Stony Man to Jewel Hollow
Stephanie Mason led another nature hike yesterday, this time at an elevation considerably higher than three weeks ago. We covered about 5 miles along the Appalachian Trail and side trails, from Stony Man to Jewel Hollow.
We got some nice looks at high-elevation tree specialists for our region, like Balsam Fir (Abies balsamea), Red Spruce (Picea rubens), and the glossy-barked Yellow Birch (Betula alleghaniensis). Perhaps owing to the higher elevations around Stony Man (4011 feet), the Eastern Hemlock (Tsuga canadensis) trees in this patch look pretty healthy and untouched by the adelgids.
Closer to the ground, spring ephemerals were abundant—Wild Pink, Moss Phlox, cinquefoil, bluets, many violets, Wood Anemone, waterleaf, Star Chickweed. I picked up one butterfly for my list, Falcate Orangetip (Anthocharis midea). Among the birds, the best was a bird from my “renewal” list of lifers that I haven’t seen in a long time: Veery (Catharus fuscescens). Good, multiple looks at Chestnut-sided Warbler (and we could point them out to a party of passing hikers) and American Redstart.
We climbed about 300 feet, then dropped down and ended about 300 feet below our starting point. We hit Stony Man early enough in the day (before noon) that the traffic was not too bad.

Textbook pastebin
When I’m recording a textbook at Learning Ally, I often find it necessary to scribble a sentence fragment from the top or bottom of a page onto a scratchpad, so that I can read the complete sentence smoothly without a noisy rustle of turning pages. I recently worked on Theodore J. Lowi et al., American Government: Power and Purpose (2012), 12/e. In an exercise in political science found art (or spammy nonsense, you may decide), I collected all my scribbles from various page turns in the book, and here they are:

2 solos
Two powerful solo shows played in the area over the past weekend, both of them responses to violence: in one case, large-scale mayhem that many of us would consider heroic; in the other, a small-group killing, inexplicable, that has deep emotional resonance.
Denis O’Hare is The Poet, a time-shifting tramp in a trenchcoat and porkpie hat (rather than one of Samuel Beckett’s bowlers), tumbled down the centuries to sing the story of Homer’s Iliad. The Poet’s song/riff is a blend of the original Greek, a verse translation, a bit of audience interaction and prompting, and a free adaptation into vernacular English. His memory failing, nevertheless the Poet can summon music and his Muses (skillful Brian Ellingsen on double bass and Milltone tongue piano) and can turn a clever phrase: “Athena tequila” is especially fun.
The piece focuses on the best-known incidents of Homer’s poem: the love between Achilles and Patroclus, Achilles’ great sulk, and the brutal killings of Patroclus and Hector. The Poet’s sentiments perhaps lie with the people of Troy, for although O’Hare’s voice is neutral when he embodies one of the Trojans, he adopts a loutish English dialect for the Greeks that owes something to Sicily or South Philly. The crux of this 100-minute monologue is a stupendous catalogue of wars known to Western history, for a thousand years an unbroken chain ending (for now) in Syria.
Speaking to us out of time as he does, when the Poet names the great cities destroyed by war, from Troy down to Dresden and Hiroshima, he briefly pauses, then moves on. Could it be that, Cassandra-like, he can see the next great devastation of the future, and knows (better than the Greek prophetess did) that it is pointless to share his vision with us?
Nanna Ingvarsson’s task is no less challenging, as she personifies more than half a dozen people (many of them composites) connected to the 2006 mass murder-suicide at the West Nickel Mines School, a former Amish one-room schoolhouse in Lancaster County, Pennsylvania. From an innocent schoolgirl of six or seven, to a sassy supermarket clerk, to the tormented killer himself, Ingvarsson runs through a series of emotional and physical changes; Jessica Dickey’s script is a patchwork quilt of interlayered monologues (with a small debt to the Tectonic Theater Project’s own Laramie Project). The actor does well to focus on a specific, simple gesture for each speaker (a twirled bonnet string, a closed-off pair of folded arms) so that we keep our bearings as characters pop in and out.
The piece works best as a primer on the Amish perspective on the shootings. Rather than seek an explanation, a “why” of the violence, the community’s immediate response is one of of compassion, most notably toward the widow of the gunman. We hear the inspiring story of martyred Anabaptist Dirk Willemsz, who escaped from religious imprisonment across thin ice, only to turn back to rescue his pursuer who had broken through into the icy water. Is it possible that such a simple gesture of peace can forestall destruction?

Silver Line progress report: 36
Martin Di Caro briefs us on the outstanding reliability problems to be resolved before Phase 1 of the Silver Line can be opened. Safety is not at issue; rather, the signaling, communication, and control system glitches can lead to trains automatically stopping, requiring the operator to ask operations for an OK to proceed.
Rail safety experts say the Silver Line’s problems, while frustrating for the public, are not unusual in the world of railroad engineering.
“It happens any time new technology is employed with old technology, and it requires the testing of the system on paper and in design,” said Steve Sullivan, a managing director at R.L. Banks and Associates, an Arlington-based rail design and operations consulting firm, referring to the linking of the Silver to Orange Lines.
Spring at Calvert Cliffs
Frogging by ear tips, derived from yesterday’s walk to Calvert Cliffs on the Western Shore of Chesapeake Bay with Stephanie Mason: Gray Tree Frog (Hyla versicolor and H. chrysoscelis) sounds something like the ratchet on a retractable dog leash, while the irregular clicking sound of Cricket Frog (Acris sp.) resembles those annoying magnetic balls that my colleague Dylan likes to play with.
Once again, we saw elvers shimmying their way up Grays Creek. Eels (the young are elvers) are catadromous, that is they migrate downstream from fresh to salt water to breed then die, unlike the better known anadromous migrants (like salmon) that swim upstream to freshwater spawning grounds.
Also in the watercourse, we saw many Water Boatmen (Corixidae) sculling about.
Stephanie calls the 5-inch-long Fence Lizard (Sceloporus undulatus) our local iguana, since it is in the same superfamily as the big guys of the southwest.
Trees were late leafing out (this is one of my favorite local species, Carpinus caroliniana, just opening up), so the birding was good. We heard or saw nearly three dozen species, and found two nests being built by Blue-gray Gnatcatchers (Polioptila caeruluea). The gnatcatchers showed some variety in vocalizations; one colloquy between two birds sounded like a couple of mockingbirds after too much espresso. My good bird was a fairly common species that I just don’t see very often, Yellow-throated Warbler (Dendroica dominica).
Towards an end to the killing
A leader from The Economist, noting the close vote in New Hampshire on renouncing capital punishment, and some surprisingly stern words arguing for its hasty demise.
…in a secular democracy a law of such gravity must have some compelling rational justification, which the death penalty does not.
* * *
…New Mexico, Oregon, Illinois, Connecticut, Maryland, Colorado and Washington stopped or suspended it. New Hampshire will try again. State by state, abolitionists will prevail. America is a nation founded on the principle that governments should not be trusted with too much power; that should include the power to strap people to a gurney and poison them.
Two Trains Running
Timothy Douglas’s cast brings home a strong, balanced production of August Wilson’s play set in 1969 Pittsburgh. Tony Cisek’s generously-proportioned set design, a rundown restaurant where the overhead fixtures haven’t been cleaned in a long time, gives the characters the opportunity to step forward to tell a story or to recede into the background as needed. There’s a rich texture to the lives of these people, as they go about their days, refilling salt shakers, playing solitaire dominoes to pass the time, or just eating a much-needed meal of beans and corn muffins.
Shannon Dorsey’s gimlet-eyed Risa rejects the appeals of the men around her, even as she knows she will end up tied to the charismatic Sterling (Ricardo Frederick Evans), a would-be revolutionary destined to serve petty sentences for petty crimes. Frank Britton gives comic relief Hambone a gravel voice and a ruined dignity. A great scene in a corner booth between the cranky old man Holloway (lanky Michael Anthony Williams with an expressive wingspan) and the louche numbers runner Wolf (stocky, stylin’ KenYatta Rogers in a red hat) crackles with energy.

- A team at Towson University has launched a microsite and apps (for Android and iOS) for tracking the spread of the highly invasive Wavy-leaf Basketgrass (Oplismenus hirtellus ssp. undulatifolius).
- Janet Fang summarizes a paper by Railsback and Johnson: simulations of coffee plantation activity indicate that 5% land coverage in trees maximizes coffee yields. The overstory of trees reduces the amount of space for coffee shrubs, but it invites birds, who forage on destructive borer beetles.
- Nancy L. Brill describes the survey that a team of entomologists made of invertebrate life in 50 ordinary Raleigh, N.C. homes. The typical house was host to 100 different species of arthropod.
Several families were found in more than 90 percent of homes: gall midges (Cecidomyiidae), ants (Formicidae) and carpet beetles (Dermestidae), along with cobweb spiders (Theridiidae), dark-winged fungus gnats (Sciaridae), cellar spiders (Pholcidae), scuttle flies (Phoridae) and book lice (Liposcelididae). Most houses also had dust mites (Pyroglyphidae).

When clashes occur, it is all too easy to fall back on reductive notions about liberal, elite environmentalists and conservative, redneck hunters—the “greens” versus “the hook-and-bullet crowd.” With partisans on both sides invoking stereotypes and the media portraying hunters and environmentalists as opponents, it is tempting to imagine stark lines between the two.
But such divisions are too simplistic.

As natural history has been de-emphasized, molecular biology, genetics, experimental biology and ecological modelling have flourished. But here is the problem: many of those fields ultimately rely on data and specimens from natural history….
No biology student should get a diploma without at least a single course in identifying organisms and learning basic techniques for observing and recording data about them.

Sleeping Beauty: A Puppet Ballet
An efficiently-told 57-minute version of the Tchaikovsky ballet, executed with a sort of “street puppetry” aesthetic in the confines of Flashpoint’s Mead Theatre Lab. The puppets Aurora, her suitor Florimund, the king and queen, and the two key fairies of the story are manipulated bunraku-style; the cast of eight doubles as live actors who fill in the roles of courtiers and the like.
If Aurora finds more than one pirouette to be a challenge, she does show remarkable hang time on her jumps. The transformation of the evil fairy Carabosse (she looks like a furry insect) into a dragon is quite fearsome.
The piece makes a good introduction to non-verbal storytelling for younger audiences; there were a few rapt youngsters with us on Saturday afternoon. A comic pair of courtiers break up the action with mischief and remind us that needles of any kind are not permitted in Princess Aurora’s home.
Arrive early to secure a front-row seat for the little ones; sight lines in this tiny black box are a challenge.

O rocks
In Provo Canyon, Utah, Scott Carrier gives a master class in writing to a young Afghan:
“Look down at the river,” I said. “Do you see any places where you could jump from rock to rock and make it across to the other side?”
“No,” he said, “there is too much water.”
“Well, imagine there is a place like that. I want you to think about writing as jumping from rock to rock. Can you swim?”
“Not very well.”
“Good. If you fall, you’ll drown. In order to jump to a rock you must answer my question honestly in your own voice, not the voice of someone else. If you try to answer in someone else’s voice, you’ll fall into the river and drown.”

Arguendo
A brief introduction to Elevator Repair Service’s aesthetic: performance of a found text, in this instance oral arguments before the Supreme Court in the case of Barnes v. Glen Theatre Inc. The case was argued in 1991, and concerned an Indiana statute that regulated go-go dancers in nightclubs and the like: a dancer was required to wear pasties and a g-string. Two South Bend clubs and three of their dancers brought suit, claiming the right to perform completely nude, citing First Amendment protections.
Whether you stand with the State or with the nightclubs on this issue, either before seeing this performance or after, hardly matters. The first two-thirds of the play is a whirlwind of citations and closely reasoned legal points, beyond the ken of a layman. It is precisely executed, retaining every harrumph, um, and disfluency (a lawyer’s fumbled “communicamating” is a happy accident). Ben Williams, in a distinctly unflattering wig, makes us sympathetic for the nerdy prosecutor from Indiana, Mr. Uhl.
Gradually, the play leaves realistic portrayal behind, commencing with a ballet for rolling desk chairs and culminating in a fantastical, graphic display (one could call it gratuitous, but what does that mean, in this context?). The battling lawyers do raise an interesting ontological question, certainly underscored by ERS’s performance: what is the difference between a depiction of conduct and the live performance of that conduct?
The justices display razor-sharp imagination: one of them speculates about an “adults-only car wash.” Justice Antonin Scalia gets off some of the best one-liners, among them a reference to the “Good Taste Clause” of the Constitution.

Zero Cost House
What kind of play is this? Well, it’s a good one, yet one that’s difficult to capture in complete sentences. My notes mostly consist of single words or phrases, among them “quiet,” “rich with time,” “waving back and forth,” and “arrogant? elegant?” But we can describe it as an autobiographical attempt by the writer Toshiki Okada to engage in a dialogue with his own younger self by 15 years, as he braids together his response to Thoreau’s Walden, the survivalist visions of the Japanese architect Kyohei Sakaguchi in the wake of the Fukushima disaster, and Björk’s second album, Post.
The ensemble of five takes turns portraying the playwright himself (as well as a cranky Thoreau and a loosely-screwed-down Sakaguchi), but it is Dito van Reigersberg who perhaps best catches the essence of Okada as a diffident, Japanese Bob Newhart (simile thanks to OTC). With a gesture that suggests either the scrawl from Tristram Shandy or the last flight of Challenger, van Reigersberg indicates the “trajectory” of Okada’s career. Rachel Christopher spends a good chunk of her stage time simply reading Walden and taking notes, but her expressive eyes tell an eloquent story nonetheless. Ephemeral.
