    It is interesting and fun to read Surveying textbooks having 1 st edition dates 20 or 30 years apart. Early books , say 1890s to 1940s  spend a significant  amount of time determining true north, compass correction, etc. Knowing exact time was quite a chore. I’ll look, but at some point the telegraph system was used for time.  I’ve given away my oldest books so I can’t check them. These books often have detailed explanations of dip, refraction, etc
    Most early deeds, especially east of the Mississippi River using “metes & bounds” had bearings for direction of a  boundary line.  For example, .......starting at 24 inch Oak tree 40 paces from the NE corner of Smith’s barn, go 100 paces north 70 degrees west to a pile of rocks adjacent to the marsh, then go 140 paces S 60 E.......  These bearings are turned from north or south with a bearing not exceeding 90 degrees. Eventually they starting using “chains” for distances.
    There are many stories about boundary surveyors. Some are true.  Many, many years ago...say 50, I met a guy in his 80s or 90s, he had a drinking problem...maybe just liked to drink.....anyway he swore he helped to layout the boundary of  North Dakota or some other late arrival U.S. state. He swore they did a lot of surveying from their camp near town because the indians were still fighting with the railroads....

    Subject: [NavList] Celestial position-finding on land

    Hello all,

    Gary LaPook's reply to my question about his artillery sight remined me of an article I had read in The Field Artillery Journal, Nov. 1942 about Celestial Navigation for field artillery. It talks about finding the position of the unit (battery) when in the North African desert by Cel-Nav. Almost a short course on LOP's, HO 214, Almanac, etc.

    I have used Cel-Nav when flying in the Air Force and I gather most here use their sextant for boat navigation. My question: Has anyone used Cel-Nav for anthing else? I would think surveyors might have in the past and explorers.
