no necessity on this head for any accounts between the several Administrations of the Union.
Neither the senders nor the addressees of letters and other postal articles are called upon to pay, either in the country of origin or in that of destination, any postage or any postal fee other than those contemplated by the Articles above-mentioned.
Article 10
No additional charge is levied for the reforwarding of postal matter within the interior of the Union.
Article 11
It is forbidden to the public to send by mail:
- 1st. Letters or packets containing gold or silver substances, pieces of money, jewelry, or precious articles;
- 2d. Any packets whatever containing articles liable to customs duty.
In case a packet falling under one of these prohibitions is delivered by one Administration of the Union to another Administration of the Union, the latter proceeds according to the manner and forms prescribed by its legislation or by its interior regulations.
There is, moreover, reserved to the Government of every country of the Union, the right to refuse to convey over its territory, or to deliver, as well articles liable to the reduced rate, in regard to which the laws, ordinances, or decrees which regulate the conditions of their publication or of their circulation in that country have not been complied with, as correspondence of every kind which evidently bears inscriptions forbidden by the legal enactments or regulations in force in the same country.
Article 12
The offices of the Union which have relations with countries beyond the Union admit all the other offices to take advantage of such relations for the exchange of correspondence with the said countries.
The correspondence exchanged in open mails between a country of the Union and a country foreign to the Union, through the intermediary of another country of the Union, is treated, as regards the conveyance beyond the limits of the Union, in conformity to the conventions, arrangements, or special provisions governing the postal relations between the latter country and the country foreign to the Union.
The rates chargeable on the correspondence in question consist of two distinct elements, viz:
- 1st. The Union rate fixed by Articles 5, 6, and 7 of the present Convention.
- 2d. A rate for the conveyance beyond the limits of the Union.
