ASTONISHING RUBBER PROFITS. 



THE results attained by the older and better estab- 

 lished rubber plantations continue to exceed all 

 expectations. The 250 per cent, declared by the Vallam- 

 brosa company for their last business year again calls 

 attention to this most successful company. It may be 

 of interest here to recall briefly the history of the Vallam- 

 brosa, which has just completed its sixth year. 



Originally the owners of three neighboring estates in 

 the Malay peninsula got together and formed a com- 

 pany. Some rubber had been planted in 1898 and the 

 succeeding years, and they have been planting ever since. 

 The incorporators issued shares amounting to £45,000 

 [=$218,992.50] which they divided among themselves, 

 while they allowed others to subscribe for £5,600 

 [=$27,252.40] in shares, making a total issue of £50,600 

 [=$246,244.90], which is the amount of capital stock 

 now outstanding. 



The tapping of rubber was begun in the second year, 

 with the result that a profit was realized, though no divi- 

 dend was declared. During the succeeding four years 

 there has been a constant increase in the rate of yield, 

 both from a larger number of tappable trees each year, 

 £. and a more liberal average yield per tree. There has 

 £ been also a rapidly increasing rate of dividends declared. 

 During the last four completed calendar years the rub- 



ber collected on the Yallambrosa estates aggregated ' 

 1,025,867 pounds, and the dividends declared £222,640 *01 

 [=$1,083,477.56]. In other words, the shareholders 

 thus far have received in dividends 4 4/10 times the 

 amount of their investment. But what is more striking 

 than any given rate of dividend, dividends amounting to 

 slightly more than $1, gold, have been paid out for every 

 pound of rubber gathered. For the last year alone, 

 when the rubber crop was 370,902 pounds, the dividend 

 amounted to £126,500 [=$615,612.25]. This works out 

 at $1.66 profit for the shareholders for each pound of 

 rubber produced during the year. 



It is respectfully submitted that no other cultural in- 

 terest in the history of the world, under normal condi- 

 tions and in open competition, has ever shown such profits 

 as have been derived from rubber planting. Nor is it 

 conceivable, so long as these trees continue to yield 

 rubber, that any condition will ever arise in the trade 

 that can prevent such companies as the Yallambrosa from 

 being immensely profitable. 



As for some newer planting companies — but that is 

 another story. 



WHO INVENTED THE "PNEUMATIC?" 



A PROPOSAL to erect in Edinburgh a memorial to 

 the inventor of the pneumatic tire has given rise 

 to some dispute as to who was the real inventor. This 

 is not the first time that a dispute has arisen as to the 

 real author of an important invention or discovery. The 

 fact is that a really distinct invention is not, in its earlier 

 stages at least, a simple matter, however simple and com- 

 monplace it may appear to the general mind after its 

 development and widespread use. 



Such being the condition of inventions in general, it 

 may be asserted further that a really new article of utility 

 is seldom developed by a single mind, but is the result 

 of coordinated effort on the part of the inventor himself, 

 of engineers and factory superintendents who assist in 

 developing it, of his patent attorneys, the patent office 

 examiners, of the manufacturers who ultimately under- 

 take its production, and of an indefinite number of users 

 of the article. Every man of a practical turn of mind 

 who takes up the use of a newly invented article is liable 

 to make some suggestion bearing upon its possible im- 

 provement, or its better adaptation to its intended uses, 

 to the end that as long as the article remains in demand, 

 each year's output of it may possibly be better than the 

 preceding types. Many of the improvements so sug- 

 gested are likely to be covered by patents — often in the 

 name of the original inventor — but others, relating mere- 

 ly to details and not to new principles of invention, are 

 utilized as part and parcel of the original patent. 



To take the pneumatic tire, Robert William Thomson, 

 while the first patentee of such an article, cannot be 

 claimed to have produced a practical article of commerce. 

 His aerial wheel was regarded simply as an interesting
