tion on the lake accessible by boats, are notable advantages. 

 One quarry only is now worked and that in a small way. 



Plattsburg, Clinton County. — In the vicinity of Plattsburg 

 there are several small quarries in the Chazy limestone which 

 furnish stone for construction in the town. The St. John's 

 Roman Catholic Church and the First Presbyterian Church are 

 , built of this stone. 



South of Plattsburg three and a half miles, the Burlington 

 Manufacturing Company has a quarry where a limestone is 

 obtained, which is known in the market as " Lepanto marble " 

 It is fine-crystalline in texture, gray to red in color, and takes a 

 high polish. The specific gravity is 2.709, and its weight per 

 cubic foot is 168.8 pounds. It contains 1.54 per cent, only of 

 matter insoluble in dilute hydrochloric acid and 94.87 per cent, 

 of calcium carbonate. The absorption test showed 0.145 per 

 cent, of water absorbed. In freezing and thawing there was no 

 change, but at a high heat the stone was fully calcined and 

 crumbled to the touch. 



The stone has to be hauled by teams to the lake, one mile east 

 of the quarry. It is dressed at the company's works in Burling- 

 ton, Vermont. 



The principal markets for it are Burlington and Plattsburg. 



Mohawk Valley. 



In Schenectady county there are two small quarries on the 

 south side of the Mohawk river, and near Pattersonville station, 

 which are worked at infrequent intervals for the local market. 

 They are in the horizon of the Trenton limestone. 



Amsterdam, Montgomery County. — The Birdseye limestone 

 and the Trenton limestone outcrops in the valley of the Chuc- 

 tanunda creek afford sites for quarrying building stone, and four 

 quarries have been opened north of the town of Amsterdam, 

 and at a height of 180 to 250 feet above the Mohawk valley. 

 The stone is in beds from six inches to three feet thick which are 

 almost horizontal. The rough stone is sold for making lime, 

 the best is cut into platforms, sills, lintels, and house-trimming 

 materials. The principal markets are Amsterdam, Albany, 

 Cohoes and Troy. Shanahan's quarry furnished a large amount
