open me jar in farnham

on the weekend we went on a walk in farnham, on the way i found a very magical fairy arch, a sparkly tree, and a nice restaurant called the lion and the lamb. in  farnham at the end of waynflete lane there is a dirt path that will lead you to a river when you get to the river stop and go left, you will see a funny shaped route/tree with a hole in it. look in there...
