PREFACE 



The following report on the limestones of l^ew York state 

 deals with their uses in the various industries, but does not in- 

 clude the use of limestone for building or road construction. 



It is hoped that it may serve two purposes : 



1 To give information to quarry owners concerning the uses 

 of limestone and the characters which the stone should possess, 

 to make it of value for these different applications. 



2 To supply limestone consumers with information regarding 

 the extent and character of the limestone formations of ISTew 

 York. 



Many quarries have been visited, and samples collected for 

 analvsis ; and, while the chemical work has not been carried out 

 in as much detail as might have been desired, still it is hoped 

 that the analyses given may serve to prevent useless search in 

 unpromising localities. In the preparation of that portion of 

 the report relating to the testing and manufacture of cement the 

 writer has drawn freely on many of the works referred to in the 

 body of the report. 



The writer wishes to express his thanks to the many quarry 



owners who have extended courtesies to him during the course 



of the work, and also to Dr F. J. H. Merrill, state geologist, for 



many valuable suggestions.
