ONE CLUMP OP REDWOODS CONTAINING 250,000 PEET OF LUMBER; THIS GROUP OP 

 TREES IS GRAFTED TOGETHER AT THE TOP (SEE ILLUSTRATION, PAGE 523) 



The age of the redwood is about half that of the Sierra Big Tree, and the life of the 

 mature specimens ranges from 500 to 1,300 years. Some of the Big Tree specimens when 

 felled have been found to be more than 3,250 years old, and the General Sherman Tree 

 undoubtedly exceeds these in antiquity.
