ROCKINGIIA9I, Charles Watson Wentworth, mar- quis of, an English statesman, born May 13, 1730, died July 1, 1782. Distinguished by wealth and character, he succeeded in 1765 George Grenville as first lord of the treasury and premier, and henceforth was the leader of the liberal branch of the aristocracy. Although his ministry contained members who had voted against the passage of the stamp act, it did not undertake to repeal it, but made preparations to execute it in all the colonies ; but this prov- ing impracticable, the repeal took place in March, 1766, accompanied by an act declaring the supreme power of parliament over America in all respects. Rockingham retired from the premiership on July 12, but resumed it in March, 1782, on the resignation of Lord North. ROCK ISLAM), a N. W. county of Illinois, separated from Iowa on the N.

W. by S. of Chicago; pop. in 1850, 1,711 ; in 1860, 5,130; in 1870, 7,890; in 1875, estimated by local authorities at 12,000. It is opposite the W. extremity of Rock island, from which it derives its name. This island, the property of the United States, is 3 m. long, covering 960 acres, is well timbered, and has graded avenues and handsome drives. During and previous to the Black Hawk war it was the site of Fort Armstrong, a series of block houses, and during the civil war an extensive prison for the detention of confederate prison- ers of war was situated upon it. Here is the Rock Island arsenal and armory, intended to be the central United States armory. The de- sign embraces ten immense stone workshops, with a storehouse in the rear of each, besides officers' quarters, magazines, offices, &c. Four of the workshops are already completed (1875). The shops will be supplied with motive power from the Moline water power, three fourths of which is owned by the government. The main channel of the Mississippi is N. of the island. Across the S. channel, from the upper end of the island to Moline, 111., a dam has been con- structed by the United States government, af- fording extensive water power. The Moline water power is 2 m. E. of the city of Rock Isl- and ; the Milan water power in Rock river, 3 m. S. of it. Rock Island is the headquarters of the Rockford, Rock Island, and St. Louis railroad, the S. W. terminus of the Western Union railroad, the "W. terminus of the Peoria and Rock Island railroad, and a station on the Chicago, Rock Island, and Pacific, and the Chi- cago and Southwestern railroads, which here cross the Mississippi on the railroad and wagon bridge built by the government in connection with the arsenal. The railroads and river af- ford excellent facilities for shipment, and the abundant water power gives ample opportuni- ty for manufactures. The principal establish- ments are a plough and cultivator factory, a stove foundery, a window-glass establishment, a cotton factory, three lumber mills, and three breweries. There are three national banks, a private bank, four large public school buildings, four denominational schools, two newspapers with daily and weekly editions, and 13 church- es, viz. : African Christian, Baptist, Christian, Episcopal, German Lutheran, Methodist, Pres- byterian (2), Roman Catholic (2), Swedish Baptist, Swedish Lutheran, and United Pres- byterian.
