To descend to the roads of the peninsular earth, the principal lines are nobly planned. These geographical arteries, which form the circulation of the country, branch in every direction from Madrid, which is the centre of the system. The road-making spirit of Louis XIV. passed into his Spanish descendants, and during the reigns of Charles III. and Charles IV. communications were completed between the capital and the principal cities of the provinces. These causeways, “_Arrecifes_”--these royal roads, “_Caminos reales_”--were planned on an almost unnecessary scale of grandeur, in regard both to width, parapets, and general execution. The high road to La Coruña, especially after entering Leon, will stand comparison with any in Europe; but when Spaniards finish anything it is done in a grand style, and in this instance the expense was so enormous that the king inquired if it was paved with silver, alluding to the common Spanish corruption of the old Roman via lata into “camino de _plata_,” of plate. This and many of the others were constructed from fifty to seventy years ago, and very much on the M’Adam system, which, having been since introduced into England, has rendered our roads so very different from what they were not very long since. The war in the Peninsula tended to deteriorate the Spanish roads--when bridges and other conveniences were frequently destroyed for military reasons, and the exhausted state of the finances of Spain, and troubled times, have delayed many of the more costly reparations; yet those of the first class were so admirably constructed at the beginning, that, in spite of the injuries of war, ruts, and neglect, they may, as a whole, be pronounced equal to many of the Continent, and are infinitely more pleasant to the traveller from the absence of pavement. The roads in England have, indeed, latterly been rendered so excellent, and we are so apt to compare those of other nations with them, that we forget that fifty years ago Spain was in advance in that and many other respects. Spain remains very much what other countries were: she has stood on her old ways, moored to the anchor of prejudice, while we have progressed, and consequently now appears behind-hand in many things in which she set the fashion to England.
