When a regular service of posts was again established in France, it was provided, not by the State, but by the University of Paris, which in the twelfth and thirteenth centuries increased in importance and renown, and attracted large numbers of students from all parts of France, and from foreign countries. In order to provide a means of communication between the students and their homes, the University obtained from the King authority to employ for the purpose messengers, to whom were accorded certain special privileges. Thus, in 1296, the messengers of the University were exempted from payment of tolls, or of fees for entry into towns. At first they travelled on foot, but at a later date on horseback or by carriage. The system developed regularity and rapidity, and in the fourteenth and fifteenth centuries was employed, although without authority, by the public generally.[179] This service continued until 1720, when the privileges of the University were suppressed, monetary compensation (120,000 fr.) being paid from the revenue of the posts.[180] An ordinary postal service was re-established by Louis XI in 1464.[181] Relay stations were set up on the main routes, four leagues apart. At each station four or five horses were provided by the postmasters, who were required to convey the royal despatches without special remuneration. For conducting the royal couriers from stage to stage, however, payment was made at the rate of 10 sous for each stage for every horse. In 1527 the postmasters were given the exclusive right of furnishing horses for the use of couriers. In order to provide accommodation for travellers, a system of relays was established in 1597, in addition to the ordinary posts.[182] The stages were fixed at distances varying from twelve to fifteen leagues, and the charge for a horse was 20 sous for each stage. This system was amalgamated with the posts in 1602, and the functions for which the relays had been established were exercised by the posts until after the Revolution. They were definitely abandoned to private enterprise in 1797. The transmission of ordinary letters for private individuals was not at first contemplated,[183] but it became common for the royal messengers to carry letters for the public. The conveyance of private letters was first definitely provided for by the State in 1576. In that year a special system of messengers was established, whose function was to convey legal documents between the Parliament and the inferior courts, and was limited to the period during which Parliament was sitting. These messengers were required to carry letters for private individuals at the following rates:-- For a single letter 10 deniers For a packet of three or four letters 15 " For packets of letters weighing an ounce or more 20 " irrespective of distance.[184]
