Intermediate sections at Butia, S. Sepé, Suspiro, and other points 
in Rio Grande do Sul; confirm the evidence of these sections just given 
namely, that the coal-bearing series of rocks, with the single exception 
of the Minas region in Santa Catharina, hold but one important coal 
seam, and that is near the top of the Rio Bonito beds. The same stale 
of affairs appears to exist also at all localitiesin Parand, and S. Paulo 
where coal occurs. 
Butia is about 30 kilometers south-west from the town of S. Jero- 
nymo, and there the same coal mined on Arroio dos Ratos has been 
explored to a small extent on the waters of Sanga da Mina. Here 
it exhibits the following section in a ravine, near where an old shaft 
was sunk through the coal under the supervision of Mr. Eugenio

This coal has heen exploited at several points between Butia and 
Rio Jrapud and it appears to havea triple structure in all. 
Near the home of Dr. Barcellos, on Rio Irapud, another section west
