Auburn 



Auburn is on the Upper Helderberg limestone, and the 

 quarries which have been opened in this formation have 

 furnished a large amount of building material to the city ; 

 and the percentage of stone construction in the city is un- 

 usually high. The blue limestone is put in rubble-work and 

 in common walls and foundations ; the gray limestone is 

 used for dimension work and for curbing, gutter-stone, plat- 

 forms and house-trimmings. The Cayuga county court- 

 house is one of the old structures built of limestone. Its 

 walls are discolored slightly by iron stains, resulting from 

 the decomposition of pyrite in the stone. The city hall is 

 of blue limestone. The state prison and its inclosing walls 

 are of gray limestone. The First Presbyterian church, built 

 in 1870, and the First Baptist church, in 1883, are beautiful 

 examples of the gray limestone, in rock-face ashlar work, 

 with ax-hammered and bush-hammered limestone trimmings. 

 The rock-face and the ax-hammered and bush-hammered 

 surfaces, when thus brought together, produce a pleasing 

 effect by their not too great contrast in shades of color, 

 varying from dark to light-gray. 



Other notable buildings of limestone are : St. Peter's 

 Protestant Episcopal church, St. Mary's Roman Catholic
