+1 vote for Kourik's book. I'm just reading it now. Permaculture isn't mentioned much, but that's what it is. Of course, I think the word was trademarked or something back then.
The book also encourages a lively sense of experimentation and observation in the garden and farm. In addition, she gives good advice on obtaining germplasm, with lists of sources for both annual and perennial crops, and advice on obtaining stock from the USDA Germplasm system, which in my opinion is a vastly overlooked source (no doubt because people are astonished that the USDA actually does something useful). On top of all it's other virtues, this book is a good seed saving reference. It now occupies a place of honor on my shelf next to Seed to Seed.
The latter is likewise fascinating but I was a bit depressed to see someone writing in 1908 on the foolishness of westerners refusing to utilize humanure and realizing that nothing has changed on that front in 100 years.
We tried this for the first time last summer, and I think the spacing advice I got from some website (not this one, not a forum) put the corn way too far apart for good pollination. We were instructed to wait to plant the beans and squash until the corn was a few inches high. I sowed buckwheat around in the whole patch right away, and I was glad for this decision because the later planted squash took until late july to fill in.

The first whites had to paddle around in canoes to stake their claims. We drove around Wasco/Bakersfield recently visiting family....all I could do was imagine huge flocks of birds feasting among grasses and reeds, elk carefully wading through the water....I really wish I had a time machine sometimes.
