Prison Association
AMER- ICAN, an organization of officials of American prisons, founded by Dr. E. C. Wines, of New York, in 1870, at a conference in Cincinnati, O., and incorporated under the laws of New York in the following year. The object of the association was the general improvement of conditions, not only for the officials and employees of such institutions, but for prisoners as well. Until 1877 the vigorous organization developed a growth, issuing reports in 1872, 1874, ng reports and 1877 of considerable value to students of penology. The death of Dr. Wines, however, at this time, caused a notable decrease in the activities of the association, which lasted until 1883, when it again showed signs of revival. The organization is now an influential factor in all movements toward prison reform, and has standing committees on criminal law, reform, prevention, probation, parole, prison discipline, discharged prisoners and prison statistics. With it are affiliated five other national organizations, comprising wardens, prison physicians, prison chaplains, women officials and employees, and criminologists.

Privateer
a ship owned by a private individual, which under govern. ment permission, expressed by a letter of marque, makes war on the shipping of a hostile power. To make war on an enemy without this commission, or on the shipping of a nation not specified in it, is piracy. Privateering was abolished by mutual agreement among European nations, except Spain, by the Declaration of Paris in 1856; but the United States of America refused to sign the treaty, except on condition that all private property at sea, not contraband, should be exempt from capture. This "Marcy," or "American," amendment, as it was called, was not accepted. This doctrine was again affirmed by the United States delegates to the Peace Conference at The Hague in 1898, but was again rejected by the European powers. While not considered PIRACY (q. v.) by the law of nations, they were looked on as little better during the great wars at the end of the 18th and the beginning of the 19th century, and as a rule received but scant mercy at the hands of the regular services.
