STONE 



The quarrying of stone and its preparation for the varied require- 

 ments of building, engineering construction, etc., hold a prominent 

 place in the industrial activities of the State. For many years the 

 value of the annual product ranked second only to that of clay among, 

 mineral materials. No other industry includes so many individual 

 enterprises or is as widely represented in the diiierent sections. 

 The resources are notably abundant and in variety are scarcely 

 excelled by those of any other State; practically every kind of 

 building stone known to the trade occurs in quantity if not actually 

 an object of quarry operations. 



From the present commercial standpoint the most important 

 of the quarry stones are the limestones and sandstones which supply 

 material chiefly for engineering work, highway improvement and 

 such purposes that do not entail any considerable amount of 

 elaboration previous to shipment. In general these resources are 

 developed to the full market requirements. On the other hand, 

 in the building, monumental and ornamental branches the local 

 industry has not attained the importance relatively that it deserves 

 by reason of the natural wealth of materials adapted to those uses 

 and the local market needs. Herein, undoubtedly, lies the principal 

 field for future enterprise. 



The statistics of production which have been collected from year 

 to year show that the industry in general remains practically 

 stationary; in fact lately it has shown rather a downward trend, 

 falling below the average level of earlier years. This has been due 

 largely to the change that has taken place in the methods of building 

 and engineering construction. The use of cement and terra cotta 

 has displaced cut stone to a considerable extent in building operations, 

 while the increasing favor shown for concrete in municipal improve-
