My dear Charles
Here is what further information my father has been able to procure for you. I do not
know that it is more decisive than what you had before, but it is satisfactory as
corroborative— He has been endeavouring to ascertain by means of old Slaney
the parish clerk some the dates more accurately, but he believes you may rely on them
within a year. I believe it is the date of 1825 in his first facts he
means— He desires me to tell you he is very much struck with your hypothesis
of chalk being made by fishes— if fish made Chalk
Hill I dont see why worms may not make a meadow— I suppose in William
Dabb's old croft the worms had done their work before it was
ploughed—but 12 inches is certainly as much as one can think them
capable of even in 80 years or so.— We are very much obliged to you
for sending us a copy of y
I went & paid Clayton a visit before Caroline went to Shrewsbury in such a rainy day that we could only sit over the fire—& the room looked so much larger & more comfortable than when I saw it before with all the chairs & tables in the middle of the floor, that I expect when it has got a clean face & some new chintz curtains it will put all it's detractors to silence—but the pleasantest was to see Caroline looking so very comfortable in it. The Dr is coming there tomorrow—but he wont be so rash I should think as to go up stairs—
Goodbye my dear Charles—my mother desires me to tell you she hopes you will come very soon again— | Your affectionate cousin | S E W.
My father is out, but I believe I have given you his message right about the date.
William Dabbs's bog meadow—the soil peaty & has been in
grass several years—was sanded on the grass surface so as to be completely
covered & to look red all over, probably about
William Dabbs's old croft—peaty soil—arable—was marled when his mother was a girl who would now have been about 90— An imperfect stratum of marl but sufficienty distinct to be traced & the depth measured with confidence, is found at 12 inches in one place, & 14 inches in another, the difference corresponding with the difference of the level of the surface produced by ploughing—the cop of the ridge being taken in one trial, and the rain (I believe a provincial term for the low place between the ridges formed by throwing the furrows each way) in another— The marl is apparently sunk to the natural stratum of hard white sand which lies under the peat in this valley.
The depth of ploughing varies from 4 to 8 inches, both extremes being rare.

The date of 1825 opposite relates to the Lawn where we first dug for lime. Slaney has a book in which he keeps an account of his carrying for me & in which he finds the field in question limed in the early spring of 1825—so it is 121/2 years ago— I have only just learnt this & even now I have not been able to see Slaney— If I find any error I will write again before Wednesday—
- f1 385.f1In the first version of his paper ‘On the formation of mould’, read 1 November 1837 at the Geological Society (Collected papers 1: 49–53), CD had included a hypothesis that chalk was produced from coral by the digestive action of marine animals. The statement was omitted from the version printed in the Transactions of the Geological Society (ibid., p. 53). (See letter from William Buckland to the Geological Society of London, 9 March 1838, and n. 2.)
- f2 385.f2CD had attributed the earthworm explanation to Josiah Wedgwood II. The information his uncle provided in this letter was added as a note to the accounts in both the Proceedings and the Transactions of the Geological Society (Collected papers 1: 52).
- f3 385.f3Andrew Crosse experimented on electro-crystallisation. In 1837 he gained notoriety when he announced that individuals of a species of Acarus appeared in the course of an experiment he was carrying out with a voltaic battery.
- f4 385.f4Staffordshire parish and hamlet, 2 miles south-west of Stoke-on-Trent, the site of the Etruria potteries. Caroline and Josiah Wedgwood III lived there before taking up residence at Leith Hill Place near Dorking, Surrey.
