A Story of Constantinople and the Caucasus. The following story relates to that exceedingly interesting and romantic portion of the world bordering on the Black Sea, the Sea of Marmora, and the Bosphorus. The period of the story being quite modern, its scenes are a transcript of the present time in the city of the Sultan. The peculiarities of Turkish character are of the follower of Mahomet, as they appear to-day; and the incidents depicted are such as have precedents daily in the oriental capital. Leaving the tale to the kind consideration of the reader, the author would not fail to express his thanks for former indulgence and favor.
