It is perhaps obvious to any student of Biology that the discovery
of chemical processes in whole organisms has usually preceded the
elucidation of the compo nent steps. However, it is perhaps less
obvious that the unravelling of the se quences in which those
chemical steps occur in living matter, of the precise mechanisms
involved, and of the manner in which they are regulated, would have
been achieved neither by the study of intact plants and animals nor
even of extracts derived from them. Our ability to understand the
nature and regulation of metabolism rests on two main premises: the
postulate that life processes can indeed be validly investigated
with individual cells and cell-free extracts, and the thesis that
there is an essential "unity in biochemistry" (as Kluyver put it,
60 years ago) that enables events in one organism to be
legitimately studied in another. Of particular utility in this
latter respect has been the use of cultures of single-celled
organisms, growing in defined media-especially prokaryotes, such as
Escherichia coli, and eukaryotes, such as Neurospora and Sac
charomyces sp. , to which both biochemical and genetical techniques
could be applied. It was, of course, Pasteur's observations of
bacterial fermentations that first overthrew the belief that oxygen
was essential for all energy-yielding pro cesses: his recognition
that "La fermentation . . . . . c' est La vie sans air" laid the
foundations of our knowledge of glycolysis.
This collection takes on the call issued by reviewers of The
American Way for a critical application of Carville Earle's
framework to more geographical examples of political and economic
shifts in America's past. The essays illustrate changes in U.S.
settlement, development, and political structure through the lens
of the restructuring of the American economy and society over
approximately fifty year cycles of crisis and recovery. They
demonstrate the extension of American's sphere of influence outside
of the United States as a larger scalar shift, and they underscore
the utility of geography in answering very local questions
concerning questions of poorly documented settlement histories.
Focusing on the geographic responses to periodic cycles of crisis
and recovery and the more general underlying intertwining of
geography and history, Geography, History, and the American
Political Economy is an incisive demonstration of how the constant
restructuring of American politics and economy occurs within
spatial and historical constructs.
