Bright rich looking layers of coal 1/2 to 1 centimeter thick occur in 
the bituminous shale. Several galleries were driven into the hills here 
to explore the coal, but nothing valuable was discovered. 
On the fazenda of Mr. Joaquim Corréade Oliveira, 6 kilometers 
distant from Capellinha, another exploration was once made for coal at 
this same horizon. 
The outcrop there isalso a black shale in which are thin seams 
of coal under a massive ledge of conglomeritic sandstone 15 to 20 meters 
thick. 
Much bituminous shale lies about the surface which was taken 
from the galleries driven into the hills for coal, but the latter was found 
in only thin layers interstratified with the shale. 
Quality and fuel value of Brazilian coal 
Many analyses and reports on Brazilian coal have been published 
in the past. 
In most of these reports, the samples appear to have been selected 
from the purest portions of the coal beds in question instead of from 
average samples which would include the entire bad. By this method 
of sampling, very contradictory results were ecbtained when the same 
coals were submitted to test of actual commercial use. 
The analyses published led many people to hope that a purer coal 
would eventually be found in good quantity, something that would in 
its natural state displace Cardiff coal in Brazilian industry. 
The result of the work of the CoalCommission during the year 1904 
(which was fully confirmed by the further studies in 1905-6) was 
to abandon hope of finding beds of pure coal of explorable thickness in 
Brazil, since it was only too apparent at every outcrop and exploitation 
visited that the coal was everywhere of practically the same quality ;
