_Spain Revisited_, although we cannot think it at all equal to the _American in England_ for picturesque and vigorous description (which we suppose to be the forte of Lieutenant Slidell) yet greatly surpasses in this respect most of the books of modern travels with which we now usually meet. A moderate interest is sustained throughout--aided no doubt by our feelings of indignation at the tyranny which would debar so accomplished a traveller as our countryman from visiting at his leisure and in full security a region so well worth visiting as Spain. It appears that Ferdinand on the 20th August, 1832, taking it into his head that the Lieutenant's former work "A Year in Spain" (esta indigesta produccion) esta llena de falsedades y de groceras calumnias contra el Rey N. S. y su augusta familia, thought proper to issue a royal order in which the book called _un ano en Espana_ was doomed to seizure wherever it might be found, and the clever author himself, under the appellation of the Signor Ridell, to a dismissal from the nearest frontier in the event of his anticipated return to the country. Notwithstanding this order, the Lieutenant, as he himself informs us, did not hesitate to undertake the journey, knowing that, subsequently to the edict in question, the whole machinery of the government had undergone a change, having passed into liberal hands. But although the danger of actual arrest on the above-mentioned grounds was thus rendered comparatively trivial, there were many other serious difficulties to be apprehended. In the Basque Provinces and in Navarre the civil war was at its height. The diligences, as a necessary consequence, had ceased to run; and the insurgents rendered the means of progressing through the country exceedingly precarious, by their endeavors to cut off all communications through which the government could be informed of their manœuvres. The post-horses had been seized by the Carlist cavalry to supply their deficiencies, "and only a few mules remained at some of the post-houses between Bayonne and Vitoria." The following sketch of an ass-market at Tordesillas seems to embody in a small compass specimens of nearly all the excellences as well as nearly all the faults of the author.
