Information of this kind to supplement the 80 MANUFACTURE OF MECHANICAL PULP §3 freeness test would enable the grinder-room foreman to decidehow far to go with his dulling and sharpening operations,in an attempt to maintain constant a factor, such as freeness,which does not completely determine the operating qualitiesof a stock.
