It should be carefully noted that the 

 figures obtained from the experiments of 

 Arthur D. Little Inc., seem to demon- 

 strate that the results obtained from the 

 measurements of fibre length and con- 

 tent of pitch for Jack Pine as against 

 Spruce, show that the Jack Pine is juUy 

 equal to Spruce in every respect. 



The following is an extract of the de- 

 tailed report by Arthur D. Little, Inc. : 



"FIBRE LENGTH AND PITCH." 

 The fibre length of pulp from Jack 

 Pine was rigidly compared with that of 

 Si^ruce and the results of our measure- 

 ments are as follows : 



Jack Pine Spruce 

 Maximum length of 



fibre 3 mm. 



Minimum length of 



fibre 1^/4 mm. 



Mean 2.26 mm. 



Percent of fibre 



over 2 mm 80 p. c. 



It will be observed that the fibres in the 

 Jack Pine are superior in length to those 

 of Spruce and should therefore be an 

 excellent substitute for the Spruce, 

 especially in connection with newsprint 

 pa])er. 



As the content of pitch in woods is 

 practically always an indication of their 

 behavior in either the sulfite or ground 

 wood process, we have made an ether 

 alcohol extraction of this Jack Pine to de- 

 termine the total resins and waxes. 

 Tliese were found to be as follows : 

 Alcohol extract . . . 2.28 p.c. 



X. Ether extract 30 p.c. 



2^/^ mm. 



1 V-i mm. 

 1 .92 mm. 



72) p.c. 



Total Ivits, Resins 

 and Waxes. . . . 2.58 p.c. 

 X. Ether extraction made successive to 

 alcohol extraction. 



Results of this analysis do not indicate 

 that an excessive amount of resin is pre- 

 sent and, furthermore, that this anK)unt 

 of resin does not necessarily ])reclude the 

 use of Jack Pine in the snitite process. 



It is to be hoped that any person who 

 has made experiments along this lino 

 will publish the results of the experi- 

 ments, for the benefit ot' all concerned.

Mr. Grainger Resigns. 



Mr. .M. A. Grainger, Chief Forester 

 of Bntish Columbia, has resigned to 

 enter private business. In making the 

 announcement, the .Minister of Lands 

 Hon. Mr. Pattullo highlv praised Air' 

 Gramger's work. '"He is a man of ex- 

 ceptional ability and the highest qualifi- 

 cations and his resignation will be keenly 

 felt in the forestry service." 



Mr. Grainger, who is an Englishman 

 by birth and a graduate of King's Col- 

 lege. Cambridge, having been twenty- 

 first wrangler in mathematics in 1896, 

 came to Canada the next year and partici- 

 pated in the famous gold stampede to the 

 Klondike. There he engaged in hvdrau- 

 hc mining, \\dien the South African war 

 broke out he returned to England and 

 enlisted as a private in Roberts' Horse 

 and served throughout the war. He pos- 

 sesses the Soutli African mc<!al with six 

 bars. 



After the war he returned to British 

 Columbia, where he spent some vears in 

 the mining and lumbering indusries. find- 

 ing time to contribute a number of arti- 

 cles to Old Country papers and also to 

 write an interesting book. "Woodsmen 

 ot the U'est," a work which accurately 

 depicted life in tlie lumber camps and 

 described the vast forest wealth of this 

 Province.
