After his appointment, Mr. Anderson directed his attention to the establishment of Horse Posts on the Western Road from Edinburgh. The first regular Horse Post in Scotland appears to have been from Edinburgh to Stirling; it started for the first time on the 29th November 1715. It left Stirling at two o'clock afternoon, each Tuesday, Thursday, and Saturday, and reached Edinburgh in time for the Night Mail to England. In March 1717, the first Horse Post between Edinburgh and Glasgow was established, and we have the details of the arrangement in a memorial addressed to Lord Cornwallis and James Craggs, who jointly filled the office of Postmaster-General of Great Britain. The memorial states, that the "Horse Post will set out for Edinburgh each Tuesday and Thursday, at eight o'clock at night, and on Sunday about eight or nine in the morning, and be in Glasgow (a distance of thirty-six miles by the post road of that time) by six in the morning on Wednesday and Friday in summer, and eight in winter, and both winter and summer will be on Sunday night." There appears to have been a good deal of negotiation connected with the settlement of this Post, in which the Provost and Bailies of Glasgow took part. After some delay, the matter appears to have been arranged to the satisfaction of all parties. A proposition was made at this time to establish a Horse Post between Edinburgh and Aberdeen, at a cost of £132, 12s. per annum, to supersede the Foot Posts, which were maintained at a cost of £81, 12s. The scheme, however, appears not to have been entertained at that time by the Post Office authorities. At this period (1715), it took double the time for the Mail to perform the journey between London and Edinburgh that it did in the middle of the seventeenth century. When the Mail was first established by Charles I. in 1636, three days was the time allowed for the special couriers to perform the journey between Edinburgh and London; in 1715, it required six days for the Post to perform the same journey. This can easily be seen by examining the post marks on letters of that time. In the year 1715, Edinburgh had direct communication with sixty post towns in Scotland, and in the month of August, the total sum received for letters passing to and from these offices and Edinburgh, was £44, 3s. 1d. The Postage on letters to and from London in the same month amounted to £157, 3s. 2d., and the Postage for letters per the London road, amounted to £9, 19s., making the total sum for letters to and from Edinburgh, during that month, amount to £211, 5s. 3d.--equal to £2535, 3s. per annum.[25]
