rail or one by road. Now, the North not only enjoyed enormous advantages in sea-power, both mercantile and naval, but in road, rail, canal, and river transport too. The road transport that affected both sides most was chiefly in the South, because most maneuvering took place there. "Have you been through Virginia?—Yes, in several places" is a witticism that might be applied to many another State where muddy sloughs abounded. In horses, mules, and vehicles the richer North wore out the poorer and blockaded South. Both sides sent troops, munitions, and supplies by rail whenever they could; and here, as a glance at the map will show, the North greatly surpassed the South in mileage, strategic disposition, and every other way. The South had only one through line from the Atlantic to the Mississippi; and this ran across that Northern salient which threatened the South from the southwestern Alleghanies. The other rails all had the strategic defect of not being convenient for rapid concentration by land; for most of the Southern rails were laid with a view to getting surplus cotton and tobacco overseas. The strategic gap at Petersburg was due to a very different cause; for there, in order to keep its local transfers, the town refused to let the most important Virginian lines connect. Taking sea-power in its fullest sense, to include all naval and mercantile parts on both salt and fresh water, we can quite understand how it helped the nautical North to get the strangle-hold on the landsman's South. The great bulk of the whole external trade of the South was done by shipping. But, though the South was strong in exportable goods, it was very weak in ships. It owned comparatively few of the vessels that carried its rice, cotton, and tobacco crops to market and brought back made goods in return. Yankees, Britishers, and Bluenoses (as Nova Scotian craft were called) did most of the oversea transportation. Moreover, the North was vastly stronger than the South on all the inland waters that were not "Secesh" from end to end. The map shows how Northern sea-power could not only divide the South in two but almost enisle the eastern part as well. Holding the Mississippi would effect the division, while holding the Ohio would make the eastern part a peninsula, with the upper end of the isthmus safe in Northern hands between Pittsburgh, the great coal and iron inland port, and Philadelphia, the great seaport, less than three hundred miles away. The same isthmus narrows to less than two hundred miles between Pittsburgh and Harrisburg (on the Susquehanna River); and its whole line is almost equally safe in Northern hands. A little farther south, along the disputed borderlands, it narrows to less than one hundred miles, from Pittsburgh to Cumberland (on the Potomac canal). Even this is not the narrowest part of the isthmus, which is less than seventy miles across from Cumberland to Brownsville (on the Monongahela) and less than fifty from Cumberland to the Ohiopyle Falls (on the Youghiogheny). These last distances are measured between places that are only fit for minor navigation. But even small craft had an enormous advantage over road and rail together when bulky stores were moved. So Northern sea-power could make its controlling influence felt in one continuous line all round the eastern South, except for fifty miles where small craft were concerned and for two hundred miles in the case of larger vessels. These two hundred miles of land were those between the Ohio River port of Wheeling and the Navy Yard at Washington. Nor was this virtual enislement the only advantage to be won.
