THE QUARRY MATERIALS OF NEW YORK— GRANITE, 

 GNEISS, TRAP AND MARBLE 



BY 



D. H. NEWLAND 



INTRODUCTION 



This report is the partial fulfilment of a plan to describe the 

 quarry resources of the State from the present-day standpoint. It 

 was the original purpose to include in the report a description of 

 the sandstone and limestone quarries as well as those of the crystal- 

 line rocks. The task of collecting the information for a complete 

 report, however, would have involved a considerable delay in the 

 publication of the results of the first part of the investigation, which 

 covers the crystalline areas of the Adirondacks and southeastern 

 New York, and it was thought advisable to issue that part separately. 

 It is the hope of the writer that a second report on the stratified 

 rocks may be prepared within a reasonable time. 



The division of the subject into two sections as outlined follows 

 a natural line of demarcation in the geographical distribution of the 

 formations ; it likewise has a basis in scientific and economic con- 

 siderations so apparent as to need no emphasis in this place. 



The only description of the building stones of New York at all 

 complete that has been available hitherto is found in the two 

 bulletins by John C. Smock. The earlier 1 of these (1888) was of 

 preliminary character, mainly devoted to the description of indi- 

 vidual quarries. The second, 2 published in 1890, included most
