Nor, on the art side of our own country, must we overlook the Historical division, the perfecting of which has been a labor of love with Mr. Etting. He allots space among the old Thirteen, and reserves a place at the feast of reunion to the mother of that rebellious sisterhood. Forty acres of "floor-space" _sub Jove_ remained to be awarded to foreign and domestic claimants. Gardening is one of the fine arts. Certainly nothing in Memorial Hall can excel its productions in richness, variety and harmony of color and form. Flower, leaf and tree are the models of the palette and the crayon. Their marvelous improvement in variety and splendor is one of the most striking triumphs of human ingenuity. A few hundred species have been expanded into many thousand forms, each finer than the parent. It is a new flora created by civilization, undreamed of by the savage, and voluminous in proportion to the mental advancement of the races among whom it has sprung up. Progress writes its record in flowers, and scrawls the autographs of the nations all over Lansdowne hill. No need of gilded show-cases to set off the German and Germantown roses, the thirty thousand hyacinths in another compartment, or the plot of seven hundred and fifty kinds of trees and shrubs planted by a single American contributor. The Moorish Kiosque, however, comes in well. The material is genuine Morocco, the building having been brought over in pieces from the realm of the Saracens, of "gul in its bloom" and of "Larry O'Rourke"--as Rogers punned down the poem of his Irish friend. The nations comfortably installed, we must sketch the tactical system under which they are drawn up for peaceful contest. The classification of subjects adopted by the Commission embraces seven departments. Of these, the Main Building is devoted to I. _Mining and Metallurgy_; II. _Manufactures_; III. _Education and Science_; Memorial Hall and its appendages, to IV. _Art_; Machinery Hall, to V. _Machinery_; Agricultural Hall, to VI. _Agriculture_; and Horticultural Hall and its parterres, to VII. _Horticulture_. These habitats have, as we have heretofore seen, proved too contracted for the august and expansive inmates assigned them. All of the latter have overflowed; mining, for instance, into the mineral annex of thirty-two thousand square feet and the great pavilion (a hundred and thirty-five feet square) of Colorado and Kansas; education into the Swedish and Pennsylvania school-houses and others already noted; manufactures into breweries, glass-houses, etc.; and so on with an infinity of irrepressible outgrowths.
