If any doubt existed as to the encouragement given by
the Conserva- tives of this country and the despotic Powers of the Continent to the Miguelite party in Portugal, it would be removed by the publication of some intercepted correspondence of Senhor SARAIVA, the Usurper's agent in London, with the Duke DE CADAVAL and the Viscount DE SANTAREM. The Times of this morning contains three letters written by SARAIVA, in which he mentions, without reserve, the interviews of BOURMONT with Viscount BERESFORD and the Spanish Minister. The Duke of WELLINGTON is also represented as being most happy to bear of the Marshal's expedition to Portugal. The Ministers of the three Powers declared that they considered him as the champion of Legitimacy all over the world, and attached immense importance to his Success. After the defeat of the Miguelite squadron, SARAIVA says that he had conversed with the Ministers of the three Powers. and they all were very angry that it should have sailed before the Lord of the Isles and the United Kingdom had arrived with fresh supplies. The defence of Lisbon is stated to be all-important ; for the moment that the enemy possess themselves of it, he declares that there would be itothing more to hope for, as England would at once recognize the Queen.
