After expressing his mind thus freely in regard to James and his policy, he then gave the Ambassador a word of caution in characteristic fashion. "Cogita," he said, "but beware of censuring his Majesty's projects. I do not myself mean to censure them, nor are they publicly laughed at here, but look closely at everything that comes from Brussels, and let me know with diligence." And even as the Advocate was endeavouring with every effort of his skill and reason to stir the sluggish James into vigorous resolution in behalf of his own children, as well as of the great cause of Protestantism and national liberty, so was he striving to bear up on his strenuous shoulders the youthful king of France, and save him from the swollen tides of court intrigue and Jesuitical influence fast sweeping him to destruction. He had denounced the recent and paltry proposition made on the part of the League, and originally suggested by James, as a most open and transparent trap, into which none but the blind would thrust themselves. The Treaty of Xanten, carried out as it had been signed and guaranteed by the great Catholic powers, would have brought peace to Christendom. To accept in place of such guarantee the pledge of a simple soldier, who to-morrow might be nothing, was almost too ridiculous a proposal to be answered gravely. Yet Barneveld through the machinations of the Catholic party was denounced both at the English and French courts as an obstacle to peace, when in reality his powerful mind and his immense industry were steadily directed to the noblest possible end--to bring about a solemn engagement on the part of Spain, the Emperor, and the princes of the League, to attack none of the Protestant powers of Germany, especially the Elector-Palatine, but to leave the laws, liberties, and privileges of the States within the Empire in their original condition. And among those laws were the great statutes of 1609 and 1610, the "Majesty-Letter" and the "Compromise," granting full right of religious worship to the Protestants of the Kingdom of Bohemia. If ever a policy deserved to be called truly liberal and truly conservative, it was the policy thus steadily maintained by Barneveld. Adverting to the subterfuge by which the Catholic party had sought to set aside the treaty of Xanten, he instructed Langerac, the States' ambassador in Paris, and his own pupils to make it clear to the French government that it was impossible that in such arrangements the Spanish armies would not be back again in the duchies at a moment's notice. It could not be imagined even that they were acting sincerely.
