All of the limestone used by the Solvay Process Co., of Syracuse, in the 

 manufacture of soda-ash, amounting to more than 250,000 tons annually, is 

 taken from "blue lime" beds in the large quarry operated by the company at 

 Split Rock, about five miles southwest from Syracuse. 



Very little blasting powder is required in quarrying these l teds for 

 building stone. In the flexing and tilting to which they have been subjected, 

 they have been much shattered, owing to their rigid, brittle character, so that 

 vertical cracks, joints and crevices are very frequent. By the use of heavj 

 pinch bars large blocks are dislodged. These are roughly reduced with 

 heavy hammers to such sizes and shapes as may be desired, then hauled to 

 their destination where the facing stone or ashlars are finished with chisels 

 and light hammers, the rest being laid into the wall without further dressing. 



During the century of occupancy of this region by white men, a very 

 Luge number of quarries have been opened along the line of outcrop of these 

 limestones, at first, to supply local demand in the building of the villages 

 w hich sprang into being when the Seneca turnpike was the great east and 

 west thoroughfare across the county, following very closely the brink of the 

 great escarpment. Some of them were abandoned, but a large number of 

 new ones, more conveniently situated in regard to transportation, were opened 

 w hen the building of the Erie canal and the railroads and the rapid grow th 

 of the city of Syracuse created a new and immense demand from another 

 direction.
