I wonder could this be the same chalk pit mentioned in this wonderful epitaph in Lancing Churchyard?
Sacred to the Memory of John Gomery aged 16 years William Harwood aged 15 and James Tate aged 10 who were killed by the falling-in of a Chalk Pit on Lancing Downs the 29th of July 1822
WHERE yonder chalky cliff extends its side,
We from descending torrents sought to hide,
The treacherous pit o’erwhelming laid us low,
And life forc’d out by one tremendous blow.
At once from light, from friends, from kindred torn,
Our sorrowing parents o’er our ashes mourn.
O thou who treads’t this consecrated earth,
Let our sad fate to solemn thoughts give birth!
Then conscience ask should death this day await,
What, O my soul, would be thy future state!
