GERMAN ELECTRICAL PROGRESS. 



I K a summary ol progress in Germany a correspondent of 

 * the New York Journal of Commerce, writing from Hamburg, 

 says in regard to tlic activity in the electrical interest in that 

 country : 



"Another section of industry that has promoted the boom in 

 shares is the electrical trade. This industry is doing a splendid 

 business, and its prospects for future work and development are 

 bright. The Bavarian Legislature has recently passed a law 

 authorizing the development of an immense water power in the 

 mountains above Munich, and a company has just been organ- 

 ized tu develop a huge water power on the Rhine between the 

 Duchy of Baden and upper .Msace. German companies arc also 

 interested in new power plants now in course of construction 

 above Basle. One of the big Berlin electrical companies has 

 recently contracted to establish a power plant at Saarbrucken. 



"This same company, the Algemeine Elektrizitats-Gesellschaft, 

 is also about to bring a new electric lamp upon the market which 

 promises to eclipse the older kinds of arc lights. The .Mlgc- 

 meine controls the Gesellschaft fiir Rlektrische Unternehmnngen 

 at Zurich, and that company has recently taken steps to absorb 

 the Lahmcycr concern of Frankfort, another l)ig electrical estab- 

 lishment. This amalgamation is another important step toward 

 the elimination of competition in the German electrical industry, 

 as well as toward a sharper fight for foreign business. 



"For the first half of the year the exports of electrical goods 

 amounted to $24,000,000, against $19,475,000 for the first half of 

 1909. A number of establishments for separating nitrogen from 

 the atmosphere by electrical processes arc in course of construc- 

 tion in Germany, and in other countries, with German capital. 

 Next year such a plant with 120,000 horsepower will be com- 

 pleted at the Kjukan waterfall in Norway. In view of all 

 these promising features of the industry, the prices of electrical 



OIL FROM RUBBER TREE SEEDS. 



THE United States consul-general at Singapore suggests that 

 the oil of seeds of Hevea Brasilliensis will ultimately be ol 

 great commercial value. He recalls that it was a long time before 

 the oil of cotton seeds became a valuable commercial factor. 

 The consul general (Mr. DuBois) reports that at present there 

 is such a demand for the seeds of Hevea for planting that the 

 supply is not sufficient. It is now suggested by experts, however, 

 that in erecting machinery on new rubber plantations the plans 

 should be made with a view to rubber seed crushing machines 

 being included later. This would leave a residue on the estates 

 which it is believed will prove good for cattle food, as well as a 

 fertilizer for rubber trees. [United States Daily Consular and 

 Trade Reports, September 13. 1910. 1 



At a recent meeting of the United Planters' Association of 

 South India, Mr. R. D. Anstead mentioned that a large number 

 of the Para rubber trees planted in that country are already be- 

 ginning to bear seed, and each year more will do so. It has been 

 estimated that trees after the fifth year will yield 500 seeds each, 

 and the product of 400 trees will weigh a ton. It is stated that 

 the seeds contain about 20 per cent, of an oil which has been 

 valued at $100 (gold) per ton. Mr. .instead was of the opinion 

 that the planters should gather the seed, crush it for the oil, and 

 use the residue for fertilizing the rubber plantations. 



ADULTERATION OF LINSEED OIL. 



■"PHE recent high prices of linseed oil, says Iron Age-Hard- 

 *■ zvarc, has increased the use of adulterants to a considerable 

 extent. But it must be borne in mind that there are no crushers 

 of flaxseed — manufacturers of linseed oil — who adulterate their 

 product. All the adulterating is done by parties who buy the 

 pure oil. Small jobbers are mentioned as taking oil from a 

 barrel and replacing it with benzine or kerosene. Cotton seed, 

 corn and soya bean oils are also used as adulterants. It is esti- 

 mated that from 15 to 20 per cent, of the linseed oil now being 

 sold is adulterated. There are possibly few innocent purchasers 

 of adulterated linseed oil. The inducement of a price lower 

 than at which pure oil is sold is necessary to sell the "doped" 

 stuff. 



LOWER PROFITS OF LINSEED OIL. 



At the annual meeting of shareholders of the .American Lin- 

 seed Co., in New York, on September 13, the reports for the 

 fiscal year ended July 31 showed net profits of $720,952, against 

 $979,600 for the preceding year. Profits equaled 4.3 per cent, on 

 $16,750,000 preferred stock, compared with 5.85 per cent, earned 

 on the same stock in the previous year. The reduced earnings 

 are attributed to the smaller crop of flaxseed in the United 

 States, and the consequent higher price of seeds. The company 

 are working to develop a wider interest in flaxseed culture 

 among American farmers. 



One VVk.\k Spot. — "You ought to have your car equipped with 

 demountable rims," said an automobile man to ^.ichard C Jen- 

 kinson. the other day. "All you have to do is carry an extra 

 rim with inflated tire. In case of a puncture it can be easily 

 attached by a twelve-year-old child in two minutes." 



"Yes," said Mr. Jenkinson, "but the trouble is always to find 

 the twelve-year-old child." — Newark Neivs. 



DiiRiNG the crop year 1909-10 the Cicely Rubber Estates. 

 Limited, obtained 60,000 pounds of Ilcrca rubber from lo.ooo 

 trees, or an average of 6 pounds per tree. The average yield 

 was 1.3s pounds in 1905-06; 2.37 pounds in 1906-07; and 4.25 

 pounds in 1907-08.
