J. Hector St. John de Crävecoeur's Letters from an American Farmer--the semi-autobiographical series of essays first published in 1782--is like an acorn in which the whole gnarly tree of fundamental American obsessions can be found in embryonic form: the addled affair between civilization and the land; the myth of the frontier; the ethic of individualism; the tension between liberty and equality; the melting pot; slavery. Moore (English/Florida State Univ.) has edited this new volume of essays, which Crävecoeur (17351813) left unpublished and which were discovered more than a century after his death. Like the more celebrated Letters, these are essays in the form of reportorial letters to Europe about life in the new American country. Among the topics addressed in these further letters are: ``Hospitals,'' ``Liberty of Worship,'' ``Frontier Woman,'' and ``Landscapes.'' Moore offers a scholarly introduction and a cautious editorial hand that, striving for the feel of a manuscript, retains ampersands and archaic (or at least idiosyncratic) spellings.
