Abstract: This memorandum was prepared by John Gilbert Laithwaite in May 1934 and comments on the history of the concession of red oxide on Abu Musa [Abū Mūsá]. The concession was granted in April 1898 by Sheikh Salim bin Sultan [Sālim bin Sulṭān Āl Qāsimī] while acting as Regent. On his return the ruling Sheikh, Sagar bin Khalid [Ṣaqr bin Khālid Āl Qasimī], saw nothing objectionable it. The concession was made to Hassan Samaiyah, his son Abdullah and Isa bin Adul Latif [‘Īsá bin ‘Abd al-Laṭīf], son of the Residency Agent at Sharjah. The concessionaires were described as British subjects and the interest in the concession of Herr Wonckhaus [Robert Wonckhaus] and Frank Clarke Strick is detailed. The memorandum also describes the claim of the Persian Government to Abu Musa and notes that the concession granted for five years to Frank Clarke Strick in January 1923 expired at the beginning of 1928 but there is nothing to show that any application was made for a renewal.Physical description: The main foliation sequence commences at the first folio and terminates at the last folio; these numbers are written in pencil, are circled, and are located in the top right corner of the recto side of each folio.
