of a nation, its progress in the arts, its scientific acquirements, its literary culture, have a direct and absolute dependence upon its material prosperity and the independent pecuniary circumstances of its scholars and learned men. While poverty is often an incentive to that perseverance which insures success, it is a condition which only affects individual and not national development. Without leisure, there can be no studies; without studies, no advance. Another factor of paramount importance in the evolution and maintenance of civilization, and one to which the Hebrew was deeply indebted, was the wide and varied experience derived from cosmopolitan habits and associations. This intercourse was facilitated by the easy and rapid means of international communication at the disposal of the Jewish trader. The Mediterranean, which washed the shores of three great continents, presented no obstacles to the enterprise of the Phœnicians, whose intimate connections with the Jews gave the latter advantages enjoyed by no other people; and the fabled monsters invented by those astute navigators to damp the ardor of other maritime adventurers, and which survive in the traditions of classic mythology, possessed no terrors for the allies and friends of the Tyrian merchants and sailors. No area of equal extent in the world offered so diversified and instructive a spectacle of human life and manners as the winding coast of that great inland sea. With its cities and its kingdoms, founded under different political conditions, living under different systems, governed by different laws, frequent and prolonged visits had early made the Jew familiar. To the audacious navigator who had sailed over the mysterious Ocean, far beyond the Pillars of Hercules, the coasting of the Mediterranean was a trifle. In subsequent times the military highways of the Roman Empire--whose construction, the first work after the invasion of a country destined to subjection, indicated the fate of its people, and insured their obedience with far more certainty than the fortified camps of the legions--afforded the Hebrew merchant easy access to the utmost limits of the vast region subject to imperial authority. But it was not only in lands generally accessible to commercial enterprise that the mercantile and intellectual activity of the Jew was displayed. With the periodical caravans he traversed the Arabian Peninsula, and braving the perils of the Desert--the stifling heat, the sand-storms, the robbers who thrived amidst its desolation--collected and distributed the precious commodities of Yemen. He penetrated to the centre of Ethiopia; his costume and his wares were known to the inhabitants of every city on the Red Sea and the Persian Gulf. The coast of Britain was visited by Jews long before the invasion of Cæsar. The restless, adventurous spirit, so universal that it became a national characteristic fostered through untold generations, and the extensive and profound
