114 Tne American Geologist. February, 1867 
E. Woltt', refers the Rutland iiuirble quarry, on which the vil- 
lage is built, to the "Elliptocephalus (Olenellus) zone," which 
he calls Lower Cambrian (Lower Taconic), instead of the 
upper part of the Middle Taconic (Middle Cambrian). In the 
absence of trilobites, or any other fossil characteristic and 
common at Georgia, the correlation of the Rutland marble 
with the Georgia formation is an hypothesis without a pahe- 
ontological basis. It belongs to the Taconic system, as Dr. 
Emmons says, and very likely to the lower part of the Phil- 
lipsburgh and Pointe Levis formation, that is to say, -to the 
base of the Upper Taconic, just above and in contact with the 
Georgia formation, 
Seco')ul, the marble quarries of Centre Rutland and West 
Rutland are referred to the Trenton-Chazy ('alciferous form- 
ation, a rather curious compound, which it is impossible to 
justify stratigraphi(;ally, or lithologicall}^, or even less pala^- 
ontologicallj^ for Mr. Wolff quotes only as fossil remains 
found there, a few crinoid stems. 
The author gives a sketch geological diagram of the vicin- 
ity of Rutland, showing plainly the peculiar stratigraph}'^ of 
large lenticular masses of limestone marble, inclosed in slates; 
just as at Shoreham and at Phillipsburgh, a stratigraphic fea- 
ture characteristic of the Taconic system, which has even not 
attracted the attention of Mr. Wollf, who does not notice it. 
The Green Mountains in Massachusetts. 
After many years of opposition to the Taconic system at its 
typical locality, the vicinity of Williamstown, Massachusetts, 
without a single particle of proof, a very elaborate memoir 
has been published at last, in 1895; it is entitled "Geology of 
the Green Mountains in Massachusetts," by Raphael Pum- 
pelly, J, E. Wolif and T. Nelson Dale, in Monographs of the 
U. 8. Geol. Snrv., vol. xxiii, Washington, 1894. In the pre- 
face, at p. xiii, Mr. Pumpelly sa3^s : "It has been our intention 
to keep wholly clear of the Taconic controversy and to confine 
our efforts to accurate study and interpretation of structure." 
Unhappily all his efforts break down from the first page, and 
throughout the memoir he has spoken constantly of Lower 
Silurian and Lower Cambrian, referring strata to those two 
systems of rocks without proper proofs of any sort and against 
all rules of stratigraphic classification. If the authors had
