equivalents are perhaps the upper chazy and lower Trenton. These 
Trenton beds are exceedingly fossiliferous, the rock being in many 
places one mass of fossils. The most characteristic and abundant coral 
is Monticulipora lycoperdon. The brachiopods are best represented by 
Parastrophia hemiplicata, Phynchotrema copox, Raiinesquina alternata, 
Plectambonitcs scriceus and Strophomena rugosa (plaiutiiiboiiiim). 
Among trilobites the most characteristic are Trinucleiis concentricus, 
Isoteles (Asaphns) gigas and Calymene senaria. The Trenton out- 
crops are especially fossiliferous both north and south from Larrabee's 
point along the lake shore. 
The Utica shales, the highest palaeozoic strata here remaining, rest 
conformably upon the Trenton. In most places they are devoid of fos- 
sils as they are highly cleaved across the bedding; but on the lake 
shore about a half mile south of Larrabee's point in a cut made by the 
Rutland railroad the cleavage is not so marked. Here many specimens 
of Diplograptus pristis were found as well as one ipecimen each of 
Endoceras proteiforme and Triartlmis becliii. 
Wherever the surface, especially of the harder rocks, is exposed 
they are found to be glaciated. Upon this glaciated surface were de- 
posited the Champlain clays during the post-glacial subsidence. The 
basal beds contain very many concretions, in which, however, no fos- 
sils were found included, although much time was spent in looking for 
them. These beds and the later deposits still cover the valleys and 
plains, especially in the western half of the sheet, thus covering the 
palaeozoic outcrops. 
The entire region is very much faulted. One fault, for example, ex- 
tends from the swamp north of Sisson hill through the valley east of 
the hill, southward past the western edge of Barnum hill. West of the 
fault is Utica shale; east of it at Sisson hill is Beekmantown, at Barn- 
um hill the basal Beekmantown. The faults not only extend north and 
south but also east and west and indeed in almost every direction.
