94 NEW BRUNSWICK FORESTRY CONVENTION 



ands, now being tossed high in the air by the swirling waters the touse of 

 the waves, or again held fast in the unyielding embrace of a narrow defile 

 until released by the daring lumbermen who follow closely on, and, too often 

 at the imminent risk of limb and life, seem to vie with each other in their 

 defiance of the forces which they bend to their will. And thus eventually, 

 the logs are gathered icto great booms wl ich stretch their corrugated areas 

 for great distances about the region of the mill. 



LOG PILE AT THE MILL 



Those logs which are not destined for immediate use, but are to be held 

 in reserve for future emergencies, are now hauled out and gathered into an 

 immense pile on the shore of the river, and from this store they eventually 

 find their way into the mill as required. From whatever source they may be 

 taken, the logs are drawn into the mill by an endless chain and imme- 

 diately cut into lengths of twenty - four inches. Thence by a similar

process they are transferred to the barking room, where every vestige of 

 bark is carefully removed. This is accomplished by firmly pressing the 

 rotating log against a rapidly-revolving plate which carries three blades in 

 its face. As a result the bark is quickly and completely removed. The now 

 decorticated logs are transferred to splitting knives, where they are halved 

 and quartered by the action of a vertical knife, and it is also at this stage of 

 the process that the first selection is made. All logs which show decay, 

 knots, or an undue amount of resin, are carefully culled and sent to the boiler 

 room, where they are used in firing. Not infrequently the splitting process 

 permits a portion of an otherwise useless log to be saved for pulp, and in this 

 way the material is not only carefully economised, but the high quality neces- 

 sary for the production of high grade pulp is fully maintained. Many of the de- 

 corticated logs are now store d for use in an emergency, as when from fire or 

 other cause, a portion of the machinery in the barking room has to be 

 stopped. Provision is thus made for the continuous operation of the mill 

 notwithstanding the disability of a given portion. The logs which are to be 

 immediately converted into pulp, now travel in two. directions by endless 

 chain, according to the particular kind of pulp to be produced. 



Speaking generally, two kinds of pulp are made, the mechanical and 

 the chemical. The former is the product of grinding processes intended to
