INDIA-RUBBER INTERESTS IN EUROPE. 



RUSSIA. 



The General Electric Co., of Russia, realized during the last 

 business year a net profit of 511,470 rubles [=$263,407], as 

 against 439,050 rubles for the previous year. Dividend, 4 per 

 cent., against 3 per cent, last year. 



GERMANY. 



A NEW company has been registered at- Berlin, under the style 

 of Prowodnik Motor Pneumatic Gesellschaft m. b. H., for the 

 sale of the tires made by the "Prowodnik" company at Riga, 

 Russia. The capital is 20,000 marks [^=$4,764.20] and Georg 

 Philipp, of Gross Lichterfelde, is manager. 



The Continental Caoutchouc-und Guttapercha Co. (Hanover) 

 are reported as subscribers to the extent of 15,000 marks to the 

 fund for the benefit of Count Zeppelin, whose airship met a dis- 

 astrous end recently. 



GREAT BRITAIN. 



AT the last annual meeting of the Leyland and Birmingham 

 Rubber Co., Limited (Leyland, August 15), Mr. James E. 

 Baxter, the chairman, informed the shareholders that the year's 

 trading had been the best in the history of the company. He 

 reviewed the history of rubber prices as affecting the manu- 

 facture of rubber goods, but personally he did not anticipate a 

 repetition of the extreme fluctuation in the prices of crude rub- 

 ber such as they had experienced during the past few years, par- 

 ticularly when they considered the rapid strides which had been 

 made in the planting of cultivated rubber. The price would nec- 

 essarily settle itself down to a regular one, which would hand- 

 somely pay the planter, and which, at the same time, would 

 enable the manufacturer to produce at a fair profit, and also 

 to largely extend his business. 



At the last annual meeting of Dermatine Co., Limited (London, 

 August 25), the report to shareholders stated that the business 

 of the company continued to make favorable progress. It was 

 resolved to declare a dividend of 5 per cent, on the ordinary 

 shares, payable on September 14; the preference dividend of 5 

 per cent, was paid July 4, the total amounting to ^1085 &s. 6d. 

 [=$6,985.49]. 



The death is reported in London of Mr. Max Hecht, who 

 for a number of years was a partner in Hecht, Levis & Kahn, 

 from which firm he retired ten years ago, after having been an 

 important factor in the trade. He was in his sixty-fourth year. 



Equatorial Rubber and Mahogany Concessions, Limited, regis- 

 tered in London April 29, 1968, with £100,000 [=$486,650] capital, 

 to deal with rubber, gold, and timber in British West Africa. 

 Offices: 31 Lombard street, E. C, London. 



NON-DECOMPOSABLE CRUDE RUBBER. 



nPHE researches into the properties of crude rubber made dur- 

 ■'■ ing some years past by Mr. George E. Heyl-Dia have 

 yielded some results of much interest from a scientific standpoint 

 and of practical advantage to the industry. Recently, and after 

 a trip to rubber regions in South America, he has announced 

 the successful outcome of a new series of experiments, based 

 upon his observation of the treatment in the forest of Hevea 

 rubber. Mr. Heyl-Dia calls attention to the fact that the rubber 

 known commercially as "Cameta" is the product of precisely the 

 same quality of latex as "fine Para," though these rubbers are 

 quite unlike for factory purposes. The difference, he asserts, is 

 due wholly to the varying treatment received by the latex. 

 Based upon this principle Mr. Heyl-Dia's work has carried him 

 to a point where he contends that, by a certain treatment, any 

 rubbers may be improved, and that Africans and even guayule 

 may be made practically as good as Paras. 



Some time before Mr. Heyl-Dia had succeeded in developing, 

 as he asserted, the rubber molecule from balata and turpentine, 

 and later he introduced to the trade a specially treated guayule 

 rubber, of which a considerable amount has 'been sold. Now, 

 as a further step, he has brought out what he terms "non-decom- 

 posable" rubber, the result of treating ordinary crude rubbers. 

 The rubber so treated, as we understand it, is not mixed with 

 other gums or chemicals, except that the preserving process 

 prodttces at the same time greater strength. The destruction 

 of albuminous matter and proteins removes the cause of deteri- 

 oration in all rubber goods made from other crude rubbers than 

 fine Para.

[A rubber producing tree in Mexico, illustrated and described in The 

 India Rubber World. February i, i Q06 (page 148) and October i, 1907 

 (page 9). The tree botanically is designated Euphorbia fulva.] 



The directors of the Canadian General Electric Co., Limited, 

 declared the regular dividend of i34 per cent, on the common 

 shares, and the regular semi-annual dividend of 3}^ per cent., 

 both payable on October i.
