This tree is too old to tap, with signs of fungus and moss covering much of the trunk. Years of soil neglect have taken their toll.
It’s been a busy 16 months. I’ve had a baby girl, taught Introduction to Robotics at Mount Holyoke College, and continued to apply permaculture techniques to our land. Christine asked me the other day why my technology blog had veered so far into gardening before going quiet. I see the garden and all the living creatures in it as being intimately connected with technology – a showcase and a test bed. To wit:
This spring I tapped the row of maple trees on our property. By some accounts Native Americans got 17% of their calories from maple sugar, and I have been wanting to try my hand at it. This year I got a jump and ordered the taps and tubes in December, so that when the temperatures started climbing above freezing by day I would be ready.
My mother recently completed her chemotherapy and had her port removed. This was on my mind as I inserted ports, aka spiles, into my maple trees and began collecting fluid. I’ve gathered about 3 gallons of sap so far. The biggest surprise is how tasty it is when it’s only been boiled down about 25%. It has all sorts of subtle flavors beyond sweet that put me in mind of birch beer.
My test batch – a pint of sap yields a tablespoon of syrup.
Gonna need a bigger pot
The process of tapping also forced me to look closely at my trees. Most of them are quite robust and are putting out a good amount of sap, but two had enough signs of distress that I chose to pass them by. One is just getting on in years and being taken over by moss. The other has a narrow fork that looks like it is starting to rot out. Both of these trees had their roots exposed by decades of poor soil management, and will probably have to come down in the near(ish) future. Which is a topic for my next post…
In the meantime I’ll keep the sap boiling and continue to enjoy all the health benefits of locally-sourced, sustainably produced, small batch artisanal maple water and maple syrup.
Autumn is upon us, so I set about expanding the leaf weir with the summer’s tree cuttings. Weaving in the branches I had gathered raised the level of the weir by about a foot, and extended it several feet toward the sunflowers. Continue reading
Brick, American, 19th century
There’s a great post on Next Nature about brick sculpture by Maarten Vanden Eynde. Bricks are one of my favorite technologies for being incredibly long lived and durable. The basic form of fired brick has hardly changed in over 6,000 years! They are living proof that technologies don’t go extinct.
The landscape where we live is littered with bricks, the residue of our recent industrial past. They erode from hillsides and stream beds like fossils. A great many were spread along the Mill River by the Flood of 1874, forming a technological smear in the landscape that will persist for millennia. Still functional, the bones of old mills make their way into my garden terraces.
“All the armies that have marched the earth, and quenched its soil with their blood. These boys of our passing days, and all their comrades in arms who are dust. The hordes of Genghis Kahn, the legions of Assisi, the bowmen of Assyria, all the children of today, and of unnumbered yesterdays. All the poets, all the tyrants, all the philosophers, and all the fools. All of mankind who have lived and labored on this planet since the beginning, all have come from this microscopic egg, many many times smaller than a mustard seed.” –In the Beginning, 1937 (USDA Extension Service, Division of Motion Pictures)
A robin had its birthday somewhere above our garden, leaving behind this trace.
I found this robin’s egg nestled alongside a maple seed, each playing their role in an unbroken chain stretching back billions of years. It reminded me of In the Beginning (1937) which is preserved in the excellent Prelinger Archives. Don’t watch the linked movie unless you can stomach a bit of leporine vivisection.
While science has understood the mechanics of life in broad strokes for centuries, we are still grappling with the implications. Of all the different forms that life has given rise to on this planet, should we be so surprised that human technology is among them? Next to the intricate beauty of a seed or an egg, our tools are crude and simple beings.
