Ti)e Estimate. 



One of the most important steps in the preparation of a working plan 

 is the measurement of standing timber and of the rate of growth of the 

 more important trees. On these measurements are based tables giving 

 the present stand and the future yield, and from them conclusions are drawn 

 regarding the trees to be cut and the restrictions under which lumbering 

 should be carried on. The method by which were obtained the necessary 

 data on Township 40 for all the tables included in this working plan may 

 now be described. 



Compartments. 



To facilitate the estimate of standing timber, the township was divided 

 into six compartments, depending on and following the natural divides.
