This and other events at length convinced the stupid and ungrateful Emperor that the war was hopeless. Russia had as good as deserted him; Prussia, so lately won over, was again wavering; Sweden and Holland had joined the allies; and Spain, so far from helping him, could not drive the enemy from a corner of its own territory. He therefore listened to terms of peace which were offered by the allies through the pacific medium of Fleury, and the preliminaries were signed at Paris by the Austrian Ambassador on the 31st of May with England, France, and Holland. The Emperor agreed to suspend for seven years the charter of the Ostend Company; to confirm all treaties previous to 1725; and to refer any other objects of dispute to a general congress. Several articles were introduced regarding Spain. The English consented to withdraw the fleet of Admiral Hosier from blockading Porto Bello, so that the galleons could return home; the siege of Gibraltar was to be discontinued, and the _Prince Frederick_ to be restored. These articles were signed by the Spanish Ambassador at Paris, but Philip himself never ratified them, and England and Spain continued in a dubious state of neither peace nor war. [Illustration: FIVE-SHILLING PIECE OF THE SOUTH SEA COMPANY.] [Illustration: FIVE-GUINEA PIECE OF GEORGE I.] Whilst Walpole was thus labouring to secure the peace of Europe, Bolingbroke was as industriously at work to undermine him. He had cultivated his intimacy with the Duchess of Kendal still more diligently, and by liberal bribes, and more liberal promises if he succeeded in once more regaining power, he had brought her to exert her influence with the king in his favour. This most sordid and rapacious of mistresses, who looked on England only as a country to be managed for her benefit, ventured at length to put into the king's hand a memorial drawn up for her by Bolingbroke, demonstrating that the country must be absolutely ruined if Walpole continued in office. The stratagem was too palpable. Whilst she talked only, her suggestions might pass for her own, but the style of the document must have at once caused the king's suspicion of its true source. He put the paper into Walpole's hand. Walpole, after interrogating the two Turks, who were always in attendance on the king, and on their denying all knowledge of the means by which the missive reached the royal person, went directly to the Duchess and charged her with the fact. She did not deny it. Walpole advised the king to admit Bolingbroke to the audience which he solicited in the memorial, trusting that the king's dislike of him would prevail in the interview. The result appeared to be of that kind; nevertheless, Walpole was far from being secure in his own mind. He knew that the mistress would be continually returning to the charge in favour of her friend and paymaster, though she enjoyed a pension from Government of seven thousand five hundred pounds; and he even
