At the former locality there are two quarries just north of the 

 to^vn and close to the Clinton and Bingham ton railroad. Both 

 are owned bj the Putnam estate, and the upper quarry (pi. 50), 

 or that nearest the town, is used for lime, while the lower one is 

 worked partly for road metal and partly for flux used at the 

 Franklin furnace near Clinton. 



The following analysis represents the average of samples taken 



from the lime quarry.

Onondaga county^ 



Some of the largest limestone quarries in ^ew York state are 

 situated in Onondaga county. The limestones quarried are the 

 Niagara, Lower Llelderberg and Tipper Helderberg. The purest 

 limestone in the county is furnished by the Stromatopora beds 

 and known as the ^' diamond blue " rock. Much stone of good 

 grade is however also furnished by the Lower Helderberg rock, 

 notably west of Syracuse. 



The Niagara limestone is exposed at several places from the 

 northwest corner of the county to Bridgeport. It generally 

 forms a low ridge. At Diedrich's quarry in Lysander village^ 

 where it has been operated for a number of years, the magnesian 

 Niagara limestone is 5 feet thick and of dark gray color. Near 

 Baldwinsville it is 4 feet thick but rather shaly. In Cicero it 

 is 3 feet thick and was formerly used for making lime. As a rule 

 the Niagara limestone can be easily quarried.
