From Amy Ruck to Horace Darwin   [20 January 1872]1

Pantlludw, | Machynlleth.

Dear Horace

I am afraid I have nothing worth telling about worms. I have been rather in despair   this seems such a bad country for them as a “worm casting” is quite a rare sight   even on our croquet ground where one might expect to see them, there is very few. Atty2 declares there are a dozen moles to every worm here— However on the top of the Hill there are some steep slopes ploughed about 50 or 60 years ago & we have done some digging & measuring there with these results— the furrows going chiefly crossways—

[DIAG HERE]

We found that the fine soil at the top of the slope was always shallower, being in the furrows at the top 212 inches, at the bottom 412; & that there was always about half an inch difference in the depth of the soil in the ridge & in the furrow, that in the furrow being deepest. We tried a good many times & always found this difference—

It is rare to find furrows running down a slope, but we came across a few in a basin, last ploughed during the Peninsular War—& there they almost disappeared at the bottom—the depth of the furrow between the ridges being at the top 412in. at the bottom 1in.3 Papa says, there is a place near his old home Newington called ‘Worm Dale, where they do wonders—4 Dicky & Lenny5 might go & look at it.

My thanks to you for wading through this. | ARR.
