    | To pass the winter's day I frequently turn to novels concerning the British
    | navy in the late 1700's.  I came across passage where a small boat became
    | separated from the mother ship in a fog.  They in the boat had taken bearing
    | fore and aft  on the way out but had lost the compass in scuffle with the
    | French.  In the fog they had no idea of the direction back to the ship.  The
    | moon was barely visible above the fog.  They computed the way back
    | For any meridian the moon will cross just 49 minutes after the sun crosses
    | and the moon falls back 49 minutes every day.
    | By counting the days after new moon, multiplying that number by 49 and
    | dividing by 60
    | One arrives at the time in hours and minutes when the moon is due south.
    | With south noted and knowing the reciprocal bearing back the ship they could
    | safely return.
    | I haven' had time to check out the reasoning and math but I thought it would
    | be of interest  to the list.   The author also described lunars in an
    | earlier novel.  Quite interesting reading.
