lius, Elbridge and Van Buren townships. Onondaga and Cross 

 lakes contain deposits. Some localities afford very pure material, 

 yielding an excellent white lime when burned. The marls have 

 been employed to some extent for this purpose and for fertilizer, 

 but the principal application at present is in Portland cement manu- 

 facture. The Empire Portland Cement Co. works a deposit near 

 Warners, which is 6 to 7 feet thick and is underlain by blue clay. 

 The two substances are mixed and burned into cement. The Ameri- 

 can Portland Cement Co. owns marl lands near Jordan, but its plant 

 is not now in operation. 



The Montezuma marshes covering a large area north of Cayuga 

 lake in Cayuga and Seneca counties are reported to be underlain by 

 marl. At Montezuma a deposit 14 feet thick was opened by a cement 

 company which is now inactive. 



In Wayne county, the Cayuga marshes which occupy a part of 

 the town of Savannah contain a deposit of shell marl 5 to 6 feet 

 deep. Other beds occur near Newark and in Cooper's swamp, town 

 of Williamson. 



Steuben county possesses numerous deposits of marl and tufa. 

 According to Hall^ they have been used for lime burning at Ark- 

 port and south of Dansville. In the town of Wayland the Portland 

 cement works of Thomas Millen Co. and the Wayland Portland 

 Cement Co. employ marl which is obtained from local beds, ranging 

 from 2 to 14 feet thick. 



In the southern part of Monroe county there is a large deposit 

 which occupies a portion of the town of Wheatland and extends 

 south into Livingston county. Tufa forms the upper part at some 

 places, and beneath is shell marl, 3 to 4 feet thick.- Another 

 deposit is found along Mill creek, underlying extensive marshes. 

 At Mumford several beds have been found. 



In Livingston county the most important deposits occur near 

 Caledonia. The Iroquois Portland Cement Co. has recently erected 

 a plant at this locality. The Caledonia Marl & Lime Co. is engaged 

 in the production and preparation of marl for fertilizing and other 

 purposes. 



There are many marl swamps in Genesee county. An extensive 

 deposit occurs i mile west of Bergen. Around Leroy and Batavia 

 several beds have been located. 



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

 in part of marl.
