Fever And The Miasma: The Tale of Levi Chapin Comes To An End

(This is last part of the story.  Follow the hyperlinks to Part One and Part Two)

Yellow Fever Microbe (CDC slide)
Under a high-powered microscope, the organism that causes yellow fever looks pretty harmless; you can see it on the left.  In fact, it looks a lot like an exemplar of museum-quality abstract art.

Looks, of course, can be greatly deceiving.

If Levi Chapin died of yellow fever in eastern Virginia in September of 1833, we can know one thing with absolute certainty– it was not an easy way to die.

The disease gets its name from the yellow color that the victim’s fevered skin and eyes often turn.  In the Spanish-speaking tropics, it’s called by another symptom-descriptive name: “vomito negro” or “black vomit”. High spiking fever, icy chills, vomiting and bone-wracking pain are a few of the tell-tale symptoms of the disease once called “yellow jack”.

Today, when we speak of yellow fever – a disease that only a few U.S. physicians specializing in tropical medicine will likely ever see first-hand, we use cold, clinical terms like “flavivirus”, “arbovirus”, and “arthropod”.  We speak of etiology, vectors and vaccines. None of those terms were in common use in the early 19th century. 

What was first called “bilious remitting yellow fever” was a terror-inducing medical mystery, seemingly arising out of nowhere.

Of course, back then, people thought that cholera could be “caught” by eating under-ripe fruit and that malaria was the result of bad air.

Back then, nobody knew exactly why yellow fever happened, or exactly how to cure it. People spoke of “the miasma” and burned tar in roadways to ward off the disease. They quarantined ships in harbors so that sailors wouldn’t spread the disease by breathing on or touching the uninfected. Some thought the disease was caused by rotting vegetable matter; others saw it as God’s punishment for one thing or another.

Collecting the Near-Dead in 1793 Philadelphia
Yellow fever epidemics periodically carried off sizable portions of the urban population, especially in southern cities like Savannah and New Orleans. Still, prior to 1822, some northern urban areas suffered as well.  Estimates of deaths during the Philadelphia epidemic of 1793 were in the 4,000 – 5,000 range.  Carriages roamed the cobbled streets to collect the dead and the nearly-dead.  Note the pedestrian in the picture at right above covering his mouth so that he doesn't "catch" the disease.

In some communities, officials did not permit the burial of yellow fever victims in local cemeteries.  The disease was thought to be contagious long after death and some feared that whatever caused it lived on in the ground. Graves were dug in remote parts of potters’ fields and if an epidemic caused large numbers of deaths in a community, yellow fever mounds – mass graves of hasty burials – became a common sight.  

 Even as late as 1905, some municipalities such as Minneapolis had public health ordinances that classed yellow fever as a highly contagious disease along with cholera, smallpox, typhus and measles.  Bodies of persons who fell victim to these diseases had to be disinfected, placed in metallic caskets and buried as quickly as possible, with no viewing and only a private family funeral permitted.

If Levi Chapin had fallen victim to yellow fever in 1833 Virginia, it is highly unlikely that his body would have been returned to New Hampshire for burial. Fear of the disease would have dictated otherwise.

By the 1830s, the disease seemed largely confined to southern coastal and river cities.  The fever severely struck Norfolk and Portsmouth in southern Virginia in 1855. Even later, in the summer of 1878, about 20,000 people died in the Mississippi Valley, with the cities of Memphis and New Orleans being hit the hardest.

When New Orleans physician John James Hayes wrote his short handbook titled Yellow Fever: Its Nature, Cause, Prevention & Cure in 1858, he thought he had all the answers.  He wrote:

The disease called Yellow Fever results from a deficiency of atmospheric air in the lungs; from a want of the adequate quantity of it in the lungs; and consequently from a want of the due changes imposed by it on the circulating fluids; from a want of one fluid being converted into blood, and a want of the other being duly eliminated.

Dr. Hayes thought it was all about “air and fluids.”  Observing that the New Orleans poor suffered the most during the summer yellow fever season, he recommended a temporary lifestyle change.  He suggested that “the poor should quit their confined, badly ventilated houses, which, during an epidemic season—a hot season —I would call ovens, and live in the open air, in a free exposure.

Aedes aegypti
The true cause of yellow fever – a microscopic flavivirus spread by Aedes aegypti mosquitoes – would not even be suspected, let alone proven, for many decades after Hayes’s spectacularly bad advice to the New Orleans poor to sleep outside… with the mosquitoes.

Not surprisingly, yellow fever was always news, whenever it occurred.  Even reports of a few isolated cases in places far from home made the local newspapers all over the country during the 19th century since local editors speculated that those few cases might be harbingers of a much larger epidemic. Then as now, newspaper folks liked to be on top of epidemic disease stories, even though nobody knew that mosquitoes were the real culprits.

So, if Levi Chapin had actually contracted yellow fever in Virginia in September of 1833, there is a very good chance that the newspapers would also have reported some evidence of the disease in some part of Virginia around that same time.  In fact, there were numerous yellow fever stories in US newspapers during the month of September 1833, but they were all about the outbreak and progress of the New Orleans epidemic.  Virginia, Washington and Maryland were not mentioned.  Moreover, I have not yet located any newspaper that reported Levi’s death.

If Levi actually died of yellow fever, no newspaper of consequence took notice. Here’s what they were writing about (from The Newburyport [MA] Herald, 13 September 1833)



There are lots of newspaper stories on New Orleans, but none about yellow fever in eastern Virginia around mid September of 1833.
 
So, perhaps that part of the story is wrong as well.  Unconfirmed and uncorroborated family stories are interesting to read and speculate upon, but they carry no real weight as evidence. Think of them as clues that goad us on to investigate things just a little bit more.

So, the results of this inquiry into the circumstances surrounding the death of Levi Chapin are mixed, but not completely unproductive. Evaluating the quality of the evidence we find is part of what we do as researchers. Facts get weighed and sifted; new discoveries can sometimes prove old evidence to be faulty.

We now know that the 1862 Chapin genealogy conflated Levi’s brother and nephew who were both named Stephen, and got Levi’s year of birth wrong.  We now know that while the 1963 History of Walpole, New Hampshire was right about Levi being an inventor and having patents (plural), the description of those patents was incorrect.  We now know, thanks to an early 19th century journal, exactly what Levi invented and how it was supposed to work. We now know that Google Patents has lots of interesting information, but not for those early patents issued prior to the 1836 fire at the Patent Office. We now know that researchers can use the Journal of the Franklin Institute to re-capture some of the information that was lost in that fire. And that the Google Patents “Search/ Optical Character Recognition (OCR)” software still needs a bit of work. Plus, we know lots more about moulding planes and 19th century tool-making than we know when we started.

Still, we do not know if Levi Chapin actually died of yellow fever in eastern Virginia in 1833. We do not know if he ever actually visited his son Philip in Baltimore or his nephew Stephen in Washington.  Why he chose to travel to Virginia in the first place is currently lost to history, as is the final disposition of his patents – the “Improved Chapin Hanging Saw” seems not to have made much of a mark in the sawmill business.

In fact, the inquiry process itself raises a few questions not previously considered. For example, let’s suppose that Levi Chapin actually did die of yellow fever, as they stories say. The early symptoms of the disease often take nearly a week after exposure to appear. Could Levi have visited New Orleans, been bitten there by a virus-carrying mosquito, and then returned to Virginia by boat, shaking and feverish, thinking he had a bad case of some flu-like illness? Moreover, are there other records in archives in Baltimore or Washington – when his close kin lived – that could shed more light on his demise and his travels?

There are now many more lines of inquiry to consider in the quest for facts about the life and death of Levi Chapin and I’ll continue to explore them as opportunities present themselves. Not all family history problems have easy solutions, but since much of the thrill is in the hunt itself, finding a few new doors to open and more clues to explore is its own reward.

Finally – there’s one other minor thing of genealogical interest that came to light while searching through Google Patents.  Plug in a bunch of related family names, and all kinds of curious things come out . . .

On 5 April 1870, a man living in Alton, Belknap County, New Hampshire named Smilie Tilton received patent number 101,545 for an “improved extension table.”  Smilie Tilton – who also invented and patented an “improved” wooden cheese wrapper and an “improved” calf-muzzle -  was married to a woman named Mary Elizabeth Bancroft (1840 – 1886) who was born in New Hartford, Connecticut.

Turns out that Mary E. Bancroft was the granddaughter of Westfield, Massachusetts plane maker Nathaniel Chapin and thus, the great-granddaughter of Levi Chapin – the man whose death sparked the search and this series in the first place.

There’s no doubt in my mind that inventor-entrepreneur Levi Chapin would have likely approved of his great-granddaughter’s choice of an inventor-husband.  He may even have liked the feel of the wood that Smilie used to make the model of his “improved” extension table, pictured in the patent file below.

Maybe it was even Chapin wood, from a Chapin family tree in Walpole, New Hampshire about a hundred miles away.

Wood, Tools, Factories and Patents – Part Two of the Continuing Tale of Levi Chapin

(Note: this is Part 2: Part 1 is here)

Trees.   Logs.   Boards.   Wood.  

For most of the early 19th century, the family of Levi Chapin of Walpole, New Hampshire and wood, in all its various manifestations, were largely inseparable.

In the earliest days, it began with the trees themselves on Levi’s 800-acre farm.  The trees were harvested, hauled and trimmed by the Chapins, sawn in the Chapin's sawmill, turned into lumber and then sent down the river to Springfield, Massachusetts to be re-formed into the rapidly growing community’s houses, stores, offices, and furniture.

If you had an ancestor living in 19th century Springfield, her kitchen table or cellar door may have been made with wood from Levi Chapin’s farm. The planks that floored her bedroom may have been smoothed by one of Levi’s sons. Her parlor fireplace mantel may have started as a thousand pound piece of a hundred-year-old tree hauled off a hill by a Chapin horse.

Levi’s five sons grew up surrounded by the work wood makes, in all its manifestations.  There were trees to be cut.  Bark to be removed. Sawdust to be swept up.  Firewood to be sawn and split.  Logs to be transformed into boards by those unforgiving mill saw blades.

Their lives were circumscribed by the sound and smell of wood:  trees falling, axes and saws pounding and ripping, fires of waste wood crackling, and the dull thud of a never-ending supply of boards being stacked in higher and higher piles for shipment elsewhere.

With sawdust in their lungs and tree sap in their blood, the Chapin boys were almost made of wood, and wood was made for these Chapins.

It’s no surprise that three of Levi’s sons chose careers that were dependent upon wood.  Eldest son Nathaniel (1792 – 1876) joined his brothers Hermon (1799 – 1866) and Philip (1805 -1887) in a place called Pine Meadow (part of the town of New Hartford), Connecticut in a moulding-plane making venture for a few years.  In time, both Nathaniel (the grandkids’ ancestor) and Philip moved away to run their own factories, leaving Hermon to become the Connecticut “King of Moulding Planes and Ruler of Rules.”

Moulding planes tend not to be on most genealogists’ radar.  Say “wood planes”, and the average genealogist thinks of something that you buy at a hardware store to take the rough parts or high parts off a piece of wood.

But moulding planes are something entirely different; in fact, in order to understand moulding planes, you need to learn a new vocabulary, with words like “astragal”, “ogee”, and “cavetta”.  These are words that describe the shapes – the moulding profiles - that are made by hand tools known as moulding planes. 

So, what exactly are “moulding profiles”, you might ask?  After all, in all your years of doing family history, nobody has ever asked you to know what an “ogee moulding” is.

The best way to explain this is to suggest you tour a 19th century house with all its original mouldings.  Crown mouldings where walls and ceilings meet, chair rails set partway up the walls, and fireplaces where stylized mouldings abound. If you can, actually run your fingers across the moulding and feel the smooth curves, sharp angles and the grain of the wood.

All those fine mouldings that you see in 19th century historic houses in Connecticut and Massachusetts were likely made on the spot when the house was built.  There were no lumber stores or Home Depots where those fancy mouldings were sold by the linear foot; housewrights and carpenters used moulding planes – often from one of the Chapin plane factories – to make their own interior mouldings by hand.

The patterns of the moulding – the curves and thrusts and angles – are called the moulding profiles. And an “ovolo moulding” looks like this:



This shape is made by craftsmen using a wood plane that looks something like this one:

For years, New England craftsmen sought out the Chapin brothers’ planes for their quality and cutting edge. Some Chapin planes bear the mark of Nathaniel, the brother who set up shop in Westfield, Massachusetts: they’re stamped “N. Chapin & Co. Eagle Factory Westfield”.  Others bear Hermon’s mark: “H. Chapin Union Factory   Warranted”. 

Hermon’s plane and rule making enterprise in New Hartford was very successful. When his son Philip (named after his father’s youngest brother) inherited it in 1866, he took himself a wife and built himself a house to reflect the Chapins’ success story.  The house, I’ve learned, is currently for sale.  If you have $785,000, you too can live like young Philip Chapin. 

Here’s the link that underscores the fact that in the age before power tools and mass marketing, the manufacture of high-quality planes and carpenters’ rules could make you wealthy. 

Nathaniel and Hermon’s youngest brother Philip’s planes were not much used in New England; after he learned plane-making in New Hartford with his brother Hermon, he set off south to Baltimore, Maryland where, in time, he became a prosperous and prolific plane maker. Planes stamped “P. Chapin. Balto.” are heavier and bulkier than the New England planes.

Chapin planes are now museum pieces and collector’s items.  The Connecticut Historical Society in Hartford has both a large collection of Chapin planes and lots of archival material from the Chapin factory in Pine Meadow.You can search for it in the CHS online catalog.

Interestingly, Philip, Levi’s youngest son, was living in Baltimore at the time that it is said that Levi made his trip south to eastern Virginia, ostensibly to “…dispose of his patents.”  And Baltimore is close to Washington D.C.  And eastern Virginia.

Keep that thought in mind for a bit while we talk about patents.

In 1793, the U.S. Congress passed the Patent Act, placing the issuance of patents under the Secretary of State’s office.  There was little in the way of stringent review like there is today:  if you were a citizen, your payment of $30.00 and the submission of a drawing, a description, and a working miniature model of your invention, usually got you a United States patent.

In 1810, the federal government purchased a building in Washington known locally as “Blodgett’s Hotel” and began renovations to use it as the headquarters for both the Post Office and the Patent Office. 

Things were simpler then.

Fast forward to the present. 

Several years ago, the folks at Google announced a new free tool:  Google Patents, direct from the USPTO (the official United States Patent and Trademark Office).  It’s described on the Google website as follows: Google Patents covers the entire collection of issued patents and millions of patent applications made available by the USPTO, from patents issued in the 1790s through the present.

If you have an inventor-ancestor, you can play with Google Patents here. One thing to bear in mind, though: the character recognition technology that Google Patents uses leaves a lot to be desired.  For example the name “Robert Amory” – pretty clear on his printed 1924 patent for manufacturing blankets – is rendered by the search function as “BOBEPT AMOBY

 Quirky search function notwithstanding, Google Patents sounds great, right? If there’s a “Levi Chapin” patent for some kind of an improvement to water wheels, it should appear on Google Patents.

Problem is, when you use Google Patents, no “Levi Chapin” patents appear.

That’s because there’s one little event that the Google Patents FAQ blurb completely glosses over: the “Great Patent Office Fire” of 15 December 1836. The fire totally destroyed Blodgett’s Hotel and virtually all of the early patents burned up.  Estimates are that nearly 10,000 patents were destroyed in the fire, with only a very small number escaping destruction.  Congress later permitted the “restoration” of 2,845 patents, using the information from private files. So, while it’s correct to say that the Google Patents records go back to the 1790s, it would be more correct to point out that most of the earliest records no longer exist.

What now?

Fortunately, the Franklin Institute of Philadelphia began publishing a periodical journal in 1826, making it the second oldest continuously published scientific journal in the country.  In the early days, one of their regular features in each issue was a large section called “American Patents” in which they reported on and described the latest patents issued by the Patent Office.  

Currently the journal concentrates on engineering and applied mathematics, and should you feel compelled to subscribe, all 10 issues a year can be yours for one low yearly subscription payment of $2,633.00.

It was much less expensive in Levi Chapin’s day.

On page 30 of Volume 5, issued in 1830, the Journal of the Franklin Institute reported that a patent (number 5676) for “an improvement in the mode of Hanging and Straining Saws” had been issued to Levi Chapin of Walpole, New Hampshire on 13 October 1829. A few years later (January 1833), a notice appeared describing another patent (number 7099) for “an improvement in the Saw Mill” issued to Levi Chapin, Walpole, Chester County [sic], New Hampshire on 1 June 1832.  Each issue described Levi Chapin’s invention in detail, so that by referencing the Journal, interested descendants can read what the inventions were actually supposed to do.

So, Levi Chapin actually had patents, even though you can’t find them using Google Patents, since they’re from the “burned” period. 

Note, however, neither patent described in the Journal of the Franklin Institute “improves water wheels” in any way, as the Walpole New Hampshire history suggests.  They’re all about saws and cutting wood. Remember, these Connecticut River Valley Chapins were all about wood, in all its manifestations.

Also remember Levi’s youngest son Philip.  Philip, still unmarried, lived in Baltimore and made planes at the time his father Levi is reported to have died in eastern Virginia of yellow fever. Eastern Virginia is close to Baltimore.

Philip appears in Matchett’s Baltimore Directory in the edition of 1835 – 1836 at 36 Light Street:


 
So, overall, the information that appears in printed sources is close to accurate, but not truly on the mark.   It wasn’t his brother in Washington; it was his nephew.  His patents were not to improve water wheels; they were all about sawing wood. In my former career, we used to describe this kind of thing as “good enough for government work”, however, it’s not quite good enough for family history.

Therefore, the question arises: did he intend to “sell” his patents, as the Walpole history relates, or did he plan to license them to mill operators?  And since his son Philip lived in Baltimore and his nephew Stephen in Washington, was his visit south actually a family visit/ business trip or something else altogether?

And, of equal interest, what about his contracting yellow fever and dying in September of 1833?  What can we learn about that, if anything?

Stay tuned! There's more to come!
