some
of the worst land in the country.18 O'Grada estimates
that at the time of the famine about 3 million people depended on just
such a potato monoculture.19 Further, Woodham-Smith
cites the 1836 Poor Inquiry as stating that 2.39 million Irish were
already "in a state of semi-starvation every year, whether the potato
failed or not."20 As Crawford describes,
"Cereals, meat, and butter continued to be widely consumed
among the better off during the 18th and early 19th centuries, but for
the poor potatoes largely took their place as more and more meat, butter
and grain were exported. On the eve of the famine, however, cereal-based
foods were not available to most of the poor, who neither grew grain
nor had the money to buy it."21
Beginning in 1845, the famine swept through and cut out the means of
support for the most marginal people in society. But it also did much
more. Through the wake of the famine traveled two diseases that commonly
accompany scarcity: dysentery and typhus. Both diseases caused mass
mortality-"relatively few died from actual starvation, the majority
succumbing to diseases which were collectively described by one medical
observer as 'famine poison.'"22 However, typhus usually
killed the rich while the poor most often succumbed to dysentery. Mortality
rates increased as the infections climbed the social ladder, leading
to a theory that the poor had built up more immunity to the more deadly
typhus than had those in higher social strata.23 Both
diseases were spread by a body louse that spread from person to person
thanks to the concentrations found at poor relief facilities such as
the soup kitchens.
