PONDING AS AN INDUSTRIAL TOOL FOR IMPROVING THE PERMEABILITY OF WHITE SPRUCE POLES TO CREOSOTE
White spruce poles which had been debarked and floated in fresh water for 12 weeks and air-seasoned for 13 months, were permeable throughout the sapwood to creosote impregnation by a pressure process. Treatments were carried out on a commercial scale in Newfoundland. Other poles which had been ponded with bark, sprinkled continuously, or air-seasoned were not uniformly penetrated. The order of effectiveness of the different methods of field-conditioning on a comparative scale is given.
