have furnished much stone. Sandstone from Nyack and 

 Haverstraw, and Connecticut brownstone also were much 

 used formerly. 



''Washington's Headquarters," built in 1750, is the oldest 

 stone building in the city. The walls are laid up with com- 

 mon field stone, mostly sandstones. Scarcely any signs of 

 weathering are noticeable in them. The St. George Prot- 

 estant Episcopal church is another old structure, of dressed 

 blue limestone with brownstone sills and water-tables. 

 The limestone has faded and is a gray-white in color, but 

 has not apparently lost in strength or durability. St. Pat- 

 rick's Roman Catholic church is another structure of lime- 

 stone, part of which is reported to have come from Kings- 

 ton quarries. Some of the blocks are weathered yellow, and 

 in some the clay seams appear prominent, although the 

 building is of comparatively recent date. The First Pres- 

 byterian church is a large and ornate edifice of a dark, slate- 

 colored sandstone, obtained from near Kingston. The 

 walls are of small stone, laid in broken courses and 

 trimmed with Ohio sandstone. There are no signs of dis- 

 integration in the wall stones. Of the buildings in part of 

 stone, the more notable are the Academy of Music (1887) 

 and the Newburgh academy, both of red brick and Massa- 

 chusetts red sandstone. Connecticut brownstone is seen in 

 the United States hotel, the post-office, and in many cases 

 as doorsteps and house-trimmings. Ohio sandstone ex- 

 amples are : the Newburgh city library and the savings bank 

 buildings. 



Streets. — The sidewalks are paved generally with blue- 

 stone from the Hudson river valley. The aggregate length 

 of paved sidewalks is about thirty miles. Cross-walks and 

 curbing also are of blue stone. 



The roadways are laid with stone to the following extent f^- 



Cobblestone pavement, two miles; granite-block pavement, four hundred 

 feet.
