[Illustration: STATUE OF FREDERICK THE GREAT, BERLIN, GERMANY.--This impressive and masterly work was erected in 1851 at one end of the "Linden," and is probably the grandest monument of its kind in Europe. The great King is represented on horse-back, with his coronation-robes and walking-stick. The pedestal is divided into four sections. The upper one contains allegorical figures and scenes in Frederick's life, with the figures Moderation, Justice, Wisdom and Strength at the corners; the second section contains figures of the King's officers, and the lower section, the names of other distinguished men.] [Illustration: THE BRANDENBURG GATE, BERLIN, GERMANY.--The Brandenburg Gate, forming the entrance to Berlin, from the Thiergarten, was erected in 1793 in imitation of the Propylaea at Athens. It is 85 feet high and 205 feet wide, and has five different passages, separated by massive Doric columns. It is at the one end of "Unter den Linden," and its middle passage is reserved for royal carriages only. The material is sandstone, and it is surmounted by a Quadriga of Victory from copper, taken to Paris by Napoleon in 1807, but restored in 1814. On the side are two wings resembling Grecian Temples, one of which is a pneumatic post-office and the other a guard-house. Both combine in their construction, strength, elegance and beauty.] [Illustration: MONUMENT OF VICTORY, BERLIN, GERMANY.--This monument, rising to a height of two hundred feet, stands on a circular terrace, approached by eight granite steps in the Thiergarten. It was dedicated on September 2, 1873, to commemorate the great victories of 1870 and 1871. The massive square pedestal is adorned with reliefs in bronze. Above, in the flutings of the column, which consists of yellow, grayish sandstone, are placed three rows of Danish, Austrian and French cannon, captured in the different battles fought with those nations.] [Illustration: THE HISTORIC WINDMILL, POTSDAM, GERMANY.--Potsdam is almost entirely surrounded by a fringe of royal palaces, parks and pleasure-grounds. Here is located the palace of Sanssouci. Adjacent to the palace is the famous windmill, now royal property, which its owner refused to sell to the King, meeting threatened violence by an appeal to the judges of its supreme court.] [Illustration: MADONNA DI SAN SISTO (BY RAPHAEL), DRESDEN GALLERY, DRESDEN, GERMANY.--This masterpiece of Raphael, was photographed direct from the original painting, worth $400,000. It is an altar-piece, representing the Virgin and Child in clouds, with St. Sixtus on the right, St. Barbara on the left, and the cherubs beneath. A curtain has just been drawn back, and the Virgin issues, as it were, from the depth of Heaven, her large serene eyes seeming to embrace the whole world in their gaze. The most striking feature of the painting is the expression of naive innocence depicted on the faces of the cherubs.] [Illustration: MAGDALENE (BY BATTONI), DRESDEN GALLERY, DRESDEN, GERMANY.]
