Quarries for furnishing crushed stone have been opened at 

 Little Falls where there is an extensive intrusion of the Adiron- 

 dack syenite. The crushing plant of the John Pierce Co. on the 

 north side of the Mohawk river is the largest in the State, and 

 produces road metal, railroad ballast and concrete material. 

 Another quarry on the south side of the river has recently been 

 equipped with a plant for making concrete blocks. The quarries 

 are advantageously situated for shipment of their product both 

 by railroad and the canal. system of the State and should com- 

 mand a wide market. 



The Picton Island Red Granite Co. has been engaged in quar- 

 rying on Picton island in the St Lawrence river. The stone is 

 a biotite granite, ranging from medium to fine in texture, and 

 has a very attractive reddish color, verging toward pink in the 

 fine grained variety. Similar granites have been quarried in the 

 vicinity for many years and have gained a wide repute for their 

 beauty and durability. The present quarries have furnished build- 

 ing material chiefly, but the stone is well adapted for monumen- 

 tal and decorative work as well. It has a specific gravity of 

 2.653 ^^^ ^ crushing strength of 16,500 pounds to the square 

 inch. 



The Adirondack anorthosite affords in some places a gray or 

 bluish gray massive stone often showing the very pleasing effect 

 of a porphyry when polished. It has been quarried on a small 

 scale, principally for monumental purposes. The opening of new 

 quarries near Ausable Forks, Clinton co. is contemplated by 

 Mr Ernest Leblond who has also a quarry property in Adiron- 

 dack syenite in the same vicinity.
