The consolidations need to be carried out with due regard to public interest and to the rights and established life of various communities in our country. It does not seem to me necessary that we endeavor to anticipate any final plan or adhere to an artificial and unchangeable project which shall stipulate a fixed number of systems, but rather we ought to approach the problem with such a latitude of action that it can be worked out step by step in accordance with a comprehensive consideration of public interest. Whether the number of ultimate systems shall be more or less seems to me can only be determined by time and actual experience in the development of such consolidations.
