Other problems, Hiieli, for iu 

 stance?, as the deNi.siiig of a suitabU* 

 means for treating wood in euiupar- 

 atively small ipiantitien for use in 

 paving, tor smaller eoiumunitieh, 

 readily suggest themselves. The 



manuta<'turers of wood pulp aUo 

 liavc many problems of their own, 

 and it is apparent that were such a 

 laberatorx' established there woidd 

 be no la<d< of »|uestions for solution. 



Cordial support from nianufac- 

 lurers using wood is iiractieally luj- 

 sured. The Canadian .Manufactur- 

 ers Association has been approach- 

 «»l as to its attitude on the subject, 

 and is found to be favourable. So 

 unich in favour of the project is the 

 Lundternicn and Shingle Manufac- 

 turers Association of itritish Colum- 

 bia that they have already offered 

 to supply material gratis for tests. 

 ieariwhile the project continues to 

 make substantial, if slow, progreiw. 

 and it is hoi)ed that before lonir 

 Canada, too. will have establ-shed.
