 Remarks. 



Grows at as high elevations as five thousand feet or more above 

 tide-water. Forms extensive forests with Balsam Fir 

 (Abies concolor). This, the grandest tree-form of the genus, 

 may be grouped, as to size, with Common Redwoods and other 

 giant growths. The immense cones, sometime? exceeding 

 eighteen inches in length, hang from the ends of the branches 

 and are very striking. The sugar-like exudations form an 

 active purgative known as "American false manna," and con- 

 tains a peculiar saccharine principle known as pinite.
