This cache is part of a series of seven caches placed at or near wells in the Chilterns. On the logsheet (of six of the seven caches), you will find a number - eg A=1, B=2 - which you can use to get the co-ordinates of a bonus cache.
If you want to do the series as a circuit, you may want to do them in roughly numerical order - starting at Binfield Heath, then Rotherfield Peppard, Gallowstree Common, Kidmore End, Ipsden, Stoke Row, Highmoor and then the bonus...
Some geology/history... Chalk is a very porous rock so a high percentage of rainwater just seeps through the cracks and fissures in the chalk down to the water table, rather than collecting in streams and rivers. In previous centuries, villages up in the Chilterns often suffered from severe water shortages and relied on wells for their water supply - many communities didn't get piped water until the mid-1900s. Maharajah's Well in Stoke Row is almost certainly the best known well in the area, but there are many more, both beside roads and also in people's back gardens.
Kidmore End The well at Kidmore End is in the middle of a T-junction - it's quite surprising that it has survived! Like the well at Gallowstree Common, it's a listed building. It dates from the late 19th century. Take a bit of time to have a look at it - and to grab the cache there, of course!
As there is already another cache at the well, this cache is placed a few minutes walk away. The cache can be found at N51 30.ABC W000 59.DEF
Park your car/bike at the well (N51 30.535 W000 59.720). Look at the signpost. Add the number of miles to Tokers Green and to Mapledurham. This is A.
Walk along the road, with the church on your right, and stop next to the war memorial. In front of you, you will see a white number in a red square. This is B.
The church noticeboard is a few steps further on. How many letters are there in the last word on the sign? This is C.
Turn around. Next to the village pond is a green GPO box with a white number on it. This is D.
Now carry on walking along the road, past the pub. When you reach Coopers Pightle, look at the telegraph pole opposite and you will find DP FE (in that order).
It's now a very short walk to the cache. You are looking for a 35mm film container. Please replace exactly as found.
