So that the difference in favor of Paris is 327,127 feet. In round numbers, the Paris Exposition building is one-fifth larger than the united areas of the five principal buildings at the Centennial. Without making a close calculation of the areas of the annexes and detached buildings either of Philadelphia or Paris, I am disposed to think that the 1876 Exhibition was not in excess of the present one in this respect. Either exceeds, both in the main buildings and the swarm of detached structures, any preceding exhibitions. The difference between the Paris exhibitions of 1867 and 1878 is as 153 is to 240: the London building of 1862 would bear to both the proportion of 92, without any important annexes.

The high ground on the right bank of the Seine is occupied by the Trocadéro Palace, which faces that on the Champ de Mars, each building being about five hundred yards from the bank of the river, which flows in so deep a depression that it is visible from neither building, and the grounds between the two appear to be continuous, though the bridge suggests the contrary.

The cascade in front of the Trocadéro occupies the site of the old steps by which the steep hill was ascended, but the ground nearer to the Seine has been so raised that the river-roads on each side run in subways spanned by bridges, thus permitting free use of the great thoroughfares without impeding communication between the two portions of the Exposition. Indeed, they appear as one viewed in either direction, notwithstanding the intervening streets and wide and rapid river.

The change in the shape of the Trocadéro hill to bring it into a symmetrical position in front of the Champ de Mars has required the quarrying of twenty-four thousand cubic mètres of rock, leaving a rough scarp on the northern edge quarried into steps, walks and grottos, with flowers, ferns and mosses cunningly planted on the ledge and creepers on the walls.

The Trocadéro Palace is the most striking architectural feature of the Exposition. Standing on a level one hundred and six feet above the Quai de Billy and overlooking the city of Paris, the dome and glittering minarets of the building are visible from many miles' distance. It is not easy to describe its architecture, though it is called "half Moorish, half Renaissance;" which is not very definite. It has a large rotunda capable of accommodating seven thousand persons, and the river-front has two spacious corridors on as many stories. The central building is flanked by two tall square campaniles, and from its sides extend long wings which curve toward the river: these have colonnades and terraces in front overlooking the garden, its picturesque and grotesque cottages and pavilions, its fountains and its parterres of gay flowers.

The Trocadéro has been purchased by the town council of Paris, and is to be a permanent structure, its flanking salons, forty-two feet wide, being known as "Galéries de l'Art Rétrospective." Its collection is to form a history of civilization, and will probably include the Egyptian, Assyrian and similar collections from the Louvre, as well as the Ethnological, which is at St. Germain. It is designed to represent in chronological order ancient and historic art, both liberal and mechanical, with the furniture, arms and tools of the Middle Ages and Renaissance, arms, implements and fabrics from the East, Africa and Oceanica, and a collection of musical instruments of all ages and countries. This is an ambitious programme, but will no doubt be well accomplished. Its general color is that of the beautiful stone of this region, a delicate cream. The uniformity is broken by great boldness and variety in the structural form of the[page 158] building, and by its pillars, deep colonnades and heavy cornices, giving shadows which prevent monotony of tint.

While artists and architects disagree like the proverbial doctors, and purists shudder at the jumble of orders, periods and nationalities, a tyro may well hesitate. An opinion of the building will no more suit everybody than does the building itself; but one cannot entirely forfeit one's reputation for taste, for each will find some agreeing judgments. All must acknowledge that it has a gala air. Its central dome, tall minarets and wings widespread toward the river crown the height and seem to foster the beauties they partly enclose.

The circular corridor of the rotunda is surmounted by the Muses and other figures typical of the future purposes of the building. The rotunda-walls are themselves castellated, the towers being interplaced with windows of Saracenic arched form. The béton pavement of the corridors and balcony is made of annular fragments, facets upward, of black, red, white and slate-colored marbles, feldspar and other stones. It is as hard as natural rock and as smooth as half-polished marble. A tessellated fret pattern is made along the borders of the corridor floor, consisting of triple rows of smooth cubes of marble inserted in the cement. The square balusters are of red-mottled marble, with base and entablature of dull rose. The square corner pillars support figures allegorizing the six divisions of the earth.

The vestibules at the sides of the tower are open east and west for the passage to and from the garden, and at the sides have doors which admit to the Grande Salle and the flanking galleries respectively. The interior red scagliola columns of the vestibule are in pairs, with white bases and capitals, the latter combining the lotus-leaf with the volute. The soffits of the ceiling have panels of yellow with orange border, contrasting with iron beams painted a chocolate brown.

The uniformity of the long and curved colonnades which form the wings of the building is broken by square porticoes, which have entrances to the galleries and small terraces in front, with steps leading to the garden. The wall back of the white pillars of this long promenade is painted of a warm but not glaring red. The roof is of tile and skylight. The base of the colonnade beneath the balustrade and pillars is a rough concrete wall hidden by a sloping bank of evergreens, upon which the eye rests pleasantly amid so much wall-space and architectural decoration.
