Repoet on the Mines and Mining Exhibit. 315 



nnprinted bnlletin forms the appended report by Mr. Ileinrich Bies, 

 who made the cla;^ collections for the exhibit at the World's Fair. Mr. 

 liies was the assistant in cliarge of the installation of the mining 

 exhibit, and performed his duties in a manner alike creditable to him- 

 self and to the State. 



The iron ores exhibited by the State were obtained by correspond- 

 ence and supplemented by specimens from the museum. The supei^ 

 intendent experienced great difficulty in securing satisfactory specimens 

 of salt for display. Mi'. R. D. "White, C. E., was iii'st sent out to visit 

 the manufacturers of salt in the State and to select and arrange for the 

 shipment of the different kinds of their product. The companies did 

 not feel that the exhibits would be of linancial value to them, and were 

 reluctant to involve themselves in any expenditure of time or labor. It 

 became necessary to send Mr. "William C. Clarke, E. M., on an addi- 

 tional trip before satisfactory arrangements could be made to present a 

 proper exhibit. The study of the gypsum industry had already been 

 placed in the hands of Mr. Clarke, and his results are published in 

 Bulletin No. 11 of the New York State Museum. 



The building stones of the State were chiefly collected by corre- 

 spondence and were prepared for exhibition in ten-inch cubes, one face 

 receiving as high a polish as the stone was susceptible of, and the other 

 faces being prepared so as to bring out ,the individual peculiarities of 

 the stone. The work of cutting and polishing these stones was done 

 by the firm of Schilling & Co., of Albany, who also prepared the 

 stones for the geological obelisk. Mr. Seward M. Savage, E. M., made 

 a tour of the Adirondack i-egion to solicit and secure specimens for the 

 building stone collection and the geological obelisk. Mr. "William G. 

 Eberhard, E. M., visited the quarries of bluestone and flagstone in 

 order to obtain specimens of the same. It is proper here to express 

 thanks to Prof. "William B. D wight, of Vassar College, for his laborious 

 efforts to secure for the geological obelisk, stones from the Cambrian for- 

 mations of Washington and Dutchess counties, at a time when the winter 

 weather made it a matter of great difficulty. 



Mr. Isaac G. Perry, State Commissioner of Public Buildings, deserves 

 public recognition for his interest and ability in supplying a very hand- 

 some design for the New York State Mining Pavilion. 



Economic and Geologic Map. 



Since the preceding administrative report was written, the superin- 

 tendent of the scientiiic exhibit has been requested to amplify the report 

 on the economic minerals of New York and to prepare a map to illustrate 

 the distribution of the same. As only a few weeks' time is available 

 for the amplification of the report and the preparation of the map, the 

 writer has considered it best to give the most attention to the, map 

 and to outline very briefly in the text what is at present known about 

 the mineral industries of New York, giving references to articles by 

 reliable authorities. With this in view the accompanying map has been 

 compiled. A geological base was necessary to the proper differentia- 

 tion of the formations which are of economic importance, and the work 

 of preparing this has brought to light serious deficiencies in the knowl-
