[609] "N'est-ce pas pr['e]cis['e]ment l'unit['e] de tarif qui
caract['e]rise le colis postal? Elle est tr[e']s appreci['e]e du
commerce dont elle facilite les op['e]rations. Si l'on entre dans la
voie de la taxation au poids, comme pour les articles de messagerie, ce
sera un recul."--M. Mazoyer, _Documents du Congr[e']s postal de Rome_,

[610] The analysis relates to the British inland service in 1913-14.

[611] The number of packets sent at the blind post rate is very small
comparatively (some 300,000 a year), and those packets are therefore not
considered separately.

[612] In general, for any supplemental service an additional fee is
charged, the only exceptions being that, in the case of a packet sent at
the letter rate of postage, if the person to whom it is addressed cannot
be traced, the packet is returned to the sender without charge; and that
under certain conditions the address written on any packet (but not the
name of the person to whom it is addressed) may be amended, and the
packet sent forward, without payment of additional postage. Parcels are
forwarded to a second address in this way free of charge only when the
first address and the substituted address are within the delivery of the
same post office, or are within the same "town delivery area." In
certain circumstances the Post Office itself undertakes to amend the
address and forward packets in this way free of charge--that is to say,
to "redirect." These are, however, minor services, and apply only to a
small fraction of the total number of packets posted. For example, the
actual proportion redirected is as follows:--

Per cent. of
Total Number posted.
Letters 2.2
Postcards 4.0
Halfpenny packets 2.0
Newspapers 1.7

The service of free redirection applies to all classes of packets; but
for the return to the sender in case of non-delivery of postcards,
halfpenny packet, or newspapers, an additional rate of postage is
charged, and the packets are only so returned when they bear on the
outside a written or printed request for return in case of non-delivery.
This inquiry relates only to the cost of the simple transmission and
delivery of the packet, and consideration of all other services, such as
registration or express de
