IV. ANOTHER very considerable branch of the revenue is levied with greater chearfulness, as, instead of being a burden, it is a manifest advantage to the public. I mean the post-office, or duty for the carriage of letters. As we have traced the original of the excise to the parliament of 1643, so it is but justice to observe that this useful invention owes it's birth to the same assembly. It is true, there existed postmasters in much earlier times: but I apprehend their business was confined to the furnishing of posthorses to persons who were desirous to travel expeditiously, and to the dispatching extraordinary pacquets upon special occasions. The outline of the present plan seems to have been originally conceived by Mr Edmond Prideaux, who was appointed attorney general to the commonwealth after the murder of king Charles. He was a chairman of a committee in 1642 for considering what rates should be set upon inland letters[o]; and afterwards appointed postmaster by an ordinance of both the houses[p], in the execution of which office he first established a weekly conveyance of letters into all parts of the nation[q]: thereby saving to the public the charge of maintaining postmasters, to the amount of 7000_l._ _per annum_. And, his own emoluments being probably considerable, the common council of London endeavoured to erect another post-office in opposition to his, till checked by a resolution of the commons[r], declaring, that the office of postmaster is and ought to be in the sole power and disposal of the parliament. This office was afterwards farmed by one Manley in 1654[s]. But, in 1657, a regular post-office was erected by the authority of the protector and his parliament, upon nearly the same model as has been ever since adopted, with the same rates of postage as were continued till the reign of queen Anne[t]. After the restoration a similar office, with some improvements, was established by statute 12 Car. II. c. 35. but the rates of letters were altered, and some farther regulations added, by the statutes 9 Ann. c. 10. 6 Geo. I. c. 21. 26 Geo. II. c. 12. and 5 Geo. III. c. 25. and penalties were enacted, in order to confine the carriage of letters to the public office only, except in some few cases: a provision, which is absolutely necessary; for nothing but an exclusive right can support an office of this sort: many rival independent offices would only serve to ruin one another. The privilege of letters coming free of postage, to and from members of parliament, was claimed by the house of commons in 1660, when the first legal settlement of the present post-office was made[u]; but afterwards dropped[w] upon a private assurance from the crown, that this privilege should be allowed the members[x]. And accordingly a warrant was constantly issued to the postmaster-general[y], directing the allowance thereof, to to [Transcriber's Note: duplicate word] the extent of two ounces in weight: till at length it was expressly
