To A. C. Ramsay   21 December [1871]1

Down, | Beckenham, Kent. [6 Queen Anne Street, London.]

Dec. 21

My dear Ramsay

If you are able to judge of amount of subsidence of the flag-stones, please observe whether anything indicates that the subsidence is not due to their having been originally laid on yielding earth.—2 Are they continued under cover where worms would not act? About what sized squares are the stones? What is age of your House? I think I understood that you had often actually seen worm-castings over the joints.— I have written to Prof. Geikie.3

Yours very sincerely | Ch. Darwin

The year is established by the relationship between this letter and the letter from A. C. Ramsay, 27 December 1871.
Ramsay’s letter to CD on this subject has not been found. He had evidently written about a pavement between his house and his garden that had subsided owing to the activity of worms (see Earthworms, pp. 192–3).
