tions. The rhrstnut inu>t le removed first, since it 

 grows more rapidly than the pine and will produce pole 

 and post material, while the pine is left for the final crop. 

 This mixture is a valuable one in the general range of the 

 chestnut. 



VI. White ash and red oak X 6 feet in equal mixtures. 

 These two species are very nearly equal in their rate of 

 growth and thinning may include both species. A well- 

 kept \\oodlot of this mixture can be depended on to furnish 

 saw timber from both oak and ash. This mixture is 

 adapted to moderately fertile bottom lands. 



VII. Sugar maple and chestnut in equal mixture 6X6 

 feet. The chestnut growing more rapidly than the maple 

 forms the overstory, while the maple shades the ground and 

 fonns the understory. Thinnings are made in both the 

 chestnut and the-maple. The chestnut is removed first, 

 leaving the maple for the final crop. This mixture can be 

 used in the northeastern states.
