30 A TROPICAL DEPENDENCY mountain by which the expedition entered Europe bears to this day the name of the military commander — the Mountain of Tarik, Jebr el Tarik or Gibraltar — while the spot, a little further along the coast, on which a lesser detachment landed, is known as Tarifa from the name of its leader Tarif, another of Musa's Berber freedmen. What is not perhaps so generally recognised is that the men who led this civilising expedition into Spain were of the same race as those who, driven by the same compelling cause to another fate, carried the banner of civilisation into Negroland. The capacity for taking high command which Musa recognised in the Berbers was a capacity of race which was sure to find its satisfaction under circumstances of the most diverse kind. North or south, it mattered little in which direction they were forced by the resistless pressure of a higher fate. Alike in Spain and Negroland, where they went in misfortune they were to remain in triumph, until that mysterious decadence which attends the fate of peoples marked them for decay.
