few feel of a green grit like that of Flint Hill. The black shales crop out at several 
points along the road south, and also on the ridge east of it. These are classed in 
(D) and the quartzite in (E) of the table. 
Between this line of quarries and the road running south the Olive grits (A) crop 
out at several points and extend to the road corner north — all with an easterly dip. 
Idic first quarry on the west side of the north and south road shows a very gentle 
syncline at its south end and the beginning of an anticline at its northeast corner. 
The next line of quarries west include- the Eagle. The strike here changes to X. 15°- 
20°-30°-40° W. The dips are 25°-30° E. and SE. The cleavage strikes N. 5° E. 
and dips 20° E. There are about 70 feet of purple, overlain by 10 feet of green and 
these by 15 feet of thin-bedded Olenellus limestone. At the most northerly quarry 
but one of this line the beds are folded and overturned almost as much as at Cedar 
Point I see fig. 0, PI. KXIV . The strike of axis of fold is N. 40° W.; cleavage dip, 
low, east. Small beds of light green, with or without a quartzose limestone in the 
center, produce band.- on the cleavage surface. 
At a quarry intermediate between the second and third lines of quarries, and one- 
fourth of a mile north of this section, the strike changes to X. 75° W., dip 15°-20° S.;l 
cleavage strike, X. 35°-50° E., dip 15° E. The complication is probably due to a 
southerly pitch. 
In the third line of quarries the beds are nearly horizontal. The fourth line, a 
half mile south of section, show- very low westerly dips and at the extreme west 
end of tin- section a gentle syncline is exposed crossed by a cleavage dipping 35° E.

This starts at the wesl shore of LakeSt. Catherine and crosses the slate ridge west. 
Tin- portion of the slate belt mosl largely worked of late years is the ridge between 
YVe-t Pawlet and Poultney. Away from the quarries it i.- difficult to obtain satisfac- 
tory observations, and w ithin the quarries bedding is generally obscured by cleavage.'; 
Beginning a1 the lake, purple and green ( Jambrian slates dip 45° E. Judging from 
scattering observations along the west side of the ridge, it must be largely composed 
of roofing slam. From a point about a half mile west of the lake there is a line of 
quarries and prospect holt- extending northward for 2 miles. The cleavage dip is 
uniformly east. Farther west the section crosses a strip of redOrdovician slate almost 
a half a mile long and 180 feel wide at the broadest part, but tapering out both north 
and south. The dip is 35 c ]•;. This is probably a small compressed and overturned 
syncline. The Ordovician grit is absent here, but some of the small quartzite becfl 
occur between the< Jambrian slates and the red slates. All the slate.- exposed between 
the strip of red and the road on the west should recur on the east of the red, but 
in inverse order. At AuM & Conger's quarries then- are L70 feet of slate of various 
qualities, green and variegated, exposed. Strike X. 5° W., dip 35° E., with cleavage 
dipping 40°-45° E. Pipping toward and under the slate, but with greenish and gray- 
i-h beds intervening, are the Hudson grits. Strike X. •"> K.. dip 40° E. Between the 
syncline of red slate and the Hudson grits there i- probably an anticline, as drawn id 
■tion. and all tin- slates on the west side of the red ought to recur east of the 
grits in inverse order. The folds shown in the grit are hypothetical, but thefirsl one 
west of the slate would naturally be a syncline. 
SECTION vi. — PAWLET. 
This beginsnear the Mettawee and crosses the slate ridge. The boundary between 
Ordovician and ( iambrian at the east end of the section is uncertain. In the gorge of 
the Mettawee green and purple Cambrian slates of no commercial value are nnelj 
exposed. At the sawmill the axial planes of the folds stand erect, and the anticlinal 
part- of some of the folds have been pinched out. The cleavage is vertical. The
