Holmes Maine from Massachusetts, Holmes took a prominent part in the Brunswick Convention of 1816. Though not the author of the curious method of counting votes called "Holmes' arith- metic," he signed the report setting it forth and received blame and ridicule for the argument that five-ninths of the aggregate majorities of the town corporations constituted the five-ninths of the legal votes of Maine required by the Mas- sachusetts law authorizing separation (To the People of Maine, 1816). Besides acting as chair- man of the committee which drafted the Maine constitution, he did much to put through Con- gress the bill creating the new state. His pam- phlet (Mr. Holmes' Letter to the People of Maine, Washington, Apr. 10, 1820), wherein he argued that any restriction upon the admission of Missouri would be unconstitutional, was his defense against the opposition of many citizens of Maine to entangling the admission of Maine with the question of slavery extension. Elected senator from Maine in 1820, he retired in 1827, only to be elected the next year to fill the unex- pired term of Albion Keith Parris. In 1833 he again retired to the practice of law. In 1824 Holmes supported Crawford as a can- didate for the presidency. Never a Jacksonian, he transferred his allegiance to Clay and later to the Whig party. In the upper house he defended Foot's resolution, which led to the Webster- Hayne debate, and was active in opposing Van Buren's nomination as minister to Great Britain in 1831. Blair called him the "Thersites of the Senate." In 1836 and 1837 he represented the town of Alfred in the state legislature. Appoint- ed in 1841 United States attorney for the Maine district by President Harrison, he held the office until his death in Portland in 1843. He had pub- lished in 1840 a volume entitled The Statesman, designed to illustrate the "Principles of Legis- lation and Law." He was twice married: on Sept 22,1800, to Sally Brooks of Scituate, Mass., who died Dec. 6, 1835, and on July 31, 1837, to Caroline F. (Knox) Swan, youngest daughter of Gen. Henry Knox, with whom he spent his last years in the mansion at Thomaston, Me. Though he had been notoriously intemperate during the earlier years of his career, late in life he took an active part in the temperance movement. [Win.

Holmes HOLMES, JOSEPH AUSTIN (Nov. 23, i859-July 12, 1915), mining engineer, father of the United States Bureau of Mines, was born in Laurens, S. C, the son of Rev. Z. L. Holmes, a Presbyterian minister with scientific tastes, and of Catherine (Nickles) Holmes. His education was received in the local schools and at Cornell University, where he was graduated in 1881, having specialized in agriculture and science. In the following year he was appointed professor of geology and natural history at the University of North Carolina, where he remained for ten years and where he continued to lecture after he was appointed state geologist in 1891. In addi- tion to his geological studies he showed political ability by inaugurating a campaign for the build- ing of good roads by the use of convict labor and by increased taxes. While still state geologist, in 1903-04 Holmes was put in charge of the de- partment of mines and metallurgy at the Louisi- ana Purchase Exposition in St. Louis. In con- nection with this appointment he took up the test- ing of fuels and structural materials, conducting his demonstrations with such skill that he was put in charge of testing laboratories for the United States Geological Survey. The waste of mineral resources was given much attention in the Roosevelt administration, and Holmes be- came prominent in the conservation movement By 1907 the work with which he was associated had become so important that it was organized as the technological branch of the Survey, with Holmes as its chief. About this time his atten- tion was directed, by a series of disasters, to the investigation of accidents in mines. Explosions and fires in coal mines were taking terrible toll of life, and there was serious need for scientific study and educational propaganda. The techno- logical branch was expanded into the United States Bureau of Mines in 1910, and Holmes, who had worked for the reorganization, was se- lected from several candidates as director. With high ambitions for the success of the new bu- reau, he took up earnestly the problem of the dis- graceful mortality in American mining. A model mine for testing explosions was developed at Bruceton, Pa. Holmes contended that dust from bituminous coal is dangerous by itself, a tenet contrary to the old belief that coal dust could not explode without gas. At the first national mine- safety meeting, organized in Pittsburgh in Octo- ber 1911, mine operators were impressed by the demonstrations. Federal and state rescue sta- tions were established in the coal and metal min- ing regions, and a number of railroad cars were equipped as movable safety and rescue stations. Holmes made popular the slogan "safety first" [67
