I am well aware of the difficulties of the legislation that I am suggesting, and of the need of temperate and cautious action in securing it. I should emphatically protest against improperly radical or hasty action. The first thing to do is to deal with the great corporations engaged in the business of interstate transportation. As I said in my message of December 6 last, the immediate and most pressing need, so far as legislation is concerned, is the enactment into law of some scheme to secure to the agents of the Government such supervision and regulation of the rates charged by the railroads of the country engaged in interstate traffic as shall summarily and effectively prevent the imposition of unjust or unreasonable rates. It must include putting a complete stop to rebates in every shape and form. This power to regulate rates, like all similar powers over the business world, should be exercised with moderation, caution, and self-restraint; but it should exist, so that it can be effectively exercised when the need arises.
