Cor. Lucas gave me the following for the composition of two spe- 
cimens of coal from Serro Partido as determined in the laboratory of 
the Lyceu Riograndense at Pelotas:

The Treviso coal 
In the summit of the hills along the Estrada Nova, 4 1/2 kilometers 
north-west from Minas, Santa Catharina, and at 342.4 meters above sea 
level, there occurs the outcrop of a small coal bed. It appears to be 
above the horizon of the Barro Branco seam which crops at the turn of 
the road a kilometer eastward. It exhibits the following structure as 
measured by Dr. Seixas:

This may possibly be the Barro Branco coal, but since the later’s 
elevation (338.2) a mile eastward is 4.2 meters less than the supposed 
Treviso bed, Dr. Seixas, under whase supervision the elevations were 
taken, considers the coals distinct, although their structure is much 
the same. 
At Treviso, 30 kilometers south-west from Minas, thereis a bed of 
slaty coal which crops in the bank and bed of Rio Mae Luzia, and 
has been dug into in a shaft sunk from the,basement of Mr Bianchin’s 
mill near by. The coal issaveral feet in thickness, but contains 
much slaty material. This is the Trevl]so coal, and is the highest coal 
seam of the Rio Bonito beds. 
Rio Ferreiro puts into Rio Mae Luziaat Treviso from the south,and 
about one mile up this stream, the Treviso coal comes out to daylight
