Prisons 3835 Privy- probationers. In all prisons certain indus- tries are carried on, varying with different countries and with different parts of large countries. In the United States, for instance, the large prisons of the North engage in manufacturing. In the South, convicts make roads, run turpentine camps, and farm. In World War II, through a special ruling of the Attorney General, State prison industries were converted to war production. The State of New York has erected an agricultural prison for women, where they are taught farming, gardening, bee culture, dairy- ing, and poultry raising by women. The places where criminals are held, both before and after sentence, are known by various names. In addition to the rural lock- up and the city police station, to which the prisoner is first taken, there are penal institu- tions known as houses of correction, work- houses, bridewells, jails, and penitentiaries. The word penitentiary is sometimes used as a synonym for State prison, but in other places, as in New York, it is a county or district prison where misdemeanant prison- ers sentenced for short terms are confined, though occasionally felons are imprisoned there. Architecturally there is a great diver- sity in prisons. The first object being safety, they are massively constructed, the shops and factories being within the walls. Those of the United States, with a few exceptions, have corridors outside the cells, so the sun- light must cross the corridor before reaching the cell. Open-work doors prevent privacy, though giving more access to air and making it easier to guard the prisoners. Modern prisons are supplied with electric lights, baths, good food, libraries* and excellent sanitary arrangements. The effort in the States most alive to reform is to put all convicted prisoners in State institutions and keep jails only for persons detained for trial. The buildings for reformatories are better adapted for their uses than the average pris- on. They have gymnasiums, school rooms, trade schools, baths, graded dining rooms, and special quarters for the different grades. A chapel is an essential feature in every prison, and in many there are three—Prot- estant, Roman Catholic, and Jewish. In ad- dition to the warden, superintendent, or governor of a prison, a chaplain, a physician, and instructors are usually attached to the staff. See CRIMINOLOGY; REFORMATORIES.

In 1900 he was appointed president of the Massachusetts Institute of Tech- nology, resigning in 1906 to become the head of the Carnegie Foundation, where he re- mained until 1930; later becoming pres. emeritus. Private. All men belonging to the United States army who have not attained the grade of non-commissioned officers are termed 'pri- vates' after they are taken up for regular duty with their organization, before which time they are called recruits. See ARMY OF THE UNITED STATES. Privateering, Privateers, vessels of war armed and equipped by private individuals and furnished with a commission or Iicense3 known as, 'letters of marque/ from the state, to cruise against the shipping of the enemy. The commission placed the privateer practi- cally on the footing of a man-of-war, and allowed the owners to keep the prizes which they took, also granting them a certain sum for every man of the enemy taken or de- stroyed. The practice of privateering grew up in the i$th century, and until the middle of the 19th century was generally employed by naval powers. By the Declaration of Paris, in 1856, privateering was abolished so far as the powers signatory were concerned; and in wars conducted since then, even by non-signatory powers, no letters of marque have been issued.

Privet, the popular name of several species of nardy shrubs and small trees belonging to the genus Ligustrum (Oleaceae). Their chief value lies in their use for hedges, as they stand shearing remarkably well. The Japanese privet (L. ovalijoHum)—miscaHed California privet—is preferable for hedge purposes, especially along the seacoast. Privilege. In law this term is used to de- note: (i) certain fundamental political rights enjoyed by all citizens; (2) the exemption from certain legal or political duties or bur- dens enjoyed by a limited number of citizens. Privy Council in Britain is nominally an assembly of advisers to the sovereign on matters of state. At earlier periods of Eng- lish history it exercised large powers, but it ceased to exercise its ancient functions when
