PREFACE 



The following bulletin on the salt and gypsum industries 

 of New York State is published in accordance with the law 

 of 1892 relating to the appropriation for the geological map. 

 As its preparation has been somewhat hurried in order to 

 ensure its appearance during the legislative session of 1893, 

 it has not attained that fulness of detail, and perfection of 

 literary finish which was originally hoped for by the author. 

 He trusts, however, to be able to remedy any errors or 

 omissions in a subsequent edition which may be prepared 

 more at leisure. The purpose of this bulletin is not merely 

 to publish such new information as can be gathered, but to 

 give in concise form what has previously been made public. 

 Therefore r in order to make the report as reliable as possi- 

 ble, the most authentic sources of information have been 

 drawn upon. In this connection grateful acknowledgments 

 are made to Prof. I. P. Bishop for well records and statistical 

 information and for several photographic views of salt works. 

 Dr F. E. Englehardt has supplied the author with data of 

 varied character and a detailed article illustrated by draw- 

 ings, on the manufacture of salt in the State of New York. 

 To Prof. James Hall, State Geologist, the writer is indebted 

 for valuable information and advice. 



In the field the author's personal observations have been 

 supplemented by those of Messrs William C. Clarke, E. M., 

 and R. D. White, C. E., who, in the course of their duties in 

 collecting material for the World's Columbian Exposition, 

 have obtained measurements of the altitudes of the salt
