BULLETIN OF THE 
2 BED-ROCKS OF THE REGION, 
CANAAN AND LEBANON RANGE AND SHAKER VALLEY. 
Along the western slope of the Canaan and Lebanon Range, the 
exposures of bed-rock consist of fine-grained mica schist, containing, in 
some localities, layers of white quartz from one fourth of an inch to one 
inch in thickness. 
Upon the knob called Fry’s Hill, on the crest of the Canaan and 
Lebanon Range, are exposures of fine-grained, foliaceous rock, very 
tough, and of a green color. It is a chloritic, probably metamorphic rock, 
and closely-resembles that of which the Richmond Boulder Trains are 
composed. This rock is very limited in extent, being found, with one 
exception, only wpon Fry's Hill, and in that locality not extending more 
than 150 feet below the summit. Its lack of stratification, its peculiar 
structure and limited extent secm to indicate that it may have been 
originally an igneous rock, but no direct junction of it with other rocks 
was found. In order to more fully determine its nature, thin sections 
were studied by Mr. Wadsworth, who considers it to be a chloritic 
schist.* 
Just west of the summit of Douglas Knob, one and one fourth miles 
N. N. E. from Fry’s Hill, the bed-rock is similar to that of the latter 
locality, except that it shows signs of stratification, and contains rounded 
grains of quartz, so that it is, in all probability, a metamorphosed, 
argillaceous sandstone. On the same range, a summit half a mile 
S. 5. W. from Fry's Hill is made up of rock which closely resembles 
that just described as occurring at Douglas Knob. 
Along the eastern slope of the Canaan and Lebanon Range the bed- 
rock is a friable and micaceous argillite, the exposures near the crest, of 
the range being greenish gray, while those near the base are dark gray 
or nearly black. 
Through the bottom of the Shaker Valley extends a broad belt of 
well-stratified highly crystalline limestone, containing no traces of fos- 
sils. This rock is mottled gray and white upon the fresh surface, but 
white when weathered. 
RICHMOND RANGE AND RIOHMOND VALLEY. 
Upon the western slope of the Richmond Range, the rock is a fine- 
grained mica schist, in many places approaching argillite. Near the 
* A more detailed account of the results of Mr. Wadsworth’s microscopic analysis of 
this and other rocks of the region is contained in note D, page 39.
