19. In your reports to the Postmaster General of the result of an investigation, state whether the enquiry made was personal or by correspondence. State also clearly in the proper order all the facts bearing on the case, and the conclusions which these facts appear to justify.
20. In reporting on cases of a confidential character, in which it is not desirable that the facts should be made public, mark the word "confidential" both on the report and on the cover in which it is transmitted.
21. In all reports in which a previous report is referred to, state in addition to the number and date of the report referred to, its general purport.
22. In all reports Post Offices should be called by their official names, and not by the name by which they may be known in the locality. This rule applies especially to the Maritime Provinces.
23. It is desirable that you should make yourself acquainted, as far as may be practicable, with the general character and financial standing of each Postmaster in your Division who has charge of Money Order or Savings Bank duties; and in any case where you have reason for suspecting the possibility of irregular practices, or a disposition to withhold—even for short periods—Post Office monies, a confidential report should be made to the Postmaster General, in order that a close supervision may be kept by the Superintendent on the returns and remittances received from such Postmasters.
24. In cases of doubt always ask for instructions from the Postmaster General—by letter, if time permits; if not, by telegraph.
25. When absolutely necessary, make use of the telegraph, compressing your message into as few words as are consistent with clearness of meaning. Do not, however, use the telegraph in cases where a letter will answer all the purposes required.
26. Observe in all matters connected with the Department as strict an economy as is consistent with the efficient performance of the Service. Do not in any case recommend additional expenditure unless the circumstances appear fully to justify it.
27. No outlay, whether for alteration in a Mail Service, or for repairs, improvements or fittings, must be incurred without the specific authority first obtained of the Postmaster General.
In every case application for this authority must be accompanied by a full description of the work to be done, and an estimate of the probable expenditure involved.
