tion, the diameter breasthigh, the total height, and 

 the clear, used and merchantable lengths. The ob- 

 servations determine the class, form and condition of 

 the tree. Although a tree analysis may include many 

 combinations of the above measurements, two im- 

 portant classes are distinguished: A Stump analysis 

 includes measurements of the diameter growth at 

 given periods upon the stump only, no matter what 

 other measurements it may comprise. A Section 

 analysis includes measurements of the diameter 

 growth at given periods upon more than one section. 

 When, in a stump or section analysis, the measure- 

 ment of the diameter growth at given periods covers 

 only a portion of the total diameter growth, the 

 analysis is a partial stump analysis or a partial sec- 

 tion analysis.
