Dykvelt's mission had succeeded so well that a pretence was soon found for sending another agent to continue the work which had been so auspiciously commenced. The new Envoy, afterwards the founder of a noble English house which became extinct in our own time, was an illegitimate cousin german of William; and bore a title taken from the lordship of Zulestein. Zulestein's relationship to the House of Orange gave him importance in the public eye. His bearing was that of a gallant soldier. He was indeed in diplomatic talents and knowledge far inferior to Dykvelt: but even this inferiority had its advantages. A military man, who had never appeared to trouble himself about political affairs, could, without exciting any suspicion, hold with the English aristocracy an intercourse which, if he had been a noted master of state craft, would have been jealously watched. Zulestein, after a short absence, returned to his country charged with letters and verbal messages not less important than those which had been entrusted to his predecessor. A regular correspondence was from this time established between the Prince and the opposition. Agents of various ranks passed and repassed between the Thames and the Hague. Among these a Scotchman, of some parts and great activity, named Johnstone, was the most useful. He was cousin of Burnet, and son of an eminent covenanter who had, soon after the Restoration, been put to death for treason, and who was honoured by his party as a martyr. The estrangement between the King of England and the Prince of Orange became daily more complete. A serious dispute had arisen concerning the six British regiments which were in the pay of the United Provinces. The King wished to put these regiments under the command of Roman Catholic officers. The Prince resolutely opposed this design. The King had recourse to his favourite commonplaces about toleration. The Prince replied that he only followed his Majesty's example. It was notorious that loyal and able men had been turned out of office in England merely for being Protestants. It was then surely competent to the Stadtholder and the States General to withhold high public trusts from Papists. This answer provoked James to such a degree that, in his rage, he lost sight of veracity and common sense. It was false, he vehemently said, that he had ever turned out any body on religious grounds. And if he had, what was that to the Prince or to the States? Were they his masters? Were they to sit in judgment on the conduct of foreign sovereigns? From that time he became desirous to recall his subjects who were in the Dutch service. By bringing them over to England he should, he conceived, at once strengthen himself, and weaken his worst enemies. But there were financial difficulties which it was impossible for him to overlook. The number of troops already in his service was as great as his revenue, though large beyond all precedent and though parsimoniously administered, would support.
