The Saint Louis directory for the years 1854-5 :

must be prepaid 21 cents, when the Atlantic conveyance
is by U. S. packets, and 5 cents when by British packets,
except from California or Oregon, when the sura to be
Pre-paid 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 to-
gether with the British transit and other foreign post-
age, at the office of delivery. Between Great Britain
and Oregon and California, the single rate of letter post-
age is 29 cents.

Periodical works and pamphlets may be sent from the
United States to the United Kingdom, and vice versa,
at 2 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 foreign countries.
without passing through the United Kingdom, they will
be chargeable with one cent an ounce or fraction of an
ounce, United States postage, pre-payment required.

Single rate of letter postage to or f mm Bremen. by
the Bremen line, 10 cents—pre-payment optional.—
Newspapers, each 2 cents United States postage, pre-
payment 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 to or from France, by the
Havre line. 20 cents, to be pre-paid on letters sent, and
collected on letters received. Newspapers, 2 cents each,
to be collected in the United States, whether the paper
is sent or received.

Single rate of letter postage by the Prussian closed
mail semi-weekly, to Prussia, Austria, and all the other
German States—30 cents being the full postage—pre-
payment optional. Newspapers. 6 cents each, being also
the full postage—pre-payment required.

☞N. B.—All Letters to and from Foreign Countries (the British North American Provinces ex-
cepted) are to be charged with single rate of postage, if
not exceeding the weight of half an ounce; doubl 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.
As this rule differs from that followed in respect to do-
mestic letters, great care is requisite to prevent mistakes.
Postmasters should bo careful, also, where the postage
is prepaid, to collect the proper amount. They should
be particular to notice the route indicated on the en-
velops of letters and to collect postage accordingly.
Letters mailed at some offiees, marked “via England”
or “via Prussian closed Mail,” for the German States.
are frequently taken upon the pre-payment of Bremen
rates, and those marked “via Bremen,” at Prussian
closed mail rates, &c. Refer in all cases to the Postage
Tables.
