27. When any letter, book-packet, or newspaper is lost, miscarried, or delayed, inquiry should be made as soon as evidence has been obtained that the article in question was really posted. The postmaster of the town should be informed by the complainant of every particular relating to the missing letter, &c. the day and hour of its posting, the office at which and the person by whom this was done. In cases of delay or mis-sending, the covers ought to be produced in order that the office stamps on them may indicate the exact place where the delay has been occasioned. Correspondence on the subject of the complaints will subsequently be carried on between the applicant and the Secretary's department in England, Scotland, or Ireland, as the case may be. 28. When any one has reason to believe that he has paid extra postage on a letter or packet improperly, or has been charged more than the case would warrant, he should apply to his postmaster, who will bring the case before the notice of the Secretary, when, if any mistake has been made, the money will be refunded by order.

Advertisements are occasionally seen, and applications frequently made, for defaced postage-stamps. It is stated, in some cases, that a given number will gain certain individuals admission to different charitable institutions. Whatever may be the purpose for which the old stamps are required, the Post-Office authorities have found, by inquiry, that the ostensible reason here given has uniformly been false. It is sometimes feared that attempts are made to clean and re-issue them, though this can be attended with but partial success. It is much more probable that they are sought to indulge some whim, such as papering boxes or even rooms. 32. With reference to money-orders, the public should be careful--
