Warden’s Salt Works. It was sunk in 1881. The Middle Kittanning 
seam has been very extensively worked on the Warden farm for many 
years to furnish fuel for the salt works. The lower coal was found less 
than 30 feet below the last-named seam. It is reported to have been 
4 feet and 9 inches thick. Judging from samples of the coal that were 
saved, the quality is excellent. The coal looks bright and hard and 
pure. The following analysis shows the composition of one of these 
fragments, and bears out fairly well the general judgment already ex- 
pressed. The analysis is fully up to the standard of the seam:

Robert R. Miller found the lower coal 28 feet below the upper seam 
(No. 6) on his farm. A valuable section, including another coal seam, 
is to be found here. It is as follows:

There is thus seen to be a deposit of the Lower Kittanning coal 
through a number of miles of the Will’s Creek Valley, that gives fair 
promise of economic value. It certainly deserves to be more thoroughly 
tested, for there is an apparent promise of a large field of good coal. 
THE Mippie Kitrannine Coan (Coax No. 6). 
This seam is confined within the same narrow limits which were 
assigned to the previously named seam. It is found above drainage in 
Guernsey county only in the deep valley of Will’s Creek, in Wheeling 
and Liberty townships, and to a very slight extent in Cambridge. The
