I'm a bit confused here. When I suggested constructing a Mercator sheet
for a specific area, I did not mean from a UPS. I was referring to
keeping longitude lines equally spaced, and using Bowditch Table 6 (was
Table 5?) Meridional Parts to arrive at the spacing of the parallels.

My reference is "Practical Celestial Navigation," by Susan P. Howell,
6rh printing, 2003, published by Mystic Seaport.  If memory serves, Mrs.
Howell was colleague of yours at Mystic Seaport who lost her life when a
training ship, Marques, went down near Bermuda.

If there is a question in there, is her method a "bad habit?"

I am guessing scanning the relevant pages and posting on NavList would
be copyright infringement. As a creator with Library of Congress
registered copyrights, I am like you, especially prickly on that
subject. If I scanned the pages and sent them to Samuel off list, would
that qualify for the "limited copies for instructional use" loophole?

Thanks

PS Along with lofty title of "Head cartographer, Centennia Historical
Atlas, HistoricalAtlas.com" do you also hold the title of "Garbage and
Trash Removal" shared by many other small business owners? Or did you
write that out of your job description when you were writing it? ;-)
