I found this marvellous book from 1892 in the Westcountry Studies Library, now Devon Archives and Local Studies.
Yesterday, cycling down a section of Woodwater Lane, I noticed a corn cockle in the bank. It struck me that I have cycled down the lane many a time, walked down it occasionally, picked blackberries at that time of year, but I have never really paid attention to it.
