It is common for 15,000 visitors to attend these Thursday night firework exhibits. Colored electric light jets deck the fountains, flower-beds, and halls. Crystal Palace was designed by Sir Joseph Paxton, and cost seven and a half million of dollars. Well may it be called London's Paradise. Shall we say that the greatest piece of constructive architecture of any country is that of Eiffel Tower! Situated on the left bank of the Seine River, it overlooks Paris and the country for fifty miles around. In its construction, iron caissons were sunk to a depth of forty-six feet on the river side, and twenty-nine and one-half on the other side. When the water was forced out of these caissons by means of compressed air, "concrete was poured in to form a bed for four massive foundation piers of masonry, eighty-five feet thick, arranged in a square of 112 yards. Upon this base which covers about two and a half acres rises the extraordinary, yet graceful structure of interlaced ironwork" to a height of 984 feet. Eight hundred persons may be accommodated on the top platform at once. It was completed within two years' time, and is the highest monument in the world. Washington monument ranks second, being 555 feet high. From the summit of Eiffel Tower one may secure a good view of Paris, her public buildings, chief hills, parks, and boulevards, monuments, and embankments. An imitation of Trajan's column in Rome, is 142 feet in height, and thirteen feet in diameter. It is constructed of masonry, encrusted with plates of bronze, forming a spiral band nearly 300 yards in length, on which are represented the "battle scenes of Napoleon during his campaign of 1805, and down to the battle of Austerlitz. The figures are three feet in height and many of them are portraits. The metal was obtained by melting down 1,200 Russian and Austrian cannons. At the top is a statue of Napoleon in his Imperial robes. This column reflects the political history of France." The design sculptor is Bergeret. For their antiquity the mummies and statues in the Egyptian galleries of the British Museum are very interesting. They embrace the period from 3600 years before Christ to 350 A.D. "The tomb of Napoleon by Visconte," and "the twelve colossal victories surrounding the sarcophagus by Pradier," are among the finest works of Parisian sculpture. The sarcophagus, thirteen feet long, six and one-half feet high, consists of a single huge block of reddish-brown granite, weighing upwards of sixty-seven tons, brought as a gift from Finland at a cost of $700,000. The Louvre, Paris, contains one of the finest art galleries in Europe, and with the Tuilleries, covers about eight acres, "forming one of the most magnificent places in the world."
