II.
THE LAND OF THE CORSAIRS.
It is time to ask how it was that a spacious land seemed to lie vacant for the Corsairs to occupy, and a land too that offered almost every feature that a pirate could desire for the safe and successful prosecution of his trade. Geographers tell us that in climate and formation the island of Barbary, for such it is geologically, is really part of Europe, towards which, in history, it has played so unfriendly a part. Once the countries, which we now know as Tunis, Algiers, and Morocco, stood up abruptly as an island, with a comparatively small lake washing its northern shore, and a huge ocean on the south (see [the map]). That ocean is now the Sahra or Sáhara, which engineers dream of again flooding with salt water, and so forming an inland African sea. The lake is now the Mediterranean, or rather its western basin, for we know that the Barbary island was once nearly a peninsula, joined at its two ends to Spain and Sicily, and that its Atlas ranges formed the connection between the Sierra Nevada and Mt. Aetna. By degrees the Isthmus between Cape Bona and Sicily sank out of sight, and the ocean flowed between Spain and Africa, while the great sea to the south dried up into the immense stony waste which is known preëminently as the Sahra, the Desert, “a tract of land, bare as the back of a beast, without trees or mountains.”
Through one or both of these narrow straits, Gibraltar and Malta, all vessels from the outer ocean bound for the ports of France and Italy and the Levant, were obliged to pass; and it must be remembered that just about the time when the Corsairs made their appearance in Barbary, the riches of the new-found Western world were beginning to pour through the straits to meet those of the East, which were brought to France and Spain, England and Holland, from Alexandria and Smyrna. An immense proportion of the trade of Europe had to cross the western basin of the Mediterranean, of which Barbary formed the southern boundary. Any bold man who could hold Tunis at the eastern corner, or Algiers in the middle, or Ceuta or Tangiers at the western point, might reckon upon numerous opportunities of stopping argosies of untold wealth as they passed by his lair. The situation seemed purposely contrived for Corsairs.
