The North-German Union was established in 1867, and the postal arrangements for the whole territory of the Union were unified. Up to this time ten independent postal administrations had existed in this territory,[247] and the rates of these administrations differed in various particulars. The Prussian rates were applied temporarily to all postal traffic passing between the old and new Prussian territories, and the rates of the Union service were applied to traffic passing between the territories forming the North-German Union. The continuance of these conditions was not consistent with a unified administration of the postal affairs of the whole North-German Union, and a reform of the rates became necessary. Germany was in 1867 almost the only one of the great States of the world which still maintained a scale of rates of postage for letters graduated according to distance. Prussia had already repeatedly endeavoured to introduce the principle of uniformity of rate irrespective of distance which had been adopted by all others, or at least to secure further simplification; but advance in this direction had always been hindered by financial considerations.[248] The political developments now opened the way for a thorough reorganization of the rates, and this was achieved by the law of the 4th November 1867. This law, which took effect from the 1st January 1868, established uniform rates for letters, irrespective of distance, of the following amounts--1 sgr. (= 10 pf.) for letters not exceeding half an ounce in weight, and 2 sgr. for all letters of greater weight. After the refounding of the German Empire in 1870, there was fresh legislation in regard to the Post Office.[249] Among other changes, the limit of weight for the single letter was fixed at 15 grammes, and the limit of maximum weight at half a pound. This law also abolished the charge for rural delivery, a long-desired reform which had been frequently urged upon the Reichstag. In order to assist further the interests of residents in the country, it was arranged that on payment of a monthly fee of 5 sgr. letters might be handed to and delivered by the post messenger, in a closed pouch, at places on his route.
