=The Difficulties of Early Transportation.=--Means of communication played an important part in the strategy of all those who sought to bring together the seaboard and the frontier. The produce of the West--wheat, corn, bacon, hemp, cattle, and tobacco--was bulky and the cost of overland transportation was prohibitive. In the Eastern market, "a cow and her calf were given for a bushel of salt, while a suit of 'store clothes' cost as much as a farm." In such circumstances, the inhabitants of the Mississippi Valley were forced to ship their produce over a long route by way of New Orleans and to pay high freight rates for everything that was brought across the mountains. Scows of from five to fifty tons were built at the towns along the rivers and piloted down the stream to the Crescent City. In a few cases small ocean-going vessels were built to transport goods to the West Indies or to the Eastern coast towns. Salt, iron, guns, powder, and the absolute essentials which the pioneers had to buy mainly in Eastern markets were carried over narrow wagon trails that were almost impassable in the rainy season. =The National Road.=--To far-sighted men, like Albert Gallatin, "the father of internal improvements," the solution of this problem was the construction of roads and canals. Early in Jefferson's administration, Congress dedicated a part of the proceeds from the sale of lands to building highways from the headwaters of the navigable waters emptying into the Atlantic to the Ohio River and beyond into the Northwest territory. In 1806, after many misgivings, it authorized a great national highway binding the East and the West. The Cumberland Road, as it was called, began in northwestern Maryland, wound through southern Pennsylvania, crossed the narrow neck of Virginia at Wheeling, and then shot almost straight across Ohio, Indiana, and Illinois, into Missouri. By 1817, stagecoaches were running between Washington and Wheeling; by 1833 contractors had carried their work to Columbus, Ohio, and by 1852, to Vandalia, Illinois. Over this ballasted road mail and passenger coaches could go at high speed, and heavy freight wagons proceed in safety at a steady pace. [Illustration: THE CUMBERLAND ROAD]
