The reason for this last exception is not far to seek. The established posts were few in number, and even where they existed in name they had fallen into disuse. The common carriers had thus become the chief carriers of letters, and Witherings, in the furtherance of his project, was anxious to disarm their opposition. This he had already attempted to effect by argument; and now, as a practical step in the same direction, he procured their exemption from the State monopoly. But what may have appeared and was probably intended to appear as a valuable concession was really no concession at all. The carrier took eight days to go 120 miles. By the posts the same distance was to be accomplished in a day and a night. The carrier's charge for a letter from Cambridge to London, a distance of about sixty miles, was 2d. A postage of 2d., according to Witherings's plan, was to a carry a letter for eighty miles. If the posts were to be both faster and cheaper than the common known carrier, it might safely be predicted that as a carrier of letters he could not long survive.
In October 1635 Witherings, having completed the necessary arrangements, proceeded to carry his plan into effect. The results he anticipated from it, as shewn in a memorandum which he delivered to the Secretary of State, were promotion of trade and intercourse and the cultivation of better relations with Scotland and Ireland. That the posts might one day be more than self-supporting, that they would become a source of revenue, does not appear to have entered into his calculations; or, if it did, his silence on the point would seem to shew that, as compared with the other advantages, he deemed it too insignificant to mention.
It was probably about this time that the practice of writing "Haste, post, haste" on the outside of letters began to be discontinued. The term "post," as here used, meant nothing more than the carrier or bearer of the letter; and an injunction to make the best speed he could, properly as it might be given to a messenger who had a particular letter to carry, would be altogether out of place if addressed to a general letter-carrier who was bound by his instructions not to exceed a given distance within a given time. "For thy life, for thy life" had sometimes been added, as in the case of Protector Somerset's letter to Lord Dacre. "To our very good Lord, the Lord Dacre, Warden of the West Marches, in haste; haste, post, haste, for thy life, for thy life, for thy life";[6] and it seems probable, if the barbarity of the punishments in those days is considered, that this was no empty threat. It was "on payn of lyfe" that, according to Sir Brian Tuke, all townships were to have horses ready for their Sovereign's service. Among the Ashburnham manuscripts is a letter from Sir Edward Nicholas to Sir John Hippisley, Lieutenant of Dover Castle, written in 1627 or eight years before the introduction of postage. This letter is endorsed by George Villiers, Duke of Buckingham, and the cover is inscribed "for His Majesty's special affairs; hast, hast, hast, post, hast, hast, hast, hast, with all possible speede." The absence of any threat in this instance may of course have been due to the individual character of the writer, but it is more agreeable to think of it as a sign of the advance of civilisation.
