Questions 20-29
In the 1820s, the exhaustion of commercial oyster beds along the northeastern coast
set the stage for the industry that would shift the Chesapeake Bay region located in
the southern state of Maryland forever from an underdeveloped subsistence economy,
and define its culture for the next 150 years. In the early nineteenth century, the
Chesapeake oyster beds, perhaps the world’s richest trove of the shellfish, were
discovered. Following the Civil War in 1865, the exploitation built to the fever pitch
of a gold rush. More than 1,000 sail craft, including four-masted schooners, sloops,
pungeys, and bugeyes, dragged heavy iron dredges ceaselessly across the “rocks,”
as the reeflike agglomerations of the shellfish were called, catching oysters by the
hundreds of bushels a day.
At the height of this activity, the Chesapeake region probably was less isolated than
at any time in its history, including present times. In 1886, the oyster harvest peaked
in Maryland at some 15 million bushels, an annual production of edible meat equal to
the yield from 160,000 head of cattle. The oyster fleet employed a fifth of everyone
involved in fishing in the United States. Oyster captains ruled the waves, outgunning
attempts to enforce even modest conservation by the Maryland Oyster Navy, charged
with policing the oyster beds. On the positive side, the oyster industry of this era used
its political clout to force the nearby city of Baltimore to construct the nation’s most
modern sewage treatment plant to protect the water quality of the bay. So intense was
the oystering that it eventually altered the physical shape of the bay’s bottom, breaking
apart the reefs in which oysters naturally grew. Studies comparing old charts of the bay
bottom to new bathymetric surveys have found a dramatic flattening of original bottom
contours. This made oysters more susceptible to silting over, and perhaps more
vulnerable to the diseases that now plague them—though this latter is still speculative.
As harvests slid from the unsustainable peaks of the 1880s never to return, people
involved in harvesting oysters sought an easy-to-build, cheaper alternative to the big
sail dredge craft which would require fewer crew. What evolved was a beamy vessel,
usually 38 to 55 feet long, the bottom made with simple crosswise planking. It could
be built by a good backyard carpenter, and hundreds were.
