world, and is published in English, French and German. 

 It contains also a large number of receipts for vulcanizing 

 for various purposes in which we notice that Pontianac, 

 that is to say Jelutong plays quite an important part. 

 Many would be surprised to see how little of the rubber 

 goes into some of the cheaper vulcanized articles of every 

 day use. 



The booklet is more likely to be of use to the manufac- 

 turer and dealer in rubber articles than to the planter, but 

 to them it will doubtless supply a want in an efficient 

 manner. It is procurable from the office of the journal 

 above-mentioned, 49 Eue des Vinaigriers, Paris.

JOURNAL OF THE COOPER RESEARCH 

 LABORATORY. 



We have received a copy of the first Journal of this 

 Laboratory which is situated at Berkhampstead in England. 

 It is a well bound and illustrated book of seventy two pages, 

 dealing with the work of the staff, of especial value are the 

 experiments with Insecticides and Fungicides, use of lime 

 in Agriculture and Copper as a Fungicide. 



The staff do not only carry on researches of this kind 

 valuable as they are, but undertake inspections of orchards, 

 crops and stock suffering from disease, hold consultations 

 with Colonial Departments of Agriculture, Country Coun- 

 cils and such bodies and maintain a Museum of pests and 

 beneficial insects showing their life- histories and the 

 damage they do. The laboratory was founded by Sir 

 Richard Cooper in 1902, who is principal of the Laboratory, 

 and maintains a staff of twelve persons. The Director Mr. 

 Walter E. Collinge edits the report. Such experimental 

 laboratories are absolutely invaluable, and it is a cause of 

 surprise to many that we have so very few in our vast 

 Empire.
