Both the confederate Kings wished their compact to remain a secret while their brother Charles lived; and it probably would have remained secret, had it been confided only to the English and French Ministers.  But the institutions of the United Provinces were not well fitted for the purpose of concealment.  It had been necessary to trust so many deputies and magistrates that rumours of what had been passing at Loo got abroad.  Quiros, the Spanish Ambassador at the Hague, followed the trail with such skill and perseverance that he discovered, if not the whole truth, yet enough to furnish materials for a despatch which produced much irritation and alarm at Madrid.  A council was summoned, and sate long in deliberation.  The grandees of the proudest of Courts could hardly fail to perceive that their next sovereign, be he who he might, would find it impossible to avoid sacrificing part of his defenceless and widely scattered empire in order to preserve the rest; they could not bear to think that a single fort, a single islet, in any of the four quarters of the world was about to escape from the sullen domination of Castile.  To this sentiment all the passions and prejudices of the haughty race were subordinate.  “We are ready,” such was the phrase then in their mouths, “to go to any body, to go to the Dauphin, to go to the Devil, so that we all go together.”  In the hope of averting the threatened dismemberment, the Spanish ministers advised their master to adopt as his heir the candidate whose pretensions it was understood that France, England and Holland were inclined to support.  The advice was taken; and it was soon every where known that His Catholic Majesty had solemnly designated as his successor his nephew Francis Joseph, Electoral Prince of Bavaria.  France protested against this arrangement, not, as far as can now be judged, because she meant to violate the Treaty of Loo, but because it would have been difficult for her, if she did not protest, to insist on the full execution of that treaty.  Had she silently acquiesced in the nomination of the Electoral Prince, she would have appeared to admit that the Dauphin’s pretensions were unfounded; and, if she admitted the Dauphin’s pretensions to be unfounded, she could not, without flagrant injustice, demand several provinces as the price in consideration of which she would consent to waive those pretensions.  Meanwhile the confederates had secured the cooperation of a most important person, the Elector of Bavaria, who was actually Governor of the Netherlands, and was likely to be in a few months, at farthest, Regent of the whole Spanish monarchy.  He was perfectly sensible that the consent of France, England and Holland to his son’s elevation was worth purchasing at almost any cost, and, with much alacrity, promised that, when the time came, he would do all in his power to facilitate the execution of the Treaty of Partition.  He was indeed bound by the strongest ties to the confederates of Loo.
