I heartily recommend a little book by that self-sufficiency guru John Seymour called Bring Me My Bow. You can pick up a second-hand copy on Amazon for a couple of quid. He blows all Teribus's guff about modern efficiencies and his defence of landlords clean out of the water. And John was no leftie. In fact, I find some of his rather right-wing views to be slightly obnoxious. That's just in case Teribus thinks I'm advocating this as part of some Marxist agenda. He has some very interesting things to say about modern agriculture in particular (he was a farmer for most of his life) and the economy of scale.
