Marl is a useful substitute for the hard limestones for some pur- 

 poses and is rather extensively developed in the central and western 

 parts of the State. It is found particularly in swampy tracts and 

 old lake basins associated with clay and peat. In the Cowaselon 

 swamp near Canastota the marl underlies several thousand acres 

 and is said to be 30 feet thick. The Montezuma marshes in Cayuga 

 and Seneca counties contain a large deposit which at Montezuma 

 is 14 feet thick. In Steuben county the marls at Arkport and Dans- 

 ville have been employed for lime-making. Until recently marls 

 have been used extensively for portland cement and plants were 

 operated at one time in the marl beds near Warner and Jordan, 

 Onondaga county; at Montezuma, Cayuga county; Wayland, Steu- 

 ben county ; and Caledonia, Livingston county. Their principal use 

 at present is for agricultural and chemical purposes. 



Production of limestone. The limestone quarried for various 

 uses constitutes more than one-half the total value of the quarry 

 products' of the State. The proportion would be even more in 

 favor of limestone if the stone consumed in portland cement manu- 

 facture was reckoned in the total, but that is excluded in order to 

 avoid duplication of the statistics. 



The reports submitted by the quarry companies indicate a very 

 large increase in the output for 1912, the total value of which 

 amounted to $3,510,445 against a value of $3,174,161 in 191 1. The 

 advance raised the figures above those for any previous year; the 

 next highest total was $3,300,383 in 1909. As in other branches of 

 the industry, no account has been made of the stone quarried by 

 contractors in connection with road improvement work, for which 

 it is impossible to secure reliable data.
