This book is chock full of hand drawn charts and graphs and information about building a farm from the earth up (aka homesteading). It incorporates lots of ideas that, if you were to actually follow through with them (all the building plans are for circular buildings) might make you look like a real nut job, but where else are you going to find directions for a fish garden with scientific reasoning for incorporating three circular ponds? A good read if you're interested in agriculture and in alternative environmental design.
