FOREST COMMISSIONER'S REPORT. 



the measurements a certain answer to this question could hardly be 

 expected. I have however put considerable evidence together, and 

 it fosters the conclusion that the taper of the tree will not be thus 

 offset. I have concluded therefore that it would at any rate be 

 safe and tend to conservative results if in the case of all butt logs, 

 most of which are cut long, the area of the ring at the top end is 

 assumed equal to its area it any point below. 



Some general results of these calcu'ations have been given. It 

 remains to explain their use in ascertaining the growth on sample 

 acres. 



In the neighborhood of the first acre studied twenty- two trees 

 were measured and scheduled. Following the methods outlined, 

 the growth of each of them has been calculated. The results, divid- 

 ing the trees into size classes, are exibited in the following table, 

 where they are averaged. Then from the notes ou the acre the 

 number of trees is brought over by classes, and the necessary mul- 

 tiplications and discounts made. The final results are then stated, 

 and they need no further explanation. 



* Ti-ees measured in these classes were always choice trees, far above the aver- 

 age. 

 t This figure a mere guess.
