POWDERLY, pow'dcrli, TERENCE VINCENT . 

 (1849- ), an American labor and social in- 

 vestigator, was bora at Carbondale, Pa. At 

 about fourteen years of age he began work in 

 a machine shop and was a mechanic for the 

 next thirteen years. He was elected mayor of 

 Scranton, Pa., on the Labor ticket, in 1878, 1880 

 and 1882, and was commissioner-general of im- 

 migration of the United States from 1837 to 

 1902. In 1906 he was appointed special repre- 

 sentative of the Department of Commerce and 

 Labor to investigate the reasons for the heavy 

 immigration from Europe, and in 1907 became 

 chief of the Division of Information in the Bu- 

 reau of Immigration. As a student of present 

 economic and social conditions throughout the 

 world, he became recognized as an authority, 

 for his observation and experience among la- 

 borers have not frequently been equaled. His 

 book, Thirty Years oj Labor, is a valuable re- 

 of the industrial tendencies of the period 

 it covers. 



POWELL, pou'el, JOHN WESLEY (1835-1902), 

 an American geologist and explorer, known es- 

 pecially for his valuable surveys of the Colo- 

 rado River regions. After completing his edu- 

 cation at Oberlin College, in Ohio, he spent 

 several years in research work in natural his- 

 tory and geology. On the outbreak of the War 

 of Secession he enlisted as a private, saw much 

 active service and was promoted to the rank of 

 major. After the conclusion of peace he be- 

 came professor of geology in Illinois Wesleyan 

 University at Bloomington, and in 1867 ac- 

 cepted the chair of geology at the Illinois Nor- 

 mal University. The following summer Powell 

 began a scries of surveys that made him fa- 

 mous. One result of his work was the organi- 

 zation of the United States Geological Survey, 

 of which he was director from 1881 to 1894. 

 His Contributions to North American Eth- 

 nology is a report of the investigations made 

 by him for the Smithsonian Institution on tlio 

 subject of the American Indian. Other publi- 

 cations include Exploration oj the Colorado 



r oj the West and its Tributaries, Canyons 

 of the Colorado and Introduction to the Study 

 of Indian Languages. 

 POWELL, MUD (186&- ), an American 



uist, born at Peru, 111. She was educn 



le public schools of that city, and from 1881 

 to 1885 studied the violin in Chicago, Leipzig, 



.u and Paris. In 1885 she made her first 

 public appearance at Berlin, and within tin- 



next five years gained the reputation of being 

 the greatest of all women violinists. Her work 

 as a soloist with such orchestras as those of 

 Thomas, S'edl, Nikisch and Damrosch proved 

 that no requirements of technique, volume or 

 tone were too difficult for her, while her fre- 

 quent tours of America, Europe, Asia, South 

 Africa and Australia have not impaired the 

 freshness and inspiring character of her play- 

 ing. It has frequently been declared that she 

 has introduced more new violin music to the 

 public than any other musician in America. In 

 1904 she married H. Godfrey Turner of London. 



POWER, in arithmetic and algebra, the re- 

 sult obtained when a quantity is multiplied by 

 itself a specified number of times. The second 

 power, or square cf a number, is found by mul- 

 tiplying the number by itself once; the prod- 

 uct obtained by taking a number three times 

 as a factor is the third power; four times, the 

 fourth power, and so on. Thus, the second 

 power of 6 (written 6 2 )=6X6, or 36, while the 

 third power (written 6') =6X6X6=216. The 

 degree of the power, or the number of times 

 the given quantity is taken as a factor, is ex- 

 pressed by a number called the exponent, 

 which is written to the right and above the 

 quantity, as 6 3 , 3 being the exponent. The 

 process of finding a power of a number is called 

 involution. 



The second power of a quantity is found in 

 estimating the area of square or circular sur- 

 faces, while the third power aids in finding the 

 cubic capacity of solids. 



POWER OF ATTORNEY, a legal instrument 

 authorizing the person named in it to act as 

 the agent or the attorney for the one who 

 signs it. If the power of attorney is to be 

 recorded it must be signed by a notary pub- 

 lic. A general power of attorney authorizes 

 the agent or attorney to act for the principal 

 without limitation. A special power limits him 

 to the act or acts specified in the instrument. 

 Courts place close construction upon the power 

 of attorney, requiring the agent to keep strictly 

 within the limits of the instrument. The death 

 of the principal revokes the power of attorney.
