“In affixing stamps, to wet slightly the corner of the envelope and the gummed side of the stamp, and then gently to press the stamp till it is firmly fixed. The practice of dipping the stamp in water is objectionable, because, unless the stamp be immediately withdrawn, and care be taken by the use of blotting-paper or some other absorbent to remove any excess of moisture, the gum may be washed off, or the stamp may be rubbed off the letter. By the use of envelopes bearing an _embossed_ stamp (which can be purchased at any post-office), all risk of the stamp being detached may be avoided. “Never to send money or any other article of value through the post, except either by means of a money-order or in a registered letter. Any person who sends money or jewelry in an unregistered letter not only runs a risk of losing his property, but exposes to temptation every one through whose hands his letter passes, and may be the means of ultimately bringing some clerk or letter-carrier to moral ruin. Every letter which contains money or other valuable article, even when registered, ought to be securely sealed.” _FORBIDDEN ARTICLES._ “Postmasters are instructed not to receive any letter, &c. which there is good reason to believe contains any thing likely to injure the contents of the mail-bag or the person of any officer of the post-office. If such a packet be posted without the postmaster’s knowledge, or if at any time before its despatch he should discover any such packet, he is directed not to forward it, but to report the case, with the address of the packet, to the secretary. The following are examples of the articles referred to:— “A glass bottle, or glass in any form; razors, scissors, needles, knives, forks, or other sharp instruments; leeches, game, fish, meat, fruit, or vegetables; bladders or other vessels containing liquids; gunpowder, lucifer matches, or any thing which is explosive or combustible.” _LETTER-CARRIERS, THEIR COMPENSATION, ETC._
