THE INDIA RUBBER WORLD 



239 



Maranon, Ucayali, and Putumayo, besides a new rubber — "white 

 caucho" — from Moniti river. 



One stand was occupied by a collection of beautiful specimens 

 of rubber prepared by different processes — coagulation by means 

 of acetic acid, lemon juice, and so on, plain and smoked— in the 

 seringdl "Santa Maria," owned by Colonel Raymundo Monteiro, 

 on the Marmellos river, an affluent of the Madeira. There were 

 specimens on this stand fully equal in appearance to the best 

 Ceylon rubber, thus demonstrating the possibility of adopting on 

 the Amazon the methods successfully practiced in the Orient. 



Speaking of the Orient, the collection of implements employed 

 in the preparation of rubber in that part of the world embraced 

 the faca (sheath knife) invented by Dr. J. Huber, director of the 

 Goeldi Museum at Para, and regarded by many as the best 

 tapping tool for Hevea yet produced. 



As usual in Amazon exhibits the most showy part of the 

 exhibit were the great "pelles" of rubber from different seringaes, 

 and piles of "sernamby," caucho, and other varieties. One of 

 the best exhibits in this line was that of Rio Negro rubber, some 

 16 varieties, by Messrs. J. G. Aranjo & Co. The Peruvian 

 Amazon Co. also had a stand profusely adorned with photographs 

 of Indian tribes and so on. 



A word of mention should also be made of the exhibits of 

 rubber shoes, rubber covered bags, and the like, made by upriver 

 seringueiros, and representing the most primitive form of the 

 rubber industry. These articles are vulcanized by the very simple 

 process of mixing sulphur and gunpowder with the latex of either 

 Hevea or caucho, and then exposing to the sun's rays. 



A conspicuous exhibit was the machine for smoking rubber 

 invented by Mr. Manoel Vianna Coutinho, and the patent on 

 which belongs to the firm of Danin & Mello, of Para. This has 

 been illustrated in detail in The India Rubber World [September 

 I, 1904— page 413]. 



The exhibitors, as a rule, were not named on the labels on 

 the rubber displays, except in the case of that from Peru, which 

 was in the name of the chamber of commerce at Iquitos. The 

 descriptions of these exhibits, printed in Portuguese, cannot in 

 every case be identified with designations of rubber grades com- 

 mon in the world's markets. Thus the designation of the ex- 

 hibits from Tonkin (French Indo China) — "Soudan niggers" 

 and "Borracha vermelha Londres" — would require some explana- 

 tion in either England or the United States. The official de- 

 scription of the foreign rubber exhibits follows :

THE RUBBER MERCHANTS' DINNER. 



A very high compliment to the Editor of The India Rubber 

 World was the banquet tendered by the merchants of Para 

 (Belem is the official name of the city), on his return from 

 the Congress at Manaos. It was given at the Hotel da Paz, on 

 the evening of March 2, in a room decorated with the national 

 colors of Brazil and the United States. Placed about the room 



were tropical plants, including Hevea Brasiliensis. The tables 

 bore floral decorations. 



Senhor Jose Simao da Costa, the director in Brazil of the 

 Alves Braga Rubber Estates and Trading Co., Limited, acted as 

 toastmaster. His speech is reproduced here, together with the 

 response by Mr. Pearson. Other speakers were the American 

 and British consuls, and the representative of A Provincia 

 do Parti. 



Senhor da Costa's Address. 



Mr. Pearson — Gentlemen: The rubber merchants of the city thought it 

 their duty to show you their appreciation for all you have done to further 

 the interests of the rubber industry, to offer you the banquet at which we 

 are now entertaining you. 



We trust that, from all you have seen and heard 'during your stay in the 

 Amazon region, you will be able to form an exact opinion as to what the 

 future of wild rubber is likely to be, when it is known that this industry 

 is conducted on purely systematic commercial lines, and not in a hap- 

 hazard way as many people believe. 



Front of The Menu, 



We are all alive to the fact that tin se responsible for the rising rubber 

 industry in the east seem determined to make it a commercial success, and 

 we are indebted to them for the stimulus which their competition has 

 brought to our shores. 



History repeats itself every day that goes by, and what has happened 

 before, in many other industries, will happen in rubber. The advent of 

 electricity caused many well informed men to prophesy the absolute sup- 

 planting of gas as a street illuminant, but gas is as highly appreciated to- 

 day as it ever was, and gas companies were never better off, financially 

 speaking. 



The discovery of Marconi caused many people to believe that wireless 

 telegraphy would completely do away with all submarine cables, but these 

 are being now built with every assurance of remaining a permanent and 

 sound investment in the future. 



As with gas and electricity, so will it be with wireless telegraphy and 

 submarine cables. They will have distinct uses to fill, and will go on 

 progressing for the benefit of humanity, side by side, without injury, and 

 rather helping each other to meet the needs of modern civilization. 



So will it be in the rubber industry. There is room for all the rubber 

 that may be produced in the East, without injury to all the wild rubber of
