SINGAPORE SHARE CIRCULAR. 



I lie share circular nf Messrs. Fraser & Co., Singapore (issued 

 weekly), has .-oiuf to hand, and contains quotations for the 

 shares of about 75 leading Malayan rubber companies. Refer- 

 ences to the paid up capitals and latest dividends supplement the 

 other information of value to prospective investors. A detailed 

 table of monthly outputs shows at a glance the relative im- 

 portance of the respective companies. 



A DANISH RUBBER RECLAIMER ON THE SITUATION. 



In a neat booklet. Mr. -Albert Theilgaard, director of the re- 

 claiming works at Kjoege, Denmark, has summarized the prin- 

 cipal features of the reclaiming industry. When he took up the 

 work, some ten years ago, only a few brands of reclaimed rubber 

 were known, and manufacturers liad their own reclaiming plants, 

 which they regarded quite as necessary as their vulcanizers. 

 I'"ven now, however, reclaiming, according to the author's opinion. 

 is imperfectly understood by manufacturers, and they have so 

 many difficulties to contend with in their regular line of work 

 that they are better ofif by leaving reclaiming to special factories. 



Another difficulty consists in the fact that waste is steadily 

 deteriorating. 



It is in the interest of the manufacturer for the scrap to reach 

 the lowest possible level, but this, Mr. Theilgaard thinks, is im- 

 possible as long as hundreds of makers do their own reclaiming. 

 The hope is e,\pressed that they will see this plan is unsuitable 

 for small plants. 



Manufacturers have in some cases an objection to purchasing 

 reclaiined rubber, on the ground that they would have the 

 trouble of testing it. This trouble could, however, be avoided 

 by the employment of a chemist or a laboratory. They forget 

 that it is much easier to thoroughly test reclaimed rubber than 

 to reclaim it for themselves. 



Attention is called to the fact that scrap rubber has not fallen 

 in proportion to the crude article. This question was handled by 

 The Indi.^ Rubber World in its December issue, page 109, with 

 illustrative quotations; the article being quoted in Mr. Theil- 

 gaard's booklet. 



Air. Theilgaard adds that the prices of waste must be so fi.xed 

 that reclaimed rubber, will cost notably less than a compountl 

 of medium rubber of the same composition, otherwise, the manu- 

 facturer would prefer to take crude rubber, for which course- 

 no one could blame him.
