The New Town of Edinburgh is separated from the Old Town by the ravine of the North Loch, over which are thrown the bridges by which the two towns are connected. The loch has been drained and is now occupied by the Public Gardens and by the railway. The New Town is substantially the work of the last half of the past century and the first half of the present one--a period which sought everywhere except at home for its architectural models. In some of the recent improvements in the Old Town very pretty effects have been produced by copying the better features of the ancient dwellings all around them, but the grandiloquent ideas of the Georgian era could not have been content with anything so simple and homespun as this. Its ideal was the cold and pompous, and it succeeded in giving to the New-Town streets that distant and repellent air of supreme self-satisfaction which makes the houses appear to say to the curious looker-on, "Seek no farther, for in us you find the perfectly correct thing." The embodiment of this spirit may be seen in the bronze statue of George IV. by Chantrey, in George street: the artist has caught the pert strut so familiar in the portraits, at sight of which one involuntarily exclaims, "Behold the royal swell!" [Illustration: THE NORTH BRIDGE.] But the New Town has two superb features, about whose merits all are agreed: we need hardly say these are Princes street and the Calton Hill. Princes street extends along the brow of the hill over-hanging the ravine which separates the two towns, and which is now occupied by public gardens: along their grassy slopes the eye wanders over trees and flowers to the great rock which o'ertops the greenery, bearing aloft the Castle as its crown, while from the Castle the Old Town, clustering along the height, streams away like a dark and deeply-colored train. The Calton Hill offers to the view a wide-spreading panorama. At our feet are the smoking chimneys of Auld Reekie, from which we gladly turn our eyes to the blue water and the shores of Fife, or seek out in the shadow of Salisbury Crags and Arthur's Seat the tottering arch of Holyrood Abbey. The hill is well dotted over, All up and down and here and there, With Lord-knows-what's of round and square; which on examination prove to be monuments to the great departed. A great change has taken place in the prevalent taste since they were erected, and they are not now pointed out to the stranger with fond pride, as in the past generation. The best one is that to Dugald Stewart, an adaptation, the guide-books say, of the Choragic Monument of Lysicrates. The all-pervading photograph has made it so familiar that it comes upon one as an old friend.
