In the late 80s I became curious about the different sounds I had heard in and
around crop circles.  I thought they might be emanating from the ground.  I
wondered how I could check this so I had the idea of putting two metal probes
into the ground and connecting them with leads to a jack plug which I inserted
into the microphone socket of a standard cassette tape recorder.  Depending
where I used the probes, the result was very interesting.  I began playing back
what I had recorded and was amazed at the different sounds of humming,
clicking, buzzing and a mixture of other sounds.

In my garden I have a large sturdy Blue Cedar tree and as it was well
connected to the ground I wondered if it carried any recordable sounds.  At
about one and a half metres up from the ground I inserted a probe through
the bark and into the live wood underneath and I pushed the other probe into
the ground about half a metre out from the trunk and recorded.  The result
was staggering – I was listening to a musical trilling sound.

Since that day I have recorded the same sound from various trees ranging
over a very wide area.  Despite enquiries, I have no answer as to how these
trilling sounds are generated.

The report on Colin Andrews website regarding the trilling sound we
encountered at the Cheesefoot Head crop circle generated much interest.  
Through a fellow researcher, Miles Johnston, I contacted Win Keech who has
filmed what strongly appears to be the formation of crop circles.  I mentioned
the trilling sound to him that I had recorded and the similarity between this and
the crop circle trilling.  He was intrigued when I played a sample of the tree
trilling over the phone.  I explained the probe recording procedure and he said
he would try it.  It was such a success that he sent me a copy of his initial
results having used his professional equipment.  This compares very
favourably with the crop circle trilling.  They are almost identical. 'This is the
only conclusion reached so far and the source remains unknown'.
His report follows.
