    Brad, regarding the mysterious entry "N36E 52 41" on the 4th of May, I have got an idea:

    obs'd psn 3rd   56°13'S          45°38'W
    obs'd psn 4th   55  31             44  43
                             ----------          -----------
                         dlat    42'N    dlong   55'E

    mean lat  55°52'

    lat     dep for 55' dlong
    55     31.5
    56     30.8
            -------
               0.7

    Mental interpolation gives a departure of 31 for the mean lat. By inspection in the traverse table we find the course N36°E and distance 52 miles. The day's run.

    So maybe the entry shall be "N36E 52 42", or, still better, "N36E 52 42 55 = 31".

    Lars
