It would occupy too much space to specify the infinite lines which are in contemplation, which may be described when completed. Suffice it to say, that they almost all are to be effected by the iron and gold of England. However this _estrangerismo_, this influence of the foreigner, may offend the sensitive pride, the _Españolismo_ of Spain, the power of resistance offered by the national indolence and dislike to change, must be propelled by British steam, with a dash of French revolution. Yet our speculators might, perhaps, reflect that Spain is a land which never yet has been able to construct or support even a sufficient number of common roads or canals for her poor and passive commerce and circulation. The distances are far too great, and the traffic far too small, to call yet for the rail; while the geological formation of the country offers difficulties which, if met with even in England, would baffle the colossal science and extravagance of our first-rate engineers. Spain is a land of mountains, which rise everywhere in Alpine barriers, walling off province from province, and district from district. These mighty cloud-capped _sierras_ are solid masses of hard stone, and any tunnels which ever perforate their ranges will reduce that at Box to the delving of the poor mole. You might as well cover Switzerland and the Tyrol with a net-work of _level_ lines, as those caught in the aforesaid net will soon discover to their cost. The outlay of this up-hill work may be in an inverse ratio to the remuneration, for the one will be enormous, and the other paltry. The parturient mountains may produce a most musipular interest, and even that may be “deferred.” [Sidenote: DIFFICULTIES OF RAILROADS.]
