fought and extinj^iiished on l)oth Crown 

 and private lands, and it is interesting to 

 note that out of this large area only about 

 20,000 acres of timber lands were cle- 

 stroyed. 



During the past season the department 

 has employed crews of men to extinguish 

 over 150 fires and in addition about three 

 hundred small fires were extinguished Ijy 

 the regular patrolmen and rangers with- 

 out extra men before they had time to 

 spread, and still other fires were put out 

 by private individuals an;l lumber com- 

 panies. 



Permanent Improvements. 



Two look-out towers are equipped and 

 were used last season with good results, 

 several fires having Ijeen located from 

 ihcm. 



Tool caches are maintained at various 

 points, and all rangers are supplied with 

 tire fighting equipment. Ranger cabins 

 have been built at many isolated points 

 an 1 stocked w^ith fire fighting tools and 

 emergency rations. The fire protective 

 organization in Xew Brunswick has de- 

 veloped wonderfully during the last two 

 }-ears and plans are being made for much 

 further im]:)rovement in tlie coming year. 



The Pulping of Jack Pine 



Some years ago the W'ayagamack Pulp 

 & Paper Company Limited, Three 

 Rivers, Que., was equipped with com- 

 plete apparatus for the purpose of ex- 

 perimental pulping of all the dififerenr 

 species of wood. 



Experiments have been systematically 

 carried on for a number of years wiili 

 the object of discovering what different 

 species of wood were suitable for the 

 different qualities of pulp required for 

 the manufacture of all kinds of paepr. 



In the provinces of Ontario and Que- 

 bec there are enormous tracts of land 

 timbered almost exclusively with wh^.t 

 is know^n as Jack Pine, also called Bank- 

 sian Pine, or Cypress. 



For this reason, it was important to 

 ascertain if Jack Pine could be used for 

 the manufacture of sulfite pulp and 

 ground wood, in spite of all the prejudice 

 against i'^s use for this purpose. 



A preliminary examination of Jack 

 Pine, with regard to its resin contents 

 seemed to indicate that the resin was 

 not present in quantities which would 

 prohibit its use for the manufacture of 

 sulfite pulp or ground wood, although 

 Jack Pine seems to have had to carry 

 the blame for all the pitch troubles which 

 all paper mills suflfer from, more or less. 

 If Jack Pine is cooked in a mixture 

 with other wood, trouble is quite likely to 

 result, because Jack Pine apparently re- 

 quires a stronger acid and a longer cook- 

 ing time than other species of wood. 



If, however. Jack I'ine is cooked alone, 

 rlie company's experiments, as well as 

 those reported below, would indicate that 

 Jack Pine will produce a sulfite pulp 

 which is in all respects equal to Spruce 

 lulp. The fibre from Jack Pine was 

 found to be about .25 mm. longer than 

 Spruce fibre, wdiich will make it particu- 

 larly suitable for newsprint. 



Some years ago, by special arrange- 

 ment with Geo. INIcDougall, of the 

 Jacques-Cartier Pulp & I'aper Co., of 

 Pont Rouge, the Wayagamack 

 Pulp & Paper Company Limited, ship- 

 ped a quantity of Jack Pine to be pulped 

 into ground wood at the Pont Rouge 

 plant. 



The ptilp obtained from this wood 

 proved to be as good as, if not better 

 than, anything that could be purchased 

 on the market. 



The Wayagamack Pulp & Paper Com- 

 pany would like to call the attention of 

 the trade to the fact that from all the 

 experiments made, there is no evidence 

 of excessive pitch which coidd be traced 

 to the use of Jack Pine. 



By arrangement with Alessrs. Arthur 

 D. Little Inc.. of Cambridge. Mass.. sul- 

 fite cooking experiments were perform- 

 ed at their laboratory and the Wayaga- 

 mack Pulp & Paper Company have 

 pleasure in ])ublishing the principal re- 

 sults with the consent of the 'Arthur 

 D. Little Inc.. in the hope that the facts 

 will be of interest to the indttstry.
