§ Sir F. SYKESasked the First Lord of the Admiralty on what date the device known as the string of mines was brought before the notice of his Department; and if he will give the name of the person responsible for the introduction of this device?
Commander Rt. Hon. B. M. EYRESMONSELLElectric contact mines (to which I understand the question to relate) has been used by the Admiralty years before the War. Their reintroduction during the War for use with nets was due to the late Admiral of the Fleet Sir A. K. Wilson, who designed special devices in connection with them. Orders for manufacture in quantities were given in April, 1915.
