Diagramming Sentences in the 19th Century

I loved diagramming sentences in grade school. I'm sure I did it in 6th grade, but possibly 5th grade as well. Over a Language Log Victor Mair has a post on the subject, Diagramming: history of the visualization of grammar in the 19th century, which links to a review article by Hunter Dukes that contains photographic copies of seven archival texts: American Grammar: Diagraming Sentences in the 19th Century. Mair's article has a number of interesting quotations from Dukes' text.
