North-eastward from Quebra Dentes, no explorations have been 
made for coal, so far as could lb? learned, but in ascending the new 
road which leaves Rio Itajahy doSulat the 115th kilometer and passes 
up on to the mountain, the Tubaréo series comes down between the 
120th and 122nd kilometer from Florianopolis. In these rocks the 
blossom of acoal is visible near the122nd kitometer post. The series 
consists of gray shales and massive, grayishwhite sandstones, some of 
which are conglomeritic. 
Coal has also been reported as cropping on one of the streams 
which put into Rio Iguassti from the south between Porto da Unido 
and the town of Rio Negro. 
In the region of Teixeira Soares,state of Paranda, some exploitations 
have been made for coal by Col. Macedo, of Curityba, and others. One of 
these localities is 3 kilometers west from the railway station of Tei- 
xeira Soares and about 45 meters lower where the following section is 
exposed :

The coal comes in thin layers in the black slate and much pyrites 
accompanies the same. 
About 3 kilometers N. 30° W. from tbe last locality, a thin crop- 
ping of cval is visible in a ravine known as Jacusinho, where the follo- 
wing succession is exposed :

This is the same coal horizon as that at the first locality, and it also 
contains a large quantity of pyrites. It is 15 meters lower than the other 
locality. 
At about one kilometer S. 10° W. from Teixeira Soares and 90 
meters lower, a thin (6 centimeters) coaly slate crops on the land of 
sr. Antonio Fogaca. The exposure is poor, and the position of the coal 
layer could only be determined approximately owing toa small land- 
slide near the horizon of the outcrop. Its position, however, is so far
