Del, you need to remember that Lawrence of Arabia lost the entire first draft of `Seven Pillars of Wisdom' when he left it at Reading Station.   Compared to that literary tragedy, 15 chapters of `Great Achievements of the Welsh Nation' is hardly a loss -- just look at it as one less book to stick in the already overstocked `Fantasy' section of Barnes and Noble.  Every cloud has a silver lining.  Bonjour tristesse, no less.
