Actually the extraction of rubber in the vast seringaes of 
the municipality of St. Antonio of the River Madeira employ 
about 5,000 workmen. This number will constantly increase, as 
the said municipality becomes the center of the currents of com- 
merce, industry and agriculture, from Matto Grosso and the 
Republic of Bolivia. 
This is easy to imagine, when we see that the Madeira-Mar- 
moré Railway will place it in communication to the South with 
S. Luiz de Caceres, by means of the River Guaporé, and by the 
railway, which, from S. Luiz de Caceres will extend to the ancient 
city of Matto Grosso, thus joining the basin of the Plata—by 
means of the Paraguay River, to the basin of the River Amazon. 
And to the West the same Madeira-Marmoré Railway, reaching 
to Ribeira-Alta, will bind the vast and rich regions of the Boli- 
vian Republic to the basin of the Amazon, by means of the Ma- 
deira River. Presently the chief engineer and director of the 
Madeira-Marmoré Railway, Mr. H. Dose, will leave for that 
region, to begin the construction of the branch Guajara Mirim— 
Matto Grosso, to Ribeira Alta, Bolivia, which will be finished 
within a year and a half, and be about 100 meters long. 
In addition to this with the prompt construction within a year 
of the wagon—telegraphic line—roadway from Cuyaba to St. 
_Antonio on the Madeira River, we can easily conclude, that the 
municipality of St. Antonio on the Madeira River, will indeed 
become the converging point of these great and strong currents 
of development of progress and of civilization. 
In conclusion it should not be forgotten that this territory 
herein described serves not only for the production of rubber, 
which there, as in the whole valley of the Amazon, is native 
and grows according to the laws of nature. It also should be 
mentioned that cacao and cotton are native, while there can 
be planted and cultivated, sugar cane, coffee, vanilla, corn, beans, 
rice, tobacco, potatoes, brazil nut, etc. The Madeira-Marmoré 
Railway Company has the concession of a vast amount of land 
along its line, which it proposes to plant in cacao, sugar cane, 
etc., thus improving these lands. 
From this description, in which we have endeavored to set 
forth only the truth, giving the facts concerning the region in 
question, it can be concluded that the new municipality of St. 
Antonio on the River Madeira, which actually exports to the mar- 
kets of the world, via Para and Manaos, about 2,000,000 kilos 
of rubber, will in a few years, with immigration and from other 
causes, export from 10 to 15,000,000 kilos.
