very nearly with that of section 44 (Hastern Greylock). The 
synclinal character of the mountain, which is here sustained by 
my observations, was determined by the Vermont Geological 
Survey, one of whose sections passes through the mountain. 
An unpublished section by Prof. James Hall, made “about 
1845,” first described in 1854 {in this Journal, an engraved 
plate containing this among its sections having been sent by 
Mr. Hall to the writer) shows similar dips on the two sides. - 
‘Mt. Anthony is, like Greylock and Mt. Washington, one of the 
more elevated summits of the Taconic range, the height being 
2,606 feet. Mr. Hall’s plate of sections also includes one of 
Mt. Washington, and sustains the synclinal character of this 
mountain. Itisafurther interesting fact that Mt. Anthony 
has on its north and east sides a similar high limestone base- 
ment; its height is about 400 feet by estimate above the val- 
ley at its east base. 
Sb Berlin, N.Y.; Eastiofrivers ~ 50, N.W. f't of Mt. Anthony, Bennington, 
Section 51. The locality of this section is in Berlin at the 
west side of the Taconic range; it shows the slate and limestone 
in alternations at their junction, with the bedding somewhat 
contorted. ‘The section conforms to all sections on the west 
side of the Taconic range in its eastward dip, and may be taken, 
with that at the western base of Mt. Washington, as a repre- 
sentative section. Other sections might be added from my 
note book from all parts of Berkshire; but the T-shaped sym- 
bols over the map make further additions unnecessary. 
4, Stratigraphic Conclusions. 
1. ZLaconic schists and the limestone in the western half of the 
limestone region.—From the sections through the higher points 
of the Taconic Mountains, Mt. Anthony, Greylock and Mt. 
Washington, the following conclusions are deduced. 
(1.) The flexures in these three parts of the Taconic range 
are synclinal. 
(2.) The limestone is the underlying rock. 
(3.) The limestone lying along the eastern and the western 
sides of the range are continuous underneath the mountains 
and therefore one in mass,—a fact already proved for the 
western limestones and the eastern, by their continuity of mass 
at the surface. It follows, consequently, that—
