In 1643 the postal revenue amounted to some £5,000 a year only. By 1677 the Department's profits were farmed at £43,000 a year, and the officials consisted of one Postmaster-General and seventy-five employees. A writer of the day tells us that “the number of letter missives is now prodigiously great.” In 1658 John Hill, a Yorkshire attorney, did good work, and tried to accomplish more. He already supplied post horses between York and London, undertook the conveyance, at cheap rates, of parcels and letters, and established agencies about the country for the furtherance of a scheme to greatly reduce the postal charges throughout the kingdom; his proposal being a penny rate for England and Wales, a twopenny rate for Scotland, and a fourpenny rate for Ireland. But the Government declined to consider the merits of the plan. When Dockwra—who gave practical shape to the scheme which Murray had assigned to him—established his reform of a penny post, London had no other post office than the general one in Lombard Street,[53] and there was no such thing as a delivery of letters between one part of London and another. Thus, if any Londoner wished to write to any other Londoner, he was obliged to employ a messenger to convey his missive to its destination; and as the houses then had no numbers, but were distinguished only by signs, the amateur letter-carrier must have been often puzzled at which door to knock. Dockwra soon put his great scheme into working order. He divided city and suburbs into districts—in that respect forestalling a feature of Rowland Hill's plan—seven in number, each with a sorting office; and in one day opened over four hundred receiving offices. In the city letters were delivered for 1d., in the suburbs for 2d. It must have been quite as epoch-making a reform to the Londoners of the seventeenth century, as was the far wider-reaching, completer scheme established a hundred and sixty years later to the entire nation. For Dockwra's, though for its time a wonderful advance, was but a local institution, the area served being “from Hackney in the north to Lambeth in the south, and from Blackwall in the east to Westminster in the west.”[54] He also introduced a parcel post. The local penny posts—for they were afterwards extended to many other towns—have given some people the erroneous impression that Rowland Hill's plan of penny postage was simply an elaboration and a widening of Dockwra's older system. Things called by a similar name are not necessarily identical. Indeed, as we have seen, the word “postage” had formerly quite a different meaning from that it now has; and, although Dockwra's “penny post” and Rowland Hill's “penny postage” related equally to postage in its modern interpretation of the word, that the system established in 1840 materially differed from preceding systems will be shown in the succeeding chapter.[55]
