    Story of Sumner's line invention
    From: Jim Thompson
    Date: 2004 Apr 1, 06:35 -0400

    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:

    Additions and criticisms always welcome.
