Classical Books on Farming/Prepping

[Tartar Horde]

Marcus Porcius Cato (Cato the Elder)
Roman Farm Management.

E-Book can be found at http://www.munseys.com

This is how the Romans did it folks, this excellent treatise explains how to run a Roman farm and covers everything!
In a post SHTF scenario there is a lot of information that can be used in this book, as it shows how to farm without any modern power sources.
Highly recomended ( in my humble opinion)

Fortuna favet menti paratae
