Gutenberg Gem: Rough Stone Monuments and Their Builders

StonehengeToday’s Gutenberg Gem is just something that interested me vaguely: Rough Stone Monuments and Their Builders. To be honest, I haven’t spent much time reading it, after all, you’d expect that we would know significantly more about this than those people publishing in 1912, but it does have some nice pictures and diagrams of rock burial mounds from the world over, including, of course Stonehenge.
