   Hi Keith,

   Thanks a lot for getting back to me.  This sounds really hopeful.  It would be great to
   crack this nut and marvellous to hear your working on it. I look forward to seeing the
   manuscript; do you mind if I share it with Richard Duncan and Jonathan Palmer who I am
   working closely with on this?  It won't go any further.

   I'll also check it's alright to send the data to you to run through the program.  I'm sure
   it won't be a problem but best check before hand.

   Hope things are going well.

   All the best,

   Chris

     Chris,
     We have written a paper recently for the book being edited by Malcolm Hughes and Henry
     Diaz. Tom will forward a copy - though please treat this as confidential until the final
     version is agreed - thanks.  It is true that the RCS can be biased by recent data (and
     produce a somewhat undefined trend in the overall chronology when this is produced from
     only living trees).  Take a particular look at the first example of problem applications
     -  near the end of the article (the "Briffa Bodge" bit!).
     How about looking at the data with the new RCS program we have?  The software is not
     quite ready for general use but it will not be long.  In the meantime Tom and I here
     could put your data through it to see what it looks like and you can have the software
     when he and I have agreed the final version of course.
     Best wishes,
     Keith and Tom.

     Dear Keith,

     Sorry to bother you but I was wondering whether I could pick your brain? I'm working
     with some friends in New Zealand, looking at quantifying past temperature change using
     pink pine. We have a robust dataset stretching back 550 years but using modern trees.
     Using the RCS method we are concerned we are losing the long-term temperature trend
     because of the bias introduced by the reliance on modern trees.

     We wondering whether you have any idea how best to overcome this issue? Any ideas would
     be fantastic. We've got a stunning dataset but feel frustrated we're missing out on a
     significant part of the story.

     Look forward to hearing your thoughts.

     Best wishes,

     Chris
