FOSSIL FORESTS OF YELLOWSTONE PAEK. 



pieces of " kindling wood split from a clear-grained block. In fact, 

 at a distance of a few yards it would be impossible to distinguish 

 this fossil " kindling wood " from that split from a living tree. 



The large redwood trunk already mentioned (title-page) as being 

 nearly 10 feet in diameter may be compared with its living relative 



of the Pacific coast in order to calculate its probable height. The 

 living redwood is usually 10 to 15 feet in diameter and ranges in 

 height from 200 to 340 feet, and asthe two are so very closely related 

 there is no reason to suppose that the fossil trunk was of less height, 

 but by a moderate estimate it may be accredited with a minimum 

 height of 200 feet.
