Occasionally several expresses would be required at one time. In 1696, on the discovery of Barclay's plot to assassinate the King, orders were given to close the ports; and these orders the postmasters-general sent, as they were instructed to do, by express. Some twenty years afterwards similar orders were given, and an account is still extant shewing how on the later, and probably the earlier, occasion they were carried into effect. The English ports were sixty-two in number; and to only ten of these were expresses sent direct from Lombard Street, the others being either taken by the way or reached by branch expresses furnished by the towns through which the expresses from London passed. Altogether the distance traversed was 2526 miles, the number of stages 202, and the sum which the Post Office received for the service from the Commissioners of Customs £36:12:6. From expresses it seems almost natural to pass to flying packets, although between the two there is, so far as we are aware, no necessary connection. What was a flying packet? The term "flying," at the end of the seventeenth and beginning of the eighteenth centuries, was, no doubt, used in the sense of running. For this season, writes Lord Compton's private tutor to Lady Northampton, under date September 1734, "the coach has done flying." In like manner "flying post," a term as old as the Post Office itself,[16] meant nothing more than what in Scotland was called a runner. Possibly because the idea of expedition was conveyed by the term "flying," flying packet came to be regarded as synonymous with express. "I despatch this by a flying pacquett," writes Lord Townshend to the Duke of Argyll in 1715; and again, "My lord, after writing what is above, a flying packet brings letters from Edinburgh of the 12th." "By the flying pacquett which arrived last night," writes Secretary Stanhope about the same date, "I received the honour of your Grace's of the 21st inst." Here, by flying packet is obviously meant express. And yet, curiously enough, this is a sense in which the postmasters-general never employed the term. By them it was always designed to signify the thing transmitted, and not the means of transmission. What they called a flying packet might be sent by ordinary post no less than by express; and when sending one by express they never failed to state that it was being so sent. "You are therefore," they write in 1706, "on the receipt of the bag so delivered to your care [_i.e._ a small bag containing letters for the Court], to dispatch the same imediately by a flying packet from Harwich to this office, and to send a labil therewith expressing the precise time of the arrival and your having dispatched the same per express." On receipt of the Holland mail, they write again in the following year, "You are to take out the Court letters, and to forward the same express by a flying packet directed to Mr. Frankland at the Post Office at Newmarket."
