A system of post, both for the despatch of letters and the conveyance of couriers, was introduced into Spain under Philip and Juana, that is, towards the end of the reign of our Henry VII.; whereas it was scarcely organised in England before the government of Cromwell. Spain, which in these matters, as well as in many others, was once so much in advance, is now compelled to borrow her improvements from those nations of which she formerly was the instructress: among these may be reckoned all travelling in carriages, whether public or private. The post-office for letters is arranged on the plan common to most countries on the Continent: the delivery is pretty regular, but seldom daily--twice or three times a-week. Small scruple is made by the authorities in opening private letters, whenever they suspect the character of the correspondence. It is as well, therefore, for the traveller to avoid expressing the whole of his opinions of the powers that be. The minds of men have been long troubled in Spain; civil war has rendered them very distrustful and guarded in their _written_ correspondence--“_carta canta_,” “a letter speaks.” There is the usual continental bother in obtaining post-horses, which results from their being a monopoly of government. There must be a passport, an official order, notice of departure, &c.; next ensue vexatious regulations in regard to the number of passengers, horses, luggage, style of carriage, and so forth. These, and other spokes put into the wheel, appear to have been invented by clerks who sit at home devising how to impede rather than facilitate posting at all. [Sidenote: PUBLIC CONVEYANCES.] Post-horses and mules are paid at the rate of seven reals each for each post. The Spanish postilions generally, and especially if well paid, drive at a tremendous pace, often amounting to a gallop; nor are they easily stopped, even if the traveller desires it--they seem only to be intent on arriving at their stages’ end, in order to indulge in the great national joy of then doing nothing: to get there, they heed neither ruts nor ravines; and when once their cattle are started the inside passenger feels like a kettle tied to the tail of a mad dog, or a comet; the wild beasts think no more of him than if he were Mazeppa: thus money makes the mare and its driver to go, as surely in Spain as in all other countries.
