Could it have been realized at the time, this blow was not wholly unfortunate. There were problems before this first railroad company in America more difficult than the gaining of a right of way to Cumberland. Every feature of its undertaking was in most primitive condition,--road-bed, tracks, rails, sleepers, ties, cars, all, were most simple. The road was an ordinary macadamized pathway; the cars were common stagecoaches, on smaller, heavier wheels. More than all else, the motor force was an intrinsically vital problem. Horses and mules were now being used; a car with a sail was invented, but was, of course, useless in calm weather, or when the wind was not blowing in the right direction. In the meantime the steam locomotive was being perfected, and Peter Cooper's "Tom Thumb" settled the question in 1830, on these tracks of the Baltimore and Ohio Railroad. For a number of years the ultimate practicability of the machine was in question, but when the railroad was in a position to expand westward, in 1836, the locomotive as a motor force was acknowledged on every hand to be a success. In all other departments, likewise, the railroad had been improving. The six years had seen a vast change. With the canal, on the other hand, these had been discouraging years. Though master of the legal situation, money came to it slowly, labor became more costly, unexpected physical difficulties were encountered, floods delayed operations. Again and again aid from Maryland had been invoked successfully; and now, in 1836, it was reported that three millions more was necessary to complete the canal to Cumberland. Maryland now passed her famous "Eight-million-dollar Bill," giving the railroad and canal each three million dollars, with a condition imposed on the Canal Company that the two companies should have an equal right of way up the Potomac to Cumberland. Though the directors of the Canal Company objected bitterly at thus being compelled to resign control of the situation, the needs of the Company were such that acquiescence was imperatively necessary. The Chesapeake and Ohio Canal was completed to Cumberland in 1851, at a cost of over eleven million dollars, the root of Maryland's great State debt.
