Spot the ball competitions were popular in newspapers of the 1960s and 1970s but here's a twist - can you spot the site of The Valley on this plan of 1838 before the railway line was built and before the ballast/chalk pit created the quarry face utilised for the East Terrace?
The major road lines are largely unchanged which helps.

It looks pretty sure it is 106 plus 100.
I would reckon this to be the most likely combination.
What throws it a bit is the absence of the Railway line to provide a bit more context but No 106 is the entrance to the chalk pit which was later extended massively into the field marked 100 in order to extract chalk/sand? for ship's ballast and the quarry became known as the Great Ballast Pit or something similar.
The numbers correspond to the numbers on the Tithe (taxable land map) of 1838 which give 106 as an old chalk pit and 100 as a pasture field. I think the major quarrying which provided the site of The Valley took place after 1850.
Interesting article I have not seen.
