National Geographic's September 2009 striking reconstruction of "Mannahatta" -- what New York City looked like when Henry Hudson ventured by in 1609 -- has been all over the magazine stands recently. Which reminds me that the authoritative book on Henry Hudson on the 400th anniversary of his tour up the river now named for him is from Canadian writer (and, blush, friend of this blog) Douglas Hunter. Half Moon is published this month.
