United States, and two cents British; each country to collect its own postage, whether the paper is sent from or received in the United States. [British newspapers usually come British postage paid by a penny stamp, equal to two cents.] They must be sent in narrow bands, open at the ends. Letters for the continent of Europe, to pass through Great Britain, in the open mail, must be prepaid 21 cents when the Atlantic conveyance is by United States packets, and 5 cents when by British packets, except from California or Oregon, when the sum to be prepaid is, in the former instance, 26 cents, and in the latter, 10 cents. Thus, in the one case, the Atlantic sea postage is to be collected at the mailing office, in the United States; and in the other, left to be collected, together with the British transit and other foreign postage, at the office of delivery. Between Great Britain and Oregon and California, the single rate of letter postage is 29 cents.

Periodical works and pamphlets may be sent from the United States to the United Kingdom, and vice versa, at two cents of United States postage each, if they do not exceed two ounces in weight, and at 4 cents per ounce, or fraction of an ounce, when they exceed that weight; to be collected in all cases in the United States; and the same will be subject to an additional like charge in the United Kingdom. When sent to France, Algeria, or cities in Turkey, Syria, and Egypt, in which France has post-offices, via England, or to other foreign countries, without passing through the United Kingdom, they will be chargeable with 1 cent an ounce, or fraction of an ounce, United States postage-prepayment required.

Single rate of letter postage to or from Bremen, by the Bremen line, 10 cents-prepayment optional. Newspapers, each 3 cents, being the United States and German postage-prepayment required. Letters and newspapers to other parts of the Continent may also go by this line, subject to various rates; for which see Foreign Postage Table.

Single rate of letter postage by the Prussian closed mail to Prussia, Austria, and all the other German States, 30 cents, being the full postage-prepayment optional. Newspapers, 6 cents each, being also the full postage-prepayment required. This mail is sent by every steamer, being landed at Liverpool by the Collins, and at Southampton by the Bremen lines. The system of registration of valuable letters adopted in the United States has been extended to the correspondence with Great Britain, Prussia, Bremen, and Canada. Letters addressed to either of those countries will be registered, on the application of the person posting the same, in the same manner and on the same terms as those deliverable in the United States, provided that the full postage chargeable to destination, together with a registration fee of five cents on each letter, is prepaid at the mailing office. Such letters should be mailed and forwarded to the respective United States exchange offices in the same manner as domestic registered letters are mailed. N. B.-All letters to and from foreign countries (the British North American Provinces excepted) are to be charged with single rate of postage, if not exceeding the weight of half an ounce; double rate, if exceeding half an ounce but not exceeding an ounce; quadruple rate, if exceeding an ounce but not exceeding two ounces; and so on, charging two rates for every ounce or fractional part of an ounce over the first ounce. Letters in the mail to France are to be charged with single rate of postage, if not exceeding the weight of one quarter ounce; double rate, if exceeding a quarter but not exceeding half an ounce; and so on, an additional rate being charged for each quarter ounce or fractional part of a quarter ounce. Letters addressed to the British North American Provinces are rated in the same manner as domestic letters, one rate being charged for each half ounce, or fractional part of half an ounce. Postmasters should be careful. where the postage is prepaid, to collect the proper amount. They should be particular

to notice the route indicated on the envelopes of letters, and to collect postage accordingly. Letters mailed at some offices, marked "via England," or" via Prussian Closed Mail," for a German State, are frequently taken upon the prepayment of Bremen rates, and those marked "via Bremen" at Prussian closed mail rates, etc. Refer in all cases to the Postage Tables.

If letters for foreign countries, marked “Paid,” are dropped into the postoffice without being paid, the postmaster will erase the word "Paid," and write on the back of the letter the words "Not paid," with his name and title of postmaster.

The mails for the Pacific leave New York on the 5th and 20th, Charleston and Savannah on the 4th and 19th, and New Orleans on the 5th and 20th of each month.

Mails for Mexico will be dispatched semi-monthly by steamship between New Orleans and Vera Cruz. United States letter postage, 10 cents under 2,500 and 20 cents over 2,500 miles from the mailing office; to be prepaid when sent from and collected when received in the United States. Newspapers, 2 cents each, to be collected in the United States, as above.

Single rate of letter postage to Havana, Aspinwall, Panama, and the British West Indies, 10 cents under 2,500 and 20 cents over 2,500 miles; newspapers, 2 cents; and to West Indies (not British), Carthagena, Honduras, and St. Juan (Nicaragua), 34 cents under 2,500 and 44 cents over 2,500 miles; newspapers, 6 cents each--prepayment required.
