Thank you.

Right. N by E (200), I see that now, and halfway to NNE
(400) from there is NNE 1/2 N (300) because it is an odd
hundred mil number. You mean I got the others right? :-)
But would not 600 mils be NE by N since 800 mils is NE?

So Hitchcock's "North by North West" is a valid designation
of the direction ... (looking for some paper) ... 5800 mils?
Or perhaps 326-1/4 degrees?

Thank you. I thought I learned to box the compass up to 32
points a great many years ago, but I didn't remember the
half points except as a term in sailing. Even the 32 were
obviously blurred in my memory.

Umm... Where could I find something that explained the
lunar system?
There was a brief time period during the French Revolution
that used a 10 (long) hour day of 100 (long) minutes per
hour, and ... 100 (short) seconds per minute? Was one of
the units called a lunar? I had a reference one time, but
it seems to be gone. Checking the web, I discover there is
the one time zone, X time, based on dividing the day into
100,000 as the unit, and starting the day at midnight (zero)
on the international date line. Seems similar.
