The small steamers which navigate during the dry season, have accommodations for first and third class passengers, are lighted by electricity, have an artificial ice plant and make the voyage from Manáos to Porto Velho and St. Antonio in about five days, at the average speed of ten miles an hour, calling at the small Amazonian ports and cities situated on the banks of the Madeira River. In descending the river both the large and small steamers make the voyage in from three to four days. The rubber from St. Antonio on the Madeira River is of the same physical and chemical constituents as all the rubber of the Amazon Valley. This is worth remembering, when we think of this new municipality in the State of Matto Grosso, being the frontier of the States of Amazonas and Pará. In the Manáos market, where the rubber comes by way of the Madeira River, and in that of Pará, which it reaches by way of River Tapajóz, it is always quoted at the same price and under the same conditions as those produced in the regions of the Amazon proper. The production has been increasing annually since 1906 and is actually about 2,000,000 of kilos annually. This will certainly increase to an amount that cannot be foretold, with the completion of the Madeira-Mamoré Railway, the wagon road and telegraph line and the constant improvements in navigation. During the first six months of the current year, the production of rubber was greater than for the same length of time in any year since 1907, as can be verified from the report annexed. In those regions, between Cuyabá and the new municipality, there exist rubber (seringa) forests capable of producing in one year, more than 40,000,000 of kilos of rubber. To attain this ideal, it is only necessary that the captains of industry should join in the development of extraction. This fountain shoots forth from the earth spontaneously without the necessity of cultivation. To encourage and stimulate those who wish to employ there, their endeavors and capital, the law of the State of Matto Grosso offers special favors. These are offered to those who wish to develop the vast forests of rubber existing, as well as to those who wish to plant and cultivate the =Syphonia elastica=. Speaking of the Rubber Exposition soon to be held in New York, it is proper to call attention to the well-known fact that already the capitalists of North America have begun the development of that region. The large capitalist, Percival Farquhar, of North America, has already incorporated two rubber companies, the Muller and Guaporé, under the social terms of July, for the purpose not only of developing the extraction industry of the =hevea= braziliensis, but also for the different branches of agriculture necessary for the making of sugar, cotton cloth, etc.
