9?9 U.S. O?fion of thz Court. imposes the duty upon the Attorney General to cause pro- ceedln? to be instituted s?.inst any corporation whenever of the Revised Laws of 1905 it is also provided that the Attor- ney General shall be e? offw/o attorney for the railroad com- mi?on and it .is made his duty to institute and prosecute all actions which the Commission shall order brought, and shall render the commissioners all counsel and advice neceesary for the proper performance of their duties.

His power by virtue of his office sufficiently connected him with the duty of enforcement to make him a proper party to a su?t of the natur? of the one now before the United States Cirsuit Court.
