The ministers charged with the control of the Post Office were the Lords of the Treasury. How little the postmasters-general were left to act on their own responsibility will best be shewn by examples. Warwick, according to the computation of those days, was sixty-seven miles from London; but letters for that town passed through Coventry, thus traversing a distance of eighty miles. And not only was the route a circuitous one but it involved an additional charge for postage, the rates for a single letter being, for eighty miles, 3d., and for less than eighty, 2d. The postmasters-general desired to send the letters direct; but even so simple a matter as this they were not competent to decide for themselves. A change of route involved a reduction of charge; and a reduction of charge might affect the King's receipts. Before, therefore, the route could be altered, the King's assent had to be signified through his appointed ministers. In 1696 a post was established between Exeter and Bristol. This was the first cross-post set up by authority in the British Isles. It ran twice a week, leaving Exeter on Wednesdays and Saturdays at four in the afternoon, and arriving at Bristol at the same hour on the following days. From Bristol the return post, which went on Mondays and Fridays, started at ten in the morning. But in this case as in the other, the postmasters-general had not the power to act of their own motion. Hitherto letters between the two towns had passed through London, and so had been liable to a double rate of postage, to one rate of 3d. from Exeter to London, and to another rate of equal amount from London to Bristol, or 6d. altogether. For the future, the towns being less than eighty miles apart, the charge would be 2d. Large as this reduction was, the postmasters-general strongly advocated it. The existing post, they said, was both tedious and costly, and had been little used in consequence. A direct post, it was true, would require a small outlay to start it; but, this outlay notwithstanding, the post was certain to prove remunerative. Increase facilities for correspondence, and correspondence would assuredly follow. Besides, it would promote trade and be an inestimable boon to the public generally. To these representations the Treasury yielded; and before three years were over, the postmasters-general had the satisfaction of reporting that the new post was producing a clear profit of more than £250 a year. But complaisant as the Treasury had been on this occasion, their co-operation was fitful and uncertain. The Post Office could not advance a step without incurring some trifling expense; and the Treasury only too often acted as if to save expense, however trifling, were the highest proof of statesmanship.
