MARL. 87 



St. Lawrence County. We are informed by Dr. Emmons, ihal there is a deposit of 

 fresh water marl, containing shells, in the town of Edwards. Its location is among the gra- 

 nitic and limestone moimtains of this region, upon the soil of which this marl would be highly 

 beneficial.* 



Saratoga County. It is stated that marl underlies almost the whole sandy alluvion which 

 is here so widely diffused. In Schoharie County, although I am not aware that any deposits 

 of marl have been made known, there is abundance of calcareous tufa, and a friable agaric 

 mineral, which might be advantageously employed for the same purposes. The agaric mineral 

 has the following composition ; 



Carbonate of lime, 97.25 



, • Silica, 0.80 



Organic matter, 1.95 



It would answer well for burning into lime. 



Seneca County. Several beds of marl have been found in this county. One of these is 

 in tlie north part of Varick ; and there are several near the viUage of Ovid. It has been used 

 here to a hmited extent, both for burning into lime, and for agricultural purposes. 



In Steuben County, about four miles north of Bath, there is an extensive deposit of marl 

 and tufa, the results of repeated depositions from a copious spring. The marl is said to be 

 largely mixed with clav, but it is thought to be sufficiently pure for agi-icultural purposes. 



Tioga County contains at least one bed of marl, at the bottom of a pond m the town of 

 Spencer. 



Tompkins County. Several valuable deposits of this mineral are already here made known. 

 Thus there is a very extensive one in the southern part of Hector, which embraces an area of 

 six acres ; also at Reynoldsville there are several beds, from one of which two thousand bu- 

 shels of lime are burned annually.! Again, there are several beds on the land of Mr. A. 

 Wood, six miles from Ithaca, and others occur near Newfield. 



There are several localities of marl in Ulster County. Some of them contain fossil bones. 

 The following are the results of an analysis of a specimen from the neighbourhood of the vil- 

 lage of Kingston, viz : 



• Carbonate of lime, 92.75 



Silica and ahmiina, 3. 25 



Vegetable matter, 4. 00 



It perhaps should be stated here, that there is in the vicinity of the High falls a .5oft argil- 

 laceous limestone, which, as it may be easily reduced to powder, has been j)roposed as a
