On emerging from the valley of Sélem a fertile tract of high ground presents itself, which lies between the valley and Lebida; clusters of olive-trees are scattered over its surface, and contribute with the green turf on which they are planted to give it a very pleasing appearance. From the summit of this appears the whole plain of Lebida, stretching down, in a gentle slope, from the high ground to the sea; and a more beautiful scene can scarcely be witnessed than that which is presented by this fine tract of country. Thick groves of olive and date-trees are seen rising above the villages which are scattered over its surface; and the intermediate spaces are either covered with the most luxuriant turf, or rich with abundant crops of grain. It must always afford matter for surprise to those who are acquainted with this beautiful and highly-productive country, how Tripoly could ever have been selected, in preference to Lebida, as the metropolis of the regency. Placed in the midst of sand, on the borders of an extensive desert, and situated almost at the extremity of the country in which it stands, Tripoly appears to enjoy scarcely any particular local advantage beyond the possession of its port; while Lebida seems to unite in one beautiful spot all the advantages of plenty, convenience, and security. It is probable that the harbour and strong walls of Tripoly were the principal causes of its adoption as the capital; and the sums of money which would be necessary to rebuild and fortify Lebida, might have been considered as more than equivalent to its local recommendations, by a people who seldom look beyond the present. But Lebida, once occupied, would be a much stronger post than Tripoly could ever be made; and the good sense of the ancients was conspicuously manifested in its selection as a principal town.
