one season of the year than during the other three, for every season brings with it some especial loveliness, some new phase of color. You may reach Serai point on a winter's morning in a driving snow-storm, so that everything is hidden in the gray veil of the falling flakes; suddenly the clouds will part and the sunlight will fall full upon the city, so that it seems as if every mosque and spire were built of diamonds. Or you may cross to Scutari in the early dawn of a morning in June, when the sky is like a vast Eastern flower, dark blue in the midst overhead, the petals shaded with every tint to the faint purple on the horizon; and every hue in turn passes over the fantastic buildings, as the shadows gradually take color from the sky, and the soft velvety water laps up the light in broad pools and delicate streaks of tinted reflection. It is always beautiful, always new; but of all times, I think the hour when the high sun illuminates most distinctly everything on land and sea is the time when Stamboul is most splendid and queenly.

The great ferry-boat heaved and thumped the water, and swung slowly off the wooden pier, while we stood on the upper deck watching the scene before us. For two men as familiar with Constantinople in all its aspects as we were, it seemed almost ridiculous to go on board a steamer merely for the sake of being carried to the mouth of the Black Sea and back again. But I have always loved the Bosphorus, and I thought it would amuse Paul to pass the many landings, and to see the crowds of passengers, and to walk about the empty deck. He was tired with the journey and harassed in mind, and for those ills the open air is the best medicine.

He appeared to enjoy it, and asked me many questions about the palaces and villas on both shores, for I was better acquainted with the place than he. It seemed to interest him to know that such a villa belonged to such a Pasha, that such another was the property of an old princess of evil fame, while the third had seen strange doings in the days of Mehemet Ali, and was now deserted or inhabited only by ghosts of the past,—the resort of ghouls and jins from the neighboring grave-yards. As we lay a moment at the pier of Yeni Köj,—"New town" sounds less interesting,—we watched the stream of passengers, and I thought Paul started slightly as a tall, smooth-faced, and hideous negro suddenly turned and looked up to where we stood on the deck, as he left the steamer. I might have been mistaken, but it was the only approach to an incident of interest which occurred that day. We reached the upper part of the Bosphorus, and at Yeni Mahallè, within sight of the Black Sea, the ferry-boat described a wide circle and turned once more in the direction of Stamboul.

"I feel better," said Paul, as we reached Galata bridge and elbowed our way ashore through the crowd. "We will go again."

"By all means," I answered.

From that time during several weeks we frequently made excursions into Stamboul and up the Bosphorus, and the constant enjoyment of the open air did Paul good. But I could see that wherever we went he watched the people with intense interest; following some individual with his eyes in silence, or trying to see into dark archways and through latticed windows, staring at the files of passengers who came on board the boats or went ashore at the different landings, and apparently never relaxing his attention. The people grew familiar to me, too, and gradually it appeared that Paul was constructing a method for our peregrinations. It was he, and not I, who suggested the direction of our expeditions, and I noticed that he chose certain places on certain days. On Monday, for instance, he never failed to propose a visit to the bazaars, on Tuesday we generally went up the Bosphorus, on Wednesday into Stamboul. On Friday afternoons, when the weather was fine, we used to ride out to the Sweet Waters of Europe; for Friday is the Mussulman's day of rest, and on that day all who are able love to go out to the Kiat-hané—the "paper-mill,"—where they pass the afternoon in driving and walking, eating sweetmeats, smoking, drinking coffee, watching gypsy girls dance, or listening to the long-winded tales of professional story-tellers. Almost every day had its regular excursion, and it was clear to me that he always chose the place where on that day of the week there was likely to be the greatest crowd.

Meanwhile Balsamides, in whose house I continued to live, alternately laughed at me for believing Paul's story, and expressed in the next breath a hope that Alexander might yet be found. He had been to Santa Sophia, and had ascertained that the other staircase was usually opened on the nights when the mosque was illuminated, for the convenience of the men employed in lighting the lamps, and this confirmed his theory about the direction taken by Alexander when he left the gallery. But here all trace ceased again, and Balsamides was almost ready to give up the search, when an incident occurred which renewed our energy and hope, and which had the effect of rousing Paul to the greatest excitement.
