supply to the tip. A tree which has overtopped its fellows and has 

 actually outgrown its site is likely to become spike-topped during a 

 series of unfavorable years. In other words, it must "grow back" to a 

 height commensurate with the moisture of the site. 



Are not all of these height relations purely moisture relations? Is 

 not height simply an index to the density of the soil solution? To me 

 this seems to be the case, and hence I argue that while height is a 

 criterion of one of the most important qualities of the site, it does not 

 sum up all the qualities which the forester must be interested in and 

 which he attempts to express in the term "Site Quality."
