Thoreau's Thoughts on Walking

See also a March 2017 posting on poem "The Old Marlborough Road."

"If you are ready to leave father and mother, and brother and sister, and wife and child and friends, and never see them again; if you have paid your debts, and made your will, and settled all your affairs, and are a free man; then you are ready for a walk."

May 2017: U.S. Post Office issues a first class stamp honoring
the bicentennial of the birth of Henry David Thoreau.

July 12th was the 200th anniversary of the birth of Henry David Thoreau. [Actually, birth-named David Henry Thoreau after his deceased uncle, David Thoreau. Thoreau reversed the order of his names shortly after he graduated Harvard College, in 1837. Apparently, growing up, his family had called him Henry rather than David.] The Thoreau Society recently held its annual gathering of Thoreauvians, to discuss all things Thoreau, and to celebrate the bicentennial of his birth. Many newly published books, and the U.S. Post Office issued a stamp.

“Walking” was the title of one of his essays. His first public reading was at the Concord Lyceum on April 23, 1851. Between 1851 and 1860 Thoreau read from the piece a total of ten times, more than any other of his lectures. “Walking” was published in the June 1862 issue of the Atlantic Monthly, shortly after his death from tuberculosis at age 44. The essay’s length is slightly more than 12,000 words. Various internet sources have the complete essay available on line – some with researchers’ annotations. A few excerpts:

“The West of which I speak is but another name for the Wild; and what I have been preparing to say is, that in Wildness is the preservation of the world.” Thoreau felt that it was necessary for one’s soul to be able to walk in wildness every day. He was aware, however, that his Massachusetts terrain was not true wildness, but rather a post-colonial return of once-farmed land to wild meadow and forest. Thoreau's three excursions to Maine had brought him into true wildness ("grim"), so he knew the difference.   

Thoreau was not a casual walker. “It is true, we are but faint hearted crusaders, even the walkers, now-a-days, who undertake no persevering, never-ending enterprises. Our expeditions are but tours and come round again at evening to the old hearth side from which we set out. Half the walk is but retracing our steps. We should go forth on the shortest walk, perchance, in the spirit of undying adventure, never to return; prepared to send back our embalmed hearts only, as relics to our desolate kingdoms. If you are ready to leave father and mother, and brother and sister, and wife and child and friends, and never see them again; if you have paid your debts, and made your will, and settled all your affairs, and are a free man; then you are ready for a walk.”

Thoreau’s opinions were not humble opinions: “I think that I cannot preserve my health and spirits unless I spend four hours a day at least — and it is commonly more than that — sauntering through the woods and over the hills and fields absolutely free from all worldly engagements… When sometimes I am reminded that the mechanics and shop-keepers stay in their shops not only all the forenoon, but all the afternoon too, sitting with crossed legs, so many of them — as if the legs were made to sit upon, and not to stand or walk upon — I think that they deserve some credit for not having all committed suicide long ago.”

Wooden dumbbells were a popular type of
exercise equipment in the 1800s.
Thoreau was aghast at the idea of exercise for its own sake: “But the walking of which I speak has nothing in it akin to taking exercise, as it is called, as the sick take medicine at stated hours — as the swinging of dumb-bells or chairs; but is itself the enterprise and adventure of the day. If you would get exercise go in search of the springs of life. Think of a man’s swinging dumb-bells for his health, when those springs are bubbling up in far off pastures unsought by him.”

Thoreau cherished the meditative rewards of wildness walking: “I am alarmed when it happens that I have walked a mile into the woods bodily, without getting there in spirit. In my afternoon walk I would fain forget all my morning occupations, and my obligations to society. But it sometimes happens that I cannot easily shake off the village. The thought of some work will run in my head, and I am not where my body is; I am out of my senses. In my walks I would fain return to my senses. What business have I in the woods, if I am thinking of something out of the woods?”

A human trial conducted at Stanford University (Bateman 2015) concluded that walking surrounded by nature reduced risk of depression more than walking an equal amount of time in an urban setting.

Boston Post Cane - Maynard and Stow

The Boston Post was a popular and influential newspaper some 100+ years ago.  In 1909, Edwin Grozier, the publisher, decided to promote the newspaper by donating ebony shaft, gold-capped canes to the Boards of Selectmen of 700 towns in Massachusetts, Maine, New Hampshire and Rhode Island.  Engraved on the top of the gold head of each cane were the words "Presented by The Boston Post to the OLDEST CITIZEN of __________ [name of town and state] (To be transmitted)."

The idea was that the towns would award these BOSTON POST CANES to the oldest male citizen for the remainder of his life, to be returned to the town upon his death, to be awarded to the next oldest, and so on.

Maynard's Boston Post Cane (click on photo to enlarge). This cane was
presented to Maynard in 1909, awarded to a series of men in honor for
being the oldest male resident, went missing in 1928 and was recovered
in 1981. Honoring the oldest resident (male or female) started again in 1999.
The canes were made by J.F. Fradley and Co., a New York City silversmith and cane maker. Joseph F. Fradley (1843-1914) began a silversmith business in 1866. His business had an excellent reputation. J.F. Fradley items appear for sale in  fine arts and crafts auctions. The business was managed by his son, George F. Fradley, at the time the canes were made. Although many of the newspaper articles about recipients of Boston Post Canes describe the cane heads as 14 karat gold, some of the internet photos show wear to reveal non-gold metal underneath, confirming that the cane heads were gold-plated rather than all gold. This makes sense. Gold, rather than gold plated, would have made the canes prohibitively expensive, even back in 1909.  

Women achieved the right to vote in 1920, but it took ten more years before The Boston Post approved a changing of the rules to allow women to be awardees.  

The Boston Post went out of business in 1956, but the Boston Post Cane tradition continues in many towns. As years went by some of the canes were misplaced, stolen, sold, lost or destroyed. Some went missing for years, decades even, only to surface again. In time, most towns decided to keep the original cane in a town office or at the local historical society, and either discontinue the practice entirely or else award a plaque to the oldest resident in lieu of the cane. 

The Boston Post Cane Information Center [http://web.maynard.ma.us/bostonpostcane/], maintained by the Maynard Historical Society has become a clearinghouse for all things BPC. The starting point was a 1985 article written by Maynard historian Ralph Sheridan. After his death in 1996, David Griffin took up the traces, and still gathers news of canes lost, found and awarded.

Side view, showing ebony shaft of the cane. "Ebony"
comes from the heartwood of several species of tropical,
slow-growing trees. It is black or near-black in color, and
extremely dense (will sink in water). The tree species are
endangered, and in many countries, harvesting or selling
of ebony is illegal. Well known uses include the
black keys of pianos, and parts of stringed instruments.
A few facts plucked from the BPC website: As of last count, 517 towns continue or have resumed honoring their oldest citizens. Most have the original canes gifted them in 1909, but some are using brass-capped mahogany replicas purchased from the Town of Peterborough, NH. Some towns stipulate that to qualify, a person must be a current resident and living in the town the past 10 or 15 years. Watertown's cane went missing in 1910, and did not return until 99 years later. At the time Mary Josephine Ray of Westmorland, NH, passed away, age 114.8, she was not only the oldest ever holder of a Boston Post Cane, but also the oldest person in the United States.

Stow's Boston Post Cane is kept in the Town Vault in the Town Hall building, along with other historically important artifacts. Recipients are presented with a Boston Post Cane lapel pin. The cane had gone missing 1951 to 1971. Actually, it was in the Vault all the time, but misplaced. Since 1971 there have been 12 recipients. The most recent was Dr. Donald Freeman Brown - awarded the cane when he reached 99 years. He passed away in 2014, age 105. The honor and lapel pin have not yet been awarded to a new oldest resident.

Top of cane showing non-gold metal. This may be silver. If so,
there may have been layers of copper and nickel between the
silver and gold, to prevent tarnish bleeding through the gold.
Maynard's Boston Post Cane is on permanent display at the town building. It had gone missing around 1928, not recovered until 1981. In 1999 the Maynard Historical Society decided to revive the tradition of honoring Maynard’s oldest citizen by presenting him or her with a plaque from the Maynard Board of Selectmen. The most recent five: Elizabeth Dodd, Dorothy Barlow, Arlene Cook, Mildred F. Duggan, and currently Ben Sofka. Ben, a life-long Maynard resident, received his plaque in February 2017, and is at present 101 years old.

Stow's and Maynard's neighbors do and do not continue the Boston Post Cane tradition. Hudson, Harvard and Sudbury awards plaques to their most senior citizens. Acton is considering restarting the same practice. Bolton and Boxborough apparently do not participate, either because these towns had too small a population to get a cane back in 1909, or because the original canes went astray. Starting in 1962, Concord decided to change to an annual Honored Citizen Celebration. The awardee is steward of the Boston Post Cane for a year and leads the Patriots' Day Parade.

Ticks: Lyme, Anaplasmosis, Babesiosis

From left to right: larvae, nymph, adult male, adult female.
Nymphs and adult females are the vectors for human infection.
Ticks get on your shoes, socks or legs when you brush against
vegetation. Ticks do not drop from above. The CDC website
recommends chemical repellants, also how to do a tick check
and how to wash and dry clothes to kill ticks.
June and July are the prime months for contracting a tick-borne disease. During these months the vector is the nymph stage, which is about the size of a poppy seed. There is a lessening incidence in August, September and further into fall and winter, as the vector becomes the more easily seen adult female tick (the size of a small apple seed), and also because people spend less time outdoors with the onset of colder weather.

An observation here: the term 'bite' is not descriptive. If not detected, a nymph will latch on for 3-4 days for a blood meal before dropping off; adult females stay attached for 7-10 days. Adult males are not on you for a meal. Rather, they are wandering around looking to find and fertilize a female. This meet-and-mate part of the tick's life cycle is the reason that deer are integral to a region harboring a serious tick disease problem. Small mammals (mice, chipmunks, etc.) are vectors for the larval and nymph stages to become infected, but a large mammal species such as deer is essential for the mating and final blood meal that allows the fertilized adult female tick to lay up to 3,000 eggs.    

Lyme, Anaplasmosis and Babesiosis are the big three for New England, but the full count for tick-borne diseases now overtops a dozen. More information on tick-vector diseases can be seen as the Centers for Disease Control website: http://www.cdc.gov/ticks/. The CDC has great information on the tick diseases, and also on practical matters such as how to avoid getting bitten by a tick, and what to do once you have been bitten.

Lyme starts subtle. If the stricken person missed the actual bite, then the first sign is often but not always the signature "bull's eye" rash. Moderate fever, chills, fatigue, muscle ache and a headache may accompany the rash. Only months after the rash and the initial set of symptoms are gone is there a possibility that really bad consequences set in: arthritis, partial facial paralysis, meningitis, limb weakness, and so forth.

Anaplasmosis is not subtle. The symptoms are more akin to being run over by a car, having it circle around to hit you again, and then one more time to park on your head. Some 7 to 10 days after the bite the symptoms arrive all at once: extreme fatigue, high fever, uncontrollable shivering alternating with profuse sweating, night sweats, headache, nausea, abdominal pain, loss of appetite, weight loss, muscle pain, cough, mental confusion, and extreme fatigue. Really extreme.

Babesiosis is not subtle. Symptoms, arriving 10-30 days after being host to a tick, are akin to those of Anaplasmosis, plus it destroys red blood cells and platelets. From the latest data published by the CDC, Massachusetts has more cases of Babesiosis than any other state.

The CDC uses the term "malaise," but this does not convey the soul-crushing lethargy of either of these full-speed infections. Not everyone exhibits all the symptoms, and many of these symptoms overlap with what people expect if they have the flu, causing many people to delay seeking a medical evaluation, or doing so, getting a misdiagnosis.

Actually, these days, diagnosis and treatment are straightforward. Do you have some or all of that litany of symptoms, especially fever and fatigue? Were you in any place a week or four ago where there might have been ticks? That's it. A blood sample will be taken, but especially early in the course of the infection the test results can be false negative (says you don't, but you do). Standard medical practice is to start antibiotic treatment immediately. Treatment should never be delayed until the lab results are back. These days, there is an assumption that more than one disease is transmitted from the same tick, so for Babesiosis, doctors may prescribe multiple antibiotics.

Neither casual contact nor intimate sexual contact will pass on any of these diseases, but receiving a blood transfusion has been a confirmed vector. There are no laboratory screening tests to verify that donated blood is not infected. 

Not treating infections in a timely fashion can have very serious consequences. Delayed treatment may require hospitalization and intravenous antibiotics. Especially in older or immuno-compromised people there are risks of compromised breathing, kidney failure, nerve damage and death. A practical point - your guests can contact a tick disease here, then travel to regions where doctors may not have tick disease awareness. Your parting words might include "Safe travels, and if you develop a rash or become ill, tell your doctor you were in tick territory."

Wolves Repopulate Massachusetts - NOT!

Before Europeans arrived in North America, what is now the 48 contiguous states, i.e., all but Alaska and Hawaii, was home to an estimated 250,000 wolves. And 10 to 20 million deer. Nowadays the estimates are 5,500 wolves, and 25 to 30 million deer. There has been lobbying to restore wolves to the east, much as was done for bald eagles, but no action expected in the near, middle or distant future. Because it is one thing to restore the national symbol, and another to have the big, bad wolf wandering about the Berkshires.  

The anti-wolf movement started ten years after the Mayflower landed. In 1630, the Massachusetts Bay Colony approved a bounty for each wolf killed. Other colonies followed suit, at times switching back and forth between bounties paid to anyone and professional hunter/trappers. The first cause for this animosity was to stop depredation of domestic animals - cattle, sheep and pigs. Wolves had been eradicated in England and Scotland long before colonization to the Americas, so while the settlers had folklore of the depredations of wolves, actually losing livestock was a rude jolt.

By 1840 there were no more wolves in Massachusetts. Henry David Thoreau had lamented that of New England's wild life, nothing larger than foxes remained. Wolf extirpation followed in neighboring states, so by 1900 there were no more wolves in New England.

The practice of killing wolves to make land safer for pastured sheep and cows shifted west as Americans moved west. In time, a second cause evolved. The early decades of colonization treated wildlife as an inexhaustible resource. Deer were hunted for family consumption, but also for the market for meat that grew as cities grew. In time, game became scarce, hunting for market was banned and the concept of licensed sport hunting matured. Wolves were hunted, trapped and poisoned so there would be more deer and elk to be shot for sport. Anti-predator attitudes extended to mountain lions and coyotes.  

What was learned, slowly, was that without apex predators, herbivores will multiply to beyond what the greenscape can support. Starting in 1994, a great experiment was conducted in and around Yellowstone National Park. Thirty wolves were trapped in Canada and released in the Park. Within ten years the population peaked at approximately 300. It has since declined to half that due to pack-to-pack competition for territory and out-migration. The elk population declined from 20,000 to what may be a stable 5,000. Mule deer, moose and bison populations showed little change. Spending by hunters is way down, but is more than compensated by wolf-related tourism. 

There have been other interesting consequences. The coyote population has been halved, but the grizzly bear and cougar populations stayed stable. Bald eagles and ravens - scavengers at wolfkills - increased in number. With the end of over-grazing by elk much plant life recovered, bringing biodiversity.

The concept of "ecology of fear" came out of this experiment. When animals continuously fear predators, behavior changes. More time spent on surveillance and staying nearer to safe havens means less time eating. Less time eating slows growth and reproductive success. Locally, our examples of animals without fear include turkeys and geese.

There are proposals to restore wolves to upstate New York and northern Maine, which in time would result in populating surrounding regions. A big question: Will wolves attack people?  Nineteenth century newspaper accounts describe wolf packs attacking and eating children, adults, even armed adults who managed to kill some of the wolves before dying. Wolf attacks on humans are very rare now, but the main cause is that wolves are rare. What is being reported are increasing numbers of attacks on dogs. Hunters that use off-leash dogs for licensed bear hunting are reporting dog kills in Idaho, Wisconsin and other states. Pet dogs have been taken in parks in Minnesota.

There is an argument for a net benefit from restoring wolves to the east. Currently, 150-200 people die each year from vehicle collisions with deer. Restoring wolves would reduce that number, perhaps at the cost of 1-2 deaths per year from wolf attacks. Logical? Yes. Emotionally reassuring? No. One solution would to be equip a wolf or two per wolfpack with a GPS device and have a wolf app on your smart phone.

Not in the newspaper column: In 2007 a wolf was shot in Shelburne, Massachusetts, after reports of an animal killing sheep and lambs. DNA testing confirmed the 85 pound male animal as a gray wolf. The nearest known wild wolf population was in Canada, some 350 miles away. Back in elk country, the estimates are that wolf packs will kill 22 elk or other large ungulates per wolf per year. Deer being much smaller, it could mean more than 50 deer per wolf per year! Meanwhile, there have been scores if not hundreds of documented coyote attacks on humans, sometimes by rabid animals and sometimes not. Two attacks have resulted in deaths - a three year old child (1981), and a 19 year old woman (2009). Rabies more commonly affects raccoons, skunks and foxes, but can cross to coyotes. A common sign of rabies is a loss of fear of natural predators (and humans), abnormal behavior, such as being active during daylight hours for a species typically nocturnal, and aggressive biting.

Bald Eagles Repopulate Massachusetts

Bald eagles don't have to be fast, only strong. The majority of their diet is either fish or stuff already dead, competing in the latter situation with vultures, ravens and crows. Adults weigh 9-13 pounds (females are larger than males), and can easily lift a 3-5 pound fish out of the water. An eagle that ends up in the water - perhaps after grasping a too-large fish - can take off from the water's surface. Bald eagles also prey on young Canada geese, ducks and small mammals. And steal food from other predators, such as ospreys.

Bald eagle, Lake Boon 2011 (Martin French)
Bald eagles are in the genus Haliaeetus, common name sea eagles, of which the Steller's Sea Eagle* is the largest. Of the some 60 eagle species worldwide, our bald eagle does not make the top five for weight or wingspan. All eagle species are long-lived. For the bald eagle, lifespan in the wild often exceeds 20 years. In captivity, lifespan has been known to exceed 50 years.

During nesting season the mated pair are both involved in egg-sitting and bring food to the young - typically two - eaglets. The parents each need close to a pound of food per day, and the growing eaglets not much less, so an adequate food supply is essential to raising a family    

According to the Commonwealth of Massachusetts, there were 56 nesting pairs of eagles in the state in 2016, up from 51 the year before. The process of restoring eagles to this state began in 1982. Over a six year period, 41 eagle chicks were collected in Canada and released in the Quabbin Reservoir area. The chicks fledged, i.e., reached flying age, at 11 to 12 weeks. Most survived the next critical period of six weeks during which hunting, flying (and landing) skills were improving. In a normal situation the young chicks would have been fed every 4 to 5 hours by their parents, but in this relocation program the human caregivers wore a hand puppet that looked like an adult eagle's head. The effort to restore eagles to Massachusetts was part of the federally funded Northern States Bald Eagle Recovery Plan.

The effort worked. Young eagles take four to five years to reach sexually mature adulthood, including a slow transition from juvenile all-brown tones to adult coloration, during which time they wander hundred of miles but tend to return to the general area where they were born to seek a mate and start raising families. By 1989 the relocated eagles were starting to nest in the Quabbin region. Since then, nesting sites have been spreading east and west. The nearest to us is in Framingham. Any local eagle sightings are of wanderers - either juveniles that have not yet paired up or adults during the non-nesting part of the year, which runs from mid-July to mid-January.

and beak has not yet turned yellow. (Internet photo)
In Colonial times, an estimated 250,000 to 500,000 bald eagles populated what would become the continental United States, i.e., excluding Alaska and Hawaii. But by the 1970s, through a combination of hunting, loss of habitat and the unexpected effects of DDT spraying for mosquitoes, the number of nesting pairs had dropped to under 500. Through a combination of banning of DDT in 1972, the Endangered Species Act (1973) and the relocation programs, nesting pairs now exceed 10,000 and the species is no longer considered endangered. It is still protected by the Bald and Golden Eagle Protection Act.**

Lead poisoning continues to be an issue. The most significant hazard to wildlife is through direct ingestion of spent lead shot and bullets, lost fishing sinkers, or through consumption of prey containing lead shot or bullet fragments. While lead was federally banned for waterfowl hunting in 1991, its use in ammunition for other hunting remains widespread.

For many years, I half-remembered, or perhaps remembered half, of a short poem about birds of prey. While not specifically about bald eagles, it does capture a predator's sudden brutality. As remembered:

In the woods, I heard a scream.
Whether it was bird of prey
   or prey of bird,
I do not know, I only heard.

And then, while working on this column, I remembered the book I had read it in. So, as actually written:

BY NIGHT
After midnight I heard a scream.
I was awake, it was no dream.
But whether it was bird of prey
Or prey of bird I could not say.
I never heard that sound by day.
   - Robert Francis

*Steller's Sea Eagle: Georg Wilhelm Steller (1709-1946) was a naturalist on a Russian expedition to the Bering Sea in 1740. This eagle is 1.5 times the weight of the bald eagle. Adult females are known to top 20 pounds. Diet is mostly fish. In addition to the sea eagle, other species bearing his name are the Steller's Jay, Steller's Sea Lion, and Steller's Sea Cow. The last, a relative of manatees and dugongs, was hunted to extinction within decades after Steller's identification of the species.

**The Golden Eagle is native to North America, but unlike the Bald Eagle, not limited to North America. Golden Eagles prey primarily on small mammals, and prefer open plains and mountains to densely wooded terrain. But they do wander east as far as Massachusetts, and can be mistaken for immature Bald Eagles. The original federal Act (1940) protected only Bald Eagles, but was extended to cover Golden Eagles in 1962.
