^{by Lewis Howard Latimer in 1890}

electricity, like air around us, seems impalpable, appeals
to so few senses. but it is capable of being measured,

because my husband leaves lights on throughout the house
as though placing bookmarks. at night, I waltz across rooms

and unmark his pages, twist knobs on lamps’ necks,
flick switches, power us down. this sounds like a complaint,

but it’s how we communicate: he opens the curtains, I close them
minutes later. he puts the dogs out for breeze and sun, I call them

back. I whistle, he picks up the tune, so I relinquish the song. discovery
of the familiar: the language of electricity, the incandescent patent filed

first, fine pen, labeled parts, application slapped on a desk for permission
to write the first chapter. every once and a while, I look up in this house,

and I find there’s not the right light, so I buy fixtures and he installs them:
cuts power, wraps black tape, twists wires until his arms are sore. I take

the victory and twist new bulbs for their first glow. as for the old?
each time, I shake them for the filmament’s soft bell. we happily

confine ourselves to this age of light. we understand the parts, the actions
upon each other—but without entering too deeply into their intricacies.
