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_ (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. -FER 42.0N 87.7W, or 41.4N 72.1W. www.HistoricalAtlas.com/lunars
