 Me a sin- erne nts plot tec": on "basis of diameter and height for 

 oacli site and curved heights used in determining the cord- 

 wood value of diameter classes. Zylometor measurements se-

 available shoeing cordwood values of different diameters re-

 thus given to getting diameter measurements.
