The Gorby Survey, 1889-1894. 



Since polities and not rocks had been the chief subject of discussion in 

 the interim, it was foin* years between the issue of the sixteenth report, the 

 last one put out by Thompson, and the seventeenth, the first one published by 

 Gorby. The latter was a volume of 705 pages without an index. The usual 

 introduction is followed by a paper of 96 pages entitled "A Report upon the 

 various Stones used for Building purposes and found in Indiana," by Maurice 

 Thompson who, in spite of his health, continued to act as chief assistant. One 

 half of the paper is given to detailed statistics of the quarries of the State. 

 Reports upon the geology of Steuben and Whitley Counties by Chas. R. Dryer, 

 Carroll County by Maurice Thompson and Wabash County by M. N. Elrod 

 and A. C. Benedict follow in the order mentioned. The report on Steuben 

 Coimty includes "A Partial Catalogue of the Flora of the County," by E. 

 Bradner, 729 species being mentioned. 



These county reports are followed by those of the State Inspector of Mines, 

 the State Supervisor of Oils and the State Supervisor of Natural Gas, these 

 officers having been made appointees of the State Geologist during the political 

 turmoil of the past four years. 



As crude petroleum had been discovered in paying quantities in the Trent- 

 on Rocks of Indiana in 1891, there is a short paper entitled "Petroleum in 

 Indiana," by A. C. Benedict, in which the facts regarding the discovery are 

 set forth and the history of petroleum from the earUest time treated some- 

 what in detail. 



The reports of these officers are followed by two papers of interest to the 

 zoologist. The first, "A Catalogue of the Butterflies known to Occur in 

 Indiana," was by the present writer. It comprised 44 pages in which 108 

 species were listed, with sj'nonymy and notes on distribution and life habits. 

 In the quarter of a century that has passed, but three additional species 

 have been recorded from the State. 



"The Batrachians and Reptiles of the State of Indiana," by Dr. O. P. 

 Hay, then Professor of Zoology in Butler University, was a more extended 

 paper, comprising keys, full descriptions and life histories of all the known 

 Indiana species of this interesting group of vertebrates. 



The final paper on paleontology is by S. A. Miller. It is devoted wholly 

 to the descriptions of new species from Indiana, Missouri and other states, 

 and is accompanied by 20 plates. The author must have had as much trouble 

 in finding new names for his species as does the Pullman Company at the 

 present time for its sleeping cars, as 13 are named (7or6?/z, &vebenedicti, three 

 collcUi and nine indianaensis. 



Second Report of Gorby. 



The second volume issued by Gorby appeared in 1894 and contained 

 356 pages and 12 plates. In it Dr. Chas. R. Dryer, published the results of 

 his Avork in 1893 upon the Geology of Noble and LaGrange Counties, and
