During a November evening
in 1783, a large open boat carried a group of men out onto a mill pond near the
town of Rocky Hill, New Jersey.
Once in the center of the pond, a man in each end of the boat lit a
strip of paper and held it a few inches above the water's surface while the
others took long poles and began stirring up the mud on the pond's bottom. A few minutes later, bubbles of methane
rose through the water, caught fire, and for a brief moment flames spread out
over the pond.
Thomas Paine did not record
what George Washington said when the strip of burning cartridge paper in his
hand set fire to the millpond's surface, just as well perhaps, since it
probably was not suited to a respectable magazine like the INDICATOR. Besides, Paine was busy on the other
end of the boat, holding his own piece of burning paper.
A genial disagreement the
night before brought Washington, Paine, and a group of officers out to the
millpond. But within a few years,
the subject of ³impure² and ³inflammable air² was of serious concern.
Benjamin Franklin first
heard of marsh gas while journeying across New Jersey in 1764. He was skeptical at first. Later by happy coincidence, Franklin
was calling on a friend who had just returned from setting marsh gas on
fire. He explained that by poking
holes in the bottom of a muddy pond with his walking stick, gas would be
released, which was then set on fire with a candle flame. To prove his story, he showed Franklin
the singed ruffles on the clothing he was wearing.
A year later the Royal
Society received a letter from Dr. Samuel Finley, fifth president of Princeton
University or as it was then known, the College of New Jersey. Finley recounted how a man employed a
local mill discovered that the marsh gas could be set on fire and how he repeated
the experiment. The Royal Society
read the letter but did not print it in their Transactions.
According to Franklin, it was considered ³too strange to be true.²
Franklin himself was a loss
to explain the phenomena. He
speculated that volatile oils from pine trees might somehow be transported to
the bottom of the pond. But if
that were the case, what did transport the oil and why couldn¹t it be smelled
either on the surface or in the sediments?
Franklin seems to have
forgotten the matter until 1774 when he met with Joseph Priestley while in
London. Priestley was intrigued by
the phenomena and invited Franklin to contribute a letter for inclusion in his
book Experiments and Observations on Different Kinds of Airs.
By the 1790¹s the causes of
Yellow Fever were being hotly debated by physicians. They knew that people living closer to the water were
generally more susceptible to the disease but its exact cause was unknown. We know now that increased trade with
the Caribbean in the first years after the Revolution brought the disease to
the port cities. At the time,
whether the disease originated in North America or the Caribbean was also
debated.
With remembrances of his
boat trip with Washington on the Rocky Hill mill pond, Thomas Paine joined the
debate. In 1806 he published, The
Cause of Yellow Fever and the Means of Preventing it in Places Not Yet Infected
With It. Addressing his essay to the Board of Health in America,
Paine argued that since the disease was non-communicable, it was unlikely to
have been transported from the Caribbean.
Paine went on to suggest
that the ³impure effluvia² found in river bottom mud was the cause of Yellow
Fever. This mud contained great
quantities of ³impure² and ³inflammable air² which could be released by
disturbing the sediments. It was
known at the time that this material was a hydrocarbon or as it was known at
the time ³carbureted hydrogen gas.²
He argued that new wharf
construction in the seaports released huge amounts of combustible matter in the
river bottoms. Paine¹s solution to
the Yellow Fever outbreaks was to cease using dredged sediments as fill and
construct all new wharfs from stone arches. Arches would allow the tides to flush the river bottoms
clean and so remove the cause of the fever.
Thomas Jefferson praised
Paine¹s essay as ³one of the most sensible performances on that disease that
had come under his observation.²
Yellow Fever of course
remained a serious threat to human health for many more decades.
The crucial turning point
in the centuries long battle against Yellow Fever would create one of New
Jersey's most admired heroines.
Clara Maass (1876 - 1901) was the daughter of German immigrants and an
1895 graduate of the Newark German Hospital School of Nursing. A civilian nurse for the US Army, she
spent the Spanish-American War at hospitals in Florida, Georgia, and Cuba. Maass was serving at the Army's First
Reserve Hospital in Manila when she became interested in Yellow Fever.
In the 1890's, it was still
believed that Yellow Fever was caused by poor sanitation. Under Chief Army Sanitary Officer
William Gorgas, the city of Havana underwent a major cleaning in an effort to
eradicate the disease. When this
failed, Gorgas proposed that inoculation might better protect the public. Meanwhile, an increasingly desperate
American government appointed a Yellow Fever Commission chaired by Major Walter
Reed.
Maass traveled to the Las
Animas Hospital in Havana to join Gorgas's staff. By 1900 it was understood that Yellow Fever was carried by
mosquitoes but it was still thought that inoculation would prove an effective
defense. To test this theory,
Maass agreed to be bitten by an infected mosquito in order to develop
immunity. Her subsequent case of
Yellow Fever was considered too mild for an effective demonstration. She volunteered to be bitten again and
this time, the fever was fatal.
Clara Maass was only twenty-five years old.
Walter Reed later credited
Maass's death with demonstrating to both physicians and the public that
eradicating mosquitoes was the most effective means of combating Yellow
Fever. The Newark German hospital
was renamed the Clara Maass Memorial Hospital in 1918 and continues to honor
memory as the Clara Maass Medical Center.
Methane has long been
recognized as a biomass fuel.
Today about 10,000 homes in northern New Jersey are supplied with
natural gas generated in the Hackensack Meadowlands landfills.
During the 1950's and
1960's Swamp Gas was frequently proposed to explain away sightings of
UFO's. Whether this is the
explanation of the many UFO's seen in the New Jersey remains a mystery.
