 and wrapping papers. 



The Wausau laboratory will now 

 undertake the manufacture of ground 

 wood pulp from lodgepole pine, 

 western hemlock, western larch, west- 

 -ern yellow pine and white and red 

 fir. The use of these species for 

 ground wood pulp will mean much 

 to the provinces of British Columbia 

 and Alberta. 



Experiments in the manufacture 

 of chemical pulp are carried on in 

 the Forest Products Laboratory at 

 ^ladison, Wisconsin. This is the 

 largest and most complete laboratory 

 ■of its kind in the world. The buikl- 

 ing, costing $100,000, was erected by 

 the University of Wisconsin. The 

 equipment, statf and operating ex- 

 penses are supplied by the United 

 States Forest Service. 



The laboratory started work in 

 June of this year. The results of the 



work liave not yet licuii publislied, Imt 

 it is known that a good quality of 

 kraft paper has been manufactured 

 from the saw-mill waste of western 

 yellow pine, that the saw-mill w;:ste 

 of AVisconsin has been found satis- 

 factory for chemical pulp maniifac- 

 turc that great advances hav^ been 

 uuide in the manufacture of a good 

 quality of chemical pulp from dead 

 and green tamarack, hemlock and jack 

 pine. The staff at ^Madison have also 

 examined samples of pulp from prac- 

 tically all the mills in the country, 

 and have worked out satisfactory me- 

 thoils of standardizing, comparing 

 and grading wood-pulps. 



Similar work has been taken up in 

 India by the Imperial Forest Re- 

 search Station which is maintaine 1 at 

 Dehra Dun b^' the Indian Forest Ser- 

 vice. An experienced paper and pulp 

 man, AV. Raitt. has been retained by 

 the imperial government to investi- 

 gate the suitablity of diiferent Indian
