A CENTURY OF GEOLOGY IN INDIANA. 173 



of the area, this being in large part compiled from the writings of Dr. J. 

 Sehneck and Robert Ridgeway. 



In addition to the Ditney and Patoka folios, the U. S. Survey has to date 

 eonjpleted the topographic map sheets of twelve quadrangles in southwestern 

 Indiana, the region covered comprising parts or all of most of the coal measure 

 counties south of the National Road. The names of these quadi'angles, each 

 of which covers about 930 square miles, are as follows: Clay City, Vincennes, 

 Petersburg, Princeton, Boonville, Haubstadt, Velpen, St. Meinrad, De 

 Gonia Springs, Mt. Carmel, New Harmony and Owensboro. They have also 

 issued topographic sheets of the Bloomington quadrangle* which covers the 

 western half of Monroe, southeastern corner of Owen and the eastern third 

 of Greene County, and in northwestern Indiana the Tolleston quadrangle 

 covering the northern third of Lake County and a portion of the southern 

 end of Lake Michigan. It is presumed that the folios of tiiese respective 

 quadrangles Avill ))e issued as fast as the geologic work on them is completed. 



The above constitute the more important papers relating to the geology 

 and archaeology of Indiana published outside the State Reports between 

 1869 and 1910. Other short ones of minor importance published before 1893 

 are mentioned by Marster^ and Kindle in their "Geologic Literature of 

 Indiana (Stratigraphic and Economic)," a bibliographic paper published in 

 the Proceedings of the Academy for 1893. A number have also appeared in 

 the ditTerent volumes of the U. S. Geological Survey and the Proceedings of 

 the Indiana Academy, where they can be readily found by anyone 

 interested. 



The Blatchley Survey, 1895-1910. 



In April, 1894, the present v/riter, then serving as the "Head of the De- 

 partment of Science in the Terre Haute High School," was chosen in the 

 State Convention from a field of four as the candidate for State Geologist on 

 the Republican ticket. Looking back from a viewpoint of 22 years, the re- 

 cipient of that honor realizes that in that convention he had the only real 

 political battle of his life, and that his victory was won not by himself (for 

 in political lore he was then the veriest tyro) but by the combined efforts of 

 his friends, chief among whom were a score or more of the older members of 

 this Indiana Academy of Science, to whom today he takes pleasure in giving 

 due credit for his first nomination. In November, 1894, he was elected over 

 his Democratic opponent, Mr. K. T. .1. .Jordan, for a term of four years, and 

 was renominated and re-elected in 1898, 1902 and 1906, and renominated 

 but defeated at the polls in 1910. His successor, Mr. Edward Barrett of 

 Plainfield, is also a member of your Academy, and has served as State Geol- 

 ogist since January 1st, 191 L
