the Barro Branco bed, this one would problaby come near the horizon 
of the Bonito seam. 
Still farther north at Cedro on the land of Col. Macedo, near Im- 
hituva, acoal occupying the horizon of the Barro Branco bed has been 
explored to a considerable extent by Dr. Oliveira, first Engineer of the 
Coal Commission. At one of these localities the following section was 
observed :

Under this a shaft and boring were made toa depth of morethan 
100 meters, but no more coal was found, while above it, at 25 meters, 
comes a coarse conglomerate, and then the shales, and soft measures of 
the Palermo Beds. Hence, while it is not certain, it is quite possible 
that the coal at Cedro represents the Barro Branco seam. 
The composition of the coal at Cedro is shown by the following 
analysis made in Prof. Histe’s laboratory :

The quantity of sulphur is very large in’ the specimen taken, 
but would probably not average so much in general use. 
This is probably the same bed of coal that has been explored 
along asmall stream, one kilometer and a half south-\est from the 
village of Imbituva, where the good coal is only 8 to 10 centimeters 
thick with 60 centimeters or more of black slate below, in which are 
thin streaks of coal. 
Many leagues nort-eastward from Imbituva, there are several 
outcrops of coal along the waters of Rio Tibagy about 60 kilometers 
north from the town of the same name. The first outcrop makes its
