. Effect of partial cutting in the virgin stand upon the growth and taper of western yellow pine . °a /o 20 3>a 40 30 <so 70 Fig. 6.—Comparison of actual tapers with the curved, by diameter-breast-high classes for average height. 5-inch diameter-breast-high class and 10-foot height class in which actual trees were found, and the volumes of each of these tapers weighted according to the number of trees in the class. The aggregate volume of the 285 trees is 854,600 board feet and the aggregate volume from the estimated taper curves 854,560 board feet, rendering a very satisfactory check. 7
