_ The first of the list outweighs and overshadows all the rest so far 
that no great injustice would be done if all but this seam were omitted 
in our review. 
The coals of the valley of Big Sandy have already been described 
under the preceding section. It is here that the only field of the county 
is found in which the Kittanning coals have any value. The state- 
ments previously made express the facts as to the quantity, quality, and 
conditions of these seams throughout those portions of Rose and Brown 
townships that are traversed by the valley. The same seams can be 
followed under like conditions up the Connotton Valley, but they barely 
enter Carroll county above drainage. ‘The facts in this connection have 
already been given on pages 77 and 78 of chapter I, and no further 
statements in regard to these seams are called for here. 
The Freeport horizon is co-extensive with the limits of the county. 
It hes high in the hills in Rose and Brown townships, and it is but 
occasionally reached, and then only in the deepest valleys, in Lee, 
Loudon and Perry townships, ia the southeastern corner of the county, 
but there is the best of reason for believing that it extends through all 
of this region, even where it does not come to light in the valleys. 
This reason is found in the fact that as soon as the proper level is 
reached by following downwards any of these valleys, the series 
promptly appears. The place of the Freeport Group is also deeply
