Yield tables 1, 2, 3, 4 and 5 have been prepared as explained on 

 pages 97 to 104. All the yield tables are for one acre of normal, or 

 fully stocked, wood in solid cubic feet. The data in tables 6, 7, 8, 

 9 and 10 refer to all wood above ground, that is to say, exclusive 

 of roots and stools. 



To convert solid cubic feet into cubic feet according to quarter 

 girth measurement, take three-fourths of the volume given as 

 " Timber over three inches diameter at small end," or two-thirds 

 of the volume given under " Timber and fuel." These reductions 

 are sufficiently accurate for all practical purposes. 



I. Quality means the best which can reasonably be expected 



on good, fertile land. 

 II. Quality means an average quality. 

 III. Quality naeans the lowest quality of locality, on which the 

 species can reasonably be grown. It differs very con- 

 siderably accoi'ding to species.
