On four different occasions, both in summer and in winter, I have sailed along the southern shore of the Black Sea almost from one extremity to the other; yet I do not remember having seen the sky free from heavy clouds during two consecutive days. As the ship speeds eastwards along the mountains of Bithynia, a thin veil of haze will blend the land outlines together; while, as the range grows in height with every mile of progress, the vapour will collect about its upper slopes in long, horizontal, black banks. Even when the sun of this southern climate has swept the sky of every lingering film, when the zenith and the water recall the hues of the Mediterranean--the whole scale of brilliant blues--somewhere upon the wide circle of the horizon will be lurking the scattered forces of the mist. But the stronghold of the cloud is in the mountains of Akhaltsykh, at the foot of Caucasus, in the extreme eastern angle of the sea. Can there exist a more gloomy coast? There the sky is always lowering above the inky water, and the forests of fir which clothe the range from foot to summit wave darkly, like feathers over a pall. Such, I think, are the impressions which the mind most closely associates with the aspect of this sea and shore. What a contrast to the smiling landscape of the Bosphorus, the strait through which we enter this sad sea or leave it on our return home! The cold draught follows the home-coming ship up the narrow channel between the wooded cliffs, and frets the running tide into crisp little waves which sparkle in the brilliant light. The dolphins leap from the blue water and dart shining through the air. To the traveller who is returning from a long journey in Asia and a tedious tossing on this grey sea, the Bosphorus, always bright and gay and beautiful, may appear as the promised gate of paradise beyond the world of shades.
