§ Sir S. McAddenasked the Secretary of State for the Environment what trials are being arranged which will help the Maplin Development Authority to design sea walls needed to protect the third London airport reclamation works at Maplin.
§ Mr. Eldon GriffithsA contract has recently been placed for the construction on the Maplin Sands of a trial bank built of gravels dredged from the Thames and offshore from Hastings. A commission has also been placed with a consulting engineer to study the possibilities and economics of using other material including colliery waste should gravel not prove satisfactory. None of this material will be brought to the site by road; it will all be brought by sea.
