But here also we have a cotemporaneous construction of the act which shows that it was not understood as in any way changing the relations between the President and Secretary of the Treasury, or as placing the latter out of Executive control even in relation to the deposits of the public money. Nor on that point are we left to any equivocal testimony. The documents of the Treasury Department show that the Secretary of the Treasury did apply to the President and obtained his approbation and sanction to the original transfer of the public deposits to the present Bank of the United States, and did carry the measure into effect in obedience to his decision. They also show that transfers of the public deposits from the branches of the Bank of the United States to State banks at Chillicothe, Cincinnati, and Louisville, in 1819, were made with the approbation of the President and by his authority. They show that upon all important questions appertaining to his Department, whether they related to the public deposits or other matters, it was the constant practice of the Secretary of the Treasury to obtain for his acts the approval and sanction of the President. These acts and the principles on which they were founded were known to all the departments of the Government, to Congress and the country, and until very recently appear never to have been called in question. Thus was it settled by the Constitution, the laws, and the whole practice of the Government that the entire executive power is vested in the President of the United States; that as incident to that power the right of appointing and removing those officers who are to aid him in the execution of the laws, with such restrictions only as the Constitution prescribes, is vested in the President; that the Secretary of the Treasury is one of those officers; that the custody of the public property and money is an Executive function which, in relation to the money, has always been exercised through the Secretary of the Treasury and his subordinates; that in the performance of these duties he is subject to the supervision and control of the President, and in all important measures having relation to them consults the Chief Magistrate and obtains his approval and sanction; that the law establishing the bank did not, as it could not, change the relation between the President and the Secretary--did not release the former from his obligation to see the law faithfully executed nor the latter from the President's supervision and control; that afterwards and before the Secretary did in fact consult and obtain the sanction of the President to transfers and removals of the public deposits, and that all departments of the Government, and the nation itself, approved or acquiesced in these acts and principles as in strict conformity with our Constitution and laws.
