mercial size from both Rio Grande do Sul and Santa Catharina 
should be collected and shipped to other countries where laboratories 
for coal purification tests were already installed. 
Mr. Carlos Moreira, the Secretary of the Commission, accompanied 
hy the engineer Cicero Campos, returned to Minas, Santa Catharina, 
and secured several tons of coal from both the Bonito and Barro Branco 
coal beds, and then went to Rio Grande do Sul, and superintended the 
sampling of the mine operated on Arroiodos Ratos by the Companhia 
Iestrada de Ferro e Minas de Sdo Jeronymo, from which saveral tons 
were secured. 
These samples,thus taken under the direct supervision of members 
of the Coal Commission, were shipped lo the Humboldt lMngine- 
ering Works at Kalk, Germany, just across the Rhein from Cologne, 
where it was learned from previous correspondence was located one of 
the best laboratories of the old world for the testing of coals, as also for 
the installation of coal purifying machinery, and processes. 
Through the courtesy of Dr Walcott of the U. S. Geological 
Survey, another sample of the coal from th? S. Jeronymo mines, 
amounting to 20 odd tons was shipped to St. Louis for testing in the 
great fuel testing plant of the U. S. Geological Survey. This latter 
sample was selected by Mr. Otto Spalding, Superintendent of the S.Jero- 
nymo Company, who was instructed to send a general average sample 
of his commercial coal which he slips to Porto Alegre, Pelotas, Margem 
do Taquary and elsewhere for industrial purposes. 
Mr. Carlos Moreiracame to the United States in May, 1905, and 
later we sailed forGermany spending the month of June there in super- 
vising the purification tests made at Kalk by Lieut. Esser, the fuel 
expert of the Humboldt Engineering Works, who under date of July 
5th 1905 transmitted the following report upon the coal in question :
