May I thank the Solicitor-General for what he has said? All that is necessary is for an earthwork to be left alone. A man farming land on which there is an earthwork may, quite innocently, cause damage to it in the ways I have enumerated. I wish to reinforce what has been said by the right hon. Member for Bishop Auckland (Mr. Dalton), and I hope that this matter will receive sympathetic consideration. It is rather misleading to refer to "ancient monuments" in this connection as people visualise a structure. But all that is necessary is that these earthworks shall be left alone.
