i The difference between this figure and the total number of measurements given as a basis in the different 

 ocalities is due to the inclusion of additional measurements from other localities in deriving the mean. 



LONGEVITY. 



Like most of the related species, incense cedar is a long-lived tree. 

 A few records of very large trees have been obtained, and trees from 

 300 to 500 years old are not unusual. The oldest observed was 542 

 t years old at the stump and measured approximately 51.2 inches in 

 diameter at breastheight. It is probable, therefore, that where it is 

 undisturbed it reaches an age of from 800 to 1,000 years. 



FORM. 



Incense cedar is characteristically short-bodied and rapid-tapering, 

 a feature which is accentuated as the tree approaches maturity by a 

 tendency to become buttressed and swell butted. This characteristic 

 is further exaggerated by the extreme thickness of the bark on the 

 lower portion of the bole, from 6 to 8 inches being not uncommon in 

 old trees. The relative form of the bole at different ages is shown
