Pennypacker 3667 Pensacoia halfpence and farthings in 1672, for pennies in 1786. Pennypacker, Samuel Whitaker (1843- 1916), American public official, was born in Phcenixville, Pa. He served with the troops called out to resist the invasion of Pennsyl- vania in 1863 and in 1902 was elected gov- ernor of Pennsylvania. Pennyroyal (Mentha pulegium), the pop- ular name of a mint common in Europe and Western Asia. The whole plant has a char- acteristic fragrance, Penobscot, a tribe of American Indians which in early colonial times occupied the territory along the Penobscot River, the lar- gest river in Maine. Penobscot Bay, a bay on the coast of Maine. Penology, that branch of criminology which deals with the punishment of criminals in both its deterrent and reformative aspects. Such punishment undoubtedly had its origin in private vengeance, passing as society devel- oped, under the authority of the state. Be- cause of the almost universal practice of im- prisonment as a punishment for crime, the emphasis of modern penology is largely upon prison management. The honor system, has been tried in certain State prisons, chiefly in the West. Groups of convicts are sent out to work on the roads or on farms under some- what relaxed discipline, being put on their honor not to attempt escape. In 1932 about 65 per cent of productive prison labor was under the state-use system. Of the prisoners not at productive labor, 52,986 were engaged in various prison duties; 6,658 were on the sick list; 17,027 were idle. Overcrowding in prisons is a serious problem. Management of prisons is a fairly new science, discussed by Lewis E. Lawes in Sing Sing, by Thomas Mott Osborne, and by 0. F. Lewis in Development of American Prisons. The indeterminate sen- tence system at Elmira Reformatory, depend- ent on the individual factors of a case, is an interesting experiment. Much attention has been attracted by the system of self-government introduced by Thomas Mott Osborne at Auburn and Sing Sing Prisons, New York State. The prisoners are organized in a Mutual Welfare League, in which membership is open to all. The League is in almost complete control of the discipline, and the prisoners enjoy large priv- ileges as to correspondence, freedom to see visitors, recreation, etc. The past century has witnessed a remarkable advance in the gen- eral matter of the punishment of criminal of- fenders. Riots, however, and disorder show that not all the problems have been solved. See PRISONS. The State Medium Security Prison at Wallkill, N. Y. is designed to be an educational factor. It is a new experiment in criminal rehabilitation, one of the present problems of penology being to fit inmates for gainful employment. Professional penolo- gists now seem opposed to isolated prisons. The Georgia penu.1 system, the chain gang, has met much criticism also, although it is ably defended. The psychiatrist is taking a leading place in modern penology. The factors, individual and social, which make for the prevention of crime are now considered more the subject of research than are the penalties inflicted. In recent years penologists have advocated the separation of youthful and first offenders from the hardened criminals, and some prog- ress has been made along these lines. The Federal government has built a prison ori Alcatraz rock in San Francisco Bay for dan- gerous and incorrigible criminals. The build- ing on the huge rock, which is surrounded by the swiftly running waters of the Golden Gate, is believed to be absolutely escape- proof and the prisoners are permitted few of the privileges common to the average peno- logical institution. Penrose, Boies (1860-1921), American legislator and political leader. In 1897 he was elected United States Senator, and was re-elected in 1903, 1909, and 1915. He served as chairman and member of important com- mittees in the national Senate and became the leader of the Republican Party in that body. For more than two decades, Penrose was master of the Pennsylvania Republican machine when that machine ruled the state. He became chairman of the powerful Finance Committee of the U. S. Senate and was cred- ited with guiding the choice of Warren G. Harding as Republican Presidential nominee from his sickbed in 1920. He was an im- portant factor in Republican Presidential campaigns from 1896 until his death. Penrose was supposed to have joined with Senator Thomas Platt of New York in nominating Theodore Roosevelt for the Vice-Presidency in 1900 in an effort to get Roosevelt out of Platt's way in New York State politics. "Power and Glory," a life of Penrose by Walter Penrose, was published in 1931. Pensacoia, city, Florida, county seat of Escambia co., on Pensacoia Bay, It has a splendid land-locked harbor.
