The second disadvantage of too great elasticity in freight rates is that it may, at times, promote rather than lessen that state of economic unrest inevitable in all business, especially in a new country. Under a continual disturbance of rates, the merchant is unable with security to enter into long-time contracts. Rates are sometimes changed, not to suit the shipper but to serve the railway's interests. Sometimes traffic may be diverted from its natural channels. The spirit of initiative and self-reliance on the part of shippers may be undermined. Persistent titillation of competition may be pleasant for a time, but its final results may be injurious. Constant appeal to the traffic manager of his road for aid and comfort may quite naturally divert the shipper's attention from an aggressive commercial policy which would render him independent of minor changes in freight rates. The more responsibility the traffic manager assumes, the more may be put upon him. And it must always be remembered that each move by one road to protect a client, will probably be checkmated by the tactics of rival lines. Economic peace, not warfare, should be encouraged by the services of common carriers. One of the positive advantages of governmental regulation of railway rates is that it contributes to stability. That this view is shared by experienced railway men, appears from the following testimony of President Mellen of the New Haven road.[132] "I think that great trouble comes to the business of this country through the fact of these little breaks in rates. During November two new railways were opened into the city of Denver. They sought to make themselves popular by lowering rates, and rates went down very low. They went down legally, but they went down very low. Just before the rates went down the merchants of the city had stocked Denver with goods and the lowering of the rates demoralized their prices; they lost a large amount of money, and dissatisfaction was caused from Chicago to Denver. Lowering of rates demoralized business generally. I think if those roads had known that the rates which they made had to remain in force thirty days they would have hesitated before they lowered them. I would increase the time required before rates could be reduced."
