382 STEVINUS active member of the whig party. In 1833 and for several succeeding years he was a member of the Pennsylvania legislature, and he became distinguished by his opposition to slavery. He was appointed a canal commissioner in 1838, and rendered important services to the state in the promotion of her system of internal im- provements. In 1842 he removed to Lancaster, and for six years devoted himself to his profes- sion. He was elected representative in congress in 1848 and reflected in 1850. He strongly opposed the fugitive slave law and the Kansas- Nebraska bill. He was again elected to con- gress in 1858, and held his seat till his death. In his latter years in congress he was a recog- nized chief of the republican party, and took the lead in all measures for emancipating and arming the negroes and for giving them citizen- ship. He also advocated acts of confiscation and other severe measures against the confed- erates ; and he was chairman of the managers for the impeachment of President Johnson. STEVINUS, or Steyln, Simon, a Flemish mathe- matician, born in Bruges about 1550, died at the Hague about 1630. The particulars of his life are unknown. In 1586 he published in Dutch a work on " Statics and Hydrostatics " and "Anew System of Fortification;" in 1589 a tract on the motion of the heavens ; and in 1599 a treatise on navigation (translated into Latin by Grotius, Ley den, 1624). In 1605 Wil- lebrord Snell translated into Latin most of the works of Stevinus, but died before completing the translation. In 1634 Albert Girard pub- lished at Leyden all his works in French, in- cluding a collection of geometrical problems. See Simon Stemn, by Quetelet (Brussels, 1845). STEWARD, Lord High, in England, the highest officer under the crown, who was formerly known by the Latin title of magnus seneschal- lus. Under the Plantagenets the office was hereditary, and was held by the house of Lei- cester, until forfeited by Simon de Montfort. Since the reign of Henry IV. it has been abol- ished as a permanent dignity, and is conferred for some special occasion, as a trial before the house of peers or a coronation. The lord high steward presides at the former, and at the close of the proceedings breaks his wand and dissolves the court. The office of steward, or Stewart, also existed from early times in Scot- land, and gave name to the royal family of Stuart, in which it was hereditary from the time of David I. (1124-'53) till the accession to the throne of Robert (II.) Stuart, grandson of King Robert Bruce, in 1371. STEWART. I. A S.

He studied at Trinity college, Dublin, but did not take a degree, emigrated to New York in 1818, and engaged in teaching. In 1823 he began, at No. 283 Broadway, a business which has gradually expanded into one of the largest mercantile concerns in the world.

In March, 1869, President Grant appointed him secretary of the treasury, but his confirmation was prevented by the law which excludes from that office all who are interested in the importation of merchan- dise.
