and for each 10 miles further, 1 silver groschen more.

A map of distances was prepared, and every post office was furnished
with a table compiled from this map, showing the distances between that
office and all other post offices in Prussia, together with the
corresponding rates of postage.[235] Formerly, direct rates of postage
existed only between a limited number of post offices, and letters for
any other places were charged an additional rate (_Binnenporto_) in
respect of the distance not covered by the ordinary rate. This charge
was now abolished. Each post office could calculate the rate to any
other post office by means of its table of rates. There was, however, an
additional charge (_Landporto_) in the case of places at which there was
no post office, but which were situated on the post routes. It was
arranged that letters might be despatched to or from such places so long
as the post-messenger was not thereby delayed on his journey, and for
the forwarding of any such letters to or from the nearest post office
the lowest rate of postage was charged, reckoned as from the nearest
post office. Letters up to 1 ounce in weight were sent by riding post.
Letters exceeding 1 ounce in weight were sent by parcel post
(_Fahrpost_), and were charged the corresponding rate, unless the sender
expressly requested transmission by riding post.

For the longer distances the rates were higher than previously. The rate
for the greatest distance within the Prussian postal territory, which
under the old rates was 18 silver groschen for a single letter--that is,
for a letter up to 3/8 ounce in weight--was now 19 silver groschen. The
reduction was greatest for letters going only short distances. The rate
for the shortest distances was reduced from 1-1/2 silver groschen to 1
silver groschen. But the higher rates applied to letters passing between
the great centres, and these formed the greater part of the whole
number. In addition, the progression of the scale of weights was made
very rapid. From the earliest days of the Post Office in Prussia the
progression of weight had been by the half-ounce, and this had not been
changed even in 1766. The scale was now made--

From 3/8 oz. to 1/2 oz. 1-1/2 times the rate
