with those who had advocated restricting the grades to Sernamby 

 and "Fine," eliminating the "Kntreline" type. 



Senhor Vianna Cuulinhn opposed the chniination of "iintrc- 

 iine" rubber, as there are regions which cannot produce the 

 latex required for the "Fine" grade. 



The resolutions linally adopted were : 



1. Tlie elimination as far as possible, of the "Entreline'' grade, 

 by the diffusion of the processes of smoking in sheets (.Amando 

 Mendes and Vianna Coiitinho), and of the chemical processes of 

 Cerqueira Pinto and others, when aiiproved by the governor of 

 the state. 



2. The elimination of the type of "Cameta Sernamby." 



3. The improvement of Island "Sernamby." 



4. The manufacture of Caucho by the Cerqiieira Pinto process 

 or other equivalent process. 



Considerable interest attaches to the above meetings. The 

 proposed establishment of a large association is doubtless ex- 

 pected to facilitate the carrying out of the various suggestions 

 which have lately been made for the development of the Brazil- 

 ian rubber industry. 



WASHING RUBBER IN MANAOS. 



A LETTER has just been received from Manaos — which 

 is reproduced below — which is interesting not only 

 because of its reference to the subject of washing machines, 

 treated at length 

 in the May issue 

 of The India Rub- 

 ber World, but 

 particularly as giv- 

 ing a concrete il- 

 lustration of the 

 new activity in the 

 Amazon rubber 

 country in the 

 campaign for pro- 

 ducing cleaner and 

 cheaper rubber, so 

 as to be able ti> 

 compete with tlu- 

 greatly increased 

 product of the 

 East. The sam- 

 ples referred to in 

 the letter look like 

 good, hard, dry 

 rubber, and if the 

 washing cost is 

 not too great the 

 work of these ma- 

 chines ought to 

 prove entirely sat- 

 tisfactory. 

 H.C.Pearsgn.Esq., 



Editor of The India Rubber World. New York: 



Dear Sir— In the issue of the India Rubber World dated 

 May 1, 1913, I noted with interest what you say about rubber 

 washing and washing machines on pages 396 and 411. 



As an interested party in the matter, I beg leave to state 

 that rubber washing is indeed an accomplished fact in 

 Manaos. .'\t about the time when the famous law about the 

 "Defesa da Borracha" was passed, I decided to try whether 

 it would be possible to find a suitable machine for washing 

 such rubber as comes to our market full of impurities, and 

 which suffers in consequence a heavy reduction in price. 

 For this purpose I took with rrie to Europe a certain quantity 

 of dirty coarse, and after having seen various other systems 

 of machines I visited Messrs. Werner & Pfleiderer in Cann- 



stadt, who showed me their new rubber washing machines 

 and washed in my presence the samples I gave them. As 

 the result was a satisfactory one I bought two of their ma- 

 chines. They offered me the agency for their machines in 

 Northern Brazil, which 1 accepted. 



The above-mentioned two machines have been installed in 

 the stores of the well-known firm of J. G. Araujo, of Manaos, 

 and were operated recently in the presence of his Excellency 

 the Governor of the State of .\mazon and the local super- 

 intendent of the "Defesa da Borracha," as well as of other 

 authorities and merchants. 



My object is not to wash line rubber, but only .such quali- 

 ties as would not find ready buyers in the consuming mar- 

 kets, i. e., dirty coarse, dirty caucho balls, etc.— which would 

 have to be sold at very low prices and would only impair con- 

 fidence in good qualities. By sending a clean and uniform qual- 

 ity to the consuming markets 1 hope to establish a standard 

 quality. 



Enclosed I beg to hand you some ijhotos showing the in- 

 stallation of the two machines, and by same mail I am 

 sending you a sample of washed coarse. 



I do not claim that the system is a perfect one as yet, and 

 I shall be thankful for any hint which may be useful for its 

 improvement. 



1 am, dear sir, yours very truly. Ph. Schl£E.

AMAZON EXPLOR- 

 ERS QUIT THEIR 

 SHIP. 



In the April is- 

 sue of The India 

 Rubber World 

 mention was made 

 of the expedition 

 sent out under the 

 auspices of the 

 University of 

 Pennsylvania for 

 the purpose of ex- 

 ploring the upper 

 tributaries of the 

 Amazon. The ex- 

 pedition set sail 

 on the 19th of 

 March, in the 

 Pennsylvania," a 

 jacht of 184 tons 

 burden. Unfortu- 

 nately, the "Penn- 

 sylvania" has not 

 lived up to expec- 

 tations. It sprang 

 a leak soon after 

 leaving Philadel- 

 delphia and had to put in at Newport News. It was also found 

 necessary to make further repairs on arrival at Charleston ; and 

 this experience was repeated off the Florida coast, so that they 

 put into Jacksonville, where they abandoned the yacht. The 

 expedition, however, will proceed to the Amazon, where a new 

 boat suitable for exploration purposes will be secured. 



DR. HUBEH AND THE TURIN EXHIBITION OF 1911. 



A banquet was lately offered at the Cafe da Paz, Para to 

 Dr. Jacques Huber and Seiihor Jayme Abreu, two of the three 

 representatives of Para at the Turin Exhibition of 1911. Ap- 

 propriate reference was made to the memory of the late Com- 

 mander Joao Rodriguez Martins, the third delegate, deceased 

 since the exhibition.
