To Henry Johnson   23 December 1871

Down, | Beckenham, Kent.

Dec 23. 1871

My dear Johnson

I am much obliged for yr letter & very kind invitation; but I am sorry to say that the exertion of coming to Shrewsbury wd be far beyond my strength.1 I am particularly obliged to you for being willing to go to Wroxeter; for the observations will be difficult to make, & you may not succeed in finding sim〈ple〉 sections.2 I send by this p〈ost〉 my old paper, which will shew you a little what I am after. Now I have succeeded in ascertaining the exact weight annually cast up by earth worms over a square yard: it amounts to 16 110 tons of dry earth per acre.3

I thank you for telling me your family news & I wish it was in my 〈12 page missing

P.S. We are reading Miss Meteyard, but find it full of inacuracies & lament that she obtained letters never meant to be published.4

Footnotes

Johnson’s letter to CD has not been found.
CD cited Johnson for information about the depth of soil over the Roman ruins at Wroxeter in Earthworms, pp. 221–8.
CD probably sent a copy of a paper he read in 1837 before the Geological Society of London, ‘Formation of mould’. See also letter from L. C. Wedgwood, 20 November [1871] and n. 2.
Eliza Meteyard had published a biography of Josiah Wedgwood I (Meteyard 1865–6; see Correspondence vol. 13); she had used letters supplied by CD (see Correspondence vol. 13, letter from Eliza Meteyard, 17 November 1865).
