This multi-cache will lead you on a short journey through some interesting parts of historical Walkerville. Take your time at stage two. There is a lot of interesting history here. See if you can find Matthew Flinders' niece and the police memorial. The final location is a source of great joy for all ages. I hope you enjoy the full resources of the park, including the rocker.
1. Blessed Stone. The first part of the cache is an intriguing locality. I drive past this church occasionally and wonder about people in high places. 
At this location you need to gather some information from the blessed stone to complete the co-ordinates of site two.
First check the date xx/x/xabc.
Use the numbers to work out the south co-ordinate.

Next complete following tasks.
A= Number of letters in fourth word of first line?
B= Number of letters in third word of fourth line?
C= Number of letters in third word of second line?
Use the numbers to work out the east co-ordinate.

2. Secret Society. In loving memory of whom, what and where? 
At this location you need to gather some information from the memorial stone with limited information to complete the co-ordinates.
G= C.S. - xxGx
H= H.H. - xxHx
I= K.E. - xxIx
J= J.B.S - xxJx
K= C.S. - xxxK
L= C.E. - xxxL
Use these numbers to work out the south and east co-ordinates of site three in a well known playground.
