For at this same time the Beaconsfield Cabinet had been treating secretly with the Sublime Porte. When Lord Salisbury found out that Russia would not abate her demands for Batoum, Ardahan, and Kars, he sought to safeguard British interests in the Levant by acquiring complete control over the island of Cyprus. His final instructions to Mr. Layard to that effect were telegraphed on May 30, that is, on the very day on which peace with Russia was practically assured[170]. The Porte, unaware of the fact that there was little fear of the renewal of hostilities, agreed to the secret Cyprus Convention on June 4; while Russia, knowing little or nothing as to Britain's arrangement with the Porte, acceded to the final arrangements for the discussion of Turkish affairs at Berlin. It is not surprising that this manner of doing business aroused great irritation both at St. Petersburg and Constantinople. Count Shuvaloff's behaviour at the Berlin Congress when the news came out proclaimed to the world that he considered himself tricked by Lord Beaconsfield; while that statesman disdainfully sipped nectar of delight that rarely comes to the lips even of the gods of diplomacy. [Footnote 170: Parl. Papers, Turkey, No. 36 (1878). See, too, _ibid_. No. 43.] The terms of the Cyprus Convention were to the effect that, if Russia retained the three districts in Asia Minor named above, or any of them (as it was perfectly certain that she would); or if she sought to take possession of any further Turkish territory in Asia Minor, Great Britain would help the Sultan by force of arms. He, on his side assigned to Great Britain the island of Cyprus, to be occupied and administered by her. He further promised "to introduce necessary reforms, to be agreed upon later between the two Powers, into the government, and for the protection of the Christian and other subjects of the Porte in these territories." On July I Britain also covenanted to pay to the Porte the surplus of revenue over expenditure in Cyprus, calculated upon the average of the last five years, and to restore Cyprus to Turkey if Russia gave up Kars and her other acquisitions[171].
