But, to quit details, the broad results were these. Palmer, when introducing his plan, had promised security and despatch; but not economy. On the contrary, he had made no secret of his opinion that the use of mail-coaches would involve a considerable increase of expense. The result was a surprise even to himself. Before 1784 the annual allowance for carrying the mails ranged from £4 to £8 a mile, £8 being paid where the mails were heavy--as, for instance, on the Great North Road from London as far as Tuxford. In 1792 the terms on which the mails were carried were exemption from tolls and 1d. a mile each way, or an annual allowance of a little more than £3 a mile. Palmer had estimated the total cost of his plan at £30,000 a year. The actual cost only slightly exceeded £12,000. Hardly less reason had he to congratulate himself on the score of security and despatch. Before 1784 scarcely a week passed without the mails on one road or another being robbed. So great had the scandal become that the Post Office built a model cart--a cart wholly constructed of iron and reputed to be robber-proof. This cart had not long begun to run before it was stopped by highwaymen and rifled of its contents. In 1792 eight years had passed since the introduction of Palmer's plan; and during this period not a single mail-coach had been either stopped or robbed. This immunity from robbery was in more ways than one equivalent to a further saving. Before 1784 heavy expenses were incurred annually for prosecutions. One trial alone, a trial which made no little noise at the time, namely that of the brothers Weston, cost no less than £4000. This source of expense had now, of course, disappeared. As regards despatch, before 1784 the post travelled between five and six miles an hour. In 1792 the mail-coaches were travelling about seven miles an hour. Telford had not yet levelled the hills nor Macadam paved the roads; and rollers were unknown. A speed of seven miles an hour at the end of the last century was probably far more trying to horses than a speed of ten miles an hour later on. It would be beyond our province to inquire--interesting as the inquiry would be--to what extent the exchange of commodities between town and town dates from the introduction of mail-coaches; and whether it was not at this period that, with some noted exceptions, the local repute which certain towns enjoyed for the manufacture of particular articles began to spread. Ours is a humbler purpose; or we might be tempted even to contend that Palmer's plan, by the facilities it afforded for intercourse, exercised an influence--slow it may be, but none the less sure--upon the habits and condition of the people.
