SYLVICULTURE. 



case by far more frequently in primeval than in culled or cultured 

 high forest. Sometimes a distinct form of a minor, scattering 

 species appears to be " grafted ' upon a distinct form of one or 

 several major, gregarious species ("grafted forms"). Where two 

 distinct forms in mixture occupy more equal shares (not minor 

 and major shares) in the aggregate display, we may speak of 

 " wedded forms." " Husband and wife, though distinct individuals, 

 unite for a life in a household of their own."

I. Characteristic for all primeval forms is a relative preponder- 

 ance of the hypermature age-classes (veterans) ; a relatively 

 deficiency of the youngest age-classes (seedlings, saplings and poles) ; 

 the presence of a large number of dead, decaying or unsound speci- 

 mens only temporarily excelled in the " culled forms ; " a large 

 number of dead corpses of trees spread flat on the ground; irregular 

 confines of the parts composing the aggregates; irregular composi- 

 tion of such parts by age-classes and species, many of which may 

 be weeds; usually a heavy layer of humus on the ground; usually
