In Nos. 2 and 3 there is a ourth bench of coal. This is to be seen 
everywhere in the lower part of the Snow Fork valley, where the seam 
is in its complete or normal state. In come places not only is this top 
coal gone, but the bituminous shale below it, both being replaced by sand- 
rock. 
No mines have been opened on Snow Fork so far as I know, except thos 
recently opened at the Ogden and Akron furnaces. At the former the 
top coal and shale are replaced by sand-rock, and the coal is probably less 
good than will be obtained under better cover. The Ogden Furnace is 
an exceedingly perfect one in all its equipments, and is worthy to be fed 
with the very best fuel the Snow Fork valley affords.

low shales. The upper or fourth bench, with the bituminous shale under
