Dr. Francisco de Paula Oliveira, First Engineer ; 
Dr. Benedicto dos Santos, Assistant Engineer ; 
Dr. Cicero Campos, Assistant Engineer ; 
Mr. Charles Mc. Carthy, Mechanical Engineer.

The Chief completed the reconnaisance studies in the field which 
as per contract were to end with February , 1906, and sailed for the 
United States on the 34 of the same morih, retiring as Chief at the 
end of his engagement, May 31st, rgo0. Since this latter date, Dr. Oli- 
veira has been the chief executive officer of the Commission. 
To Dr. Oliveira was assigned by Minister Miiller the duty of making 
all purchases of instruments, supplies, etc., and of attending to the finan- 
cial affairs of the Commission, while to Mr. Moreira was given the task 
of keeping the records, accounts, and books of the Commission, as well as 
acting as interpreter and general aid to the Chief. 
Dr. Seixas took charge of the surveys for an acurate map of the 
coal explorations around Minas, Santa Catharina, where the first field 
work was undertaken, and with the aid of Drs. Campos and Santos com- 
pleted the surveys for the excellent map of that region published sepa- 
rately as a part of this report. The drafting for this map was executed 
by Dr. Seixas from the field notes af Drs. Campos and Santos. He also 
added largely to the Commission’s collection of fossil plants while sta- 
tioned at Minas. 
Dr. Seixas had general charge of the test boring located at Minas 
by Dr. Oliveira after the latter left there with the Commission on Se- 
ptember 4th, 1905, until the former’s health failed and he sailed for Rio de 
Janeiro, October 15th, 1905. Dr. Santos then took charge of the drilling 
operations in Santa Catharina and successfully completed the boring to the 
granite, after which he moved the machinery to Cedro in the state of 
Parana by direction of Dr. Oliveira and sunk a bore hole there to a depth 
of more than 100 meters, demonstrating the absence of any beds of coal 
below the smallseam cropping at the surface.
