Beni-Saf, Mostaganem, Tenes, Shershell, Dellys, Bougie, Cello, and La Calle, still await the branches that are to connect them with the trunk line. These, however, have all been either begun or at least projected. All the companies have received Government aid by advances and concession of land. Yet in certain places, especially between Algiers and Blida, and on the Philippeville-Constantine section, the local traffic has already begun to yield ample returns on the capital originally invested. The tariff is everywhere very high, sufficient interest on the outlay being guaranteed by the Government to render the companies independent of the

South of the great central artery, three lines already penetrate to the plateaux in the direction of the Sahara. One of these runs from Constantine to Batna, another from Saida to Mesheria, and the third from Sidi-bel-Abbes to Ras-el-Ma, Thanks to these new means of communication, colonisation may now be diffused throughout the plateaux better than in the regions lying between Aumale and Laghwat.
