Having finished the work at Cedro early in 1905, Dr. Santos re- 
moved the drilling machinery to Barro Branco Velho, in Santa Catha- 
rina, and drilled a well to test the presence of the Bonito coal bed, finding 
the same in good condition at a depth of 65 meters below the Barro 
Branco bed. Later he removed the machinery to the vicinity of Tre- 
viso, and sunk a test bore there. 
Dr. Cicero Campos, after the completion of the field work for the 
preparation of the map of the Minas region, rejoined the Commission 
on its return from Rio Grande do Sul in October, 1904, and accompanied 
the same in the subsequent excursions through Parana, S. Paulo, Minas 
Geraes, and Bahia. Later, in January of 1905, he accompanied Mr. Mo- 
reira to Minas, Santa Catharina, and S. Jeronymo, Rio Grande do Sul, to 
supervise the collection of samples of coal to be shipped to Germany for tes- 
ting purposes. During the season of 1905, Dr. Campos accompanied the 
Commission on its travels and studies in Rio Grande do Sul, Santa Ca- 
tharina, Parana, and S. Paulo, making a separate excursion down the Rio 
Tibagy to study and report upon the coal exposures and other rocks of 
that region. 
Later, Dr. Campos made an excursion to the valley of Rio Para- 
napanema, south from Avaré in S. Paulo, near the villa of Santo An- 
tonio da Boa Vista, at the instance of Capt. Manoel Marcellino de Souza 
Franco, in order to examine into the possibility of coal existing in that, 
region, returning with the report that the Jraty black shale, having flinty 
and bituminous layers, represents the supposed coal beds for which it 
has so often been mistaken. 
In March 1906, Dr. Campos by direction of the Chief returned to 
Santa Maria, in Rio Grande do Sul, in order to study and collect spe- 
cimens of the fossil reptile (Scaphouyx fischer?) discovered there by 
Dr. Jango Fischer. In this he was quite successful, securing a fair col- 
lection of bones which have been forwarded to Dr. Woodward of the 
British Museum for further study. 
On his return from Rio Grande do Sul, he selected a site for a 
coal boring test to be sunk near Ararangua in Santa Catharina in order 
to determine the presence or absence of the coal Measures there. 
Mr. Moreira, in addition to his general duties as Secretary of the 
Commission, always accompanied the chief in his travels, acting as aid 
in the field as well as interpreter and translator. In April, 1905, he came 
tothe United States, and accompanied the writer to Germany where the 
month of June was spent in supervising the test of Brazilian coal at 
Kalk, which had previously been shipped there under the supervision
