The growth of government during this century has attracted the attention of many scholars interested in explaining that growth and in proposing ways to limit it. As a result of this attention, the public choice literature has experi- enced an upsurge in the interest in anarchy and its implications for social organization. The work of Rawls and Nozick, two volumes edited by Gordon Tullock, Explorations in the Theory of Anarchy, and a book by David Friedman, The Machinery of Freedom, provide examples. The goals of the literature have varied from providing a conceptual framework for comparing Leviathan and its opposite extreme to presenting a formula for the operation of society in a state of anarchy. But nearly all of this work has one common aspect; it explores the "theory of anarchy." The purpose of this paper is to take us from the theoretical world of anarchy to a case study of its application. To accomplish our task we will first discuss what is meant by "anarcho-capitalism" and present several hypotheses relating to the nature of social organization in this world. These hypotheses will then be tested in the context of the American West during its earliest settlement. We propose to examine property rights formulation and protection under voluntary organizations such as private protection agencies, vigilantes, wagon trains, and early mining camps. Although the early West was not completely anarchistic, we believe that government as a legitimate agency of coercion was absent for a long enough period to provide insights into the operation and viability of property rights in the absence of a formal state. The nature of contracts for the provision of "public goods" and the evolution of western "laws" for the period from 1830 to 1900 will provide the data for this case study.
