This was a system for the conveyance of official despatches only.[2] No public provision was made for the conveyance of letters for private individuals. Such letters were conveyed by servants, by special messengers, or by the common carriers,[3] and there is evidence of the existence of a considerable private correspondence in the frequent issue of writs during the fourteenth and fifteenth centuries ordering supervision of the traffic in private letters, the uninterrupted transmission of which was a source of much anxiety to the Crown from fear of the fomenting of sinister and treasonable plots against itself.[4] The establishment of the _nuncii_ or _cursores_ developed into a regular system. On certain lines of road relay stages were set up, at which the messengers might without delay obtain a change of horses, a system first set up by Edward IV in 1482, during the war with Scotland.[5] Such relay messengers were called "posts," a word borrowed from the French.[6] The term was also applied to the line of route, and the expression "post," or "line of posts," was used to denote a route along which, at certain stages, post-horses were kept in readiness for the use of the King's messengers. Travelling in this way the messengers were able to cover a hundred miles a day. The establishment of lines of regular posts became a feature of the administrative system, and a special officer of the royal household was appointed to control them. The first recorded Master of the Posts was Brian Tuke, who held the office in 1512. The posts, like the establishment of special messengers, were maintained solely at the cost of the King. The master received a salary from the King (which in a patent issued in 1545 is given as £66 13s. 4d. a year), and also the amount of his expenses incurred in providing for the carrying of letters. The regular postmasters received a daily wage from the King. On lines along which no regular post had been established, but along which it might on occasion be necessary to send special messengers, the townships were obliged to furnish horses for the service of the messengers. Remarks in contemporary papers suggest that no payment was made in such cases, but that horses were supplied gratis for the King's service.[7] There is no record of the early days of Tuke's tenure of the office of Master of the Posts; but in 1533 Thomas Cromwell complained to Tuke concerning the condition of the posts, and the great default in the conveyance of letters.[8]
