Hardly a trunk line road exists to-day that has not grown up from a small beginning, changed its line, reduced its grades, added safety devices, changed the type of its bridges and buildings, increased the weight of its rails, put in service much heavier equipment, in fact, completely changed everything, except, perhaps, the original right of way.

The task of securing from old accounting department records an accurate statement of cost is—and the writer says it with the confidence born of experience—an impossibility. It is a job of such magnitude as to be practically prohibitive. The different systems of accounting, the different policies of the management, as to charging betterments to capital or operating expense, to say nothing of the countless errors that creep into the distribution of accounts, place such an undertaking among the labors of a modern Hercules, and, to one who has been engaged even in the task of trying to ascertain what one year's accounting on a large road may do in concealing betterments under the guise of operating expense, it would appear that a result that could be sworn to as correct was impossible of attainment along the lines suggested in this report.

The report of this valuation was published in the form of a pamphlet which is now practically out of print, as all extra copies were long ago exhausted.
