This volume concerns British policy regarding the south-eastern boundaries of Saudi Arabia.

It documents preparations for negotiations with the Saudi Government, and includes interdepartmental discussion regarding the approach that the British Government should take in reaching a settlement with Ibn Saud [‘Abd al-‘Azīz bin ‘Abd al-Raḥmān bin Fayṣal Āl Sa‘ūd] over the demarcation of the boundaries.

The areas of territory discussed include that which separates Saudi Arabia and the Aden Protectorate in the south, that which extends to the Sultanate of Muscat and Oman in the south-east, and the area extending to the south of Qatar in the east.

Reference is made to the 'blue line' and the 'violet line' – boundary lines that formed part of the Anglo-Ottoman Conventions, concluded in 1913 and 1914 respectively.

The correspondence includes discussion of the following:

• The likely consequences of not settling on defined boundaries.
• The extent of territory that the British should be prepared to include in any concession made to Ibn Saud.
• The legal distinction between personal and territorial sovereignty.
• References made by Fuad Bey Hamza (Deputy Saudi Minister for Foreign Affairs) during conversations with Sir Andrew Ryan (His Majesty's Minister at Jedda), regarding certain assurances made by Sir Henry McMahon to King Hussein of the Hejaz [Ḥusayn bin ‘Alī al-Hāshimī] in 1915, on the subject of Arab independence (a summary of a letter from King Hussein to McMahon, together with a copy of McMahon's reply, is included in the volume).
• Tribal history in Trucial Oman between 1918 and 1934.
• The Koweit [Kuwait] blockade.
• The boundaries of a proposed 'desert zone', roughly following the edge of the sands of the Ruba al Khali and considered by the British as a possible concession but later abandoned.
• Abu Dhabi's claims to Odeid [Al ‘Udayd, Saudi Arabia] and Banaiyan [Bi’r Bunayyān, Saudi Arabia].

The volume features the following principal correspondents: the Political Agent, Bahrain (Percy Gordon Loch); the Political Resident in the Persian Gulf (Lieutenant-Colonel Trenchard Craven William Fowle); His Majesty's Minister at Jedda (Sir Andrew Ryan); the Secretary of State for the Colonies (Philip Cunliffe-Lister); Bernard Rawdon Reilly (Chief Commissioner, Aden, but referred to in the correspondence as Resident); officials of the Foreign Office, the Colonial Office, the India Office, the War Office, the Air Ministry, and the Government of India's Foreign and Political Department.

In addition to correspondence, the volume contains a sketch map and a copy of draft minutes of a meeting of the Committee of Imperial Defence's Standing Official Sub-Committee for Questions Concerning the Middle East, dated 15 April 1935.

The volume includes a divider which gives a list of correspondence references contained in the volume by year. This is placed at the back of the correspondence (folio 4).
