are several in Oswego, yield the same kind of sharp tasted salt, described 
as the salt petre taste, and all highly coloured with iron; characters dif- 
ferent from the salt of the brine springs which belong to a subsequent 
deposit, and show a difference of source or contamination from being de- 
posited with a different rock. 
Near Little Sodus bay there is another salt spring, which must arise 
from this rock. It is not far distant from the one described in the first 
report of this district. 
Gray Sandstone of Cayuga. 
To the south of the red sandstone, and reposing upon it, is a gray 
sandstone, the lower part often variegated with the red oxide of iron, 
and the upper variegated with green shale, resembling a coarse kind of 
''fret work." This mass for position corresponds with the mill stone 
grit" to the east, and the " gray band" to the west. It is quarried in 
two places. One quarry, owned by Mr. Bentley, on the road between 
Martville and Hannibalville; the other by Mr. Hulrae, and is between 
Little-Sodus creek and the line of Wa yne county. 
Protean Group. 
The gray sandstone is followed to the south by a series of green shales, 
with thin layers of sandstone with fucoids, with thin layers of fossilife- 
rous limestone used as firestones, and with the red oxide of iron, the well 
known products of the protean group. These products are best seen 
on Little Sodus creek, at Martville, and for about half a mile lower 
down the creek; also along the south shore of Oneida lake, commencing 
on the farm of Robert Bushnell, west of Joscelin corners; at the 
corners, and likewise at Oneida post-ofiice. From thence eastward, 
from being buried under the alluvial, or more probably washed away, 
they do not appear until near Verona, excepting on the land of Thomas 
Donnelly, on the road between Canastota and the State bridge. 
The iron, which is the same in kind with the Verona and Westmore- 
land ore, designated in the report of Dr. Beck as the " lenticular clay 
iron ore," is found in Cayuga to the south of Hulme's sandstone quarry, 
on the farm of Peter P. Van Patten. It occurs on and near the surface, 
fragments being often ploughed up. This bed seems to be the lower, 
or the Rochester mass, and not the one near the Wolcott furnace, which 
is the second mass. Iron ore of the same kind is said to be found in 
the creek near Martville, which I had not time to find, the locality 
being a secret. I have no doubt that it exists there, for the rock in the 
bed of the creek at the village, corresponds with the roof of the ore
