The buildings of Damascus are almost all of snowy whiteness, and this contrasts well with the surrounding foliage. The gardens and orchards, which have been so long and so justly celebrated, encompass the city, and extend on both sides of the Barada some miles eastward. They cover an area at least twenty-five miles in circuit, and make the environs an earthly paradise. The varied tints of the foliage, and of the blossoms and fruit in their season, greatly enhance the beauty of the picture. The sombre hue of the olive and the deep green of the walnut are finely relieved by the lighter shade of the apricot, the silvery sheen of the poplar, and the purple tint of the pomegranate; while lofty cone-like cypresses appear at intervals, and a few palm-trees here and there raise up their graceful heads. The variously coloured foliage thus surrounding the bright city, and the smooth plain beyond, now bounded by naked hills, and now mingling with the sky on the far-distant horizon, and the wavy atmosphere that makes forest, plain, and mountain tremble, give a softness and an aerial beauty to the whole scene that captivates the mind of the beholder.
