The observations, however, which Signor Della Cella has made on the map of Northern Africa by Arrowsmith, respecting the extension of the Gharian chain towards the Greater Syrtis, and the omission of the low range which actually branches off from those mountains, are certainly very correct[16]. For a minor branch of the Gharian detaches itself from the chain, and runs down to the sea in the neighbourhood of Lebida; and another part of the same range extends itself from Lebida towards the Syrtis Major, gradually declining as it approaches that place, both of which are omitted in the map to which the Doctor has alluded[17]. The eastern extremity of the Gharian chain appears also to be carried too near to the Greater Syrtis, from no part of which (so far as our experience went) could any portion of this chain be perceived. We were unable to discover any remains of antiquity at Mesurata; but its remarkable position between the fertile regions of the Cinyphus, and the barren dreary wastes of the Greater Syrtis, cannot fail to make it an object of more than common interest to those who witness the singular contrast. From the high range of sand-hills, which we have mentioned above, between the town and the sea, an excellent idea may be formed of this striking peculiarity of situation; and we often toiled up their steep and yielding sides to enjoy the singularity of the prospect. At the foot of these masses, to the southward, and to the westward, are the varied and cultivated lands of Mesurata[18]: there are seen endless groves of palm-trees and olives, among which are scattered numerous villages and gardens, rich tracts of corn land, flocks of sheep and goats, and everywhere a moving and busy population. To the eastward[19], a tenantless and desolate waste, without a single object rising from its surface, lies stretched in one long, unbroken, line, as far as the eye can range. Not a single tree or shrub is on that side to be seen; not a single house or tent, not a single human being, or animal of any description. In fact the effect of the Greater Syrtis, from this place, is that of a dreary moor—a wide tract of level, waste land—without anything to distinguish one part of it from another but the windings of a marsh, which threads its dark surface, and is lost in different parts of the unbroken horizon[20].
