In a sumptuous through train we now pass rapidly over nearly one thousand miles of a country which is intensely interesting, historically and ethnologically, and finally arrive in the famous city of Agra, which stands supreme among Indian cities as a centre of architectural beauty. We have here come into a distinctively Mohammedan region; and the edifices which crown the city with glory are not only connected with the Mohammedan faith, they are also the masterpieces of the greatest minds of the Mogul Empire, and culminate in the Taj Mahal, which is the most valued gem of Mohammedan architecture, and, perhaps, the most beautiful edifice in the world. We first turn our face toward the Fort, which is one of the magnificent fortresses of India. Two and a half centuries ago, Shah Jehan was the ruling Mogul. He was not only one of the greatest rulers of the dynasty; he had also a passion for building, and was a man of rare taste as an architect. The Agra Fort, whose stern walls of red sandstone extend about a mile and a half, represents to us, at present, not strength and protection, but an enclosure within which the emperor built his great palace, which is a marvel of beauty and of superb architectural workmanship. The most attractive of the many parts of this palace is the Pearl Mosque, which "owes its charm to its perfect proportions, its harmony of designs, and its beauty of material, rather than to richness of decoration and ornament. In design it is similar to most temples of this kind; a court-yard with a fountain in the middle, surrounded on three sides by arcaded cloisters; while on the entrance side and that facing it are exquisitely chaste marble screens." "Into the fair body of the India marble the Moguls could work designs and arabesques borrowed from the Persia of ancient history, and flowers of exquisite hue and symmetry suggested by the more advanced and civilized Florentine artists, who were tempted over by the well-filled coffers of Shah Jehan." As the Pearl Mosque was a part of the palace, it was only used by the royal court. Days of pleasure and improvement could be spent in the study of the various parts which have been preserved of this ancient palace. But we pass on a few miles to the Taj Mahal, which, like most of the best buildings of Mohammedan art in North India, is a mausoleum and was erected by Shah Jehan to his favourite wife, Mumtaz-i-Mahal. The Taj is erected in a beautiful garden, the gateway into which is perhaps the finest in India and is "a worthy pendant to the Taj itself." The garden is exquisitely laid out, with a view to setting off the unspeakable charms of that "dream of loveliness embodied in white marble." The Taj has well been described as a work "conceived by Titans and finished by jewellers." The grandeur of the conception and the wonderful delicacy of the workmanship cannot fail to impress even the most unlearned in the architectural art. Much has been written,
