the least, well lined with baize or cotton, so as not to injure the letters." It also rested with the different postmasters to furnish the couriers with "_hornes_ to sound and blowe as oft as the post meets company, or at least four times in every mile."[11] Thus arose a custom which, under slightly different circumstances, was strictly observed in the days of mail-coaches. It will be readily observed that in the arrangements of the packet-post there was nothing to prevent its being extensively used, except the important restrictions which the King put upon its use. During the reign of James nothing but the despatches of ambassadors were allowed to jostle the Government letters in the leather bags, "lined with baize or cotton," of "the post for the packet." It was not until Charles the First had succeeded his father, that this post came to be used, under certain conditions, by merchants and private persons. It was during the reign of James the First that the Government secured, and kept for a hundred years, certain privileges with respect to the hiring of post-horses. We have seen that the royal couriers, travelling with despatches by either of the two posts, had priority of claim to sufficient horses and proper accommodation on their journeys. They also settled, by order in Council, that any person, whether travelling on the business of the Government or not, should, if furnished with warrants from the Council, have prior claim to private individuals, over post-horses and proper entertainment, demanding them in the name of the King. In a warrant of Council, for instance, dated Whitehall, May 12, 1630, we find the Privy Council ordering all postmasters to furnish Sir Cornelius Vermuyden with horses and guides to enable him to ride post from London to Boston, and thence to Hatfield, where he was engaged in draining the royal chase for the King.[12]
