In the Crystal Palace Gardens, the Italian style has not been servilely copied, but rather adapted and appropriated. It has been taken, in fact, as the basis of a portion of our garden, and modified so as to suit English climate and English taste. Thus, we have the terraces and the architectural display, the long walks, the carefully cut beds, and the ornamental fountains: but the undulations of greensward, that bespeak the English soil, give a character to the borrowed elements which they do not find elsewhere. The violent juxtaposition of the two styles of gardening--the Italian and the English--it may readily be conceived, would produce a harsh and disagreeable effect. To avoid the collision, Sir Joseph Paxton has introduced, in the immediate vicinity of the terraces and the broad central walk, a mixed or transitional style, combining the formality of the one school with the freedom and natural grace of the other; and the former character is gradually diminished until, at the north side of the ground, it entirely disappears, and English landscape-gardening is looked upon in all its beauty. THE TERRACES. Descending the steps we reach the first terrace, on the parapet of which are placed twenty-six allegorical statues of the most important commercial and manufacturing countries in the world, and of the chief industrial cities of England and France. The length of the upper terrace is 1576 feet, and its width 48 feet; the terrace wall is of Bath-stone. The granite pedestals on each side of the steps, leading from the Great Transept, are 16 feet by 24 feet. The width of the central flight of steps is 96 feet; and this is also the width of the grand central walk. The lower terrace, along which are ranged the first six fountains of the upper series, is 1664 feet long between the wings of the building, or nearly one-third of a mile, and 512 feet wide, the basins for the fountains on this terrace being, in their measurements, as before stated, all multiples of eight. The total length of the garden front of the wall of this terrace, which is formed into alcoves, is 1896 feet. The length of the broad central gravel walk from the building to the end of the garden in a direct line is 2660 feet. Such are a few of the principal measurements connected with the Palace Gardens, as these are seen on the surface. But although the work that is above ground may be recognised and calculated with little trouble by the visitor, there is beneath the surface an amount of labour and capital expended, of which he can with difficulty form an accurate idea. Drain pipes spread under his feet like a net-work, and amount in length to several miles; he treads on thousands of bundles of faggots which have formed his path; he walks over ten miles of iron piping which supply the fountains for his amusement.
