Thoreau’s Rivers
In the center of the town of Concord, Massachusetts, the Concord River is born where the Assabet and Sudbury Rivers come together at Egg Rock.
From here, the placid river flows past Emerson’s Old Manse and under the stone bridge that he immortalized as “the rude bridge that arched the flood,” a stone’s throw from the famous Minuteman statue by Daniel Chester French. (The photo is by Mark Wilson, from the Boston Globe.)
Published in 1982, A Conscious Stillness: Two Naturalists on Thoreau’s Rivers describes a series of journeys by canoe and foot down the two rivers that create the Concord. The book’s two authors are Ann Zwinger, author of earlier books on rivers, and Edwin Way Teale, a Pulitzer Prize winner and the author of more than thirty books on the natural world. Teale died before the book was completed, and it was left to Zwinger, along with Teale’s widow and others, to finish the job.
Teale was a meticulous note taker and a careful writer, so the task was not as hard as it might have been. Zwinger ekes out Teale’s finished prose with bracketed sections taken from his notes, and the notes are often hardly distinguishable from the finished product, though more likely to be written in the present tense.
Zwinger herself favors the present tense (as she discusses in the introduction) and although her writing is more effusive than Teale’s, she knows her river history and sometimes flashes out a twenty-dollar word: the “rataplan of rain” on a chilly March canoe trip, and tree branches “woven together like tiercerons” on a summer’s day.
Zwinger and Teale quote Thoreau less than I would have expected. (For Thoreau on rivers and meadows, see Henry David Thoreau: An American Landscape.) One reason may be that the two authors cover more of Thoreau’s rivers than Thoreau did himself, launching their canoes at the source of the gentle Sudbury and the rockier, more turbulent Assabet and following them wherever they lead, along flowery banks, under highway overpasses, and past the outlets of sewage treatment plants.
They do commemorate the day Thoreau and a companion reached the Framingham Ox-Bow, a landmark on the Assabet.
He and his friend Ellery Channing had started upstream that day rowing Thoreau’s homemade dory, and intending to go all the way to Saxonville. It was one of the sultry dog days of summer and along the way they refreshed themselves as best they could by dipping up the warm and muddy-tasting river water in a clamshell they carried in the boat. Buttonbushes had reached the height of their blooming and swarmed with honeybees. They noticed that they could hear the humming of the insects as much as six or seven rods away.
When they came to the Ox-Bow, Thoreau paced off the distance across the solid neck. He found it was almost exactly a hundred yards. He and Channing gazed up the river from the other side. Then they turned back. This point, sixteen miles upstream from Egg Rock, was the farthest Thoreau ever ascended either the Sudbury or the Assabet.
If I didn’t learn much that was new about Thoreau from this book, I did learn more about Concord and its surrounding towns. Here is Horace Hosmer’s recollection of the mill that produced paper (and polluted the Assabet) in the 1850s.
After the Crimean War 5 tons of soldiers white shirts came to this mill at one time just as they were taken off the dead bodies, matted with blood, and were made into writing paper. I weighed one of my shirts and it weighed ¾ of a pound, so there must have been the blood of 1000 men coloring the waters of our beautiful river. I sometimes thought the cardinal flowers, and the Maple leaves in Autumn were tinged with it.
Perhaps something of this was in Thoreau’s mind on August 20, 1851, when he wrote this about the cardinal flowers.
In the dry ditch, near Abel Minott’s house that was, I see cardinal-flowers, with their red artillery, reminding me of soldiers, — red men, war, and bloodshed. Some are four and a half feet high. Thy sins shall be as scarlet. Is it my sins that I see?
I had gotten the impression somewhere that Walter Harding’s biography The Days of Henry Thoreau was a kind of insanely detailed chronology, providing (as the title suggests) a day-by-day, blow-by-blow description of the man’s life.
