16 Oolitic formation ra Saratoga County. 
Arr. UL.—A grace of the Oolitic Form ois itely 
discovered in the county of Saratoga, and state of New- 
ork ; chesnagaaned by Dr. Jonn H. Steere. 
Berna, about a year ago, in the shop of Mr. Lyman B. 
Langworthy, an ingenious mechanic at Ballston-Spa, he 
shewed me a small specimen which was evidently Oolite ; 
he was unable, however, to designate the spot from whence 
it came, but believed that it had been found in the vicini ity 
of that place. Some time after, a farmer brought en 
specimen, as large as a man’s hand, which he said he had 
picked up on his farm, and that it contained “petri 
tard-seed.” 1 was, until recently, unable to ak 
_ the place of its origin. Being in company with Dr. Childs, 
- an intelligent physician, in the neighbouring town o Mil- 
ton, he informed me that the formation in pate occur- 
_ red on the farm of Mr. Benjamin Rose, an an uncle of his, in 
the town of Greenfield. I soon after visited the place, and 
the an situ in severa 
nt “3 see I have sub- 
y been able to trace its connection, in different pla- 
. ees, for several i in nearly an east an nd west direction, 
: the southern line of the town—its extent north and 
south i is probably not so great. 
The easternmost point, where this formation discovers 
itself, is about two miles from the village of Saratoga 
mountain; from this spot it stretches across the valley 
which separates the Palmertown from the Kayadarosseras 
mountain, and probably may yet be traced around the ter- 
mination of the latter mountain, to that of the Sacandaga, 
“ possibly, along the whole extent of these primitive 
rs of what professor Eaton calls “ the McComb’s moun- 
tains.””* 
* Professor Eaton, to whom i gave a — of the Oolite here de- 
scribed says, “There is nothing analogous to it in eats secondary forma- 
tion of the Canal district, west of Utic a, a; ioueeh some of the western rocks, 
which lie above _ iron formation, resemble the fb ‘urope: an rocks which 
are there contiguous to the Oolite. Butl think the Oolite may yet be 
found in connection ; wile hat I have calle etween the 
spurs of gneiss, which extend down from the goneipete 3 mountains.
