undulated or concentric. I include under this variety, the Agaric mineral of Cleaveland and 
other authors, as also the Oolite of mineralogists. 
LOCALITIES. 
Albany County. In the caverns which occur in the towns of Bethlehem and Knox, and 
which have been already noticed, stalactites and stalagmites, together with the variety often 
known by the name of Calcareous sinter, abound. These are often susceptible of a good 
polish. On the Patroon’s creek, near the city, incrustations of carbonate of lime are also 
found, arising from the depositions of water charged with this mineral. 
Allegany County. There are several beds of calcareous tufa about a mile and a half east 
of Portage ; and two others have been observed near Rogers’ bridge, but they are of incon¬ 
siderable extent. 
In my notice of the localities of marl (page 83 et seq.), I omitted to state that two deposits 
occur in the town of Rushford ; one overlying a swamp on the land of Judge McCall; the 
other near the road. There is also a small deposit at Caneadea, a little above the level of the 
valley. It is said, however, that it has not been used at either of these places for the manu¬ 
facture of lime.* 
Columbia County. In the rivulet which flows from the spring at New-Lebanon, there is 
deposited a calcareous substance of a botryoidal and reniform shape, which, if collected from 
a place where it has been undisturbed for a considerable time, resembles a stalagmite. Cal¬ 
careous tufa is frequently met with in the limestone regions of this county. The spring 
which supplies the city of Hudson with water, is constantly depositing a calcareous tufa, 
which encloses sticks, reeds, helices, and in fact every substance with which it comes in 
contact. The deposit, however, is not extensive, and shows itself but little on the surface.! 
Dutchess County. Calcareous tufa is quite common in the limestone regions of this 
county. Stalactites, stalagmites, and concreted carbonate of lime of various forms, may be 
seen in the Spook hole, a cavern near Barnegat.| 
Erie County. Near Ellicott’s mills, there is a large deposit of calcareous tufa. Many 
tons of this newly formed rock are now suspended beneath the layers of the calciferous slate, 
and its volume is said to be constantly increasing by successive deposits. 
Franklin County. About two miles from Chateaugay four corners, near the base of the 
high banks of sandstone between which the Chateaugay river flows, there is a large mass of 
calcareous tufa, which seems to have been deposited from a small brook running across its 
bed. It is used in the vicinity as a building material, and also in the manufacture of lime. 
The deposit is of considerable extent. 
Greene County. On the Catskilland Canajoharie railroad, and near Catskill village, there 
are extensive deposits of calcareous tufa, which are formed by streams issuing from caverns 
in the limestone hills in the vicinity. Sometimes the limestone is covered with a thin and 
friable crust, which resembles the agaric mineral.
