From the 11th November 1704 till Whitsunday 1707, George Main, jeweller in Edinburgh, accounts in Exchequer for the duties of the Post Office within Scotland, leased to him by the Lords of the Treasury and Exchequer in Scotland, during the three years ending at the latter date, for the yearly rent of 21,500 merks Scots, or £1194, 8s. 10d. sterling, subject to a deduction for the conveyance of public expresses, &c., and also a sum not exceeding £60 per annum for keeping a packet boat for carrying the Mails between Portpatrick and Ireland. It appears that he paid the following yearly salaries, viz.-- Postmaster at Haddington £50 sterling. Postmaster in Canongate 35 " Postmaster at Cockburnspath 50 " James Weems, Clerk to the Post Office, 25 " Postmaster of Portpatrick for the Charge } of a Packet Boat } 60 " The expense of the Secretary's Packet and Expresses from the Post Office to London, from 11th November 1704 to 1st May 1707, amounted to £1994, 9s. sterling. The expense for Expresses for public affairs of the Government, sent and received betwixt London and Berwick, from 18th January 1707 to 1st May 1707, paid to the London Post Office, amounted to £476, 2s. 6d. Between 14th March and 6th October 1705, there were 25 "flying packets" (or special despatches) outgoing, and from 21st January to 3rd October 1705, the like number of flying packets sent by them. The cost of these paid to the Postmaster of Haddington and Cockburnspath was £23, 15s. sterling. The same Postmasters received £40, 14s. 6d. sterling for flying packets sent by them for the stages between Edinburgh and Berwick, from 14th April 1706 to 1st May 1707. A sum of £13, 5s. sterling was also paid for inquiries as to a robbery of the packet at or near Dunglass Miln.[20] From this period downwards, the data are of a more minute description, giving the condition of the Post Office more in detail, and affording the means of estimating its progress by the extent of its establishment. In 1708, the business of the General Post Office at Edinburgh was discharged by seven persons, viz.--George Main, manager for Scotland, who held his commission from the Postmaster-General of Great Britain, salary £200 per annum; his accountant, £50 per annum; a clerk, £50; the clerk's assistant, £25; three letter-carriers or runners, each 5s. per week.[21] In 1710, the Act of William, 1695, was repealed by an Act of Anne, and the Post Office of Scotland was united with that of England, Ireland, and America under one Postmaster-General. It was ordained "that a Chief Letter Office be kept at Edinburgh, and the Packet Boats between Donaghadee and Portpatrick are still to be maintained." This Act also regulates the rates of Postage.[22]
