The courts will determine the limits within which the Federal authority can exercise it, and there will still remain ample work within each State for the railway commission of that State; and the National Interstate Commerce Commission will work in harmony with the several State commissions, each within its own province, to achieve the desired end. Moreover, in my judgment there should be additional legislation looking to the proper control of the great business concerns engaged in interstate business, this control to be exercised for their own benefit and prosperity no less than for the protection of investors and of the general public. As I have repeatedly said in Messages to the Congress and elsewhere, experience has definitely shown not merely the unwisdom but the futility of endeavoring to put a stop to all business combinations. Modern industrial conditions are such that combination is not only necessary but inevitable.
