A wonderful compililation of letters from an infantryman in an Iowa regiment. Sgt Clayton was involved in actions in Missouri, Louisiana, and Alabama, including a stint as a confederate prisoner. Narrative anb pictures by Dr. Elder really rounded this book out. Clayton was an excellent writer and gives incredible insight into army life and the fighting of the civil war. Best of all you get a flavor for the general perceptions of the common soldier, the ones charged with the dirty work.

I thoroughly enjoyed this highly readable book, in fact resented any interruptions while trying to read it. Thank you, Dr. Elder!!

For those who want to understand the difference between global warming (which many believe is human induced) and climate change (which is natural and always occurring), Geological Perspectives is a MUST READ. While many would state the book is anti-green biased because it is produced by the American Association of Petroleum Geologists, it references literally 1000's of refereed scientific journal published papers that begin to reveal that this subject is a lot more uncertain than the IPCC claims.

While written for the general public, some sections require a background in the physical sciences to fully appreciate the book's content.

Yes, it is hard to believe that for the past 6000 years, the earth has actually been cooling (near it's coldest during geological time). However, humans have benefitted recently when temperatures have been on average warmer than colder. Don't under estimates the earth's ability to adjust to climate change!
