Query: This "science" is a bad joke

I decided to to a study of tree rings when I read how they supposedly matched up the tree rings from some 8000 year old tree to some dead older tree to extend the timeline to 12,000 years. Well, I examined the tree rings of six trees, all cut down the same year in the same park and all dead from Dutch Elm Disease. I saw NO correlation between the rings.So, I did the same thing at Lake Tahoe. Still, no correlation.So, no, I didn't WASTE my money on this book.
