instead of turning it over to the State treasury. How is it possible, then, to base rates on cost of service and still leave the incentive to economy, frugality, and efficiency which exists, when the corporation is permitted to make all the profits it can?"
To discover a means of overcoming this difficulty, let us see how it is overcome under competition. A man invents a new machine, for instance, which effects a saving in the cost of some manufacturing process of 50 per cent. One manufacturer adopts it because it greatly increases his profits, and one by one his competitors follow suit. The competition between them cuts the prices lower and lower, till finally the consumers of the goods get all the benefit from the saving effected by the new machine, and the manufacturers' profits are no greater than they were originally. But the important point to be noted is this, that the benefit to the manufacturer continued long enough to repay him for introducing the machine. So in our attempts to base railway rates upon cost of service, we must permit the profit from the introduction of economies, the use of improved appliances, etc., to be gathered by the railway company long enough to induce it to work toward that end.
All we need to do to effect this end is to somewhat delay the change in rates to correspond to change in cost of service. As already stated, it is most necessary that rates should be stable, and it is proposed to make any change, either advance or reduction, only through the action of a Government Commission. Now, suppose that some such clause as this forms a part of our railway law: "upon the petition of any railway corporation, or of not less than twenty-five patrons of any single 'railway district,' it shall be the duty of the Railway Commission to investigate regarding a readjustment of rates to correspond more closely to the cost of service. If it shall be found that in the given 'railway district' the net receipts over the operating expenses and fixed charges have been for one year not less than 9 per cent. on the capital of the operating company invested in the given railway district; and that for two successive years they
