When I read old books, I’m always on the lookout for
references to other old books, or to topics that were relevant when the book was
written, but that may not be well known now.
These sometimes lead in new and surprising directions. There were several things in Bolton Hall’s Three Acres and Liberty, the book that
launched the back-to-the-land movement in 1907, that seemed to deserve more
investigation. The thing that really
jumped out at me, though, was a passing remark he made about blueberries.
In spite of being a hardy native plant that the Indians had
harvested from time immemorial, Hall says “with our present knowledge of the
blueberry, it is doubtful if it can be made a commercially cultivated
crop.” This surprised me, since one of
my family’s favorite activities when we lived out East was picking blueberries
at a big berry farm in the shadow of Mount Monadnock. But Bolton Hall was no dummy. Three
Acres and Liberty describes a variety of intensive gardening techniques
that are popular today (and that many people think were invented by their
current proponents), including the use of manure instead of commercial
fertilizers; “super close culture,” where plants are set very close together to
use the land and water efficiently and keep down weeds; “companion cropping”
and “double cropping,” to extend the growing season; rotation to reduce the
impact of pests; soil inoculation using nitrogen-fixing legumes (just recently
discovered when he wrote); mulching to save water; raising chickens, ducks and
rabbits to use waste and produce food and manure; canning and drying to
preserve even small quantities of food; and even disposal of city sewage by
using human waste on urban gardens. So I
had to believe he was right about blueberries not being commercially viable in
1907. And of course, the obvious next
question was, when did this change?
