Newstadt and Ratisbon on the Danube, it stretched L_ across hills, valleys, rivers, and morasses, as far as Wimpfen on the Necker, and at length terminated on the banks of the Rhine, after a winding course of near two hundred miles ". This important barrier, uniting the two mighty streams that protected the provinces of Europe, seemed to fill up the vacant space through which the barbarians, and particularly the Alemanni, could penetrate with the greatest facihty into the heart of the empire. But the experience of the world from China to Britain, has exposed the vain attempt of for- tifying any extensive tract of country An active enemy, who can select and vary his points of attack, must, in the end, discover some feeble spot, or some un- guarded moment.
