Another section taken from the face of the coal at the head of 
the main entry about 75 meters distant from the mouth of the 
mine, gives practically the same result as that shown above. 
The elevation ofthe bottom of the coal at Barro Branco Velho 
is 239.1 meters above sea level according to Dr. Seixas. 
About 200 meters south-east from Barro Branco Velho, and 
41.1 meters lower (228 m.), a coal has been explored under a cliff 
of sandstone (Upper Barro Branco) which appears to be identical 
‘with the Barro Branco coal. The section at this locality termed Barro 
Branco IIon the map is as follows:

The bottom coal has a fair appearance at this locality while 
the top member has thinned away very much. 
About one kilometer nearly due south from Barro Branco Velho 
is Carahd, 228 meters above sea level, where explorations were made 
for coal, several years ago. At the present time only 30 centimeters 
of coal can beseen, and the upper portion of thatis very pyritous. 
Dr. Gonzaga de Campos states that the coal is 50 centimeters 
in thickness, with a middle parting of slate, the upper half 
being purer, and prized by the smiths. Below the coal comes 
dark clay 70 centimeters thick and then hard sandstones, surrace de- 
posits conceal the top of the coal. 
A shaft was once sunk here and it is reported that at a coal 
3.80 meters in thickness was found at a depth of 28 meters. 
Tijuco Preto is a locality 200 meters south-east from Barro 
Branco Novo where a shallow shaft was once sunk for the Barro 
Branco coal. The following measurements were made in the old 
pit:
