    Re: Simple celestial navigation in 1897

    As for evidence that people were still doing time sights and Noon Sun, I
    just wanted to remind everyone that people on this list did just that some
    decades ago. Here's a post from Henry Halboth detailing the procedure for
    combining the morning time sight with the noon latitude:

    (http://www.i-DEADLINK-com/lists/navigation/0506/0202.html)
    
    Of course (!), there is an equivalent procedure with two Sumner lines. The
    point is simply that celestial lines of position did not become the universal
    procedure until almost a hundred years after Sumner's booklet was published.
