Dear Don,

My oral exam is scheduled for May  19, so by definition I now have  a
first  draft of  my  thesis  ready. Actually,  a  few appendices  are
missing and the overview chapter is only half written.


I'm  sending you this draft  now, in case you'd like  to look it over.
I hope the delay hasn't dulled your interest.

Your memory of  my talk will probably suffice to  fill in the missing
oveview material.   Chapter 2 contains  an introductory example.  The
next few chapters deal with the  control structure and representation
in  great  detail.   The last  couple  chapters present  some  of the
results and conclusions.

If you think of a better title, I'm still open for suggestions.   The
subtitle is of course a joke, and will change before the final draft.

If you return  this draft  with some
suggestions,  I'll mail you another  copy right away.   In any event,
I'll send you a copy of the final thesis.

My wife Merle and I will be visiting CMU next month (June 1-4), and 
I hope we can get together then.

.DBL(Regards, Doug Lenat)
