The Department of Coins has 200,000 specimens, many very old and rare; and that of Northern Antiquities illustrates with great fulness the prehistoric and Roman periods. The Cabinet of Engravings is extremely interesting, and has some specimens of very great value; but it is open to the general public for a few hours on Sunday only, and even then the greater part of its collections is reserved to art students, who have the entire monopoly of its treasures on other days of the week. It well repays persistent effort, however, to make a few quiet visits to this rare cabinet. Some of the finest works are hung on the walls of the pleasant rooms.

The famous mural paintings by Kaulbach adorning the upper staircase walls of the New Museum are widely admired, but critics differ in the estimate of their place as works of art. The upper saloons reached by this staircase show the cartoons of Cornelius, and foreshadow a grandeur in German art not yet realized.

The third building in the group which holds the chief art treasures of Berlin is the National Gallery, its pictures partaking, as such a collection should, strongly of the German spirit as shown in modern German art. The paintings are of various degrees of merit, many being of value chiefly as reflecting the national life. A fine portrait of Mommsen arrested me, on one visit; a striking picture, "Christ healing a Sick Child in its Mother's Arms," by Gabriel Max, was a continual favorite; and many others were among those to which we went frequently and before which we lingered long.

The crowning excellence of all the Royal Art Collections is their singular method and completeness. The Old Museum, especially, in its arrangement and illustration of the history of painting in all schools, is without a peer, and it is particularly rich in the early Italian masters. The National Gallery in London has been compared in arrangement with the Berlin Museum, but our observation showed nowhere else in Europe so great facility for systematic study of art as here.

Quite recently, a writer in the "London Art Journal," in comparing European art galleries, characterizes the Italian galleries, except the Pitti, as mere storehouses of pictures, so great have been the accessions, in late years, of altar-pieces from suppressed convents; while, on the other hand, the Louvre, and the galleries of Munich, Dresden, Vienna, St. Petersburg, and Madrid still retain their original characteristics as collections made by persons of taste and discrimination. "The Berlin Gallery," says this writer, "is neither a storehouse nor a collection. It stands on a footing of its own. The studious and organizing Prussian mind soon handed over the management of all its collections to a body of specialists, trained to study the objects in their keeping and to arrange them not so much for the delight as for the information of a studious public. The Berlin Gallery has been thus arranged, and its additions have been purchased under the direction of scholars and historians rather than artists and dilettanti. Historical sequence and historical completeness have been aimed at. The collection is intended to exemplify the development of the art of painting in mediæval and renascence Europe. It is impossible to enter the Museum gallery and not be struck with this fact. The visitor finds himself turned into a student of the history of painting, as he wanders from room to room. The ordering of the pictures, the information contained in the catalogue,—everything points in the same direction. So clearly has the Museum come to be understood at Berlin as a kind of art-history branch of a university, that a portion of the funds devoted to it is annually spent upon the publication of a periodical universally recognized as the leading magazine in the world devoted to the history of art. By means of it, students in all countries are informed from year to year of the new acquisitions and discoveries made by the staff of the Museum, or by the leading authors and students of the subject, of all nationalities. The Berlin collection has thus won for itself a place as the historical collection par excellence."

The Museums are under the care of a Director-General, with nine or more Directors of Departments. Dr. Julius Meyer, Director of the Picture-Gallery, is said to be probably unequalled by any living writer for a wide and philosophic grasp of the whole subject of Art History, to which his life has been devoted; while the names of distinguished scholars and professors at the head of the other departments are guaranties of similar excellence. A series of four illustrated volumes is now in process of publication, which will present, in photographs and engravings, large or small, every picture of importance in the gallery. The text of these volumes, by Drs. Meyer and Bode, will be extremely valuable, and the whole will doubtless stand foremost among publications designed as exponents of European galleries.

The fine and massive building of the Arsenal, opposite the palace of the late Crown Prince, dates from the time of Frederick I., last of the Electors and first of the Prussian Kings. The grand sculptures of the German artist Schlüter, who was afterwards called to the aid of Peter the Great in the creation of St. Petersburg, adorn the exterior of the edifice. Any chance walk along the Linden will arrest the attention to this building, with the remarkable heads of dying warriors carved in the keystones of its window arches. In the renovation of the Arsenal a few years since, no improvement was made on the exterior, except to remove the accumulations of smoke and dust which a hundred and seventy years had deposited there. After the close of the Franco-Prussian War, it was the thought of the aged Emperor to make this Arsenal, already crowded with an immense collection of arms, armor, and trophies, into a kind of Walhalla,—a National Hall of Fame. This was fully carried out. In rooms on the ground floor one may read the whole history of ordnance, old and new, including the famous Armstrong and Krupp guns. A portion of this floor is devoted to models of fortresses, plans of battles, and captured flags. There is a war library; and the celebrated pictures of the Giant Grenadiers, painted with his own hand by Frederick William I., father of Frederick the Great, are also to be seen.

A magnificent double staircase under a glass roof leads to the second floor (in Germany called the first), where one portion is devoted to an interesting collection of arms, which is, however, inferior to those of one or two other European cities. The chief attraction to the visitor, as well as a permanent magnet to the patriotic Berlinese, who come hither in whole families, is the "Hall of Fame," consisting of three sections, all splendid in mosaic floors and massive marble pillars, and adorned with sculpture and fine historical frescos. One of the latter represents the Coronation of the first King of Prussia at Königsberg, and another has for its subject the Proclamation of the German Empire at Versailles. The Central Hall is adorned with bronze statues of the Great Elector, of the Fredericks and Frederick-Williams of the Prussian royal line, and of the Emperor William I. The "Halls of the Generals," on either side of this "Hall of the Rulers," have busts of the military leaders, including a fine one of the Crown Prince. Here are also several historical paintings; prominent among which are "The Battle of Turin," "The Emperor William and the Crown Prince at Königgrätz," and "The Capitulation at Sedan."

Perhaps no collection, among many more which might be mentioned, better illustrates the practical working of the German mind than the Royal Post Museum in the Leipziger Strasse. Here is shown everything of interest connected with the transmission of intelligence, and poetry as well as prose has entered into the heart of this Government exhibit. On the walls of the first saloon entered by the visitor are copies in stone of Assyrian bas-reliefs showing a warrior with chariot and arrows. This suggests to us a scene in the lives of David and Jonathan; but communication by means of arrows is probably much older than the time of David. Earlier than even the Assyrian stone must have been the model for the Egyptian wicker and wooden post-chariot. In this room, under a glass case, is an exquisite marble statuette, found at Tanagra, of a Grecian girl seated, and writing on a tablet; and not far away is a Roman warrior, carrying his message. Entering the next hall, we pass a beautiful bronze statue of Philip, the Grecian soldier, bearing a laurel spray, stretching his athletic limbs in breathless strides as he goes toward the capital to announce the battle of Marathon, and to fall dead on his entrance to the city, with the single word "Victory!" on his lips. Here on the walls are four emblematic pictures: "The Land-Post," representing a knight with a sealed missive in his hand, standing beside and curbing his fiery steeds; "The Sea-Post," showing a mail-carrier on the back of a dolphin in the midst of stormy waves far out at sea; "The Telegraph," with Jove and his lightnings as its central figure: and "The Rohrpost,"—a maiden, blowing into an orifice with "the breath of all the winds." This last is emblematic of that postal arrangement in Berlin by which letters and postal cards are sent with great speed through pneumatic tubes from which the air is exhausted by means of pumps, and which makes it possible to receive a written message from a distant part of the city within a few minutes after it is written.

Among the ancient representations are models of the boats in which the old Norsemen sailed the seas, and of those by which our Anglo-Saxon ancestors invaded England from Germany. These are strikingly contrasted, in their simplicity and clumsiness, with a fully equipped model, from four to six feet long, of a modern North German Lloyd Atlantic mail steamship, than which no better equipped boat sails the main. One goes on, past a Gobelin tapestry representing a mail-scene at Nüremberg in the Middle Ages, through long halls and corridors where are hundreds of models of post-office buildings of the most convenient and approved plans, in all parts of the world. These are of every variety of architecture, from the great general post-office in London, the handsome Hanover post-office building, those of the central and district post-offices in Berlin, Dresden, Cologne, Heidelberg, and many others in South Germany, to the modern edifices which adorn, and yet seem strangely out of keeping with, the picturesque old North German towns. These models are miniature copies of the exteriors of post-office buildings, varying in length from one and a half to six or eight feet, and of corresponding height. One most interesting model shows the interior of a modern post-office, each floor showing an exact copy of its department of the service, with all appliances and conveniences.
