 being commented upon. The te.xt is supplemented by illustrations 

 of the "Ultimate" and other conveyor belts. Next in order come 

 conducting and garden hose, in which this concern specializes, 

 followed by steam hose, air drill and pneumatic tool hose and 

 other hose specialties. I-'ull details are then given of the "2V" 

 (Voorhees Vacuuml hose sold under that trade mark. Under- 

 writers' rubber-lined cotton and linen hose and the various other 

 makes of lire hose are then fully dealt with.

The numbers of the Bulletin of the above bureau up to Octo- 

 ber 31 are to hand. Among the iriost interesting articles in the 

 past issues are : "The Cultivation of Manitoba" and "Sources of 

 Rubber," by Dr. O. Labroy ; "Permeability of Vulcanized Rub- 

 ber," "Machines for the Rubber Industry," "The Situation of 

 the Rubber Industry," by Dr. Jose Bonifaccio; "The World'« 

 Rubber Production," Dr. O. Labroy; "Planting of Jequie 

 Mani(;oba" and "The Sale of Rubber," by T. C. Deutz. and 

 Manitoba in Hawaii." The October number (the last re- 

 ceived) has a number of interesting statistical returns, showing 

 the position of Brazilian rubber up to .August 31. 



Much care has evidently been given to the preparation of 

 the information contained in this bulletin. 



-■V special feature is the reproduction of the general catalog 

 of the recent exhibition at Rio de Janeiro, containing references 

 to the sources of the various saiuples exhibited, about 2,000 in 

 number. The bulletin thus forms a handbook to the rubber in- 

 dustry of Brazil.
