That is probably the cleverest and most entertaining suggestion I have had in this connection. You have a sense of humour, Sir. Zennor, Chun and Mulfra quoits a have been under study for some time and this summer elementary field work is scheduled. Form follows function, and Zennor shows strong possibilities that it might be a 'sister' to Trethevy, in terms of astronomical usage. Lanyon has been ignored because it has been re-erected. To use it as a 'control' is impossible, as you know, but the notion is amusing and instructive.
Thank you so much. If there are neolithic jokes to be made it looks like we are making them.
Laughed out loud. Thanks.
