He has the entire direction and management of the Department, and the appointment of all local postmasters (in law considered as his deputies), whose salary is less than $1,000 per annum. All others are appointed by the President and Senate. That its business may be more conveniently arranged and prepared for his final action, it is distributed among several bureaus, or minor departments as follows: THE APPOINTMENT OFFICE. Includes the divisions of appointments; bonds given by postmasters, agents, and clerks; salaries and allowances, where they are not provided for by law; free delivery in cities; and the agency of blanks used in the extensive business and reports of the department. This office is in charge of the First Assistant Post Master General. THE CONTRACT OFFICE. This includes the divisions of contracts for carrying the mails, by persons or companies; the inspection of the entire process of carrying the mails, to secure their safe, regular, and prompt delivery; mail equipment, or the supply of all the material and conveniences for transportation of the mail, furnished by the department; special agents, and mail depredations, which has the care of all violations of law and the conduct and accounts of all agents employed for the suppression and prevention of abuses; and the Topographical, which has charge of maps and diagrams of mail routes, and geographical information, required for the various branches of the service. It is in charge of the Second Assistant Post Master General. THE FINANCE OFFICE. This is separated into the divisions of Finance, which has charge of the entire cash receipts, transfers, and disbursements of the department; of postage stamps and stamped envelopes, newspaper wrappers, and postal cards; registered letters and seals; and the examination of Dead Letters and their return to the writers. Dead letters are those not taken out of the office to which they were sent. After being advertised three weeks in some newspaper near the office where they were sent, they are returned to the General Post Office, where they are examined; and if they contain money or valuable papers they are returned to the writers and an account of them kept at the General Post Office. The sums, so lost and taken care of, amount annually to tens of thousands of dollars. The Third Assistant Post Master General has charge of it. THE MONEY ORDER OFFICE. The Money Orders System furnishes very convenient and safe banking facilities for the transfer of money in small sums. It diminishes as much as possible the exposure of money to loss by theft or otherwise, through the plan of depositing in one office, and sending a certificate of such deposit which is good for the money at another office. Immense sums are so exchanged and business facilitated without any actual passage of the money from one point to the other. When it is necessary to preserve the balances it is done by, and at the risk of, the department.
