Isabella's younger sister, the Infanta Fernanda; and pray, what possible objection could there be to that? The wily old King whispered into the chaste ears of Guizot the key to the secret; he had good reason to believe that the Duke of Cadiz was incapable of having children, and therefore the offspring of Fernanda would inherit the Spanish crown. Guizot rubbed his hands, and began at once to set the necessary springs in motion; but, of course, the whole scheme was very soon divulged and understood. The English Government took an extremely serious view of the matter; the balance of power was clearly at stake, and the French intrigue must be frustrated at all hazards. A diplomatic struggle of great intensity followed; and it occasionally appeared that a second War of the Spanish Succession was about to break out. This was avoided, but the consequences of this strange imbroglio were far-reaching and completely different from what any of the parties concerned could have guessed. In the course of the long and intricate negotiations there was one point upon which Louis Philippe laid a special stress--the candidature of Prince Leopold of Saxe-Coburg. The prospect of a marriage between a Coburg Prince and the Queen of Spain was, he declared, at least as threatening to the balance of power in Europe as that of a marriage between the Duc de Montpensier and the Infanta; and, indeed, there was much to be said for this contention. The ruin which had fallen upon the House of Coburg during the Napoleonic wars had apparently only served to multiply its vitality, for that princely family had by now extended itself over Europe in an extraordinary manner. King Leopold was firmly fixed in Belgium; his niece was Queen of England; one of his nephews was the husband of the Queen of England, and another the husband of the Queen of Portugal; yet another was Duke of Wurtemberg. Where was this to end? There seemed to be a Coburg Trust ready to send out one of its members at any moment to fill up any vacant place among the ruling families of Europe. And even beyond Europe there were signs of this infection spreading. An American who had arrived in Brussels had assured King Leopold that there was a strong feeling in the United States in favour of monarchy instead of the misrule of mobs, and had suggested, to the delight of His Majesty, that some branch of the Coburg family might be available for the position. That danger might, perhaps, be remote; but the Spanish danger was close at hand; and if Prince Leopold were to marry Queen Isabella the position of France would be one of humiliation, if not of positive danger. Such were the asseverations of Louis Philippe. The English Government had no wish to support Prince Leopold, and though Albert and Victoria had some hankerings for the match, the wisdom of Stockmar had induced them to give up all thoughts of it. The way thus seemed open for a settlement: England would be reasonable about
