The black slate and bony coal in the roof of the mine is filled with 
remains of Sigillaria, Lepidophioios and leaves of Lepidodendron. 
The upper division of the coal,n. 2, is generally better than the 
lower n. 5, since, although it appears to hold more sulphur, yet it has 
less slaty material than n. 5. Thecaracter of this coal as well as that 
in SantaCatharina and elsewhere is discussed in another chapter of 
this report. 
The light colered clay parting, n. 3, varies much in thickness in 
different portion of the mine, sometimes running up to 60 centi- 
meters or more, andagain thinning down to1. N. 4 contains much 
gocd coal, but it is so interstratified with black slate that it cannot be 
separated without crushing and washing. 
N. 5 alsocontains slaty and bony layers, but some of them can be 
eliminated in careful mining, though the coal will remain high in 
ash. 
Other measurements in different portions of the mine give the
