§ 45. Mr. Brockway
asked the Secretary of State for Air what services his Department receive from the Admiralty Compass Observatory at Ditton Park.
Mr. C. I. Orr-Ewing:
In addition to undertaking certain work placed on our behalf by the Ministry of Supply, the Observatory gives us technical advice on magnetic compasses and the magnetic survey of airfields. Some of our marine crews attend the Observatory for instruction on the maintenance of these compasses.
