GEOLOGY OF THE THIRD DISTRICT. 
The above section exhibits the raised masses of rock which form the uplift of Little-Falls, 
exhibiting the same series on both sides of the river gap, being at right angles to the direction 
of the gap. In ascending the river, these rocks in succession appear at the level of the canal, 
and then disappear; no further trace thence being visible, with the exception of the Utica slate, 
which continues to form the base or bottom of the valley to the west of Utica. 
The slate is visible at the east end of the gap, on the north side, not far from the toll-house ; 
it is there flat. It shows itself in several places, inclining from the primary and the calci- 
ferous, according to the distance from the junction of the two : the lowest angle observed was 
about thirty degrees. 
The same observations were made on the south side, where the slate also appears in the 
small brooks which come from the uplift, and which show a high inclination from the uplift. 
Though obscure from rubbish and soil which have collected along the wall of the uplift, the 
disturbed position and inclination of the slate is sufficiently obvious ; its usual position, when 
a little removed from the upraised masses, being flat or nearly horizontal. The upraised slate, 
as it exists on examination, at the east end of the uplift, would have been exhibited in the 
engraving were it not intended to give what was obvious without examination. 
There are two other uplifts of a local character worthy of note, one on West and the other 
on East-Canada creek : that of West-Canada is at Middleville. It shows the whole series 
from the primary upwards. It is the last point to the west and north, where the primary is 
seen out of its range, or the calciferous appears to the west. 
The primary rock is seen in the creek above the mill-dam at the village, and by the road¬ 
side on the left ascending bank. The calciferous forms a thick mass, appearing at a high 
level on both sides of the creek, and is followed by the birdseye and the Trenton limestone, 
and the slate.

The uplift on East-Canada creek is of greater interest, being one of the finest displays of 
curvature from uplift yet seen or known to have been recorded. There no soil or rubbish 
obstructs the view of the whole length of the upraised slate, which extends in one broad 
unbroken sheet by the side of the creek for more than a quarter of a mile. Where it ends, 
going down the creek, the Trenton limestone appears from beneath, curving also in the same 
direction with the slate. This uplift is below the high falls, about a mile and a quarter
