distinct classes, the legislative, the judicial, and the executive. The
Constitution provides as to the methods for the exercise of the first
two, but none for the third. The only reference in the constitution to
executive departments is in Art. II, Sec. 2, where the President is
given the power to require the opinion in writing of the principal
officer in each executive department upon any subject relating to the
duties of his office. The departments have in each case been created by
an act of Congress and from time to time as convenience has demanded.

The duties of the executive are to enforce and apply the laws of the
nation after they are made by the legislature and interpreted by the
courts. This is the real business of government, by which the laws are
put into effect, and the work of government is actually carried on. In
the United States Government this power is placed in the hands of a body
of men distinct from the legislative and judicial officers. At the head
is the President, and hence his title of "Chief Executive." It is
evident that he must divide up the vast amount of work to be done, and
delegate it to others. Congress directs how this shall be done. For this
purpose Congress has created nine executive departments (1)State,
(2)Treasury, (3)War, (4)Navy, (5)Interior, (6)Post Office, (7)Justice,
(8)Agriculture, (9)Labor.

These departments have been created as required by the growth of
government duties. Three departments, the State, Treasury and War, were
created by the first Congress, in 1789. By the same Congress was created
the office of Attorney-General of the United States, who, together with
the Secretaries of the three departments, constituted President
Washington's first cabinet. The Navy Department was added in 1798. Prior
to that date, naval affairs had been managed by the War Department. A
Post Office for the colonies was established by the Postal Act of Queen
