Abstract
THE contents of this volume refer very largely to the economic natural resources of the State of Indiana, and embrace the results of the work accomplished by the different divisions of the Department under Mr. Blatchley's administration during the year 1896. The papers deal with the petroleum industry in the State, composition of Indiana coals, Indiana caves and their fauna, the geology of the middle and upper Silurian rocks of Clark, Jefferson, Ripley, Jennings and Southern Decatur Counties, the oölitic limestone of Indiana, the natural gas of the State, the geology of Vigo County, and the uncultivated ferns and fern allies and the flowering plants of the same county. Several excellent plates illustrate the report, and the whole volume shows that the State, which twenty years ago was noted mainly for her agricultural products, possesses great natural resources, and is rapidly assuming high rank as a mineral producing and manufacturing centre.
