It is inevitable, of course, that engineers will differ in their opinions as to some details of methods of making an inventory of the property of a railroad or other public service corporation, and also as to exactly what unit prices should be applied, but in general it is safe to say that any engineer of proper experience and training can make a satisfactory appraisal of the value of the physical property of a railroad, and that if two or more such competent fair-minded engineers, unhampered by any consideration of the purpose for which it is to be made, should make such an appraisal, the variation in the result would be so small as to be negligible. The speaker, however, does not entirely agree with the author, that the purpose for which the appraisal is to be used should be entirely ignored by those who are making it. There can be little doubt as to the propriety of using a properly made physical valuation as a basis for taxation, or as information for the owners, although there may be some as to the methods whereby the so-called intangible values are to be determined in these cases, or even whether they should be considered at all. The greatest difference of opinion arises when an attempt is made to regulate the issue of stocks and bonds, or to fix the rates which should be charged for transportation, on the basis of a physical valuation. Arguments for and against rate regulation revolve in a circle, and, apparently, there is no starting point which will satisfy every one. The Courts have ruled that the railroads are entitled to such rates as will enable them to earn a fair return on the value of their property; the railroads claim that the only way to determine this value is on the basis of the earning capacity; that is, one side claims that the rates must be based on the value and the other that the value should be based on the rates. It is evident, however, by this time, that the railroads must submit to regulation, therefore a way must be found to break into the circle, and it would seem to be incumbent on them to direct their energies along lines which will tend to make such regulation fair and just rather than to oppose it entirely. There is little claim that unduly large dividends are paid, but there is a feeling in the mind of the public that the railroads are over-capitalized. Is it not possible, therefore, to break into the circle at this point, and decide, by means of a proper valuation, as to the fairness or otherwise of the capitalization? The objection to this, on the part of the railroads, is that the value of the purely physical elements is by no means the whole value of their property, but that something should be added for the so-called intangible values.
