just mentioned at many kilometers from any outcrop of granite 
rocks. 
One of these deposits, in which were counted 5 boulders 3 me-~ 
ters in diameter, was encountered near the 135th kilometer from 
Joinville. 
A great boulder deposit may also be seen just under the Coal 
Measures at many points in Rio Grande do Sul, notably near the 
mines of 8. Jeronymo, near Butid, as well as near S. Sepé, and at 
numerous other localities. 
In the State of Paranda, there is an enormous mass of gravel, 
large boulders, petrified wood, etc., resting unconformably upon 
shales holding Devonian fossils, in the vicinity of Ponta Grossa, 
and other places between there and Serrinha, especially between 
kilometer posts 115 and 125 from Curityba. It is also probably the 
same formation that makes the «Rock City) known as Villa Velha, 
on the summits several kilometers soutlt from Ponta Grossa. 
Dr. Derby reports the presence of great boulders of granite and 
other crystalline rocks in a similar unstratified paste or mud stone 
at many localities in the State of S. Paulo, so that, although no 
ice striae or scratched boulders have been observed in connection 
with this fossil moraine as in South Africa and India, vet there 
seems no reason to doubt that these deposits have had the same 
origin as the «Glacial» or «Dwyka» conglomerate of the african 
region. The writer has not visited the locality in Minas Geraes (Val- 
ley of Rio Borrachudo, a western affluent of the Sao Francisco) of 
the facetted pebbles ascribed to glacial action by Dr. Lisboa, (*) the 
eminent engineer and geologist of Petropolis, who has collected 
many of these from a locality north from my proper field of work, 
These facetted pebbles from 1 to 3inches in diameter, Dr. Lisboa 
regards as perfect fac-similes of those figured from the Dwyka 
conglomerate of §. Africa; hence, it is barely possible that Cors-

true glacial movements on the land at the north, and floating ice-
