oters, The only modification of our present intensive syrs- 

 ton required would bo tlio mapping O f types and sites and the 

 tallying of trees by cite Glasses as well as legal subdi- 

 visions. vlithout this additional information, however, our 

 present figures are of little value for tliis purpose. 



Discussion, in v/hioh Greenamyre agreed 

 tliat yield tables in virgin stance have 



.tlieir value, and said his statement re- 

 ferred to yield tables incut over areas; 

 that it is important to l~nov; e:::aotly 

 how much the growth will be increased 

 ei v i:0r the stand has been opened up for 

 cutting, and t?iat he thought this pros- 

 pective growth had been much underes- 

 timated in the past. 



Mitchell replied that he didn't under- 

 estimate value of gro\7th studios, but- 

 claimed that you can ! t gev the dope from 

 tract studios for 20 or 30 years, and 

 that measurements t alien at the end of 

 the SO years showing yield should suf- 

 fice without measurements during that 

 period; that at present wo are dealing 

 almost entirely T /ith virgin stands ;that 

 when cut -over lando become a factor we 

 can prepare tables for that condition; 

 that the information in growth suudios 

 is vei^ helpful but not comprehensive 

 enough on which to base irield tables 

 entirely.
