IV.—Hertfordshire Subsidences

Published online by Cambridge University Press:  01 May 2009

Extract

Subsidences are by no means unusual amongst the arable lands in the Chalk districts of this county. No one, who has travelled in these parts, can have failed to notice the numerous holes and dells dotted about the fields in all directions, many of which have fallen in, or will do so,incourse of time. Nearly all of them mark spots where the Chalk has been dug up for chalking the land, which is then said to work better.
