Looks like a neat book. Build Your Own Earth Oven is a simple, fully-illustrated handbook for making a wood-fired, masonry-style oven out of inexpensive earthen materials (similar to adobe and cob). The book provides clear, step-by-step instructions for building and firing the oven, as well as complete directions for making sourdough bread in the best (and simplest) artisan tradition. Link.
Mother Earth News has complete instructions on their website:

Enjoy!

That Mother Earth News lionk is great, but Holy Cow, I have never read anything with so many typos!
You know, the book is actually chock full of pretty good details. If you want to tackle the project, be sure to get the third edition. It is much enhanced over the first and contains some of the bits that I found to be vital!
