To Archibald Geikie   27 December [1871]

Summary

His admiration for the papers of AG [see 8119].

Relates his recent discovery that earthworms have brought to surface no less than 161 tons of dry earth over an area of 10 acres, thus creating the conditions for significant denudation. Would welcome information about the persistence of ridges and furrows in old pasture lands ploughed centuries ago. Do they run down the slopes or transversely? Refers to [A. C.] Ramsay, [James] Croll, Elie de Beaumont, and [Henry] Johnson.
