Yes AA, I have a copy of Hard Times Handbook by australians K & I Smith, kept in in our emergency box in case of disasters (earthquakes, flooding, volcanic eruptions are all possiblities living here) . Not a military one but full of all sorts of depression era survival skills & budget saving ideas!
We have lots of gardening & cooking/preserving books in our library, an accumulation of 30+ years of progressive learning, eg. from my trad home garden books from the 60's to John Jeavons then Mel Bartholomews Square Foot Gardening & just now I have out all the permaculture books from our 2 local city's libraries!
So I am enjoying reading the Gaia's Garden too. Plus find these other 2 books a great help with my current campaign to learn more about soil & how to improve mine here.
Building Soil, a down-to-earth approach. Elizabeth Murphy
I found this an excellent introduction & v practical.
Teaming with Microbes, the organic gardener's guide to the soil food web - J Lowefels & W Lewis - these authors are great advocates for adding compost & worm tea etc as their being biologically active materials, in contrast to Gaia's Toby Hemenway who is keener on sheet mulching...I'm working on all fronts here so combining the ideas from all 3 books!
