What is now called the post-office department was established in 1789 as the “post-office,” and subsequently as the “general post-office,” under the power given to Congress by the Constitution “to establish post-offices and post-roads,” and the exclusive privilege and control of all postal affairs, &c. _ORGANIZATION OF THE POSTAL DEPARTMENT._ Congress shall have power “to establish post-offices and post-roads.” This short, concise, yet _embracing_ sentence sums up the constitutional basis of this department. It is comprehensive enough to all who fully understand the economical and practical workings of our government. Its conciseness is its very history; and that history becomes a mighty _tome_ in the library of nations. The direction and management of the post-office department are assigned by the Constitution to the postmaster-general. That its business may be the more conveniently arranged and prepared for its final action, it is distributed among several bureaus, as follows:—the Appointment-Office, in charge of the First Assistant Postmaster-General; the Contract-Office, in charge of the Second Assistant Postmaster-General; the Finance-Office, in charge of the Third Assistant Postmaster-General; and the Inspection-Office, in charge of the Chief Clerk. The duties of the several departments named above are thus defined:— The postmaster-general “is further directed to superintend the business of the department in all the duties that are or may be assigned to it, and he is required once in three months to render to the Secretary of the Treasury an account of all the receipts and expenditures in the department, to be adjusted and settled as other accounts.” The postmaster-general may establish post-offices and appoint postmasters on the post-roads which are or may be authorized by law, at all such places as to him may appear expedient. He regulates the number of times the mail shall go from place to place, and he is authorized to contract for carrying the mail, and to establish post-roads. _APPOINTMENT-OFFICE._ The Appointment-Office not only has supervision of the appointment and regulation of all postmasters, and the establishment and discontinuance of post-offices, but also the distribution of blanks, wrapping-paper, and twine to all post-offices; the supervision of pay of clerks in post-offices; of allowance for furniture of post-offices; of extra allowances to postmasters under the acts of Congress; of the appointment and pay of special agents, route-agents, local agents, and blank-agents, and of baggage-masters in charge of mails; of the foreign mail transportation and foreign correspondence; together with some other miscellaneous duties. _CONTRACT-OFFICE._
