Monkey's Marginalia No 15

1.  Unpopular Ford models & the McKay's review

Edsel B. Grimshaw is a direct reference to 3 (or 4) unpopular Ford Models.

• Ford Edsel-models falling under the Edsel marque (1958-1960)
• Ford Model B (1904-1906, 1932-34)
• Ford Pinto (1971-1980) The reference to the Pinto comes from Grimshaw v. Ford Motor Co.

The Ford Motor Co. was obviously established by Henry Ford, who used the assembly lines and fair wages for his own employees to make the automobile affordable for the middle class.  He also used most of his vast personal wealth to create the Ford Foundation.  As with several historical figures, sometimes their works are a mixed bag; Ford was also known for his anti-union activities, and as the author of some anti-semitic pamphlets. 

Also of note is the Mercury(!) brand or marque sold under the Ford Motor Co. umbrella.  The Pinto was sold as the rebadged Mercury Bobcat in Canada and the U.S. 

2.  Possible design for the obsidian pieces? 

3.  Arquimedes des Sobreiro is a corkscrew...

The Greek Archimedes invented a form of water pump called the Archimedes screw.  Sobreiro means cork tree.   Playing around with the words a little, I got corkscrew and water tree (a plant found in Australia). 

4.  The first two words (not titles) of the last 4 sections of the book rearrange to say "there is a man shrouded in the territory."
