The tree, however, has never been tested as a rubber yielder, 

 being wanted for seed-prod acing, and always since 1903 tapped 

 lightly. 



Its latex seemed to clot more readily in later years than in the 

 earlier. 



It is extremely probable that it was tapped between 1906 and 

 1909, but records have not been found. 



A plate in the Agricultural Bulletin, Vol. vii. 1908, issued with 

 the July number, shows the first spiral tapping of the tree and the old 

 herring bone scars. Another illustration of it from a photograph 

 taken a little later by Mr. H. Overbeck, occurs in Mr. E. Mathieu's 

 " Para Rubber Cultivation," 1909, page 125. 



Successive measurements of the bole of the tree at three feet 

 from the ground have been recorded as follows :— 



These figures indicate that its increase of growth during the last 

 five years has been at the rate of one inch in circumference per an- 

 num, and that for the five preceeding years it was at the rate of 

 about two inches per annum. 



When uprooted it was found to be 105 feet in height, which is not 

 unusual ; but as regards its girth we must count it an abnormality.

SEVENTEEN YEARS OF TAPPING IN THE 

 WATERFALL GARDENS, PENANG. 



In the Waterfall Gardens, Penang, there is a Para Rubber tree, 

 now 28 years old which has been tapped yearly since 1896, a record 

 being kept of its individual yield. A history of it is given on page 385 

 of volume I, 1901-02, of the Agricultural Bulletin of the Straits 

 and Federated Malay States, together with a plate. As the
