other; these are used for water vessels, &c. the concavity being often so 
great as to contain several gallons. 
In the vaVey of Cayuta creek the group is exposed in a ravine three 
mile5 north of Factory ville, where fine flag stones could easily be obtained . 
In the north part of Barton are great numbers of loose masses contain- 
ing the fossils of this group, probably washed down from the tops of 
the hills in the vicinity. 
A group so characteristic and so well defined in the valley, and par- 
ticularly in the town of Chemung, merits the appellation of the Che- 
mung group. 
The topography of this county is very simple; the Chemung river 
passes through the southwestern part of the county, and opens a broad 
and beautiful valley, bounded by a range of hills which are only broken 
by the lateral streams flowing to the river; the rocks on one side some- 
times approach the river, while on the opposite is an extensive flat or 
bottom. Here, as elsewhere, the rocks on both sides of the valley bear 
evidence of erosion, and show that this river, as well as other streams, 
flows in a bed once occupied by rocks like those of the mountain mass. 
The eastern boundary of the county is along the valley of Cayuta 
creek, which has its origin in the small Cayuta lake, in the north part 
of the county, and forms a continuous valley thence to the Chemung 
river. Wynkoop's and Baldwin's creek form valleys of less impor- 
tance. 
The Chemung valley, extending from the head of Seneca lake to the 
Chemung river, is the most prominent feature in the county. It offers 
the only route by which a canal could have been constructed, being 
through its whole extent alluvial, and presenting no remarkable eleva- 
tions. The ascent from Seneca lake to the summit level of this canal, 
is 440 feet in a distance of fifteen miles. 
STEUBEN COUNTY. 
The examinations in Steuben county during the past season, were 
principally confined to the eastern and southern part, along the val- 
leys of the Chemung, Canisteo and Conhocton rivers, the valley of 
Crooked lake, &c.; and beyond this, some other points of interest, with 
one or two reputed localities of coal, which prove like all others of the 
same kmd, a fruitless enterprise.
