Great find, William! @43 he talks about the North American giants, some 10 feet tall! Even Abraham Lincoln spoke about them openly "a former race of giants gazing out at Niagra Falls..."!
You don't hear about the North American Giants as much (especially in New England where they like to keep their famed histories straight...the colonists and the disorganized tribes before them. The tribes reported another race before them. I wonder what wiped them out? The gravitational forces strengthened and made it harder to maintain a tall structure?
