Experiments on rubber tapping, W. Peel (Agr. Bui. Straits and Fed. Malay 

 States, 6 (1901), No. J/, p. 101). — The results of a series of ruliber-tapping 

 experiments carried on during the past year at the Singapore and Penang 

 botanical gardens are presented in tabular form. 



One old Para tree was tapped 14 times between November 19 and December 

 15, and yielded 4 lbs. 4* oz. of dry rubber, making a total of 35 lbs. 13* oz. 

 from this ti-ee since it was first tapped. Four othe*" 12-year old trees, tapped 

 14 times between July 11 and August 0, yielded a tf>tal of lbs. oz. of dry

Camphor production in Formosa and China, J. H. Arnold and S. L. Gbacey 

 (Daily Consular and Trade Rpts. [U. /S.], 1901, No. 2899, pp. 1-5). — According 

 to Consul J. H. Arnold, of Tamsui, camphor production in Formosa is confined 

 to trees at least 50 years of age, the cutting down of trees of a less age being 

 prohibited by the government. Recent investigations are said to warrant the 

 statement that the supply of old trees will at the present rate of cutting become 

 exhausted in less than 50 years. Owing to poor sanitary conditions, lack of 

 roads, and the presence of head-hunting tribes of savages, much of the material 

 in Formosa may not be harvested for years. During the present year the 

 Formosa camphor bureau, which controls almost a complete monopoly in the 

 production and sale of the world's supply of camphor, exi>fects to produce 

 G,6G7,000 lbs. of crude camphor, and about one-half of that amount of camphor 

 oil. 



A brief account is given of the work of afforestation being conducted under 

 the initiative of the government, together with the process of camphor manu- 

 facture, and some notes on marketing the product. 



Consul Gracey, of Fuchau, reports that in China the camphor trees are being 

 ruthlessly cut down as fast as they can be bought from the owners. A special 

 tax is to be imposed on the camphor and camphor oil produced, which will be 

 expended in planting and cultivating new trees. Five young trees are to be 

 planted for every tree cut down.
