Last year I posted some questions about how Sumner discovered the celestial line of position, because the bits I had found to that point did not seem to tell the whole story. Gaps remain, but thanks to contributions from many on this list and elsewhere, I have been able to produce a modest illustrated tale: http://jimthompson.net/boating/CelestialNav/SumnerTrip.htm Additions and criticisms always welcome.
