But in the case of the public director it was their peculiar and official duty to make the disclosures, and the call upon them for information could not have been disregarded without a flagrant breach of their trust. The directors appointed by the United States can not be regarded in the light of the ordinary directors of a bank appointed by the stockholders and charged with the care of their pecuniary interests in the corporation. They have higher and more important duties. They are public officers. They are placed at the board not merely to represent the stock held by the United States, but to observe the conduct of the corporation and to watch over the public interests. It was foreseen that this great moneyed monopoly might be so managed as to endanger the interests of the country, and it was therefore deemed necessary as a measure of precaution to place at the board watchful sentinels, who should observe its conduct and stand ready to report to the proper officers of the Government every act of the board which might affect injuriously the interests of the people.
The whole frame of the charter, as well as the manner of their appointment, proves this to be their true character. The United States are not represented at the board by these directors merely on account of the stock held by the Government. The right of the United States to appoint directors and the number appointed do not depend upon the amount of the stock, for if every share should be sold and the United States cease to be a stockholder altogether, yet under the charter the right to appoint five directors would still remain. In such a case what would be the character of the directors? They would represent no stock and be chosen by no stockholders. Yet they would have a right to sit at the board, to vote on all questions submitted to it, and to be made acquainted with all the proceedings of the corporation. They would not in such a case be ordinary directors chosen by the stockholders in proportion to their stock, but they would be public officers, appointed to guard the public interest, and their duties must conform to their office. They are not the duties of an ordinary director chosen by a stockholder, but they are the peculiar duties of a public officer who is bound on all occasions to protect to the utmost of his lawful means the public interests, and, where his own authority is not sufficient to prevent injury, to inform those to whom the law has confided the necessary power. Such, then, is the character and such are the duties of the directors appointed by the United States, whether the public be stockholders or not. They are officers of the United States, and not the mere representatives of a stockholder.
