Summary

Letter no:  DCP-LETT-8112

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.

Summary

Is obliged for valuable letter [see 8123] and encloses queries about the manner of gradual obliteration of ridges or furrows in old pasture lands in various parts of England.

Gives details of his experiment to test his observations of the downward flow of worm-casts.

Refers to [Lyon] Playfair, [A. C.] Ramsay, and AG’s edition of [J. B.] Jukes, [A student’s manual of geology, 3d ed., 1872].
