Mr. Sladen found that Cairo included a glorious mediaeval city of the Arabian Nights, with innumerable monuments of medieval Arab architecture and unspoiled native life. To this he strives to call attention in a book that he hopes to make "chatty and interesting." And he unquestionably succeeds. Mr. Sladen at his best is easily capable of writing. By reading the book the toursit will learn "How to Shop in Cairo," as well as how to enjoy the "Humors of the Esbekiya" and countless other entertaining features of this variegated modern capital. He will even know the "Artist's Bits in Cairo," and will receive explicit directions how to find them. In other words, he need no longer be a "tame tourist" in the hands of a masterful dragoman.
