Hmm, the Times and the Post have different headline casing styles.

Meterstones, 2024

Small accomplishments during the year, not otherwise accounted for. Not major milestones, but bigger than inchstones.

  • I took on new responsibilities for Virginia Native Plant Society.
  • I resumed working in community theater, stage managing Dance Nation for Silver Spring Stage and Kindertransport (in rehearsal) for Rockville Little Theatre. Much waiting in traffic to cross the Cabin John bridge.
  • After trips to three different shops and a returned online order, I found the right replacement halogen bulb for my bedside lamp. After multiple trips to local stores, I bought a $7 (+ shipping) threaded rod from McMaster-Carr and successfully repaired a chair from IKEA (model long discontinued) that I’ve had since I moved into this house.

Postcards from Ohio: October 2024: Addendum

I stopped in Columbus at the Wexner Center for the Arts on my way west, and found numerous six-wheeled robots tootling around the OSU campus. A robot seemed to manage crossing a driveway (into a parking deck, for instance) just fine, but I had the uncanny feeling that it waited for me to start to cross, that being a signal that it was safe to move. The robot’s cargo bay was about the size of a backpack, but shaped more like a little bathtub.

What were these automata delivering? Library books, mayhaps? Nope, it’s food. It’s always food.

Forte

Linda Holmes nails it in her response to Apple’s crass iPad advertisement.

But these are not practical items to begin with. Nobody owns a piano because it’s practical; it’s about the least practical thing you can own. It can wreck your floor. It goes out of tune. And if you happen to get a new place, you don’t just need movers for it; you may need special movers. You don’t own a piano to get from point A to point B in the most direct way you can. You own a piano for the reason we had one in my house: a person plays it. Someone sits down, as my mother did, and plays the “Maple Leaf Rag,” and you can hear the pedals lightly squeak, and you can watch hands skitter across keys, and of course you are listening to music — but also, those are your mother’s hands.

In my case, the piano’s owner was Leta and the player was Grandmother Madeline.

And in my case, the piano was in the Northern Michigan University dormitory lounge and the player was Audrey from Rockford, Ill., and the song was indeed “Maple Leaf Rag.”

  • Walter Shawlee, slipstick reseller, has passed.

    Over time, his customers included a weather station in Antarctica, where many electronic gadgets could not take the cold; photo editors responsible for adjusting image sizes (they like slide rules for their clear displays of different values for the same ratio); an archaeologist who found that calculators got too dusty to work properly during digs; the drug company Pfizer, which gave away slide rules as gifts during a trade show; slide rule enthusiasts in Afghanistan and French Polynesia; and “guys from NASA,” Mr. Shawlee told Engineering Times in 2000.

  • Sorry, overwintering turtles don’t breathe through their butts.

    The notion that cloacal gas exchange helps North American turtles survive long winters trapped under the ice is pervasive in pop science, but to date, there is no solid evidence that hidden-necked turtles use cloacal gas exchange. The skin and mouth lining are where gas exchange happens during winter hibernation.

  • The Old English for spider is gange-wæfre (“walker-weaver”).
  • From Zack Stanton for McSweeney’s, “Morrissey or Trump?”

    This could only happen to me / Who has been through anything like this?

  • Guest column for Washington Business Journal by Alan Berube and Tracy Hadden Loh: “Caps and Wizards moving to Virginia isn’t ‘regionalism.’ It’s gaslighting.”

Mid-winter trip reports

I assisted at Elklick Woodlands Natural Area Preserve for a couple of work days. (More days to come? subject to scheduling.) Park Authority staff are actively managing woody vegetation within several deer exclosures in order to re-establish and extend a rare forest community, known as northern hardpan basic oak-hickory forest. Thousands of trees were planted about five years ago, and those that have survived are about knee height now.

to be trimmedThe management is fairly aggressive: both native and non-native trees, all of them faster growing than the oaks and hickories, are cut back to the ground, for instance these Virginia Pines (Pinus virginiana) which would soon shade out the white oak at the right of the photo.

oak saplingMany of the trees that we’re nurturing are still very small, and have dropped all their leaves at this time of the year. So flags make it a lot easier to find them.

I’m also back at The Nature Conservancy’s Fraser Preserve, now equipped with a new tool: an Extractigator Junior, generically known as a weed wrench. For non-native invasive shrubs like Rosa multiflora and Berberis thunbergii, we need to remove as much of the root as possible. A garden fork and some steady pulling will accomplish this, but a weed wrench gives you some mechanical advantage and is easier on the muscles. The genius of these gizmos is that no springs are involved, so it’s unlikely that you’re going to mash a digit.

I’m still finding my touch with the tool. With smaller plants, I have a tendency to snap off the stem rather than pull it out with the roots. The Junior weighs just under ten pounds, so it’s luggable from Fraser’s parking area to our work sites.
