A CENTURY OF GEOLOGY IN INDIANA. 175 



southern Indiana were studied and classified, and the area covered by each 

 of the type soils shown on accompanying maps. Surveys had previously 

 been made of eight counties by the U. S. Bureau of Soils so that the survey 

 of 40 counties had been completed by 1910. Mr. Barrett has since continued 

 the soil survey work and has covered most of the remainder of the State. 

 In addition to the more important economic papers above mentioned, there 

 were numerous shorter ones scattered throughout the volumes. 



Now the writer wishes it distinctly understood that he did only a small 

 proportion of this work. While he planned it and in great part directed it, 

 the major portion Avas done by his assistants; by George H. Ashley, now 

 Director of the Coal Surveys for the U. S. Geological Survey; T. C. Bopkins, 

 now Professor of Geology in Syracuse University, N. Y.; E. M. Kindle, now 

 Paleontologist for the Canadian Geological Survey; Claude E. Siebenthal, 

 now in charge of one of the Divisions of the U. S. Survey; A. E. Taylor, now 

 at the head of one of the Departments of the U. S. Soil Survey, and Chas. W. 

 Shannon, now State Geologist of Oklahoma. They and a score of others served 

 as assistants during the sixteen years that the writer was Director of the 

 State Survey. All were loyal, efficient helpers who did their share and did it 

 weU. Each was given full credit for his work, his paper appearing under his 

 name and his alone in the volume in which it was printed. Looking out 

 upon them now where they occupy positions of honor and of trust at the 

 hands of the nation or of other states, I am proud to remember that they 

 did their first work at a meagre salary on the Indiana Geological Survey 

 between the years 1895 and 1910. It was the recognition of the value of that 

 work, by persons competent to judge, that brought tliem first and lasting 

 renown as geologists and as scientists. 



Taking up the more purely scientific or secondary phase of the work as 

 set forth in the second sentence quoted, the writer concluded that since the 

 Department was first christened the "Department of Geology and Natural 

 Science," and later the "Department of Geology and Natural History," 

 that its founders had in mind the study of all forms of living things in addi- 

 tion to the rocks and fossils. Again several of the older members of the 

 Academy of Science had the results of a number of years of observation and 

 study locked up in manuscript form, for which at that time there appeared 

 no avenue of publication. It was decided therefore, that if possible, a part 

 of each annual volume should be devoted to one or more papers on the botany, 

 zoology or paleontology of the State. There appeared, therefore, in the 

 volumes as issued, monographs or other important papers on the crayfish of 

 the State by Hay; the cave fauna by Blatchley; the birds by Butler; the 

 moUusca by Call and Daniels; the dragonfiies by Williamson; the flowering 

 plants and ferns by Coulter; the Devonian fauna and stratigraphy by Kindle; 

 the Orthoptera by Blatchley ; the stratigraphy and paleontology of the Niagara 

 of Northern Indiana by Kindle; the insect galls by Cook; the fauna of the 

 Salem limestone by Beede and Cumings; the spiders and other Arachnidae 

 by Banks; the stratigraphy and paleontology of the Ordovician rocks by
