On the southern side of the great plain there is a remarkable correspondence with the northern border in the constitution of the mountain masses, and an interesting difference in the manner in which they are disposed. On the north you have first a single mountain, and then a mountain system; on the south the line commences with a mountain system and ends with a single mass. On the north the mountain system steps out in advance of the mountain; on the south, by a happy reversal of the order, the mountain stands forward alone. Alagöz and the belt south of Lake Sevan are answered by the Ararat system and by the fabric of Ararat. The range which I have termed the Ararat system is known in the country under the name of Aghri Dagh, a name which is equally applied to Ararat, but of which the roughness on the palate appears to express with greater felicity the rugged character of the system to which Ararat belongs. From the wild and mountainous country which, about the 42nd degree of longitude, borders the right bank of the Upper Araxes before it enters the plain of Pasin, there extends across the plateau in an easterly direction a long and comparatively narrow range, which, skirted on the one side by the course of the Araxes, and on the other by the plain of Alashkert, composes the spine of this central region of the tableland, and is interposed as a barrier between north and south. The appearance of the chain presents a striking contrast to the convex shapes which feature the adjacent landscapes; the sides are abrupt, the summits sharp, and the peaks rise from deep valleys to a height which reaches over 11,000 feet. Where the Araxes leaves the narrows near the town of Kagyzman, this range is seen massed upon the right bank of the river; and after following the stream along the 40th degree of latitude, it inclines to the south-east. Aided by this slight inclination in the direction of its southern barrier, the valley rapidly expands, and attains its greatest dimensions at a point just south of Alagöz. It is at that point that the western slope of Ararat, which has risen in advance of this satellite system from a low cape in the west, begins to gather in height and volume, concealing the rough features of these obsequious mountains behind the royal sweep of a long train.
