expressed as the percentage, by oven-dry weight, of pulp obtained from the original wood weight. A recovery value of 45% means that for every 100 oven-dry pounds of wood processed, 45 oven-dry pounds of pulp is produced. When expressed in this manner, pulp yield is mainly a function of the pulp-ing process. There is some difference between hard-
