 several beds have been uncovered. 



In Wyoming county the bottom of Silver lake is said to consist 

 in part of marl. 



In Chautauqua county Cassadaga lake and the bordering marshes 

 contain marl. Both poftland cement and lime have been made 

 from the material, but these uses have long since been discontinued. 

 Tufa and marl occur at the southern end of Chautauqua lake. 



The following localities have been mentioned in different reports 



as having marl deposits, although little is known about the extent 



of the different beds. Along Tonawanda creek and near Lockport, 



Niagara county; Clarendon, Orleans county; near Lodi, Seneca 



county; Beaver Dams, Schuyler county; Cortland, Cortland county; 



Horseheads and Millport, Chemung county; Canajoharie, Fort

Otsego county; 4 miles south of Kinderhook, Columbia county; 



town of New Baltimore, Greene county; and towns of Rhinebeck, 



Northeast, Amenia, Pine Plains, Stanford and Red Hook, Dutchess 



county. A deposit in Round pond near Sharon Station, Dutchess 



county, was worked a few years ago, and other occurrences in this 



section have been exploited at different times for the supply of 



a icultural lime.
