GOVERNMENT MAXJ33 PAPIIR 

 FBOLI UEYf WOODS 



Washington. May 29: That satisfactory wood 

 pulp can "be made from a number of heretofore little known 

 woods is evidenced by a Government publication just issued, 

 which contains seventy samples of paper manufactured by 

 different processes, chiefly from woods heretofore practi- 

 cally unused for this purpose. 



It is pointed out that the spruce forests of the 

 country are threatened with exhaustion and that the cost 

 of spruce pulpwood has steadily increased. If the price 

 of news print paper is to ue kept at a reasonable figure, 

 say the experts, more efficient methods of converting spruce 

 into pulp must bo developed or cheaper woods substituted 

 for it. 



The bulletin goes on to say that the method of 

 manufacturing groundwood pulp has changed very little since 

 its introduction into this country in 1867. It was with 

 the idea of developing new methods and improving the old 

 that tests were undertaken at the Forest Service labora- 

 tories at \7ausau and Madison , Wisconsin. As a result the 

 relation of the different steps in the manufacturing pro- 

 cess to each other has been definitsly established and the 

 merits of each treatment determined. The paper made from 

 new woods was given a practical tryout by two large nev;s- 

 papers with satisfactory results. 



2he tests showed that eleven new woods give 

 promise of being suitable for the production of news print 

 paper, while a number of others will produce manila paper 

 and boxboards. Host of these woods are confined to i;he 

 West, while the groundwood industry now obtains the bulk of 

 its raw material from the East. It is thought that pulp- 

 making plants must eventually move to points where they 

 can obtain a plentiful supply of wood and an abundance of 

 cheap waterpower , two prime requisites in the business. 

 . 



Since the National Forests contain immense quan- 

 tities of the suitable woods and abundant opportunities 

 for power development, they will undoubtedly play an im- 

 portant part, it is said, in the future of the wood pulp 

 industry. 'white and red f.ir are the most promising spec- 

 ies in the National forests in California, although lodge- 

 pole and western yellow pine and Douglas fir may sometimes 

 be used.
