ARTIFICIAL RUBBER. 
The synthetic preparation of rubber is generally believed by 
those who appreciate the extreme complexity of the compounds 
elaborated by nature, to be as far distant as the manufacture of 
artificial sugar. In view of the present uneasiness on this sub- 
ject which has been expressed by Hawaiian growers, we would 
direct them to the following expression by the Consulting En- 
gineer of the Xew Gutta Percha Company, copied from the 
Daily Mail (London) : 
"I have been approached on numerous occasions with samples 
of all sorts and descriptions of synthetic rubbers and so-called 
substitutes, some of which I have been led to subject to long- 
continued and exhaustive tests, the results of which, however, 
have only served to demonstrate the uselessness as substitutes 
for pure rubber or for the rubber compound owned by the corn- 
pan}- for whom I act I had the privilege, during the lifetime of 
Dr. Carl Otto Weber, of going exhaustively into the question 
of synthetic rubber with him, and the views he expressed to 
me on the possibility of producing rubber artificially by synthesis 
were decidedly and unequivocally adverse.'' 
KOOLAU RAILWAY. 
Eleven miles of the Koolau railroad, connecting with the 
Oahu line at Kahuku, will be completed by the end of this year. 
Already the extension is having a most stimulating effect on the 
agricultural development of that side of the island. Cotton, 
rubber and copra production are alike being projected by com- 
panies and individual settlers. A factory for the manufacture of 
manioca starch is in operation. Pineapple planting is projected 
on an extensive scale and canneries for that fruit will soon be 
established. Other things which grow well in the section are 
citrus fruits, peanuts, vanilla beans, soy beans and kitchen gar- 
den products generally.
