The principle on which the District Post was based was the liability of landholders to maintain communications for Government purposes between the executive head of a district and his subordinates in outlying places--a responsibility which in many instances they were glad to discharge by a money payment to the magistrate who undertook the organization of the requisite agency. The laws under which it was administered were framed with the object of levying a small cess in each district. This was used, at the discretion of the magistrate, for the payment of dak-runners and other persons who conveyed correspondence between police stations and district officials. This local post undoubtedly existed from ancient times, and its maintenance was a liability to which the landholders had been subject from a period long before the advent of British rule. The District Post in India, which was an important, though not very efficient, auxiliary to the Imperial Post, thus owed its origin to the need for maintaining the means of official communication between the head-quarters of each district and the revenue and police stations in the interior, where the general wants of the locality were not such as to call for the provision of Imperial post offices. It consisted of lines of communication connecting such stations, and was maintained primarily for the conveyance of official correspondence in accordance with the requirements of each district, but subsequently it was also made available for private correspondence. In some parts of the country the cost of the District Post lines was met by local cesses specially levied for the purpose, and in other places it was met from Imperial or provincial grants as a charge on the general revenues of the country.
