Yes I have read some about that it is very interesting. I would never have though of MALARIA being one of the biggest obstacles in acomplishing that canal.
I also have a book my brother loaned me about building HOOVER DAM that i have been reading.
If you get a chance read about building the Erie Canal. It was the first great Civil Engineering project in the United States. They had monstorous wheels and axles setup to pull stumps and many ingenius other animal pulled machines.
