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
