GEOLOGY OF CHILHOWEE MOUNTAIN, IN TENNESSEE. 79 
stone is very much thinner than in Millers cove, is not 
cherty, and does not follow an unconformity. The Rome 
sandstone, in its nearer outcrops, is less than half as thick 
as the Millers cove shale, is not cherty, and is much more 
sandy. The only other limestone, the middle Cambriali, 
is not followed by any red shale and hence does not furnish 
the same sequence. The dolomite, however, shows such a 
sequence wherever the shore was near at hand, in the cherty 
limestone and red shale following an unconformity. 
(e) It has been stated that no fossils have been seen in the 
Millers cove series. This paucity of life serves as an addi¬ 
tional distinction between the Cambrian beds and the Mil¬ 
lers cove rocks, because fossils can readily be found every¬ 
where in the Cambrian beds. The barrenness of the cove 
series is paralleled in the dolomite, which has scarcely a fossil 
except at the top and bottom. This evidence is negative, 
of course, but has some value, in that it corroborates other 
evidence. 
(/) To sum up, the following points of difference and 
resemblance appear between the Millers cove series and 
other beds: The Cove limestone and the Knox dolomite 
are the only cherty deposits before the Carboniferous. They 
have the only beds of white dolomitic limestone. They have 
limestone conglomerate beds, the mark of a special erosion 
condition. The Cove limestone is thicker than any except 
the Knox, and may be equally thick in full presentation. 
In the Cove limestone and Knox are developed the same 
phase of red cherty shale under similar shore conditions. 
They have the same sequence, and it is the only parallel one. 
They contain practically no organic remains, and are the 
only beds so specially marked. a 
These are indications of identity of Knox dolomite and 
Cove limestone. Opposed to them are the negative points, 
that the Cove limestone is not known to be as thick as the 
Knox, and that there are limestones and red shales other 
than Knox that might be equivalent to the Cove series. The 
first objection has been discussed and has small weight.
