in tlie same direction, but are doubled into a series of anti- 
clinals. It appears probable, that after the deposition of the 
bed of sand and mud forming these rocks in the ancient 
Silurian Sea, they were elevated and subjected to violent 
lateral pressure, and after this, that there was a long period 
when the rocks so formed were again beneath the waves, 
and were ground down by attrition to their present nearly 
level surface. On this, the coral reefs and shell beds forming 
the great mass of the Mountain Limestone was gradually 
accumulated. In many instances, there is between the two 
series of strata, a layer of pebbles derived from the Silurian 
Rocks beneath, and rounded by the action of water until 
all the sharp edges are worn off. Such a mass of pebbly 
conglomerate may be observed in the section photographed 
at the point where the water is thrown out, forming a pretty 
cascade. This conglomerate has been described as a detached 
mass of Old Red Sandstone, but the probability is that it 
must be considered as a part of the Carboniferous Limestone 
series, constituting a good dividing line between these and 
the Silurians, or as a basement bed to the Limestone.
