"The magnitude of the business of this road, its numerous and important connections, and. the large number of employés engaged in operating it, have led many, whose opinions are entitled to respect, to the conclusion, that a proper regard to details, which enter so largely into the elements of success in the management of all railroads, cannot possibly be attained by any plan that contemplates its organization as a whole ; and in proof of this position, the experience of shorter roads is referred to, the business operations of which have been conducted much more economically. Theoretically, other things being equal, a long road should be operated for a less cost per mile than a short one. This position is so clearly evident and so generally admitted, that its truth may be assumed without offering any arguments in support of it ; and, notwithstanding the reverse, so far as practical results are considered, has generally been the case, we must look to other causes than the mere difference in length of roads for a solution of the difficulty."
