Caroline entered with manifest enjoyment upon the duties of her office, and discharged them with great ability; she had so long known the essence of power that it was easy for her to adapt herself to its outward manifestation. Townshend, who was jealous of Walpole’s favour with the Queen, endeavoured to induce the King to modify her powers as Regent, and urged him to send a despatch to that effect from the Hague, but the King, though he listened, declined to do so; in fact, he knew better than any one else that his interests were safe in his consort’s hands. [Illustration: LETTER OF QUEEN CAROLINE TO THE KING OF FRANCE.] The Queen-Regent had the power of opening and proroguing Parliament, signifying the royal assent to acts and measures, appointing bishops, and of making other important appointments; she also received the foreign ambassadors and envoys as though she were the King, and corresponded with foreign sovereigns. Queen Caroline was especially careful to cultivate and strengthen the good understanding between England and France, and she wrote several letters to the King of France, and sent him a present of a dozen hogsheads of perry and cider.[39] The most important negotiation in foreign affairs was the Treaty of Seville, which was practically concluded during Caroline’s regency, though it was not signed until a little later (November 9th, 1729). This treaty terminated the long dispute between England and Spain. By its provisions, English trade to America, which had been interrupted, was restored. England was given back all that Spain had captured during the war, and the Asiento Treaty (or contract for supplying negroes, of establishing certain factories, and of sending one ship to the South Sea) was confirmed to the South Sea Company. But the most important feature of the treaty was that Gibraltar was tacitly relinquished by Spain. It would be too much to claim for Caroline the credit of the cession of Gibraltar to England, but there is no doubt that her wise and temperate counsels, and her anxiety not to give needless offence to Spanish susceptibilities by mentioning the fortress by name, materially aided William Stanhope, the English plenipotentiary at Madrid, in conducting the difficult and delicate negotiations which resulted in the Treaty of Seville. Gibraltar was a question which touched Spanish pride very nearly, and to see a fortress on its own shores held and garrisoned by England was as great a humiliation to Spain as England’s possession of Calais had once been to France.
