Maine Coast Shipwrecks---a Marine Archaeologist's Treasure
Trove
Four
centuries of misfortunes that befell early mariners and fishermen have
left a legacy of maritime sites that sheds light on shipbuilding techniques
and daily shipboard life. University of Maine history and marine sciences
professor, Warren C. Riess shared his diving adventures and the results
of his research with the April Portland Harbor Museum lecture audience.
Maine's
first mariners, Riess explained, were local Native Americans who made
the waters abundant fish supply a dietary staple. Archaeologically research
on several of the Casco Bay has turned up evidence of their economic and
domestic lifestyles.
The first representations of European ships along the Maine coast show
up in surprisingly accurate petroglyphs done by Native Americans. Riess
pointed out that attempts to identify the ships from their carved images
often runs into cultural problems. The height of the poop deck of the
carving, for example, towers over the same structure in a European drawing
of the vessel. Riess consulted art historians who proposed the theory
that to the Native American carvers, the importance of an object portrayed
is proportional to its height. They suggest that the horizontal line of
the ships waist is probably closer to scale.
European
mariners and fishermen began exploiting the Maine coast in the latter
half of the 16th century. Europe's burgeoning population made the catching
and preserving of cod an important industry. The rectangular structure
was called a stage and gave the name Stage Island to this island and a
few other Maine coast islands.
Riess pointed out that diving and excavation of a site comprises a small
part of a marine archaeologist's work load. Full exploitation of a site
continues with conservation and interpretation any recovered artifacts
and can run up to 15 years.
Before
serious work begins the prospective site must be researched to determine
if the project is worthwhile and if necessary funding and resources are
available. Recovered artifacts must be painstakingly cleaned and treated.
"Every piece of glass or metal has its own characteristics and
presents its own preservation problem to stabilize it for posterity,"
said Riess. "Finally, the results of an archaeological study must
be made known to the world and related to research on similar projects.
Does it reinforce other studies or does the new research present a contradiction?"
The
site of the wreck of the "Nottingham Galley" on Boon Island
presented a dilemma for Riess and other marine archaeologists. They long
had been aware of several cannons a few feet underwater on the Boon Island
ledges. The dilemma arose when they were told by local fishermen that
sea urchin divers from Massachusetts had their eyes on the cannons. Although
laws were in place forbidding the removal of marine artifacts, enforcement
was not likely to stall a few determined
looters. The archaeologists convinced state authorities that one cannon
recovered was worth two stolen from the ledge and received permission
for their removal. Nine cannons were in fragile condition were recovered.
"They were mostly carbon held together by a little iron," said
Riess. "When a student put his hand into the muzzle of one of them
a big chunk of the metal fell away. We painstakingly cleaned marine growth
out of the muzzles, painted them with a tannic acid preservative and applied
a coat of wax."
Riess
pointed out several other marine archaeology sites strewn along the Maine
coast. In 1779 An ill fated US naval task force sent to defeat a British
attempt to erect a fort on the Penobscot River left behind a marine archaeologist's
treasure trove of shipwrecks. At the appearance of the 40 ships of the
US armada, the British commander of the half-built fort was getting ready
to shake out a white flag of surrender.
"Both
sides had good spies," said Riess. "The British commander was
holding onto his white flag hoping for reinforcements while the Americans
were looking over their backs to see if they would be overtaken. Luck
was with the British commander. An arriving fleet of five heavy British
frigates with half again as much fire power as the 40 smaller US ships
sent the US fleet fleeing up the Penobscot River.
The subsequent marine hare and tortoise race up the Penobscot left behind
30 wreck sites. When it look as though a British frigate was about to
overhaul an American vessel it was run onto the river bank and torched.
A few like the "Defense" sank in deeper water.
In
the 1970s the "Defense" wreck site off Sears Island became a
vehicle for training archaeology students from around the world. The wreck
tells a lot about how 18th century shipboard life was conducted. The curious
looking wooden daggers, for example, are meat tags that served as primitive
kitchen timers.
The crews were divided into "messes" for the allotment rations.
Each mess appointed a mess captain who was responsible for food preparation.
The mess captain accepted his mess's ration of heavily salted beef and
plopped into a tub of boiling water along with chunks from the other messes.
When the cooking time for his rations was up the mess tag identified it
from others that had been started earlier or later.
Riess
recalled one "Defense" recovery as "the most exciting peak
of my career." "We were feeling our way in the inky black water
when I laid hands on a medicine chest with some of its contents still
intact. One of the bottles contained a sulphur remedy for stomach disorders.
Another, filled with a black substance, was sent of a pharmaceutical firm
for analysis. It proved to be a mixture of turpentine and pine sap. The
pharmaceutical lab said it was a headache remedy that worked much the
same an asprin.
Work on the Defense site was abandoned in the late 1980s. Riess said
that the attempts to care for the many Penobscot River sites were getting
beyond local resources. He convinced the U.S. Navy of the value of the
many early warship relics scattered along the Penobscot. "It was
a tough call," said Reiss. "We had found most of them, but it's
good that the navy has put its resources behind preserving a valuable
piece of maritime history for future generations to study and enjoy."
